1:  PE heat shrink film is widely used in wine, cans, mineral water, all kinds of drinks, cloth and other products of the whole set packaging, the product is flexible and has good impact resistance, tear resistance, not easy to damage, not afraid of moisture, high shrinkage rate;  

2:  PVC heat shrink film has the characteristics of high transparency, good gloss and high shrinkage rate;  

3:  POF heat shrink film is characterized by high surface gloss, good toughness, large tear strength, uniform heat shrink and is suitable for automatic high-speed packaging, etc., which is the replacement of traditional PVC heat shrinkage film [1].  POF means heat shrink film. POF full name multilayer co-extruded polyolefin heat-shrinkable film. It is made of linear low-density polyethylene as the middle layer (LLDPE) and co-polypropylene (PP) as the inner and outer layers through three extruders plasticizing extrusion and then processed by special technology such as mold head forming and film bubble blowing.

4:  OPS shrink film (oriented polystyrene) heat shrink film is a new type of OPS shrink film packaging material that meets the requirements of environmental protection. OPS heat shrink film has high strength, large rigidity, stable shape, and good glossiness and transparency.  Convenient processing, easy coloring, good printing performance, high printing resolution, for the unceasing pursuit of exquisite printing trademark, is material progress.  Since the OPS film high shrinkage rate and its strength can with different shapes of container fit tightly, it can not only print out the exquisite design, also can meet the use of a variety of different shapes of novel packaging containers, non-toxic tasteless, resistant to oil, up to the standard of food hygiene film allows designers to use the color with striking,  Realize 360° label design, give full play to creativity and imagination, so that drinks and other goods in the label used more vivid pattern, highlighted the image on the shelf, produces an unexpected container effect.  

5:  PET heat shrink polyester film characteristics: it is stable at room temperature, heating (above the glass temperature) contraction, and is in one direction of more than 70% of the heat contraction. The advantages of heat shrink polyester film packaging are ① body transparent, reflect the image of goods.  ② tight packaging product, good anti-dispersion.  ③ Rainproof, moisture proof, mildew proof.  ④ No recovery, a certain anti-counterfeiting function. Heat shrink polyester is often used in convenience food, beverage market, electronic appliances, metal products, the especially shrinkable label is its main application field. Since the rapid development of PET drink bottles, such as Coke, Sprite, all kinds of fruit juice and other drink bottles need PET heat shrink film to do heat sealing label, they belong to polyester class, it is environmentally friendly materials, easy to recycle and reuse.  

Heat shrink polyester film in addition to being used for shrinkable labels, in recent years also began to be used in the outer packaging of daily goods.  Since it can not only protect the packaging goods to avoid impact, rain, moisture, rust, but also make the product with exquisite printing packaging to win users, at the same time, it can well show the excellent image of the manufacturer.  At present, more and more packaging manufacturers use printed shrink film to replace the traditional transparent film.  Because printing shrinkage film can improve the appearance of the product grade, is conducive to product advertising, can make the trademark brand in the hearts of consumers have a deep impression.
