Introduction To Food Packaging Materials Packaging

Strapping is made of both PP and PET plastic. Main production process: plastic particles melt pressure----------------cooling and winding----packing – storage strapping with pp by heating, melting, stretching, and cooling to produce the lattice structure of the packaging material, influencing the quality of packaged with the basic parameters are tensile elongation, length, curvature, and so on. Under the same tension and other parameters, the longer the lower cost. Hangzhou Yong-introduction of four of the world's most advanced packing belt production line, process, production of high strength, high quality, eco-friendly 3000 m new strap, pack price unit price per meter costs well below the expected domestic and similar import price, cost 120%,
