Stretching film is a type of plastic film with adhesive properties on one or both sides that can be stretched and tightly wrapped around the wrapped item. Self adhesive does not adhere to the surface of the wrapped item, but only exists on the surface of the film. During the packaging process, there is no need for heat shrinkage treatment, which is beneficial for saving energy, reducing packaging costs, facilitating container transportation, and improving logistics efficiency. The characteristics of stretch film type polyester film: it is stable at room temperature, shrinks when heated (above the glass transition temperature), and experiences over 70% thermal shrinkage in one direction.
The advantages of stretch film polyester film packaging are:
1. Transparent fit, reflecting the image of the product.
2. Tight packaging with good anti scattering properties. Stretch film manufacturer
3. Rain proof, moisture-proof, and mold proof.
4. Non restorative, with certain anti-counterfeiting functions.
Type of stretch film
1. Hand stretch film: packaged by hand, with a single roll weight of 3 to 5 kilograms, making it convenient for manual operation.
2. Machine stretch film: packaged by machine operation, with a single roll weight of 10 to 18 kilograms, and can also be produced according to customer's single roll weight requirements.
Stretch film polyester film is commonly used in the convenience food and beverage markets, electronic appliances, and metal products, especially in the main application field of shrink labels. Because with the rapid development of PET beverage bottles, beverage bottles such as cola, Sprite, and various fruit juices require PET heat shrink film to be matched with heat sealing labels.
They belong to the polyester category and are environmentally friendly materials that are easy to recycle and reuse.
