Making of PP Woven Sugar Bags

Polypropylene (PP) is the main raw material of
pp woven sugar bags. It is made by extrusion, drawing, weaving and bag making. PP is a translucent, semi-crystalline thermoplastic having the characteristics of the high strength, good insulation, low water absorption, high thermal temperature, low density and high crystallinity, which is the main material for making pp woven sugar bags.  Modified fillers usually include glass fibers, mineral fillers, thermoplastic rubber, etc. Plastic woven bags are widely used. At present, plastic woven bags are mainly used for agricultural products packaging, cement bags packaging, food packaging, geotechnical engineering, tourism transportation, flood materials and so on. There are three main types of woven bags: plastic woven bags (non-laminated woven bags), composite plastic woven bags and various woven fabrics.
