T-bag is made of polyolefin epoxy resin by metal wire drawing weaving process, then cut into tubular or block plates of different sizes after polyurethane coating, and then sewed into circular or square bags according to the design plan.
The following ton bag manufacturer will introduce to you the usability and sealing of container bags:
Usability of tonnage bags
In the design of plastic woven bags, we should take into account the practical methods and methods of customers'application of plastic woven bags, such as lifting, transportation tools, characteristics of loading raw materials, etc. The other should also consider whether it is a food packaging material and whether it is non-toxic and harmless to the packaged food.
Sealability of tonnage bags
Packaging raw materials are different, sealing requirements are different. For example, granular materials or harmful objects, objects afraid of environmental pollution have strict requirements on sealing characteristics, and raw materials which are very easy to moisture back or mildew also have unique requirements on sealing properties. Therefore, in the design of plastic woven bags, attention should be paid to the hazards to the sealing caused by the sub-film processing technology and sewing technology.
