Analysis of the current situation of China's PE strapping plastic packaging industry

China is a major packaging manufacturing and consumption country in the world. Plastic packaging accounts for more than 30% of the total output value of the packaging industry, and has become a new force in the packaging industry, playing an irreplaceable role in various fields of food, beverage, daily necessities, industrial and agricultural production. At present, plastic products produced in China are mainly plastic films (including agricultural films), plastic wires and woven products, plastic pipes and daily-use plastic products. If divided by application, packaging products are one of the most important plastic application fields. PE, PP and pet are the three most commonly used plastic packaging materials

in the PE plastic packaging industry, non-polar and polar ethylene copolymers and metallocene ethylene are the two hot spots in the development of European and American countries. Ethylene copolymer can improve the tensile and coextrusion properties of plastic film, improve transparency, enhance stability, improve molecular weight distribution and extrusion rheological properties

vldpe (ultra-low density polyethylene) is taking the place of LLDPE, PP, EVA and PVC in extrusion. Today, we just briefly introduce the content of the transformation. In injection molding and blow molding process, it will occupy the flexible packaging market such as medicine and cosmetics, and will impact the field of food packaging. PA bags are produced by mixing linear vinyl copolymer with ethylene vinyl acetate copolymer, which can obtain the tensile strength, yield strength, specified non proportional elongation strength, elastic modulus and other performance indicators of the tested materials. They are also used in food packaging such as ice cream and milk fat

Metallocene polyolefins are polymers prepared by olefin polymerization with metallocene coordinated vanadium as the material base compound as the catalyst. Maojin we can design different fixtures according to different samples and experimental methods. Polyethylene has many advantages, such as good gloss, high melt strength and film stability. It is suitable for the field of food packaging and has received widespread attention from industry insiders. It is generally believed that metallocene plastics will directly impact PP, MDPE, LLDPE, elastomer and other plastic markets. At present, the demand for PE in the world market is 80million tons, and most of the increase in the future is expected to be metallocene polyethylene
