The building is best rented on the outskirts of the city to avoid problems with the delivery of consumables and the export of the finished product. Rent will cost approximately $1100 per month. Approximately $ 2,000 will be required to repair and connect communications.

Production technology of polypropylene bags

The production process includes several steps:

Raw materials (polypropylene in granules) are dried and mixed in a special machine with dyes and other additives. The main additive is calcium carbonate, thanks to which the bags acquire the desired density and rigidity. If white bags are produced, calcium carbonate is the best for this;
The resulting mixture enters the extruder, where it turns into a homogeneous hot mass;
The hot mass is passed through the hole of the extruder head, then it is cooled, and as a result we get a thin film;
The film is cut into threads of a given thickness, they are pulled out and carefully wound onto bobbins;
Then the fabric part is made. The resulting threads are fed to a loom, where they are connected into a sleeve of a given size (the width of the package depends on this). Then the product is wound on reels;
With the help of a thermo-knife or a semi-automatic device, the sleeve is cut into blanks of a certain size, from which bags are sewn;
Branding, application of logos and inscriptions is carried out before the tailoring of the final product. At this stage, black-and-white or color printing takes place on blanks;
Tailoring is carried out on special sewing machines: the bottom is sewn up, the neck is processed. To increase the density, you can insert a polyethylene layer inside the product, sewing it to the neck;
Package. The finished product is packaged in bags of 100, 500 or 1000 pieces. A big plus of these products is that they do not require special storage conditions and can lie in the warehouse for quite a long time.

They are well suited for flour, sugar, construction debris, sand, cement, various feeds, grains and cereals, fertilizers, etc. Therefore, the product is popular and versatile. It is designed for weights of 5, 10, 20, 50 kg or more.

Raw materials for the production of polypropylene bags

The main material is polypropylene primary or secondary. Secondary is recycled polymer products, it is sold in granules and is cheaper than primary. It will take about 20 tons per month to produce 250 thousand units consumable.

With a wholesale cost per kilogram of $0.5-0.6 per month, you will have to spend about $10,500 on the purchase of pellets.

Staff

In two shifts, the plant needs 8 people: four employees (equipment operators), a manager, a manager for receiving raw materials and shipping finished goods, a cleaner, and an accountant. That's about $4,000 in payroll per month.

Costs and profits

To create a full-fledged mini-factory, you need the following investments:

Registration - $ 70;
Rental of production space for three months in advance, repairs - $ 5300;
Line for the production of polypropylene bags, purchase and installation - $ 5500;
Purchase of consumables for two months - $ 21,000.

Investment in opening- in the region of 32 thousand dollars. fixed costs: rent, wage, public utilities and the purchase of consumables ($16,000 monthly).

Wholesale unit price- 0.1-0.15 $. A package with a thousand units will cost $100. Therefore, the monthly revenue will be 25 thousand dollars, and the net profit - 9 thousand.

Products should be offered to wholesale trading companies, construction and industrial firms, warehouse complexes, and farms.

Based on the above calculations, the production of polypropylene bags, even on a small scale, requires considerable investment, but pays off very quickly. Within six months, the company will begin to bring the owner a high stable income.

In the modern market, where demand creates supply, inexpensive, durable and sealed packaging containers - polypropylene bags - have become very popular. The business for the manufacture of these products is profitable, so the costs of opening it, including the arrangement of the premises and the purchase of equipment for the production of polypropylene bags, can quickly pay off. This is due to the popularity of this type of packaging in various economic and industrial sectors.

Reasons for the increased demand for polypropylene packaging

Polypropylene bags are a convenient and practical container for any bulk materials. Building mixtures, animal feed, fertilizers, foodstuffs, cereals are far from a complete list of goods for the transportation and storage of which these products will become indispensable. Their main advantages are:

wear resistance - the possibility of reusable use;
impermeability to moisture - availability of use in warehouses and basements;
resistance to chemicals;
compactness - when empty, they are very light, practically do not take up space;
resistance to climate change - with temperature fluctuations environment do not lose their qualities.

But the main advantage of PP bags is affordability. Their price compares favorably with the cost of other types of packaging, and the versatility in use finally pulls the scales to its side.

Raw materials for production

The basis of the material is granular polypropylene, which can be of primary or secondary origin, which affects the quality of the product. Recycled material refers to polypropylene that was previously used in other products and has already been recycled. During the production of polypropylene bags, the granules are mixed with other components that give the material strength and elasticity.

Depending on the feedstock, the following types of products can be produced:

from primary material - white bags, characterized by high performance and durability;
from recycled polypropylene with the addition of primary - gray products with less strength;
only from recycled materials - green PP bags, inferior in quality to the top positions, used for transporting waste.

Prices for products vary depending on the raw materials used in the manufacture.

Technological processes in the production of polypropylene bags

The release of finished products is preceded by several stages, which individually are not particularly difficult, but together they make up manufacturing process, where each procedure affects the final result:

Table of polypropylene bags

A separate stage in the manufacture of polypropylene bags is the application of a pattern with a logo and name on a flexographic machine.

Raw material preparation

In the drying machine, polypropylene granules are mixed with other fillers, among which the chemical compound of calcium and carbonic acid salts (CaCO 3 - calcium carbonate) occupies an important place. This component acts as a dye and at the same time gives the material the necessary rigidity.

After that, the mixture is sent to the bunker, and then to a special machine for plasticizing (softening) - an extruder.

Extruder EPK 45×30

Getting a flat thread

In the extruder, the mass is heated, and under the action of the press it is pushed out through the extrusion head, which is a profiling tool. It gives the material a flat section. The resulting film is cooled, unraveled into strips, which are hardened and drawn into flat threads of the desired width.

Winder

Making a woven sleeve

Polypropylene fabric in the form of a sleeve is obtained by interlacing threads on the machine. Its parameters (thread tension, warp feed, width) are set depending on the desired result. The product is produced as a continuous sheet, which is wound on bobbins. They are obtained with a large diameter and for their movement to the place of further processing, it is necessary to use special equipment. To simplify the task, it is possible to wind the sleeve in close proximity to the next production line.

Cutting blanks, turning and stitching

The next procedure in the manufacture of polypropylene bags is to give the product a shape corresponding to its purpose. For this, the PP sleeve is rolled out on a special line, where it is cut into pieces of equal length (blanks) by means of a thermal knife. The cut can be straight or curly, resembling a zigzag. In the future, the bottom of the bag is formed on the blanks by turning and stitching. For stitching use a strong nylon thread.

The stacking of products is carried out automatically in several hundred pieces. Each bundle is tied with twine and sent to the warehouse.

Equipment used in production

In addition to the above machines for drying raw materials and winding coils, in technological process you will need a lot of special equipment for the production of bags:

a feeding unit that automates the supply of raw mix from the bunker;
an extruder, which plays a major role in obtaining a flat thread;
a loom that turns a polypropylene thread into a sleeve from a fabric with the desired weaving density;
line with a device for hot cutting of blanks and sewing machines;
flexographic printing machine.

Units for the production of polypropylene bags

Among the additional equipment, starting electrical devices will be needed, lighting, means of automation, control and protection. In the process of production development, there will be a need to purchase other units, but at the initial stage the listed machines will be enough.

Features of the choice of premises for production

The activity of the enterprise provides for the presence of industrial noise from operating equipment, as well as active traffic (delivery of raw materials, export of finished products, waste disposal). Therefore, one of the requirements for the premises for the workshop is a sufficient distance from the residential area.

The remaining requirements are explained by the specifics of the production of polypropylene bags.

The working area should provide a free location industrial equipment while maintaining space for the safe movement of people.

Machines and mechanisms are powered by electricity, so the room must provide for the supply of electricity in the required volumes (cable section, power distribution substation).

It is obligatory for service personnel to have communal communications (heating, water supply, sewerage) and a ventilation system.

Vehicles need parking and maintenance: a garage must be available for this purpose.

The development of an enterprise largely depends on high-quality planning, accounting and analysis of costs and profits, work with customers and partners, other administrative activities. Therefore, when choosing a building, you need to pay attention to the availability of office space.

The production of polypropylene bags is organized on modern compact production lines. The relevance of opening such a business is confirmed by the wide demand for finished products. Food and non-food bulk materials, construction and household waste need inexpensive, durable packaging for transportation and storage. Polypropylene packaging perfectly copes with such tasks, and the costs of creating such a production are quickly paid off.

The relevance of the production of polypropylene bags

Polypropylene bags are durable industrial packaging. It is characterized by resistance to abrasion, the possibility of repeated use, water resistance, versatility and low cost. Differs in the type of raw materials:

white bags made from virgin polypropylene. Used for transportation and storage of bulk food products: sugar, flour, salt, starch;
gray produced from recycled materials with the addition of virgin polypropylene. Less durable than white, suitable for transport and storage building materials and waste, pelleted feed, fertilizers and chemicals;
Green produced entirely from recycled materials. Slightly inferior to gray in strength. Used for the disposal of construction debris.

Industrial activities related to the production of PP bags are in high demand. The wide possibilities of such packaging and the low price allow it to be used in high demand at construction companies, agricultural firms, representatives of the food and chemical industries.

Business strategy

Before organizing industrial production: rent a room, purchase equipment, hire employees, even at the stage of developing a business plan, it is worth analyzing ways to sell finished products. The main consumers of products:

Any production is not complete without marriage. For the processing of waste and products that have worked out their time, there are special devices. The purchase of a crusher for plastic recycling and a granulator will help organize the process of recycling polypropylene. Recycling- an important component of the environmental program for the disposal of industrial waste.

Business organization

Since the manufacture of PP containers is associated with the processing of polymeric raw materials, the location of the production workshop should be removed from residential buildings. The best option when creating a plant, it is considered the lease of a suburban premises with the possibility of its subsequent redemption into ownership.

When organizing production, mandatory technical requirements to the equipment of the workshop is the presence of:

Good ventilation system;
Necessary communications (water, heat and electricity, sewerage);
Cleaning air filters.

The amount of space required depends on the dimensions of the purchased equipment. On average, a production line occupies 50 m². It is necessary to provide storage facilities, rooms for staff, a garage if delivery of finished products is planned.

On the domestic market presents a large selection of machines for the production of polypropylene bags, machines and devices. You can choose the one that suits your power and price. The system of leasing equipment with subsequent purchase has proven itself well. The price of a fully equipped line with a capacity of about 4,000 items per shift will be at least 3,500,000 rubles.

To maintain a high-quality, automated line for the production of polypropylene bags, at least six people are needed, three people in two shifts, with salary 25000 rubles per month.

The approximate amount of capital investments is as follows:

The cost of equipment is 3,500,000 rubles;
Delivery and installation of the production line - 350,000 rubles;
Purchase of granules - 320,000 rubles;
Registration in tax office, payment of monthly rent, overhead costs - 280,000 rubles;
Total - 4450000 rubles.

If you plan to organize a garage, you need to add at least 1,500,000 rubles to this amount.

The amount of fixed monthly expenses consists of:

Salaries of six employees - 150,000 rubles.
Social payments to the wage fund - 45,000 rubles.
The cost of renting a workshop is 110,000 rubles.
Administrative payments - 60,000 rubles.
Other expenses - 100,000 rubles.
Total - 465,000 rubles.

Technological stages

The main stages of production:

Mixing and drying of raw materials. Primary and secondary polypropylene granules are mixed with dyes and necessary additives. Often calcium carbonate is used. It gives the package a white color and the desired rigidity. The finished mixture is fed into a polypropylene extruder with a flat slotted nozzle and heated to 260 °C.
Production and winding of a flat thread. The heated mixture passes through the nozzle in the form of a thin film. After cooling, it is cut into flat threads of the required thickness, hardened, drawn and wound on coils.
Fabric production. The circular loom is adjusted to the required parameters: the thread weave density and width are set. The resulting polypropylene sleeve for making bags is wound onto large reels.
Cutting. The finished polypropylene fabric is cut into blanks by hot cutting. The cut line can be straight or wavy.
Manufacturing end products . A special device, from the bottom side, folds the polypropylene fabric for bags the required number of times and stitches it with a strong synthetic thread. The neck is left unfinished or stitched. In some cases, polyethylene liners are sewn to the bottom.
Logo laying on. The flexographic machine applies a polychrome or black and white logo to the finished product.
Package.Finished goods stacked in packs of 500 or 1000 pieces, pressed, pulled with twine and stored.
