Aluminum film is a composite soft packaging material formed by coating a very thin layer of metal aluminum on the surface of plastic film using a special process. The most commonly used processing method is vacuum aluminum plating, which is to melt and evaporate the metal aluminum at high temperature in a high vacuum state, causing the vapor deposition of aluminum to accumulate on the surface of plastic film, thereby giving the surface of 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.

The most commonly used aluminum plated films currently include polyester aluminum plated film (VMPET) and CPP aluminum plated film (VMCPP). The function of aluminum plating on the surface of thin films is to block light and prevent ultraviolet radiation, which not only extends the shelf life of the content, but also improves the brightness of the film, replacing aluminum foil to a certain extent. It also has affordable, beautiful and good barrier properties. Therefore, aluminum plating film is widely used in composite packaging, mainly used in dry and puffed food packaging such as biscuits, as well as outer packaging of some medicine and cosmetics.

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.
