Plastic woven bags are polypropylene (PP) as the main raw material, after extrusion, drawing, and then weaving, weaving, bag making. PP is a semi-transparent, semi-crystalline thermoplastic plastic with high strength, good insulation, low water absorption, high heat-to-shape temperature, low density, high crystallinity, and is the main raw material for making woven bags. Modified fillers typically have glass fibers, mineral fillers, thermoplastic rubber, and the like. Plastic woven bags are used in a wide range of applications. At present, plastic woven bags are mainly used for agricultural product packaging, cement bag packaging, food packaging, geotechnical engineering, tourism transportation, and flood control materials. The woven bags mainly include plastic woven bags (non-laminated woven bags), composite plastic woven bags and various woven fabrics.

The production process of plastic woven bags is: woven fabrics are printed, cut, and sewn into woven bags. Depending on the equipment used, it can be cut before printing, or it can be cut after printing. Automatic cutting and sewing can be continuously completed printing, cutting, sewing and other processes, but also can be made into a valve pocket, put the bottom bag, etc., for the flat woven fabric can be made after the seam adhesive bag. The production process of the composite plastic woven bag is to compound or coat the woven cloth, coating compound and paper or film. The obtained tube cloth or sheet cloth, tube cloth can be cut, printed, stitched, made into a common bottom bag, can also be punched, folded, cut, printed, stitched, made of cement bags, the resulting sheet, Can be bonded in the seam, printing, cutting, paste the bottom, made of paste bottom bag. Can also be welded, coiled, made of tarpaulin, geotextile. Flat woven fabrics can be coated or not coated with tarpaulin, geotextiles, etc., and cylinder fabrics can also be coated with or without tarpaulin or tarpaulin or geotextile.
