Bags for weaving, also known as snake skin bags, are a type of plastic used for packaging. Their raw materials are generally various chemical plastic materials, such as polyethylene and polypropylene.
Define
The weaving density refers to the number of warp and weft threads within a 100mm x 100mm woven fabric. According to the national standard GB/T8946-1998, "flatten the bag and mark two 100mm x 100mm squares at the upper and lower diagonals of the bag. The squares should be 100mm away from the bag's edge. Estimate the number of warp and weft threads in the squares, take the average, and count as one when there are less than one thread after the end point." The national standard specifies the weaving density and also the tolerance of density. The weaving density mainly depends on the packaging product and is determined by the user.
Raw Materials
Explanation of Plastic Braiding: Plastic woven bags are primarily made from polypropylene (PP) as the main raw material. They are extruded and stretched into flat yarns, which are then woven, braided, and finally bagged.
