Today we will talk about FIBC Bags one of the Conductive FIBC Bags, and what is the difference between it and ordinary FIBC Bags?

Conductive FIBC Bags and Common FIBC Bags distinguish from the following：

1, FIBC Bags look at the color of its plastic. Generally, the color of the new material is relatively bright, if the feeling of color is too bad plastic, it is possible that the material is poor. Conductive FIBC Bags the lighter the color, the use of a wider range such as White, both adjustable into a variety of other colors, but also go back to the White product, the same price is high.

2, look at the brightness, of course, these can be removed for transparent material, generally, look at the table bright, good color, the performance of the material is better, different sources of waste plastic bags caused by the use of different levels of waste plastic bags prices are different.

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.

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.

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.
