塑料编织袋按主要材料构成为聚丙烯袋、聚乙烯袋；按缝制方法分为缝底袋、缝边底袋。目前广泛应用于肥料、化工产品等物品的一种包装材料。其主要生产工艺是利用塑料原料经挤出薄膜、切割、单向拉伸为扁丝，经过经纬编织得到产品，一般称为编织袋。塑料扁丝，塑编行业简称：扁丝，也有称为切割纤维，它是生产塑料编织物的基本材料，扁丝由特定品种的聚丙烯，聚乙烯树脂经熔融挤出成膜，然后，纵向分切成条，诸条同时加热牵伸取向后定型，最终卷绕成扁丝纱锭，供织造编织物。
Plastic woven bags are composed of polypropylene bags and polyethylene bags according to the main materials; according to the sewing method, they are divided into seamed bottom bags and seamed bottom bags. It is widely used as a packaging material for fertilizers and chemical products. The main production process is to use plastic raw materials to extrude film, cut, and uniaxially stretch into flat filaments, and then weave them through warp and weft to obtain products, generally called woven bags. Plastic flat wire, abbreviated in the plastic braiding industry: flat wire, also known as cutting fiber, it is the basic material for the production of plastic woven fabrics. The flat wire is made of a specific variety of polypropylene and polyethylene resin by melting and extruding into a film, and then longitudinally It is cut into strips, and the strips are heated at the same time for drafting orientation and then shaped, and finally wound into flat yarn spindles for weaving braids.
