Aluminum plating film is a bright metallic colored film formed by evaporating high-purity aluminum wire into a gaseous state at high temperatures (1100-1200 ℃) through vacuum aluminum plating process. When the plastic film passes through the vacuum evaporation chamber, the gaseous aluminum molecules precipitate onto the surface of the plastic film.

Aluminum method is the process of melting and evaporating metallic aluminum at high temperatures under high vacuum conditions, allowing the vapor deposition of aluminum to accumulate on the surface of plastic films, thereby giving the plastic film a metallic luster. Due to its characteristics of both plastic film and metal, it is a cheap, beautiful, high-performance, and practical packaging material.

Product features

(1) Saves energy and materials, reduces costs.

(2) It has excellent bending resistance and good toughness, with few pinholes and cracks, and no bending or cracking phenomenon, thus improving its barrier to gases, water vapor, odor, light, etc.

(3) Has excellent metallic luster, with a light reflectivity of up to 97%; And it can form a colored film through coating treatment, which has a decoration effect that aluminum foil cannot match.

(4) Shielding can be used for partial aluminum plating to obtain any pattern or transparent window, allowing for visibility of the contents.

(5) The aluminum coating has good conductivity and can eliminate static electricity effects; Its sealing performance is good, especially when packaging powdered products, it will not contaminate the sealing part, ensuring the sealing performance of the packaging.

(6) Has good adaptability to post-processing such as printing and lamination.

Due to the above characteristics, aluminum plated films have become a new type of composite film with excellent performance, economic aesthetics, and have replaced aluminum foil composite materials in many aspects. Mainly used for vacuum packaging of flavored foods and agricultural products, as well as packaging of drugs, cosmetics, and cigarettes. In addition, aluminum plated thin films are also widely used as hot stamping materials and trademark label materials in printing.
