Application of Paper Plastic Composite Bags in Agriculture

The three in one paper plastic composite bag is composed of plastic and kraft paper. The plastic layer of the paper plastic composite bag is usually made of PP silk woven fabric with PP polypropylene (PP) as the substrate, while the kraft paper is made of refined composite special kraft paper. The two are bonded by melting plastic heat laminating film, and the kraft paper film is formed by bag making and then processed and sewn into a three in one paper plastic composite bag. Plastic composite bags are generally made of BOPP and co extruded film, BOPP and PET composite, and so on. Composite bags generally come in two or three layers. Composite bags are usually printed in color between two types of films, and when the edges of the torn composite bag are welded, two or three layers will appear. This is called a composite bag. Ordinary bags only have one layer of surface printing, which can be scraped off with a small knife, while composite bags cannot be scraped off. Use plant ash to prevent insects. Mix an appropriate amount of dry plant ash with grain, then put it into a container, cover it, and remove the plant ash before consumption. This method does not require sealed containers. Therefore, cylinders, paper plastic composite bags, and woven bags are all suitable. In addition, dry grains can be placed in containers, about 5-8 centimeters away from the mouth; Place 3 layers of newspaper on the grain surface (do not use plastic film); Spread 3-5 centimeters of dry wood ash on the paper, cover and seal tightly. This method is simple and effective, suitable for storing raw grains.
