Heat Shrink Wrap, a film that shrinks in response to heat, thus tightly covering the product. The main materials used are various thermoplastic films. The main materials used are various thermoplastic films. Initially mainly PVC Shrink Wrap, with the continuous development of market demand, PVC Shrink Wrap gradually reduced, and a variety of POF Shrink Wrap,PET Shrink Wrap,PP Shrink Wrap,PE Shrink Wrap and other multi-layer co-extruded heat shrink wrap has developed rapidly, becoming the mainstream of the market.
PVC Shrink Wrap
It has the characteristics of high transparency, good gloss, high shrinkage rate, it will become brittle after heat contraction, and it is very easy to damage.
POF Shrink Wrap
High surface gloss, good toughness, tear strength, uniform heat shrinkage and suitable for automatic high-speed packaging, is the replacement of traditional PVC heat shrink film products.
PET Shrink Wrap
PET shrinkable film is a new kind of shrinkable packaging material. Because it is easy to recycle, non-toxic, tasteless, good mechanical properties, especially in line with environmental protection and other characteristics, in developed countries polyester (PET) has become an ideal substitute for PVC heat shrinkable film.
PE Shrink Wrap
Widely used in wine, cans, mineral water, all kinds of beverages, cloth and other products of the whole package, the product has good flexibility, impact resistance, tear resistance, not easy to damage, not afraid of moisture, shrinkage rate is large.
The principle of heat shrink film can be divided into two parts: heat shrinkage and plastic properties. Thermal shrinkage refers to when heated to a certain temperature at degrees Celsius, the heat shrink film will shrink, achieving a shrinkage effect and a tight sealing. And plastic refers to the ability of the plastic material of the heat shrink film to deformation occurs while heating, so it can adhere tightly to the surface of the item.
The application range of heat shrink film is very wide, such as in fields such as food, medicine, stationery, home, etc. Especially food in the product industry, heat shrink film can extend the shelf life, improve product quality, and also be used for product decoration to increase its commercial value.
