Aluminized film:

Aluminized film is a composite flexible packaging material formed by coating a very thin layer of metal aluminum on the surface of a plastic film by a special process. The metal aluminum is melted and evaporated, so that the vapor of aluminum is deposited on the surface of the plastic film, so that the surface of the plastic film has a metallic luster. Because it has the characteristics of both plastic film and metal, it is a cheap and beautiful packaging material with excellent performance and strong practicability.

application:

At present, the most widely used aluminized films are polyester aluminized film (VMPET) and CPP aluminized film (VMCPP). The function of aluminum plating on the surface of the film is to block light and prevent ultraviolet radiation, which not only prolongs the shelf life of the contents, but also improves the brightness of the film. It replaces aluminum foil to a certain extent. , Aluminized film is widely used in composite packaging. Currently, it is mainly used in the packaging of dry and puffed food such as biscuits and the outer packaging of some medicines and cosmetics.

Features:

(1) Save energy and materials and reduce costs.

(2) It has excellent folding resistance and good toughness, and there are few pinholes and cracks, and there is no bending and cracking phenomenon, so the barrier property to gas, water vapor, odor, light, etc. is improved.

(3) It has excellent metallic luster, and the light reflectivity can reach 97%; and it can be treated with paint to form a color film, and its decorative effect is inferior to that of aluminum foil.

(4) Partial aluminum plating can be performed by shielding type to obtain any pattern or transparent window, and the contents can be seen.

(5) The aluminized layer has good electrical conductivity and can eliminate electrostatic effects; its sealing performance is good, especially when packaging powder products, it will not pollute the sealing part, ensuring the sealing performance of the packaging.

(6) It has good adaptability to post-processing such as printing and compounding.

Due to the above characteristics, the aluminized film has become a new type of composite film with excellent performance, economical appearance, and has replaced the aluminum foil composite material in many aspects. It is mainly used for the vacuum packaging of flavored food and agricultural products, as well as the packaging of medicines, cosmetics and cigarettes. In addition, aluminized film is also widely used as bronzing material and trademark label material in printing.
