Polyester film tape is a film material made of polyethylene terephthalate as a raw material, made into a thick sheet by an extrusion method, and then biaxially stretched. At the same time, it is one
This kind of polymer plastic film is more and more favored by consumers because of its excellent comprehensive performance.
The physical properties of polyester film tape: it is a colorless, transparent, glossy film with excellent mechanical properties, high rigidity, hardness and toughness, puncture resistance, friction resistance, high and low temperature resistance, chemical resistance, and oil resistance , Air tightness and good fragrance retention, it is one of the commonly used barrier composite film substrates.
Advantages of polyester film tape:
1. High strength, good rigidity, transparency, high gloss, odorless, tasteless, colorless,
2. Outstanding toughness: its tensile strength is 3 times that of PC film and nylon film, and its impact strength is 3-5 times that of BOPP film. It is resistant to wear, folding, pinholes and tearing.
3. The heat shrinkage is very small, at 120°C, only 1.25% shrinkage after 15 minutes
4. Good antistatic property, easy to vacuum aluminum plating, can be coated with PVDC, thereby improving its heat-sealability, barrier property and printing adhesion
5. Good heat resistance (-70℃), low temperature and freezing resistance (200℃), excellent steaming and boiling resistance, good oil resistance and chemical resistance, etc.
6. Except for nitrobenzene, chloroform, and benzyl alcohol, most chemicals cannot dissolve it
7. Polyester film tape has low water absorption and good water resistance, suitable for packaging food with high water content
