An aluminum metallized film roll is a high-performance composite material formed by depositing a layer of aluminum atoms on the surface of plastic film through high-vacuum evaporation technology. Compared with traditional aluminum foil composite materials, it retains excellent barrier properties against water vapor, oxygen, light, and aroma while significantly reducing material consumption and cost. It has become an irreplaceable key material in packaging, electrical insulation, construction, electronics, and other industries.
The base material is mainly plastic film with stable performance and good ductility. Common substrate types include polyester film, polypropylene film, polyethylene film, and polyamide film. These materials provide advantages in temperature resistance, tensile strength, transparency, and flexibility.
The aluminum coating is formed in a high-vacuum environment. This coating is extremely thin but dense, forming a continuous metal layer. High-quality aluminum metallized film roll features uniform coating distribution, no pinholes, and stable physical properties.
The composite structure combines the flexibility of plastic and the barrier properties of metal. It avoids the brittleness and high cost of pure aluminum foil while expanding application adaptability.
The process requires a stable high vacuum environment to prevent oxidation and ensure proper aluminum deposition.
Tension control is crucial to prevent deformation, wrinkles, or uneven coating.
The evaporation rate and film speed determine coating thickness and product performance.
Processes include slitting, corona treatment, and lamination to meet different application requirements.
It effectively blocks oxygen, moisture, and light. Light-shielding rate can exceed 99%, making it suitable for sensitive products.
It offers excellent tensile strength, flexibility, and resistance to cracking compared to aluminum foil.
The film provides heat reflection, conductivity, and electromagnetic shielding.
It uses less aluminum, reduces costs, and supports environmentally friendly packaging trends.
