Common Plastic Shrink Film Types and Characteristics

PVC shrink film

It has good transparency and glossiness, can clearly display the contents, and enhance the product's appearance. It has high flexibility and tensile strength, can adapt to the packaging of items of different shapes, and has a wide shrinking temperature range and is easy to operate. However, it releases toxic gases when burned, so its use is restricted in some areas.

PE shrink film

It is non-toxic, odorless, and environmentally friendly, suitable for food and medicine packaging. It has outstanding cold resistance and can still maintain good flexibility and shrinkage performance in low temperature environments.

PET shrink film

It has extremely high transparency and is called "crystal film", which can provide a clear display effect for products. It has excellent mechanical properties, such as high tensile strength and tear resistance, which can effectively protect products. In addition, it has good heat resistance and chemical stability, and can withstand certain temperatures and chemical erosion.

PETG shrink film

It is a modified polyester based on PET, copolymerized by terephthalic acid (TPA), ethylene glycol (EG) and 1,4-cyclohexanedimethanol (CHDM). The transparency and glossiness are extremely high, which can make the packaged products more upscale; the flexibility and impact resistance are excellent, and it can shrink perfectly on complex shapes and curved surfaces without cracks or damage; it has good chemical corrosion resistance; the shrinkage rate can be adjusted in advance

RPETG shrink film

The main raw material is recycled PETG material or other related waste plastics. After a series of recycling processes such as collection, classification, cleaning, crushing, and regranulation, it is processed into shrink film, which can effectively reduce the use of virgin plastics and reduce the pressure on the environment. Environmental indicators such as carbon emissions in the whole life cycle are usually better than PETG shrink film.

CPET shrink film

Compared with ordinary PET shrink film, it has a narrower shrinkage temperature range, can shrink more quickly and evenly at a specific temperature, has stronger shrinkage force, and can fit the packaged object more closely. In some physical properties, such as tensile strength and tear strength, there are further improvements.

PLA shrink film

The film with heat shrinking properties made of polylactic acid as the main raw material can be used to replace traditional non-degradable plastic shrink film in the packaging field, such as for the packaging of cosmetics, food, etc.
