Range of products.
Of course, paper packaging has been made for a very long time, but like everything in the world, the well-forgotten old turns into a new thing. This happened with kraft paper.
What kind of material is this, and how is it made? This is a dense, durable and mechanically resistant paper made from raw materials such as long-fiber softwood cellulose. The raw material is obtained by cooking wood chips in sulfates.
Sulfate method of pulp production
This is the method used by most pulp manufacturing companies.
First, the wood is sawn, the bark is removed and ground into chips in special machines. It is the latter that is boiled in large cauldrons in a mixture of sodium salts and caustic soda. During cooking, delignification occurs - a decrease in the strength of the wood, as a result of which it goes into solution - and cellulose remains.
Wide use this method is associated with factors such as low production costs, since some of the reagents used in this technology can be reused. In addition, the process produces by-products that are used in industry.
The technology allows you to process any type of wood, and even waste, and this process takes a short period of time. This significantly reduces the cost of the final product.
Advantages of Kraft Paper
Your name this type packaging material was derived from the German concept kraft, which is translated into Russian in several versions - power, energy, effort and force. And each of them is suitable as a definition of basic properties. Kraft paper has such advantages as strength, breathability, naturalness, high values in terms of such indicators as resistance to tearing, breaking and punching, resistance to temperature changes and lack of swelling under the influence of moisture. Also, packaging made from this material elongates when broken, adheres well, and any design can be applied to its surface.
Production technology
To make kraft paper, you need a special machine. Single-layer packaging is done using a flat mesh mechanism. First, the paper pulp, diluted with water to a liquid state and filtered from debris, is fed onto a long mesh that moves. During the process, water leaves the mass through the cells, leaving the fibers to settle in an even layer. Then the presses and spinning rollers begin to work. They remove remaining moisture. Final drying is carried out using a system of fabric-covered cylinders heated from the inside. Calenders smooth out the resulting paper, giving it uniform thickness. The last stage is winding finished products into rolls or cutting into sheets.
The types of different kraft paper differ not only in mechanical characteristics, but also in color, surface texture and roughness, and the type of coating applied on top.
Today, this particular material is the leader among all packaging. After all, it can be used to make not only bags for bulk goods. building materials, but also bags for supermarkets and restaurants, envelopes and other products.
Kraft material is a long-known packaging resource, invented in 1852 in the USA, but only gaining popularity today. It is made from long-fiber cellulose by boiling wood. It is this manufacturing process that makes craft durable, resistant to mechanical damage and suitable for recycling. Also, important criterion Kraft paper is environmentally friendly, and this wrapping material meets all the requirements to the maximum. It doesn't do any harm environment, both during production and after disposal.
Cutting line:)
Advantages of packaging paper:
- Environmentally friendly. The environmental friendliness of craft has been known for a long time. Consists of 100% cellulose and decomposes much faster than similar packaging materials.
- Strength. If you look at the German dictionary, “kraft” can be translated as “strength.” And this is not an accident, it has a density in the range from 35 to 120 g/m2, and washable kraft paper has the highest density. Its main difference is moisture resistance.
- Breathability. This advantage is actively used in the grocery and flower sectors. It helps keep your skin fresh and attractive longer. appearance food products and flower bouquets.
- Ease of printing. The resource has excellent printing properties. Color images and names of products, companies, logos make the packaging an advertising medium.

Dear clients! You will be able to purchase different kinds kraft paper in our small wholesale online store Containers for goods. We are always happy to receive your orders!
Modern and promising direction is the production of craft bags as a business. Its profitability is assessed quite highly, and reviews indicate an ever-growing demand for such products. This will give even a beginner the opportunity to occupy his niche and enjoy growing profits.
The relevance and simple process of their production makes this idea simple and attractive. If you approach the issue with all responsibility, then you can count on the fact that the invested funds will pay off very quickly.
Product Features
First, let's figure out what it is and what craft bags are for. Modern industry offers durable paper packaging that can withstand heavy weight almost any product. Even the name itself comes from the German Kraft (“strength”), which reflects the main property of the material - strength and resistance to mechanical damage.
Thanks to significant advantages, such containers have taken first positions in the field of trade. It is natural and environmentally friendly, helps maintain the quality of products and various materials long period, compact and makes it possible to apply any printed information to the surface.
We also list the main advantages of business on craft bags:
- Ease of organization production process.
- The relevance of the project is maintained at the level of the conservation law surrounding nature.
- There are minimum requirements for the premises.
- Thanks to printing on a paper surface, you can simultaneously engage in advertising activities.
- The versatility of packaging significantly expands the scope of its use and opens up wide opportunities for sales.
Among the disadvantages, only large start-up capital investments and difficulties in finding new clients are noted, especially if the region is marked high level competition.
We prepare documents
The registration procedure is not too complicated. Depending on the desired production volumes or the number of co-founders, a suitable form of activity is selected - LLC or individual entrepreneur. In the first case, it will be possible to sell products to any customers, even corporate companies. In the second, business will be simpler, but some restrictions will remain in terms of future expansion of the company.
The taxation system can be unified, simplified or patent. It is important to indicate the correct OKVED code – 17.21 – Production corrugated paper and cardboard, as well as containers made from these materials. When hiring employees, you will have to register with the Social and Pension Funds.
When preparing the workshop, no special difficulties should arise, since you only need to comply with the requirements for fire safety. To do this, make sure you have an emergency exit, a fire extinguisher, and use fire-resistant materials during repairs. After verification, a representative of the State Property Inspectorate will issue a permit. No additional licenses or certificates are needed to produce kraft bags.
Technological process
To find out what equipment is needed for the production of bags and paper packaging, you should understand what stages the raw materials go through in the process. Let's describe this moment briefly:
- First, blanks are created according to what is supposed to be done. They look like glued tubes made of a certain type of multi-layer paper.
- If necessary, a print with a logo, image, slogan is applied to the surface advertising campaign etc.
- Then, depending on the type of package, it is stitched or glued. This will require different devices. Therefore, initially decide what range of products you will produce. Stitched products are considered more durable and reliable, but the client does not always need this, and they are more expensive.
- When creating special bags with a valve (for closed bags), handles or other elements, perform the corresponding action - install them in in the right places.
- Re-secure the bottom, giving strength to the package.
- The goods are compressed and packaged.
Set parameters (dimensions, volumes, printing, additional elements) you need to, depending on the order received, or decide independently what type of products to provide to customers in finished form. To do this, it is advisable to initially analyze the market and determine what exactly there is an increased demand for in a given region.
Workshop room
Although regulatory authorities do not impose any special requirements for the production of kraft bags, when choosing a building you still need to adhere to some criteria:
- There is enough space for installing purchased devices, and there is also a separate warehouse for storing products.
- It should be clean and dry here so as not to spoil the goods themselves.
- Be sure to check the availability of electricity and other communications, and the network must withstand the load from all connected equipment.
In order to save money, this could be a building located somewhere outside the city or in an industrial part of it. The rent will be low.
Equipment for the production of
As described above technological process should be purchased and all necessary equipment. Let's divide it into two main parts. Basic elements, without which it is impossible to start such a business, are:
- Machine for gluing blanks.
- Special apparatus to form the bottom and re-fasten it.
- If you decide to create stitched packages, then you also need separate equipment for sewing elements together.
Over time, to expand the business, it is advisable to purchase the following items:
- punching machine;
- printing machine for creating various images, inscriptions and effects;
- convenient table for cutting ribbons;
- special mixer for adhesive composition;
- auxiliary mechanisms for lifting and carrying rolls of paper or packaged products;
- filling machine.
With large production volumes, such costs will quickly pay off, but this technique will greatly simplify people's work. Important point, which you should pay special attention to is the cost and power of the equipment.
It can be purchased in our country or abroad, as well as new or used. Since the costs of this item will be too high, you can start with the cheapest options and gradually purchase more powerful and expensive equipment.
Raw material base
Kraft bags are created from the most different materials, depending on what they are then used for. For this use:
- Cardboard.
- Thick paper from recycled materials.
- Luxpack.
- Art libris.
- Special wrapping material.
- Efalin.
- Coated paper, etc.
In each case, special raw materials are needed, which are selected according to technical requirements. If food is supposed to be stored in packaging, then higher standards will have to be observed.
Used for gluing special compounds starch-based, and for stitching - nylon thread. Also don't forget about consumables for creating handles, valves, ink for printing presses, etc. All this is purchased in bulk from suppliers at a minimal cost. To maintain high production rates, it is better to enter into contracts for the constant purchase of products.
Staff
To service all machines and ensure smooth operation of the workshop, 3-4 employees will be needed. But they don’t need any special skills or knowledge. It is enough to be able to handle such devices, and experience in this field of production is desirable.
Accounting functions can be performed by the owner himself or outsourced, that is, to a visiting specialist. Hire a cleaner to keep the premises clean. And to establish sales of products - a qualified manager.
Search for clients
While it is quite easy to create craft bags, finding channels for selling the goods sometimes turns out to be complex process. It’s better to take care of forming a base in advance regular customers. This requires attracting a person with certain knowledge, skills and connections. Despite the high wages such cooperation will be beneficial.
You can sell paper bags to the main consumer groups:
- Retail stores and bakeries - they use packaging to preserve the freshness and taste characteristics of their products.
- Marketing agencies use printed gift bags for promotions and actively use them for advertising purposes.
- Manufacturing enterprises– for packaging various building materials, coal, agricultural products, etc.
- Catering establishments – very often takeaway fast food is packaged in such bags.
- Flower shops - for beautiful design bouquets and gifts.
Every entrepreneur dreams of concluding an agreement to supply their products to regular customers for a long period.
Unfortunately, given the high competition among large manufacturers of kraft packaging, it is very difficult for small businessmen to advance in the market. But if you find new company, which is just beginning its journey and establishes personal contact with the owner, then you can conclude a mutually beneficial cooperation agreement.
Existing risks
It is important for a novice entrepreneur to worry about some points in advance:
- Expensive material for craft bags significantly increases the cost of production and reduces the profit of the business owner. In order to reduce the cost of the production process, it is advisable to contact a supplier of cheap recyclable materials.
- High energy consumption to ensure the operation of all equipment. There is practically no way to avoid this. But it is worth noting that if you purchase machines with high power and low electricity consumption, then having paid once for the device, you will save on monthly utility costs in the future.
- Lack of customers for large quantities of goods. Be proactive in finding customers who might need your products. This and industrial enterprises in the region, agricultural land, companies engaged in the production of building materials or fertilizers, retailers, etc.

Financial part of the business plan
The largest expense item will be the purchase of expensive machines. But if you opt for a minimal set and start your business with used devices, then you will need much less investment. Let us describe the estimated costs based on average prices on the market.
If we calculate in detail the cost of one package, it will be 3.23 rubles. You can sell it for at least 10 rubles. Thus, in a month, with good production capacity, it will be possible to produce about 130,000 products, which in monetary terms will bring a net profit of 868,400 rubles.
Start-up costs pay off already from the first months of work. But this is provided that you organize the sale of goods in the same volume as production. If you develop at a slower speed, then even with minimal costs and small batches of packages sold, within six months all investments will be fully recouped. According to experts, profitability this direction is 30-40%.
Video: production of craft bags.
Kraft paper is known as one of the most environmentally friendly and convenient types packaging material. Translated from German, craft means “durable,” and it is this property that has made the material so widely known. This type of paper was invented in 1852, a little later in 1960 it was improved qualitatively, and today it is a standardized technology that provides precisely specified technical parameters.
Features of the technology, the use of 2 or more layers at the same time, combination with modern materials make it possible to produce various types of kraft paper with unique properties: water resistance, bacteriological resistance, printability, etc. Given its high environmental friendliness, it is gradually replacing toxic vinyl chloride derivatives.
Application in various fields
What is kraft paper used for and in what areas is it used? A semi-finished product is supplied from the manufacturer with a density in the range of 35-120 g/m². In addition to variations in density, paper can differ in strength, color, texture, and number of layers. By combining these parameters, we produce a wide range of products for:
- Design purposes - drawing, decorating gifts and flowers.
- Agriculture - sorting, rearranging vegetables and fruits.
- Trade - food packaging (wrapping paper, grocery bags, garbage bags).
- Food - tetra pack packaging, wrapping paper for butter.
- Industry - production of cardboard based on kraft paper, bags for cement, lime, etc.
- Stationery - envelopes for letters, covers, tags, corrugated cardboard.
- Textile industry - moisture-resistant paper that imitates leather with the possibility of embossing, ironing and other capabilities inherent in natural leather.
- Medical and cosmetology institutions. Kraft paper, what is it in medicine? In terms of significance, an analogy can be drawn with disposable syringes. With its help, sterilized instruments are stored for 50 days. The accuracy of the data is indicated by a color indicator on the top of the envelope.
Advantages and disadvantages
Paper made using the sulphate method differs in its parameters from its conventional counterpart in a number of advantages:
- Environmentally friendly when used with food. None of the types of paper contain volatile substances that interact with food.
- Harmless to nature. Belongs to hazard class 5, i.e. all components are of natural origin; when it gets into the ground, the paper decomposes without causing damage to the latter.
- A wide range of properties according to the criteria: moisture resistance, density, texture, color, increased strength.
- Production of packaging containers of any size, as well as the ability to wrap oversized items.
- Combining paper with polyethylene, bitumen, foil to create protection against moisture and UV rays.
- Empty containers take up little space.
- The lowest cost of all other types of containers (metal, plastic).
The disadvantages of kraft paper relate more to its production:
- Lengthy manufacturing process.
- Low yield of suitable products.
- The need to use prepared in a special way raw materials.
- Expensive equipment at the initial stage.
Health safety
Considering the safety of kraft paper, we highlight 2 components:
- The impact of packaging directly on human health.
- Kraft paper production in relation to the environment.
Since the discovery of polyvinyl chloride compounds, the time has come for plastic. Today its use comes first and has already become global problem. This concerns primarily its toxicity, substances released when heated, and exposure to UV rays. When considering non-toxic materials that could replace plastic at least partially, we can cite only kraft paper as an example. At the molecular level, it consists of long cellulose fibers boiled in an aqueous solution of caustic soda. After the process is completed, all chemical bonds are complete reactions containing no volatile or active elements.
Paper belongs to hazard class 5 waste. It decomposes without residue into chemically neutral elements.
Types (Classification)
Kraft paper is produced by the sulfation method. Its varieties are determined by the raw materials, the catalysts used and the cooking time. Additional properties are given to them at the last stage of production. Kraft paper is supplied in rolls of standard width: 960; 1020; 1030; 1040; 1060; 1090; 1120; 1220; 1230; 1260; 1320 mm, mainly intended for the production of bags and packages. Sulfate cellulose is produced in the following types:
- CS (sulfate cellulose) coniferous unbleached - refers to a high-strength type. Production of paper for: corrugating, bags, cardboard, electrical paper, technical cardboard.
- CS unbleached from mixed breeds - a full-fledged analogue coniferous wood, since the technology makes it possible to obtain a structure, regardless of the type of wood.
- CS bleached coniferous paper - high-quality paper for printing and drawing. Purpose of paper: documents, labels, cartographic, drawing, parchment, sanitary (hygienic), printing.
- CS bleached hardwood- high quality. Purpose: basis for photographic paper, filter paper, decorative base, sanitary, printing, medical.
- CS rehydrolysis - technological with special properties: high-modulus fibers, technical, viscose, cord threads.
Specifications
The main packaging containers made of kraft paper are bags, which differ not only in size, but also in strength characteristics over a wide range. The main indicators are moisture resistance and hygroscopicity. For the manufacture of bags, a type of paper with a density of at least 70 g/m² is used.
Properties
Low density, up to 60 g/m², is used for bags with normal properties and low weight. Kraft paper (density 70; 75; 80; 90 g/m²) can withstand higher loads. It is used as a basis for the production of paper with special properties:
- Microcrepe (klupak) - increased strength, without special properties.
- With polyethylene coating - with moisture-proof properties.
- Bitumenized - for protection from moisture and mechanical influences.
- Lamination - silicone coating - provides high adhesive properties, eliminating the sticking of viscous, sticky and astringent substances.
- Foil kraft paper - for protection from ultraviolet rays.
Choice
Attention! When purchasing paper for critical materials, you need to make sure that it fully complies with GOST and has certificates of conformity.
If we do not consider the choice of paper for design purposes, then for other types there is regulatory documentation that determines the selection of paper for transportation and storage of various materials.
Unbleached thick kraft paper (more than 60 g/m²) is used in the production of bags and sacks for safe storage and transportation. Features of the substance:
- hygroscopicity;
- aggressiveness;
- the humidity of the environment and the duration of stay in it are determined additional properties, which are achieved through the use of bitumen, silicone, and foil.
Unbleached paper of lower density is used mainly for household needs and food packaging.
Bleached paper of low density belongs to the high-quality group and is used for food packaging, as well as for sanitary purposes.
