OPS/PE/PVC/POF/PET shrink film


1) PE heat shrinkable film is widely used in the package of wine, cans, mineral water, beverages, cloth and other products. The product has good flexibility, anti-impact, anti-tear, not easy to break, not afraid of damp, shrinkage rate is large.


2) The characteristics of PET thermal shrinkable polyester film: it is stable at room temperature, when heated (glass transition temperature above) shrinkage, and in one direction occurs more than 70% of the thermal shrinkage. The advantages of heat shrinkable polyester film packaging are: (1) body transparent, reflecting the image of the product. 2. Tight packing, good dispersing resistance. Rainproof, moisture-proof and mildew proof. (4) no recovery, there is a certain anti-counterfeiting function. Heat shrinkable polyester film is often used in convenience food, beverage market, electronic and electrical appliances, metal products, especially shrinkable label is the most important application field. Because with the rapid development of PET beverage bottles, such as cola, Sprite, all kinds of fruit juice and other beverage bottles need PET heat shrinkable film to be matched with them as heat sealing label. They are both polyester, environmentally friendly materials, easy to recycle.


3) POF has the characteristics of high gloss, good toughness, high tear resistance, uniform heat shrinkage and suitable for full automatic high-speed packaging. It is a replacement of traditional PVC heat shrinkage film. POF is the meaning of heat shrinkable film, POF is called multi-layer co-extruded polyolefin heat shrinkable film, it is a linear low-density polyethylene as the intermediate layer (LLDPE), copolypropylene (pp) as the inner and outer layer, through three extruders plasticized extrusion, and then mold molding, bubble bulging and other special processes processed.


4) OPS shrinkable film (oriented polystyrene) thermal shrinkable film is a new kind of packaging material which meets the requirements of environmental protection. OPS thermal shrinkable film has high strength, high rigidity, stable shape, good gloss and transparency.  Easy processing, easy coloring, good printing performance, has a high printing resolution, for the constant pursuit of exquisite printing trademarks, is entirely a material progress. Because of its high shrinkage and strength, the OPS film can be tightly bonded to various containers of different shapes, so it can not only print exquisite patterns, but also meet the use of novel packaging containers with different shapes. This non-toxic, odorless, oil-resistant film can be used by designers to meet food hygiene standards. Attractive color, achieve 360 degrees of label design, give full play to creativity and imagination, so that drinks and other goods in the use of labels more vivid patterns, highlight the image on the shelves, resulting in an unexpected container effect.


5) PVC film has the characteristics of high transparency, good gloss and high shrinkage.


In addition to being used as shrinkage labels, heat-shrinkable polyester films have also been used in the packaging of daily commodities in recent years. Because it can not only protect the packaging from being shocked, rain, moisture, rust, but also enable the product to win customers with exquisite printed packaging, and it can well show the good image of the manufacturer. At present, more and more packaging manufacturers use printed shrink film instead of traditional transparent film. Because the printing shrinkage film can improve the appearance of the product grade, is conducive to product advertising, can make trademark brand in the hearts of consumers have a deep impression
