纸塑复合袋是盛装化肥、水泥、粮食等粉状、粒状产品的理想包装容器，其盛装范围一般在20kg～50kg，具有便于装卸、堆码、搬运和储存的特点。上述包装容器按装载质量范围均分为A型和B型，A型为＜30kg，B型为30～50kg。塑料编织袋、复合塑料编织袋是以聚丙烯或聚乙烯树脂为主原料，加入少量辅料，混匀后经挤出机熔融挤出塑料薄膜切割成丝，在低于树脂熔融温度下进行拉伸，通过分子定向与热定型制成高强度、低延伸率的扁丝，再经卷绕、织布、(复膜)、载剪、缝合制成塑料编织袋、复合塑料编织袋，纸塑复合袋是用适当克重的纸袋纸经复膜、粘合、边用纸条包缝成袋。
Paper plastic composite bag is an ideal packaging container for chemical fertilizer, cement, grain and other powdery and granular products. Its loading range is generally 20kg ~ 50kg, which is convenient for loading, unloading, stacking, handling and storage. The above packaging containers are divided into type A and type B according to the loading mass range. Type A is less than 30kg, and type B is 30-50kg. Plastic woven bags and composite plastic woven bags are made of polypropylene or polyethylene resin as the main raw material, a small amount of auxiliary materials are added, and then the plastic film is melted and extruded by the extruder to cut into wires, which are stretched at a temperature lower than the melting temperature of the resin, and then the flat wires with high strength and low elongation are made by molecular orientation and heat setting, and then the plastic is made by winding, weaving, (laminating), carrying shear and sewing Woven bags, composite plastic woven bags, paper plastic composite bags are made of paper bags with appropriate weight by laminating, bonding and wrapping with paper strips.
