Heat Shrinkable Polyester Film
Heat shrinkable Plastic film is required at room temperature stability, heating (glass temperature above) contraction, and is in one direction occurs more than 50% of the heat shrinkage is ideal. Heat shrink plastic Film packaging characteristics are: paste transparent, reflecting the image of the product, tight bundle packaging, good resistance to disperse, rain, moisture, mildew, no recovery, there is a certain security function. Heat shrinkable plastic film is commonly used in the convenience of food, beverages, electronic appliances, metal products, such as packaging, especially shrink label for its main applications.
Besides being used as shrink label, the heat shrinkable plastic film has been used in the outer packing of daily commodities in recent years.

Because the printing shrinkage film can improve the appearance of products, conducive to product advertising, brand brands in the hearts of consumers to create a deep impression.Polyester Film
Heat shrink plastic film is generally made of amorphous plastic processing, such as polystyrene, polyvinyl chloride, pvdc and so on. Polystyrene (PS) Shrinkage film strength is low, do not withstand impact, it is rarely used, and polyvinyl chloride (PVC) is not conducive to recycling treatment, not in line with environmental requirements. In foreign countries, especially in Europe, polyvinyl chloride (PVC) Plastic film has been banned in the packaging field, especially in the use of food packaging.Polyester Film
Polyester (PET) Heat shrinkable film is a new type of heat shrinkable packaging material. Because it is easy to recycle, non-toxic, tasteless, good mechanical properties, especially in line with environmental protection, polyester (PET) in developed countries has become the replacement of polyvinyl chloride (PVC) Heat shrink film ideal replacement.Polyester Film
