Aluminum foil composite film is a commonly used composite roll film, typically containing pure aluminum (AL) and aluminum-plated (VMPET).
Aluminum Foil (Al)
Aluminum foil is a super-thin sheet formed by repeatedly rolling high-purity aluminum, serving as an excellent conductor of heat and a shading material.
2. The purity of the aluminum foil used in packaging is above 99.5%.
Aluminized Film
Vacuum aluminum coated film is a thin film that deposits aluminum vapor in a high vacuum state onto various base films. The thickness of the aluminum coating typically ranges from 350 to 400 Å.
Aluminum Foil Composite Film Features
High mechanical strength, light weight, non-heat bonding, metallic luster, excellent light遮挡, strong light reflection, resistance to corrosion, good barrier properties, moisture and water resistance, strong airtightness, and fragrance retention.
Aluminum Foil Coating Features
The material exhibits metallic luster, high barrier properties against gases, and moderate adhesion viscosity. After composite processing, it is prone to aluminum coating transfer phenomena.
Aluminum Foil Composite Applications
Packaging materials, high-temperature sterilization food packaging, barrier packaging (flavors, spices), and electromagnetic shielding packaging.
Aluminum-Coated Film Applications
Lightweight, non-sterilized barrier packaging, such as seaweed packaging, expanded food, and biscuit packaging.
