With the requirements of environmental protection in the world, paper plastic packaging bags slowly into the right track, then what are the advantages of paper plastic packaging bags? Paper plastic packaging bag is a kind of high strength, anti aging, high temperature resistance, moistureproof, breathable, non-toxic and harmless new packaging bag. Widely used in packaged food, fresh frozen food, starch, casein, feed, building materials, chemicals, minerals and other industries of the commodity bag.
It has the following six advantages
A, moistureproof
Because PVA has excellent fluidity and film formation, in the process of pressure compound will form a layer of film in the inner layer of paper-plastic packaging bag, play the role of composite adhesion and moisture-proof. The other surface has many invisible holes, which can effectively prevent the water molecules outside the paper plastic bag from entering the bag.
Two, high temperature resistance
The strength of paper-plastic bag is mainly controlled by warp and weft. The water-soluble pYLON yarn has the characteristic of constant breaking force at 180 ℃. The paper's ignition point is 183 degrees, so the composite bag also has the characteristics of high temperature resistance.
Three, anti-aging
Because paper is not easy to aging plant material, with the characteristics of opaque, paper plastic bag inside and outside the paper under ultraviolet radiation can effectively protect the paper is not aging, so that the bag together with the characteristics of anti-aging.
Four, high intensity
The strength of paper plastic bag is mainly controlled by the warp and weft direction. Due to the counterclockwise rotation of the weft tray, the outer surface of the inner paper will form many triangular mesh structures, greatly increasing the internal stress of the packaging bag, so that the packaging bag has a high strength.
Five, stacking bags that are not slippery
Because in the process of pressure compound, the outer surface of the paper plastic bag formed a lot of triangular mesh structure, increase the friction coefficient of the outer surface of the bag, so that the bag will not slip in the process of stacking (up to 40 degrees).

Protect the environment
Since pVA water-soluble yarn is not treated by resin acetal, it can be dissolved in 80 hot water to form glue. After soaking, the inner and outer layers of the paper can be recycled to make recycled paper without polluting the environment.
Paper-plastic bag, also known as three in one composite paper bag, is a small bulk container, mainly by manpower or forklift unified transport. Easy to transport small amounts of bulk powder and granular materials. It has the characteristics of high strength, good waterproof, high appearance, convenient loading and unloading, is popular and practical commonly used packaging materials.
Paper plastic bags are mainly used for packing building materials, mortar bags, putty powder, food, chemical raw materials and other powdery or granular fixed materials and flexible items. In recent years, they have also been widely used in express packaging in online sales, three-dimensional wall stickers, car seats, seat covers and other fields.
