PET film is a packaging film with good comprehensive properties. It has good transparency and gloss; good air tightness and fragrance retention; PET film has excellent mechanical properties, its strength and toughness are the best among all thermoplastics, and its tensile strength and impact strength are much higher than ordinary films. Dimensionally stable, suitable for secondary processing such as printing and paper bags. PET film also has excellent heat resistance, cold resistance, chemical resistance and oil resistance. Let us understand the process and characteristics of aluminized PET film:
Main product introduction of aluminized PET film
Aluminized PET film is a barrier film formed by depositing a layer of aluminum atoms on a high-quality PET film through a vacuum aluminum plating process. It has bright metallic luster, excellent gas and light barrier properties and good moisture resistance, heat resistance and puncture resistance, and can replace the use of aluminum foil.
Technical properties of aluminized polyester film
The thickness of the aluminum coating is 0.02 ~ 0.06 μm, which can be measured with a density meter.
The aluminized layer is uniform. The thickness error is less than 10% when measuring 10 points in the longitudinal direction, and the thickness error is less than 5% when measuring 18 points in the transverse direction.
Aluminum coating adhesion. Use adhesive tape to check. When the tape is removed, the coating will generally not affect the subsequent peeling off; the ultraviolet transmittance is less than 5%.
Application scope of aluminized PET film
Widely used in food packaging, high-end tobacco industry packaging, lamination, printing, self-adhesive labels, etc. It is suitable for various high-end tobacco and alcohol packaging, gift boxes and other gold and silver cardboard. It can be used for packaging and trademarks of milk powder, tea, medicine, food, etc. , laser anti-counterfeiting materials.
Characteristics of aluminized PET film
The aluminum film has good reflection ability for ultraviolet and infrared rays, blocking ultraviolet rays. At the same time, it can improve the oxygen barrier and moisture resistance of the film, and has a metallic luster.
