How is woven plastic bags made?

First of all, it should be distinguished that the production process of woven plastic bags, which are several in one, two in one and three in one, is to compound or coat the woven fabric, coat the compound material and paper or film. The obtained barrel cloth or sheet cloth can be cut, printed, sewed and made into ordinary sewing bottom bags. It can also be punched, folded, cut, printed and sewed into cement bags. The sheet cloth obtained can be sewed, bonded, printed, cut, pasted and made into paste bottom bags. It can also be welded, rolled and made into tarpaulins and geotextiles.

Compound bagging is the key technology.

The principle of coating is that the resin is coated on the base material braided fabric in the melting state. The melted resin is coated on the braided fabric and cooled immediately to form a two-in-one braided fabric. If the melt resin film is sandwiched between the woven fabric and paper or plastic film, and then cooled to get three-in-one braided fabric coating, the flat fabric can be coated on one side to get sheets, and the cylinder cloth can be coated on both sides to get coated cylinder cloth. The coated woven fabrics can be printed, cut and sewed into various bags, and the wide coated fabrics can also be rolled out as tents.

High-temperature tons of bag handling should pay attention to what

　　Now we use the high-temperature tons of bags is a lot, in the use of great help to us. But I believe that many of us on the high-temperature tons of bags do not know much, just some of the surface of understanding, not deep enough. In the use of time need to pay attention to some problems, and to pay attention to. So the use of high-temperature tons of bags need to pay attention to what? Now we have to introduce high-temperature tons of bag loading and unloading is what should be noted, We will make a detailed introduction for you in the following article, suggest that you come with us to understand.

　　1, in the lifting operation, do not stand in the container below.

　　2, please hang hanging hook hanging in the middle of the Sling or Sling, do not oblique hanging, single-sided hanging or cable-hanging container bag.

　　3, do not work with other items friction, hook or collision container bag.

　　4, do not pull the sling to the outside reverse.

　　5, container bag when using the forklift operation, please do not make contact with the fork or tie to the bag body, to prevent breaking the container bag.

　　6, in the workshop handling, try to use the tray, avoid hanging hook with container bag, side shaking side handling.

　　The above six points to introduce the high-temperature tons of bag handling should pay attention to some of the problems. For the handling of high-temperature tons of bags most people are still relatively strange, but if there is a need to use, then we still need some detailed understanding, one is to be able to help you choose, two is to learn to use, pay attention to some problems in use, the correct use. If you want to understand the price of high-temperature ton bags, then you can contact us for communication, we welcome everyone to consult.

How much is a ton bag?

How much is a ton bag?

The material of ton bags is generally made of PP polypropylene, which is mainly divided into brand-new PP materials, PP recycling materials, powder materials, etc.

The price of ton bags is generally calculated by the standard weight of ton bags themselves; according to the size specifications of designed ton bags, the corresponding weight ratio is calculated; and then the price of each gram is calculated.

So in order to know more than one ton of bags, it depends on the material, weight, and specifications.

Is TYPE A 1-ton jumbo bag?

Type A: Commonly used container bags, in which U-shaped bags and cubic bags, tapered bags and leak-proof bags are the largest bags we produce.

Type B: Anti-static bag with inner coating film, the bag body has a breakdown voltage of no more than 4 kV. This container can be used in places with flammable dust, but it cannot be used in hazardous areas.

Type C: Hebei Wanhefeng Factory produces its own conductive flat wire, weaves C-type conductive base fabric and produces a C-type conductive bag and conductive inner bag. This bag is suitable for filling and discharging in the environment of flammable dust or explosive gas and has the correct grounding, which is not dangerous.

Type D: This bag is suitable for a variety of products that require conductive bag packaging, which is characterized by the fact that no grounding is required. A static dissipative bag with antistatic coating and corona discharge effect developed and produced by Hebei Wanhefeng Factory.

The difference between dangerous metal copper packaging and Container bag packaging

There is a special conductive Container bag for dangerous goods packaging. Type C Conductive Bags are designed for sensitive, flammable and explosive environments, including combustible hydrocarbon vapor environments.

This type of Container bag is made of a conductive cloth or a woven cloth coated with a conductive/antistatic coating. The conductive cloth is a woven fabric of interwoven conductive fibers/flat wires. The C-type design must meet the electrostatic ignition hazard standard. The most fundamental thing is that the conductive properties of all the components of the Container bag are connected and grounded.

If the Container bag is not grounded during filling or unloading, it will be possible to generate a high-energy spark discharge on the surface of the bag sufficient to ignite flammable or explosive dust or solvent vapor. Therefore, the grounding membrane must be designed on the Container bag. Of course, the conductive wire of the sling also acts as a grounding force when the Container bag is suspended during use.

Nowadays, many companies choose Container bag transportation, which is reusable, recyclable, low weight, easy to mechanize loading and unloading operation and easy to transport and transport.
