Heat shrink film is used in the sale and transportation of various products. Its main function is to stabilize, cover and protect the products. Shrink film must have high puncture resistance, good shrinkage and certain shrinkage stress. During the shrinkage process, the film cannot produce holes. Since shrink films are often used outdoors, UV anti-UV agents need to be added.
PE polyethylene, which is a transparent thermoplastic. There are three major categories of PE commonly used, namely: LDPE, HDPE, and LLDPE. The monomers of the three polyethylenes are the same. However, when synthesizing these polyethylenes, the process conditions used are different. Therefore, three different polyethylenes are produced. Polyethylene varieties, the properties of the three materials are quite different.
PE film is a material with very good toughness and is not easily crushed by ordinary plastic crushers. Because the PE film is soft and tough, it is not easy to shred. What's more, the high temperature of the tool at high speed will cause the LDPE to melt and stick to the blade. PE granulation can be directly put into strips into the feeding port of the extruder, and the PE film is dragged into the barrel by the shear force of the screw, heated, melted, extruded and granulated. The first-grade material recycled from PE can still be blown into film and used for non-food and pharmaceutical packaging. It is also widely used in the production of Oxford leather and waterproof cloth. It has a bright future.
Widely used in the integrated packaging of alcohol, cans, mineral water, various beverages, cloth and other products. The product has good flexibility, strong impact resistance, tear resistance, and is not easy to Damage, not afraid of moisture, large shrinkage rate.
POF is a multi-layer extruded environmentally friendly polyolefin heat shrinkable packaging material. The film adopts double-bubble processing technology, using LLDPE as the middle layer material, ternary polypropylene as the inner and outer layer materials, and is produced by three-layer polypropylene extrusion compounding. POF has significant characteristics such as high transparency, high shrinkage, and good heat sealing performance. It has the advantages and strengths of both PP film and PE film, so its product performance far exceeds that of simple PP film and PE film. It is currently the most popular film in the international market. Environmentally friendly heat shrinkable film packaging materials that are widely promoted and used and approved by European and American markets.
OPS (heat shrinkable film) is a new type of skin-friendly packaging material that meets environmental protection requirements. OPS heat shrinkable film has high strength, rigidity, stable shape, and good gloss and transparency. It is easy to process, easy to color, has good printing performance, and has extremely high printing resolution. It is a complete material improvement for trademarks that are constantly pursuing exquisite printing. Due to the high shrinkage rate and strength of OPS film, it can closely fit various containers of different shapes, so it can not only print exquisite patterns, but also meet the use of various novel packaging containers with different shapes. This non-toxic, odorless, grease-resistant film that meets food hygiene standards allows designers to use eye-catching colors to achieve 360° label design, giving full play to creativity and imagination, so that beverages and other commodities can be used on labels. In use, the pattern is more vivid, highlighting the image on the shelf, creating an unexpected container effect.
