Shrink Film
The shrink film has high puncture resistance, good shrinkage and certain shrinkage stress. Mainly used in the sales and transportation process of various products to stabilize, cover and protect products. Shrink packaging not only looks beautiful, but also plays a role in moisture-proof, dust-proof, loose-proof, anti-theft and collection.
Shrink film is used in the sales and shipping process of various products. Its main function is to stabilize, cover and protect the product. The shrink film must have high puncture resistance, good shrinkage and certain shrinkage stress. During the shrinking process, the film cannot create holes. Since shrink films are often used outdoors, UV anti-ultraviolet agents need to be added. Including OPS/PE/PVC/POF/PET shrink film 1) PE heat shrinkable film is widely used in the whole package packaging of wine, cans, mineral water, various beverages, cloth and other products. The product has good flexibility, strong impact resistance and tear resistance, and is not easy to break. , not afraid of the tide, the shrinkage rate is large; 2) PVC film [1] has the characteristics of high transparency, good gloss and high shrinkage; 3) POF has the characteristics of high surface gloss, good toughness, high tear resistance, uniform heat shrinkage and suitable for automatic high-speed packaging. It is a replacement product of traditional PVC heat shrinkable film. POF is the meaning of heat shrinkable film. POF stands for multi-layer co-extruded polyolefin heat shrinkable film. It uses linear low density polyethylene as the middle layer (LLDPE) and copolymerized polypropylene (pp) as the inner and outer layers. It is extruded out of the machine, plasticized and extruded, and then processed by special processes such as die forming and film bubble inflation. 4) OPS shrinkable film (oriented polystyrene) heat shrinkable film is a new type of packaging material with ops heat shrinkable film body that meets environmental protection requirements. OPS heat shrinkable film has high strength, high rigidity, stable shape and good gloss. degree and transparency. It is easy to process, easy to color, has good printing performance, and has a very high printing resolution. For trademarks that constantly pursue exquisite printing, it is a complete improvement in material. Due to the high shrinkage rate and strength of OPS film, it can be closely attached to containers of various 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, food-hygienic film allows designers to use eye-catching colors to achieve 360° label designs, giving full play to creativity and imagination, so that beverages and other products can be used on labels. In-use patterns are more vivid, highlighting the image on the shelf, creating an unexpected container effect. 5) Characteristics of PET heat-shrinkable polyester film: it is stable at room temperature, shrinks when heated (above the glass transition temperature), and heat shrinks more than 70% in one direction. The advantages of heat shrinkable polyester film packaging are: 1. The body is transparent and reflects the image of the product. ② The packaging is tightly bundled, and the anti-scattering property is good. ③ Rainproof, moistureproof and mildew proof. ④No recovery, there is a certain anti-counterfeiting function. Heat shrinkable polyester film is often used in convenience food, beverage market, electronic appliances, metal products, especially shrink label is its main application field. Because with the rapid development of PET beverage bottles, beverage bottles such as Coke, Sprite, and various juices need PET heat shrinkable films to be matched with them as heat-sealing labels. They all belong to polyester, which are environmentally friendly materials and are easy to recycle. use. In addition to being used as shrink labels, heat shrinkable polyester films are now also used on the outer packaging of daily commodities. Because it can not only protect the packaged items from impact, rain, moisture and rust, but also make the product win users with beautifully printed outer packaging, and at the same time it can well show the good image of the manufacturer. Today, more and more packaging manufacturers use printed shrink film to replace the traditional transparent film. Because the printing shrink film can improve the appearance of the product, it is conducive to the advertising of the product, and can make the trademark brand have a deep impression in the minds of consumers.
