Paper-plastic composite bag is a three-in-one composite paper bag that people often say. It is a small bulk container, mainly used for shipping small bulk powder and granular materials. Compared with general woven bags, paper-plastic composite bags have high strength, good water resistance, high appearance, easy to load and unload, etc. It is a popular and practical general packaging material. Generally speaking, the manufacturing process of paper-plastic composite bags manufacturers is divided into woven bags and composite woven bags. The composite woven bag is divided into plastic film composite and paper-plastic composite according to the packaging material.

The characteristics of paper-plastic composite bags:

1. The appearance characteristics of paper-plastic composite bags:

The outside is refined white kraft paper or yellow kraft paper, and the inside is plastic woven cloth. Plastic particles PP are melted by high temperature and high pressure, and kraft paper and plastic woven cloth are compounded. Inner bag can be added. The form of paper-plastic composite bag is equivalent to an open bottom bag. Has good strength, can be used for waterproof and moisture

2. Application of paper-plastic composite bags:

1 Industrial and agricultural product packaging bags

With the development and application of flexible packaging bags, paper-plastic composite bag manufacturers are widely used in marine transportation packaging and agricultural product packaging. In agricultural product packaging, paper-plastic composite bags have been widely used in aquatic product packaging, poultry feed packaging, and other fields. Covering materials, crop planting shade, windproof, hailproof shed and other materials. Commonly used products: feed compound bags, chemical compound bags, putty powder compound bags, urea compound bags, vegetable mesh bags, fruit mesh bags, etc.

2 food packaging compound bag

Rice, flour and other food packaging are gradually packed in composite bags. Common compound bags include: rice compound bags, flour compound bags, corn compound bags, etc.

3 Cargo transportation

Common are: logistics bags, logistics packaging bags, freight bags, freight packaging bags, etc.

4 Engineering materials

Paper-plastic composites can also be widely used in small water conservancy, power, highway, railway, port, mine construction, military engineering construction and other fields. In these projects, the advantages of using paper-plastic composite bags are filtering, drainage, reinforcement, isolation, impermeability and other functions.

5 Flood control materials

Woven bags are indispensable for flood prevention and disaster relief. Woven bags are also indispensable in the construction of dams, river banks, railways and highways. They are woven bags for flood control information, woven bags for drought resistance and woven bags for flood control.
