Aluminized PET film is made by coating a thin layer of aluminum onto PET film using a vacuum process. This creates a barrier film with various useful properties. Below is a simple guide to its features, uses, and performance.
1. Key Characteristics
A strong reflection of ultraviolet (UV) and infrared (IR) rays is provided.
UV light is blocked effectively.
The barrier to oxygen and moisture is improved.
A metallic shine is added to the film.
2. Common Applications
Aluminized PET film is widely used in different industries.
It can be applied to:
Food packaging
Tobacco and alcohol packaging
Gift boxes and decorative cartons
Lamination and printing
Self-adhesive labels and trademarks
Anti-counterfeiting materials (such as laser effects)
Packaging for milk powder, tea, medicine, and more
3. Performance Overview
The performance of aluminized PET film is measured in several ways:
Coating Thickness
The aluminum layer is about 0.02–0.06μm thick.
Thickness is checked using an optical density meter.
Uniform Coating
Thickness errors stay under 10% along the length (measured at 10 points over 120 meters).
Side-to-side thickness errors are under 5% (measured at 18 points).
Strong Adhesion
Adhesion is tested using tape.
The aluminum layer does not peel off after removal of the tape.
UV Blocking
The UV light transmission rate is less than 5%.
