Paper-plastic composite bags are compounds of plastic and kraft paper. Usually the plastic layer is a plain woven fabric with polypropylene (PP) or polyethylene (PE) as the base material, and the kraft paper layer is made of refined composite special kraft paper, which has the characteristics of high strength, good water resistance and beautiful appearance. It is one of the most popular packaging materials and is widely used in plastic raw materials, cement, feed, chemicals, fertilizers and other industries. Paper-plastic composite bag-composite plastic woven bag is made of plastic woven bag (referred to as cloth) as the base material and is made by casting method (cloth/film composite is two-in-one, cloth/film/paper composite is three-in-one). Mainly used for packaging engineering plastics, rubber raw materials, building materials, food, fertilizers, cement and other powdery or granular solid materials and flexible items. Paper-plastic composite bag: commonly known as: three-in-one bag, is a small bulk container, mainly transported by manpower or forklift. It is easy to transport small bulk powder and granular materials, and has the characteristics of high strength, good waterproofness, beautiful appearance, and convenient loading and unloading. It is one of the most popular and practical general packaging materials. Process description: Refined white kraft paper or yellow kraft paper is used on the outside, and plastic woven cloth is used on the inside. The plastic particles PP are melted by high temperature and high pressure, and the kraft paper and the plastic woven cloth are combined together. An inner film bag can be added. The form of paper-plastic composite bag is equivalent to sewing the bottom and opening the pocket. It has the advantages of good strength, waterproof and moisture-proof.
