What equipment is needed to open a bag processing plant

by admin

Please give me some advice. Thanks, little brother

1. Packaging bag processing requires two kinds of printing equipment, including ordinary gravure printing machine and relief printing machine. The printing equipment of food packaging bags mostly adopts gravure high-speed printing machine. The printing equipment has the characteristics of high precision, fast printing speed and stable printing. It is a high-end printing equipment in China

2. Packaging bag processing requires slitting machine, also known as slitting machine, which is a necessary equipment for automatic film rolling of food. The maximum slitting speed of computer automatic slitting machine can reach 300m per minute, which is a leading level in the slitting machine equipment of the same industry

a good slitter is equipped with a good master to cut the roll film with accurate specification and high flatness. It can be used stably on the automatic packaging machine without film sticking, film breaking and other phenomena

3. Bag making machine is the equipment used in the last process of food packaging bag production process. Different bag making machines are used according to different bag shapes. For example, for the production of three side sealed vacuum bags, the three side sealed heavy pressing bag making machine shall be adopted. For self-supporting bags and zipper bags, the zipper bag making machine shall be adopted. The middle sealing bag making machine is used to make center bag and tea bag

4. Dry compounding machine is a machine that sticks different plastic films together to form composite films through dry compounding process. Dry compounding process is to fully dry the solvent in the glue solution by heating and exhaust after gluing, and then compound it in a “dry” condition. In view of the dry compounding opportunity to compound different plastic films, aluminum foil and even paper, the requirements for the dry compounding machine are higher

5. After the liquid plastic is sprayed out, the plastic body is blown and attached to the mold cavity of a certain shape by using the wind force blown out by the machine, so as to make the product. This machine is called blow molding machine

extended data

woven bag is a kind of plastic for packaging. Its raw materials are generally polyethylene, polypropylene and other chemical plastic raw materials; Plastic woven bag is made of polypropylene resin as the main raw material, extruded and stretched into flat silk, and then woven and made into bag

polyethylene is mainly produced abroad & nbsp; (PE), the domestic production is mainly polypropylene (PP). Polyethylene is a thermoplastic resin prepared by polymerization of ethylene. In industry, it also includes ethylene and small amounts α- Copolymers of olefins

polyethylene is odorless, non-toxic, feels like wax, has excellent low temperature resistance (the minimum service temperature can reach – 70 ~ – 100 ℃), good chemical stability, can resist the erosion of most acids and bases (not resistant to acids with oxidation properties), is insoluble in general solvents at room temperature, has small water absorption and excellent electrical insulation performance; However, polyethylene is very sensitive to environmental stress (chemical and mechanical action) and has poor heat aging resistance

the properties of polyethylene vary from variety to variety, mainly depending on molecular structure and density. Products with different densities (0.91 ~ 0.96 g /cm3) can be obtained by different production methods. Polyethylene can be processed by the molding method of general thermoplastic

is widely used. It is mainly used to manufacture films, containers, pipes, monofilaments, wires and cables, daily necessities, etc., and can be used as high-frequency insulating materials for TV, radar, etc

1. If you want to open an express bag processing plant, you need two kinds of equipment: a blow molding machine (making bags) and a printing rotating machine (printing words and images on the surface of bags)

2. After the liquid plastic is sprayed out, the plastic body is blown and attached to the mold cavity of a certain shape by using the wind force blown out by the machine, so as to make the product. This machine is called blow molding machine

3. If we start with plastic particles, the price of raw materials is now about 9000 yuan per ton. We also need three machines: film blowing machine, bag making machine and punching machine. Machines are large and small, fully automatic, semi-automatic, 30000 or 40000, and 56000. It depends on personal needs. The detailed equipment is shown in the figure below:

extended data

1. Packaging of agricultural products, and then replace paper cement packaging bags

(1) at present, due to product resources and price problems, 6 billion woven bags are used for cement packaging in China every year, accounting for more than 85% of bulk cement packaging With the development and application of flexible coke bagging, plastic woven container bagging is widely used in marine, transportation and packaging of industrial and agricultural products

(2) in the packaging of agricultural products, plastic woven bags have been widely used in aquatic products packaging, poultry feed packaging, covering materials for farms, sunshade, wind and hail shelter for crop planting Common products: feed woven bags, chemical woven bags, putty powder woven bags, urea woven bags, vegetable mesh bags, fruit mesh bags, etc

2. Food packaging

in recent years, woven bags have been gradually used for food packaging such as rice and flour Common woven bags are: rice woven bags, flour woven bags, corn woven bags and other woven bags

3. Geotechnical engineering

since the development of Geotextiles in the 1980s, the application field of plastic woven fabrics has been widened and widely used in small water conservancy, electric power, highway, railway, harbor, mine construction and military engineering construction In these projects, geosynthetics have the functions of filtration, drainage, reinforcement, isolation and anti-seepage. Plastic geotextile is one of the synthetic geosynthetics

4. Tourism transportation

temporary tents, umbrellas, various travel bags and travel bags in tourism are all used as plastic woven fabrics. Various tarpaulins are widely used as covering materials for transportation and storage, replacing the cotton tarpaulins that are easy to mildew and bulky. Fences and mesh covers in construction are also widely used as plastic woven fabrics. Common are: logistics bag, logistics packaging bag, freight bag, freight packaging bag, etc

5. Daily necessities

there are plastic woven products everywhere in shops, warehouses and homes The backing material of chemical fiber carpet is also replaced by plastic woven fabric Such as shopping bags, supermarket shopping bags, supermarket environmental protection shopping bags; Freight woven bag for logistics transportation, logistics woven bag

6. Flood fighting materials

woven bags are indispensable for flood fighting and disaster relief Woven bags are also indispensable in the construction of dams, river banks, railways and roads They are flood control woven bags, drought prevention woven bags and flood control woven bags

7. Special woven bags

due to special factors, some industries need to use woven bags that are not normally used, such as carbon black bags. The biggest feature of carbon black bag: sunscreen. That is, carbon black woven bags have a strong sunscreen ability than ordinary woven bags. Ordinary woven bags can’t stand the long-term exposure of the sun. There are also anti UV woven bags: with anti UV function, anti-aging function, etc

Hello, I don’t know what kind of bags you want to make
there are compound food packaging bags, vest shopping bags, PE continuous roll packaging bags, PE heavy bags, woven bags, etc

there are many kinds of packaging materials. It depends on what kind of paper packaging, flexible packaging and non-woven packaging you want to open

composite flexible packaging includes Gravure plastic printing machine, compound machine slitting machine sealing, main machinery of bag making machine, air compressor in curing room, etc.
there is no need for too many machinery for non-woven bag processing, that is, sewing machine and printing machine can start

I have the equipment you need, which is 70-80% new
