When organizing large enterprise engaged in the supply of large quantities finished products wholesale buyers, it is better to register an LLC that gives more authority.

The entrepreneur must obtain permits from the relevant institutions.

Purchase of raw materials for the production of PP bags

Before purchasing raw materials for the manufacture of polypropylene bags, it is necessary to choose a manufacturing technology. The bags can be made from both virgin and recycled polypropylene. Recycled raw materials are recycled polypropylene products.

Consumables are supplied to the plant in the form of granules, the properties of which can be strengthened by adding special components during processing.

The choice of premises for the organization of a production workshop

It is not difficult to buy equipment for the production of polypropylene bags, since Russian market offers a huge number of machines and lines with different power, productivity, cost and dimensions. But before purchasing the equipment, it is necessary to prepare the premises for its installation.

The area of the room should not be less than 850 m2. The entire territory is divided into several zones:

the room where the polypropylene thread is made;
weaving shop;
area for cutting canvases;
warehouses for storing raw materials and finished products;
office.

wall and floor decoration with ceramic tiles;
the presence of a heating system;
good ventilation;
sewerage;
water pipes.

It is better to order the preparation of a production facility for work from specialists.

Selection of equipment for the production workshop

A standard line for the production of polypropylene bags, designed for the production of 150,000,000 items per year, includes the following devices:

drying and mixing machine
feeding unit;
extruder;
winding machine;
weaving machine for the production of polypropylene bags;
thermo knife;
Sewing machines;
printing machine for the production of polypropylene bags with a logo.

Over time, you can buy a lamination machine. The price of the machine is approximately 150,000 rubles. Separately, you will have to purchase a crusher, with the help of which the waste is disposed of, and a granulator for processing secondary raw materials into granules.

Purchasing equipment from local suppliers guarantees the availability of timely maintenance and repair of the line. The price of equipment for the production of polypropylene bags depends on many factors and varies from 3,500,000 rubles. Almost all of the elements responsible for line control are manufactured in Japan, which explains the high cost of the machines.

Equipment from China is much cheaper, but the quality of the equipment often fails. The price of the line, manufactured in the Middle Kingdom, varies from 270,000 rubles. and higher. The productivity of the equipment is from 3 to 30 million bags per year.

Recruitment of personnel for line maintenance

The purchase of the line will save on staff salaries, since only three people working in two shifts are needed to maintain it. The salary of one employee will be about 25,000 rubles.

The workshop will need its own manager, accountant, driver, 2-3 loaders. Equipment suppliers usually organize training courses to enable personnel to receive free training.

Features of the manufacture of PP bags

The technology for the production of polypropylene bags consists of several stages.

When dried, the necessary additives and colorants are added to the propylene granules. Calcium carbonate is used to make bags hard and snow white. After mixing, the composition is fed into the extruder.
The heated polypropylene passes through the packing and is cooled. The resulting thin film is cut into threads of a certain thickness, which are drawn after quenching and wound onto a reel.
On the weaving machine, the width and density of the weaving of the threads are set, after which a sleeve is made for the production of polypropylene bags, which is wound on bobbins.
The thermal knife is used to cut the sleeve into blanks, while the cutting line can be either flat or wavy.
The fabric is tucked up and stitched on a sewing machine with synthetic thread. The neck of the product can be either stitched or untreated.
With the help of sewing machines, a polyethylene liner is sewn into the bags.
Using a printing press, a logo is applied to the finished product, which can be color or black and white.

The last step is the packaging of bags of 500 pieces. The bundles are tied with twine and sent to storage.

Necessary initial investment and profit calculation

To open a mini-plant for the production of polypropylene bags in Russia, large financial investments are needed at the start.

Enterprise organization costs:

registration, obtaining permits - from 200,000 rubles;
industrial premises lease - from 1,000,000;

The total amount is 6,700,000 rubles.

The price of polypropylene is 45 rubles. for 1 kg. From one kg of raw materials, 14 bags are made, the cost of which is 3 rubles. Selling price - 10-12 rubles. The net profit will be about 400,000 rubles. per month.

Regular customers, well-established sales channels contribute to the fact that the company will begin to generate income in 15-18 months. Full payback - 2.5 - 3 years from the start of production.

Difficulties in organizing a business in the production of PP bags

Polypropylene bags are a fairly popular type of packaging. Therefore, the production of PP bags with a competent approach will provide the entrepreneur with a stable income.

To open a small workshop, you need to assemble a package permits and about 3,500,000 rubles. to organize a business. Large production will require more serious financial investments, time costs and special knowledge.

Part of the money will be spent on purchasing equipment, renting and preparing premises, and purchasing raw materials. The rest will have to be spent on the development of a business project and technical equipment of the plant.

There will be no problems with the sale of bags if, before opening a production workshop, an entrepreneur analyzes the state of the market, the capabilities of competitors and correctly identifies the target audience.

The article describes the organization of our own highly profitable production of polypropylene bags. The text is divided into subheadings: requirements for the premises, personnel, equipment, materials, production technology, business profitability.

Polypropylene bags are widely used in agriculture, construction for packaging building mixtures and materials, everyday life and household as inexpensive, durable and easy-to-use packaging.

Polypropylene bags are widely used in agriculture, construction for packaging building mixtures and materials, everyday life and households as inexpensive, durable and easy-to-use packaging.

Requirements for the premises

The start-up capital for the implementation of a business idea will be about 160 thousand dollars. The main part of these funds will be spent on the purchase of equipment and rental of premises; for production and storage areas, considerable sizes will be required - 800-1000 sq.m. A number of requirements are imposed on the workshop. The building must be at least 50 meters away from the residential area, the floor is concrete, the walls are tiled, ventilation, sewerage, heating systems must be present, and fire safety and labor protection rules must be met. The total area is subdivided into several production departments(this will include a workshop for the production of polypropylene yarn, a weaving and cutting workshop), as well as a utility and administrative premises, warehouses for storing raw materials and finished products. Preparation project documentation can be entrusted to a third-party organization. The cost of such services is estimated at $ 60 per sq.m.

PP Bag Making Equipment

The cost of the new automatic line for the production of polypropylene bags of Chinese origin averages 100,000 USD. excluding delivery and installation. It includes such main units as weaving looms, cutters, printing presses for applying advertising images, a laminator, an apparatus for producing flat polypropylene filaments of various thicknesses and widths, an extruder, equipment for processing plastic residues and waste after the manufacture of filaments.

Polypropylene

Granules of primary or secondary polypropylene are used as raw materials for the manufacture of bags from polypropylene thread. The choice of suppliers of the latter is very wide. The purchase price of 1 kg varies from $ 1 to $ 1.5, depending on the quality of polypropylene and the degree of purification from impurities.

Production technology

Polypropylene granules are mixed with dye and additives in a special bin. As the latter, calcium carbonate is used, which provides a beautiful white color and the necessary rigidity of the threads for the bag. The cost of the supplement in bulk purchase is about $ 2 per 1 kg.

The mixed components enter the extruder, under the action high temperature the mixture is melted and squeezed out in the form of a thin film, after cooling it is cut into threads, which are wound on the coils of the circular loom, and here the fabric base is formed - the sleeve of the bag. Then the fabric is cut with a hot cutter, the edges are edged or stitched, and the neck is also processed. Finished products are packed in packs of 500-1000 pcs., Pressed to reduce the volume and transferred to the warehouse. An additional source of income can be the use of the sides of the bag as an advertising platform and other images. This procedure is carried out using a flexographic printing press with the option of mono or full color printing.

Staff

To maintain the line, a staff of 2-3 workers will be required. Salary costs will average 1800-2000 USD. per month.

The profitability of a business idea

The cost of making one polypropylene bag is estimated at $ 0.09. Wholesale price - $ 0.25. Considering that 14 finished products can be made from 1 kg of granules, the monthly profit of the enterprise can reach 7.5 thousand dollars with active sales and large deliveries to construction, agricultural and agricultural companies.
Low cost of materials, excellent mark-up, high demand for the final product and the possibility of using secondary raw materials allow us to consider the business of manufacturing polypropylene bags as a promising, profitable and profitable direction of activity.

For storage, transportation and packaging of food and non-food products, polypropylene bags are often used. They have a fairly low cost and widespread use. Polymer packaging is practical and greatly simplifies the sale of products. Such packaging is more often used for packaging bulk food products (sugar, salt, cereals), fertilizers, and building materials. The maximum weight of the contents of the bag depends on the size and density of the bag and can reach several centners.

The production process of polypropylene bags consists of several stages:

1) cleaning and extrusion of the film for the web;
2) obtaining a canvas;
3) cutting of bags;
4) applying logos;
5) sewing bags and packaging.

For greater strength and reduce the slipping of bags in the hands, special additives are used that make the fabric rougher, and the threads for sewing products more durable.

For the production of polypropylene bags, the following equipment is used:

1) dispenser;
2) extruder;
3) circular loom;
4) machine for cutting the web and stitching and edging;
5) filling machine.

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. The rent will cost about $ 1100 per month. The repair and connection of communications will require approximately $ 2000.

Polypropylene bags production technology

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 required density and stiffness. If the bags are white, calcium carbonate is perfect 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 cooling takes place, 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 go to the weaving machine, where they are connected into a sleeve of a given size (the width of the bag depends on this). Then the product is wound on bobbins;
With the help of a thermal knife or a semiautomatic machine, the sleeve is cut into blanks of a certain size, from which bags are sewn;
Branding, logos and inscriptions are made before the final product is sewn. At this stage, black and white or color print on blanks;
Sewing 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 conditions storage and can lie in the warehouse for quite a long time.

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

Among Asian companies, inexpensive lines are offered by HAO YU Precision Machinery Industry Co., Ltd. (Taiwan), Mitra Trading (China). High-end Japanese equipment costs from 15 thousand dollars. Chinese can be purchased for $ 4500-5000. Its average productivity is 250,000 items per month.

Raw materials for the production of polypropylene bags

The main material is primary or secondary polypropylene. Secondary is recycled polymer products; it is sold in granules and is cheaper than primary. A month for the manufacture of 250 thousand units, you will need about 20 tons of consumables.

With a wholesale cost of a 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 requires 8 people: four workers (equipment operators), a manager, a manager for receiving raw materials and shipment of finished goods, a cleaner, an accountant. That's roughly $ 4,000 in payroll per month.

Costs and Benefits

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

Registration - $ 70;
Lease 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.

Opening investment- in the region of 32 thousand dollars. Fixed costs: rent, wage, utilities and the purchase of consumables (16 thousand dollars per month).

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

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

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

On the modern market where demand gives rise to supply, inexpensive, durable and sealed packaging - polypropylene bags - has become in great demand. The business of manufacturing 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 household 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 - far from a complete list of goods, for the transportation and storage of which these products will become indispensable. Their main advantages are:

durability - reusable;
impermeability to moisture - availability of use in warehouses and basements;
resistance to chemicals;
compactness - when empty, it is very light, practically does not take up space;
resistance to climatic changes - 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 their versatility in use finally pulls the arrow of 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. By recyclable materials, we mean polypropylene that was previously used in other products and has already been processed. During the production of polypropylene bags, 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, which are distinguished by high performance characteristics and durability;
from secondary polypropylene with the addition of primary - gray products, which are less durable;
only from secondary raw materials - PP bags of green color, inferior in quality to the top positions, used for transporting waste.

Product prices 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 constitute manufacturing process where each procedure affects the final result:

PP bag table

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

Preparation of raw materials

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

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

Extruder EPK 45 × 30

Getting flat yarn

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 cross-section. The resulting film is cooled, expanded into strips, which are hardened and drawn into flat threads of the required width.

Winding machine

Making a woven sleeve

Polypropylene fabric in the form of a sleeve is obtained by weaving threads on a 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, the sleeve can be wound in close proximity to the next production line.

Cutting of blanks, rolling and stitching

The next procedure in the manufacture of polypropylene bags is to give the product a form 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. Subsequently, the bottom of the bag is formed on the blanks by twisting and stitching. A strong nylon thread is used for sewing.

The products are stacked 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 the raw mixture from the bunker;
an extruder that plays a major role in the production of flat filament;
a weaving machine that turns a polypropylene thread into a sleeve from a fabric with the desired weaving density;
line with a device for hot cutting of workpieces and sewing machines;
flexographic printing machine.

Units for the production of polypropylene bags

Among additional equipment starting electrical devices, lighting devices, automation, control and protection equipment will be needed. In the process of development of production, 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, removal 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 rest of the requirements are explained by the specifics of the production of polypropylene bags.

The working area should provide a free location industrial equipment preserving 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 cross-section, power of the distribution substation).

The service personnel must have utilities (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, and other administrative activities. Therefore, when choosing a building, you need to pay attention to the availability of premises for an office.
