Plastic bottles: PET production. Raw materials for the production of PET bottles: main properties and features Costs for the production of paper bottles

Plastic containers for drinks have recently been in great demand. You can pour juices, mineral waters, carbonated drinks, beer, and other alcoholic and non-alcoholic drinks into it. Therefore, organizing a business for the production of plastic bottles is considered quite profitable. This will require an automated bottle production line, a workshop where it will be located, and maintenance personnel. For businessmen who produce a variety of drinks, it makes sense to purchase equipment for making containers and carry out this process themselves. Thanks to this, you can save up to 25% on plastic container costs.

Features of PET bottles

Plastic bottles began to be produced in the 70s of the last century; DuPont was the first to produce this type of container. At that time, this became a revolutionary invention, and the bottles themselves seriously competed with glass bottles. Today, glass bottles are rapidly being replaced by plastic ones due to a number of reasons:

But plastic also has its disadvantages:

• it allows ultraviolet radiation and oxygen to pass through, as a result of which the contents lose their characteristics and the shelf life is reduced;
• it releases carbon dioxide, which is especially important for carbonated drinks, kvass and beer.

Necessary raw materials for production

Polyethyl

The main source material is polyethylene terephthalate - PET, thermoplastic. When exposed to high temperatures, plastic molecules polymerize - they combine and form larger compounds, which increases the volume of raw materials. Dyes are used to give the product the desired shade. During the production process, some products are rejected, in this case the percentage of defects will be high - up to 25%, it can be processed, using it as raw materials. Thus, waste-free production is obtained.

Room

Workshop for the production of plastic containers To accommodate a line for the production of PET bottles, you will need a room with an area of ​​more than 40 m2, a ceiling height of 4 m, during its preparation fire safety requirements must be met, since furnaces are used, the temperature of which during operation rises to 200 o C. Therefore, it is advisable to line the walls and floor with tiles or non-combustible materials, concrete. The workshop must have three-phase sockets with a voltage of 380V. All utilities are required - water supply and sewerage, air conditioning, ventilation. Separate warehouses will be needed to store raw materials and finished products. To organize a small enterprise focused only on the production of plastic containers, it is not at all necessary to purchase real estate; it will be much more economical to rent production space.

Production equipment

There are two types of plastic bottle production lines:

• single-phase, when the process of making the preform and blowing the container occurs in one place, while the preform will maintain a high temperature;
• two-phase, when preforms are made on one machine, and then the line operator manually transfers and loads them into a blow molding machine. At the same time, the preforms cool down, and the blowing apparatus needs to heat them up again.

Components of the automated line:

• PET platform;
• bake;
• automatic bottle blowing machine.

The PET platform is designed for the formation of preforms by heat treatment of polyethylene terephthalate granules. Characteristics:

• number of nests – 6;
• mold thickness – up to 240 mm;
• power supply – 380 V;
• power – 73 kW;
• dimensions – 2000*950*2480 mm;
• weight – 250 kg.

A conveyor-type oven, as part of a PET bottle production line, is designed for heating preforms. Uniform heating is ensured by eight active zones, due to which in the future the product will be blown into the correct shape and the percentage of defects will be reduced. Specifications:

• productivity – up to 1200 pcs/h;
• power – 8 kW;
• voltage – 380 V;
• dimensions – 1270*520*1220 mm;
• weight – 260 kg.

There are two types of automatic blow molding machine:

• for the manufacture of containers with a volume of 0.2 to 5 liters;
• for the manufacture of containers with volumes from 5 to 19 liters.

Thanks to the high speed of hot air supply, the blowing process is carried out very quickly, and the bottle is of the correct shape. Characteristics:

• power – 5.5 kW;
• productivity – 700 pcs/h;
• blowing pressure – 14 atm;
• dimensions – 1800*500*1000 mm;
• weight – 250 kg.

The cost of a line for the production of bottles of this configuration will be 800 thousand rubles.

Manufacturing technology

Two-phase blowing line

At the first stage of the production cycle, it is necessary to form preforms - blanks. First, the raw material, polyethylene terephthalate, is heated; it comes in the form of granules, which, under the influence of high temperature, increase in volume and combine into a homogeneous mass. Then the hot mass is poured into metal molds, which can be standard, the most common, or can be made according to an individual project, then the finished product will have an original design. The filling process must be carried out as quickly as possible so that the molten mass is evenly distributed throughout the mold. If this stage is performed correctly, the finished product will not be deformed.

In the next step, the preforms are cooled using liquid carbon dioxide, or water cooling is also possible. Next, the blanks are sent to a blow molding machine, where the bottle formation process is carried out under high pressure, up to 30 atmospheres. Thanks to high pressure, the entire process requires a minimum of time, and the product is obtained in the desired shape and size.

The next stage is quality control; all products with visible deformations are subject to removal and further processing. The bottle production line can be supplemented with an automatic shredder for recyclable materials and defective products. Thus, making production waste-free and saving on raw materials.

Business Features

Setting up your own enterprise for the production of PET containers will not require significant capital investments. To start you will need no more than 1.5 million rubles.

Heated preform under pressure takes any shape

During the production process, the main expense item will be staff salaries. Three workers will be required, a loader, a driver, a manager, an accountant and a supervisor; it is possible to combine management positions into one. Another significant cost item will be utility bills - during production there is a large consumption of electricity, since all the equipment has a fairly large power. There will also be a significant consumption of water for cooling preforms and finished products.

Despite high competition, this type of business is considered highly profitable; the cost of a bottle production line can pay off within six months of equipment operation, provided that the finished product is fully sold. This can be achieved by concluding agreements with manufacturers of drinks, juices, and draft beer.

Equipment for the production of PET bottles It will also make it possible to establish an independent, highly profitable business for the supply of containers to small businesses, since the number of water and beverage producers in Russia is constantly growing.

Technology for the production of plastic bottles (Blowing PET containers)

The raw material for blowing PET bottles is a blank with a fully formed neck - a preform, produced on an injection molding machine (injection molding machine) from the feedstock - granulated polyethylene terephthalate (PET). Using equipment for blowing PET containers under the influence of heat, a bottle ready for bottling is formed from a preform. This process is presented in the diagram below.

The Packing Group company offers ready-made, well-functioning technologies and the supply of a full range of blowing equipment: automatic or semi-automatic blowing, compressors, air preparation systems (cooling, moisture removal, filtration). If your company is focused on independent production of PET containers, contact us in any available way.

Nowadays, plastic bottles are an indispensable packaging for beer, kvass, water and many other liquids. The main material for their production is polyethylene terephthalate.

Today, even in small settlements, enterprises for the production of beer, soft drinks and food products are often built and successfully operate. But in this area it is impossible to do without plastic containers. In this connection, almost all manufacturers have no choice but to purchase plastic bottles from other manufacturers at high prices. However, if you delve deeper into their production, you can conclude that the process of their manufacture is not something abstruse and impossible. And if you look at the technology and prices for equipment for the production of plastic bottles, you can forever eliminate the purchase of such containers “outside”.

Equipment for the production of plastic bottles

Naturally, producing any materials yourself is much cheaper than purchasing them from manufacturing companies. And plastic containers are no exception. In fact, organizing production is a fairly easy process. As in all areas of industry, the production of PET containers will require special equipment. It can be divided into the following groups:

• Preforms;
• Bake;
• Quartz lamp;
• Blowing machines;
• Double mold.

Preforms represent a special basis for the production of bottles. They are produced using polyethylene terephthalate granules by shaping them under pressure and high temperatures. Such container bases, in turn, can be divided into the following types:

• Universal;
• Thick-walled;
• Shortened.

Making plastic bottles using different types of preforms allows you to get a variety of bottles that will differ from each other in shape and color.

Bake for the production of PET containers it is used to heat preforms to the required temperature. Additional options for such equipment include rotation of the workpiece and its movement, which provides more effective softening and, as a result, ease of giving the required shape.

quartz lamp plays a key role in the heating process of the preform in the oven.

Blowing machine used to inflate the already softened base of a plastic bottle (preform) and form its final appearance. Such equipment must necessarily include a compressor. This machine for making plastic bottles must be equipped with a special protection against overheating of the neck, which preserves the precise thread for screwing on the cap.

Double mold capable of creating a plastic product of absolutely any appearance. Most often, high-pressure casting technology is used to produce containers from polymer materials.

Plastic packaging created in this way is almost weightless and absolutely transparent, which is ideal for storing and selling all kinds of liquids. In addition, this container can be made in many colors and also have different shapes.

Also, the process of manufacturing plastic bottles itself will not require huge financial costs or a large area for production. In other words, the production of plastic bottles is a process whose positive aspects can be listed for a very long time.

Plastic bottle production technology

As mentioned above, the process of manufacturing plastic containers is quite easy to implement. This is precisely why the production of PET bottles in factories producing beer or soft drinks is so popular. And this is not surprising, because there are simply a lot of positive aspects of such production:

• First of all, this activity is not at all expensive;
• Companies, by independently producing containers for their products, can reduce the cost of their goods;
• The appearance of plastic bottles can be made very original and unlike others.
• The container release process is fully automated;
• Due to the fact that it is quite difficult to break plastic bottles, there is no need to use special boxes for them, which also makes it possible to save money on transportation and sales.

The process of making plastic bottles itself occurs using internal inflation molding. This method has evolved over time, and today it is simply ideal for every manufacturer.

Stages of making plastic bottles

The production process of PET bottles takes place in several stages. First, a blank called a preform is made on an injection molding machine from the raw material (from polyethylene terephthalate granules). It is a small-sized blank with an already formed threaded neck.

Next, the workpiece heated to a certain temperature is placed in a prepared mold and a special steel rod is placed in it. Under high pressure, air enters the workpiece, evenly distributed along the walls of the future container, creating a certain shape.

In performing this stage, it is extremely important to achieve the same air pressure at all points on the surface. The most effective results can be achieved by spending minimal time on the process. This is the only way to avoid possible deformation of a finished plastic bottle.

After shaping, the finished product should be cooled using air or liquid carbon dioxide. The concave bottom of the bottle and its convex inner part make such a container stable on a flat surface.

The final stage of plastic bottle production is to remove all possible defects that could appear as a result of the flow of molten plastic. After this, the finished products are sent for sorting using a moving container.

It is important to note that during the production of plastic containers, almost a quarter is discarded due to defects and is recycled.

The role of recycled materials in the production of plastic containers?

Recycling of secondary waste is a truly serious topic that concerns not only the environment, but also significant cost savings for the production of primary products. In the last few years, our country has made a breakthrough in processing recycled plastic waste.

Nowadays, plastic bottles are the most popular secondary raw material for the production of plastic polymers. And if just recently a huge number of plastic bottles were thrown away or burned, today the situation is getting better.

Unfortunately, container recycling has not yet reached perfection; every day it is developing more and more. The only negative aspect can be considered the lack of plants for processing plastic waste.

If you pay attention to the statistics, residents of a small city with a population of around 100 thousand residents throw away more than 20 tons of plastic bottles every month. In addition, the amount of waste increases by about 1/5 every year. And if recycling such raw materials were impossible, the country would face a real environmental disaster.

If we talk about more developed countries, then for them waste recycling is a valuable and profitable process. In Shanghai, for example, recycling of secondary raw materials is so developed that, before you have time to throw plastic containers into the trash, they will immediately pick them up for recycling. In our country, in turn, the lack of necessary factories is the main reason for the large number of PET bottles in landfills.

Modern technologies make it possible to obtain excellent raw materials from plastic waste for the production of almost any container. This principle has found wide application in many countries, creating a waste-free production cycle.

Machines for making plastic bottles

Used for the production of plastic containers by drawing and two-stage blowing. Using such a machine it is possible to produce bottles with a capacity of 0.25 to 2.2 liters with a productivity of about 3000 bottles per hour. The products have found their application for storing carbonated and still liquids. This equipment consists of the following parts: a loader of blanks (preforms), a heater, a manipulator and a power unit.

Semi-automatic equipment of the MV series makes it possible to produce containers up to five liters. Such devices consist of a heater and a pneumatic mold former. The device is used for the production of plastic containers by heating followed by blowing. Consists of a power unit and a heater.

Such a powerful device as the isobaric filling triblock DXG 18-18-6 is designed for filling a wide range of liquids. The wide functionality and high performance of this device practically eliminates the need for maintenance personnel.

Main types and advantages of PET bottles

Types of products

The classification of PET bottles is based on several parameters of the finished product. The main ones are the following:

• Light transmittance. The container can be transparent, darkened, matte. In the first case, it is used for bottling lemonade, juices, and vegetable oils. In the second - for the sale of low-alcohol drinks, balms, tinctures of medicines. The purchase of opaque plastic bottles is most often relevant for manufacturers of household chemicals and car products.
• Wall thickness. Selected depending on the purpose of the container. If bottles made from PET will be used to store non-aggressive substances, then standard products (0.1-0.5 mm) will be suitable. Household chemicals must be poured into multilayer containers containing polymer. For highly carbonated drinks, containers are produced that contain nylon (passive barrier). In cases where you have to work with reagents, you need PET products that are resistant to UV rays (active barrier).
• Volume. Plastic bottles vary in volume. You can order large containers or buy small-volume PET bottles.

Advantages of bottles made from PET

This container is very convenient for storing and transporting liquids of almost any kind. The basis for production is polyethylene terephthalate, a material that is now actively used for the manufacture of containers in which both drinks and food are stored.

Plastic containers for liquids are in high demand, which is explained by a number of its advantages:

• Ease of use. During transportation, the likelihood of damage to PET bottles is minimal.
• Variety of shapes. The practical application of modern technologies makes it possible to obtain containers of different designs. Preforms are used (PET bottles are blown) or the extrusion method.
• Possibility of branding. Labels and other advertising products can be glued to the surface of plastic bottles.

We have been producing PET bottles for many years and can fulfill orders of any level of complexity.

What determines the price of PET bottles?

The pricing factors when selling PET bottles are:

• volume;
• features of the PET used (regular, multilayer, etc.);
• equipment (presence/absence of lid and handle);
• specifics of the order (small, medium, large wholesale).

It is difficult to imagine the life of modern people without plastic bottles, since they are the most common and popular type of packaging. Enterprising people have long learned to profit by building their business on the production of such products. In this article we will introduce you to the features of the production of plastic bottles, equipment for the production of plastic bottles, and also tell you how to start such a promising and profitable business from scratch.

Business Features

Today, the production of plastic bottles in Russia is considered one of the most profitable areas of business activity. Literally 20 years ago, no one could even imagine that carbonated drinks, water, milk, juices, beer, etc. would be sold in PET containers. Today, plastic containers are used in a variety of industries, so such products are always in demand on the market. But you can’t count on an easy start in such a business, since the level of competition in this segment is constantly growing.

It is worth noting that equipment for the production of plastic bottles, the price of which is quite high, is characterized by high energy intensity. For example, an automatic machine that makes 3 thousand bottles per hour consumes 25 kW on average per hour of operation. This will require a powerful compressor with a pressure of at least 40 bar. If you want to start such a business, be prepared to spend a lot of money on purchasing equipment and paying electricity bills.

Another important point is the mass of the blank for the production of plastic bottles. The cost of finished products largely depends on this. The highest quality equipment that can be used to make liter PET bottles from preforms weighing no more than 35 grams.

Advantages and disadvantages

Pros:

• The low cost of producing plastic bottles allows them to successfully replace their glass counterparts. This container is shock resistant and easy to transport. Many manufacturers of juices and carbonated drinks no longer buy PET bottles from intermediaries, since they produce such containers themselves. They gradually expand production in order to sell surplus and cover their expenses with profits;
• The production of plastic bottles will flourish because a better and more environmentally friendly material has not yet been invented. This means that any novice businessman can open a fairly profitable and promising business in this area;
• Inexpensive raw materials. If you want to reduce the cost of finished products, you can organize the collection of secondary raw materials from the population.

Minuses:

• Large starting investments;
• High level of competition.

Business plan

The first thing you need to do is draw up a business plan for the production of plastic bottles. Until you calculate future costs and benefits, it is impossible to determine the profitability of a project.

1. Calculation of initial investment. Start-up investments must cover all costs for the purchase of equipment for the production of plastic bottles, raw materials, payment of utility bills, taxes and salaries to employees. In addition, it is necessary to provide for the costs of repairing the production premises, as well as arranging a warehouse and staff room;
2. Market analysis. This important point should not be overlooked when opening any production. If someone in your city is already manufacturing plastic bottles, ask whether they fully satisfy the demand for such products, check the quality and find out for what purposes their containers are intended. It is most profitable to open the production of plastic PET bottles on the basis of an enterprise that produces bottled water, juices or sweet carbonated drinks. Thanks to this, the cost of finished products will decrease by 20%. Excess plastic containers can be sold and receive additional income from this;
3. The profitability of such a business is quite high, since the raw materials for the production of plastic bottles are inexpensive. To transport such products you will not need special boxes. If there is a need to change the shape and size of the product, you can simply take another mold;
4. Promotion of production. The business plan must include points for business development. First of all, it is necessary to notify customers that a new player has appeared on the market. You need to do everything to ensure that the consumer knows about your product, otherwise the business will fail.

Before you start drawing up a business plan, you need to study the production technology of a plastic bottle. We'll talk about this in the next section.

Technological process

There are several ways to produce plastic containers:

• Extrusion method. Using this technology, different types of hollow containers are made from granular thermoplastic material;
• Vacuum forming method. It is used to make correxes, blisters, cups, etc.;
• Blowing method. Used for the manufacture of polyethylene and polypropylene bottles.

In general, the technology for making plastic bottles looks like this:

• First, they buy molds for the products. Each type of container has its own design and size;
• The raw materials are melted in a receiving hopper and injected into molds under pressure. Further, the process depends on what type of container you want to receive. You can immediately cool the product and remove it from the mold, or the workpiece is placed in a matrix, where further molding is carried out. A vacuum is created in the matrix, as a result of which the product takes the desired shape. After this, the matrix must be cooled and the finished bottle removed from it. To produce such products, you can use secondary raw materials, crushed using special equipment.

The largest percentage of defects appears at the blowing stage, so you need to carefully monitor the air temperature and check the integrity of the thread after blowing. Only the most expensive automatic lines can fully ensure product quality. To solve the problem with defects, it is necessary to test each batch.

Necessary equipment

Before you buy equipment for the production of plastic bottles, you need to decide what you will need for the job:

• Preforms;
• Bake;
• Blowing machines;
• Double press mold.

Preform is the basis for making bottles. They are produced under high temperatures and pressure from polyethylene terephthalate. The basics are divided into the following types:

• Thick-walled;
• Short;
• Universal.

Thanks to this variety, you can make different bottles that differ in both shape and design.

The oven is designed to heat preforms to the required temperature. This equipment also has additional options - movement and rotation of the workpiece. Thanks to this, it softens more effectively and, accordingly, easily takes on the desired shape.

The blowing machine creates the final shape of the bottle. This machine is equipped with a compressor and special protection that prevents the neck from overheating and preserves the threads intended for screwing on the cap.

Using a double mold you can create any plastic product. Often, high-pressure casting is used to produce polymer containers. Products made using this technology are completely transparent and very light. They are perfect for packaging various liquids. Such containers can have different colors and shapes. The video production of plastic bottles will help you get acquainted in more detail with the operation of the equipment.

As a raw material for the production of plastic bottles, a preform made of granulated polyethylene terephthalate is used. This thermoplastic is obtained by heating polyethylene terephthalate granules to a certain temperature. When reheated, this material does not collapse or deform.

A preform is a blank of a bottle in which the neck has already been formed. The finished product is blown out of it. Special equipment is used to produce preforms. Most often, bottle manufacturers purchase preforms as raw materials. In this case, there are two enterprises in the production chain. Typically, manufacturers of various drinks work according to this scheme, making their own plastic containers. They believe that it is much more profitable to purchase preforms than to set up their production at their own enterprise.

When choosing a preform supplier, be sure to find out what material the product is made from. If this is recycled recycled material, that is, waste, food containers cannot be made from such material. It is only suitable for the production of bottles for technical liquids.

Personnel and production premises

The area of ​​the room and the number of service personnel depends on what equipment you will use for work. For example, if you install the simplest equipment, you will need three workers per shift and about 60 sq. meters of area.

The production facility should consist of the following departments:

• Manufacturing facility;
• Administrative part;
• Staff room;
• Warehouse for raw materials;
• Premises for finished products;
• Bathroom.

The total area of ​​the workshop must be at least 100 square meters. meters. With a three-shift operating mode, it is necessary to maintain an accountant, 9 workers, a driver and a manager on staff.

Financial investments and profits

Purchasing an automatic line for the production of plastic bottles will require a serious financial investment from you. With a competent marketing policy, all investments will pay off in the shortest possible time. Let's try to roughly calculate how much money it will take to open a mini production of plastic bottles:

• Registration of permits – 200 thousand rubles;
• Purchase and installation of equipment for the production of plastic bottles – 3 million rubles;
• Repair and preparation of production premises - 300 thousand rubles.

Also, don’t forget about monthly expenses:

• Salary – 250 thousand rubles;
• Taxes and utility bills – 120 thousand rubles;
• Purchase of raw materials – 100 thousand rubles.

On average, the wholesale price of one unit of product (when purchasing a batch of over 10 thousand pieces) is in the range of 3.5–4.5 rubles, the cost of producing a plastic bottle is 1.7–2 rubles. If the enterprise operates in two shifts, it will be able to produce 200 thousand units per month. If there are sales markets, you can receive 340 thousand rubles of net income monthly. Full payback of the project occurs after 1 year of work.

Profitability

Entrepreneurs who produce glass containers know that the minimum volume of products must be at least 1 million units, otherwise the enterprise will be unprofitable. Modern technologies make it possible to turn on a machine for the production of plastic bottles for 1 thousand pieces.

If you compare the weight of a PET bottle and a glass container, you can understand how much money you can save on shipping costs. Such products do not break and do not require the purchase of special boxes for transportation. Plastic bottles are available in a wide range of colors, and to change the design or size you just need to take a different mold.

A profitable system for recycling PET bottles at home. We are drawing up a business plan for recycling plastic bottles. Business registration and equipment.

We are opening the production of paving slabs from plastic bottles. Technology and methods of manufacturing tiles in production. Requirements for the premises of a mini plant.
