PE heat shrinkable film product characteristics introduction

Introduction to the product characteristics of PE shrink film Release time: 2016-08-30 PE shrink film PE polyethylene, it is a transparent thermoplastic. There are three types of PE commonly used, namely: LDPEHDPELLDPE three kinds of polyethylene monomers are the same, but when synthesizing these polyethylenes, the process conditions used are different, therefore, only three different polyethylene varieties are produced. The properties of the three materials are quite different. PE film is a material with very good toughness, and it is not easy to pulverize with ordinary plastic crushers. Because the PE film is soft and tough, it is not easy to be shredded, not to mention the high temperature of the tool at high speed, which will cause the LDPE to melt and adhere to the blade. PE pelletizing can be directly put into the feeding port of the extruder into strips, and the PE film is dragged into the barrel by the shearing force of the screw to heat, melt, and extrude pellets. PE recycled first-grade materials can still be blown film, used for non-food and pharmaceutical packaging, and also widely used in the production of Oxford leather and tarpaulin, with a bright future. PE heat shrinkable film is widely used in the whole assembly packaging of wine, cans, mineral water, various beverages, cloth and other products. The product has good flexibility, impact resistance and tear resistance, and is not easy to break and fear. Moisture and high shrinkage rate. PVC shrink film, with additional ingredients to enhance its heat resistance, toughness, ductility, etc. The top layer of this surface film is lacquer, the main component in the middle is polyvinyl chloride, and the bottom layer is back-coated adhesive. It is a kind of synthetic material that is well-loved, popular and widely used in the world today. Among the materials that can produce three-dimensional surface films, PVC is the most suitable material. Due to the unique properties of PVC (rain-proof, fire-resistant, anti-static, easy to shape) and low-input high-output characteristics of PVC, it is widely used in the building materials industry and packaging industry. Therefore, PVC film has high transparency, good gloss, and shrinkage. Features of high rate. Previous: New Wrapsmart pre-stretched stretch film
