Introduction and Applications of PET Heat Shrinkable Film

PET heat shrinkable film, due to its unique properties and environmental benefits, has become increasingly popular in various industries. This material is characterized by its excellent mechanical properties, non-toxicity, odorlessness, and easy recyclability, making it an ideal substitute for PVC heat shrinkable films.

The standard PET films, being crystalline high polymers, initially could achieve a heat shrinkage rate of only 30% or less. To enhance this capability, PET undergoes a modification process. By copolymerizing standard polyethylene terephthalate, a modified PET film is produced that can achieve a maximum heat shrinkage rate of over 70%. This high shrinkage ratio is a significant advancement, allowing for more versatile applications.

Characteristics of this type of PET film include stability at room temperature and a significant shrinkage when heated above its glass transition temperature, with a shrinkage capability of over 70% in one direction. These features make PET heat shrinkable film highly beneficial for a variety of packaging needs.

Key advantages of PET shrink film include:

1. Protection against rain, moisture, and mildew.

2. Tight packaging with excellent anti-scattering properties.

3. Non-reversible shrinkage that offers some level of anti-counterfeiting.

4. High transparency, enhancing the product's visual appeal.

PET shrink films are commonly used in the packaging of convenience food, beverages, electronic appliances, and metal products. A primary application is in shrink labels for PET beverage bottles, like those used for cola, sprite, and various juices. This application not only leverages the environmental friendliness and recyclability of the material but also enhances the product's appearance and brand visibility.

In recent years, there's been an increasing trend of using printed PET label film for outer packaging of everyday products. This not only protects the products from environmental factors but also allows manufacturers to leverage the packaging as a marketing tool, with beautifully printed designs that enhance brand recognition.
