Paper plastic composite bag is a new type of packaging bag. Because of its high strength, aging resistance, high temperature resistance and other characteristics, it is widely used in the market, and can be used for packaging food, building materials, chemicals and other aspects. What are the advantages of paper plastic composite bags? Here is a detailed introduction. Paper plastic composite bag has obvious moistureproof effect. Because it is made of PVA film, it has a certain fluidity and film-forming property. The inner layer of the bag has a film, which plays a role in bonding and moistureproof. In addition, there are invisible pores on the surface, which can effectively prevent water molecules from entering the bag and prevent the contents from being damp.
In addition, the production of paper plastic composite bags is controlled by warp and weft yarns. Because vinylon water-soluble yarn has the characteristics of high temperature resistance, and the breaking force of single yarn remains unchanged, the bags compounded with it also have certain characteristics of high temperature resistance.
Because the single yarn breaking force insists on the invariable characteristic of using vegetable substances, it is not easy to age. In addition, it is opaque. The paper inside the bag can avoid ultraviolet radiation, and it is not easy to age after a long time of use, playing a certain anti-aging role. The outer surface of the inner layer of the bag can form a lot of mesh structures, which can greatly improve the internal stress of the bag and make the strength of the packaging bag higher. In the process of pressurizing load, the bag surface forms a triangular network, which increases the friction coefficient of the bag surface. Because it is treated by resin acetal, the inner and outer paper can be recycled after soaking, so it will not pollute the environment.
