PET film performance characteristics

PET film heat shrinkable polyester film features: It is stable at room temperature, when heated (above the glass transition temperature) shrink, and in one direction more than 70% of the thermal contraction. The advantages of heat shrinkable polyester film packaging are:
① body transparent, reflecting the image of goods.
Tight bundle packaging, good anti-scatter.
③ rain, moisture, mildew.
④ no resilience, there are certain anti-counterfeiting features.
Ordinary PET is a crystalline polymer, PET film through the tensile orientation, will produce a greater degree of crystallization, such as its heat-sealing, it will produce shrinkage deformation, so ordinary PET film does not have heat sealing performance. When PET film is used as commodity packaging, in order to solve the problem of heat sealing, BOPET film is usually combined with PE film or CPP film to limit the application of BOPET film to a certain extent.
PET film heat shrinkable polyester film commonly used in convenience foods, beverage markets, electronic appliances, metal products, especially shrink labels is its most important application areas. Because with the rapid development of PET bottles, such as colas, spirits, all kinds of juice and other beverage bottles require PET shrink film with its supporting heat-sealing labels, which belong to the polyester, is environmentally friendly materials, easy to recycle use.
PET film heat shrinkable polyester film in addition to shrink labels, in recent years also began to be used for commodity packaging. Because it can protect the packaging items from impact, rain, moisture, rust, but also make the product in a beautifully printed packaging to win users, at the same time it can well demonstrate the good image of the manufacturer. At present, more and more packaging manufacturers use printing shrink film instead of the traditional transparent film. Because printing shrink film can improve the appearance of the product grade, is conducive to product advertising, make the brand in the minds of consumers have a deep impression. In order to solve the problem of heat sealing, three-layer co-extruded heat-sealable PET film has been developed by modifying the PET resin and using a three-layer A / B / C die. The heat-sealable PET film Because of the heat-sealable layer, it can be directly heat-sealed, easy to use. Heat-sealable PET film can be widely used in a variety of product packaging and card protection film and other fields.
