[Chinese Packaging Network News] PET aluminum film introduction: PET aluminum film widely used in beverages, pharmaceuticals, alcohol, cigarettes
PET aluminum film is widely used in beverages, pharmaceuticals, alcohol, cigarettes, cosmetics, food, gifts, and other packaging, is the basis for printing composite industrial raw materials, PET aluminum film production of high vacuum aluminum plating film (including color film), High-vacuum aluminized paper (including colored aluminized paper), anodized aluminum, aluminized non-woven fabrics, cigarette liners, and water soluble coatings for aluminum plating.
PET aluminum film processing:
In a high vacuum state, metal aluminum vaporizes by vaporization at a high temperature so that vapor of aluminum causes aluminum vapor deposition to accumulate on the surface of the plastic film, thereby forming a composite flexible packaging material. The aluminized film has excellent gas barrier properties, moisture barrier properties, light blocking properties, and fragrance retention, and can prolong the shelf life of the contents. Because of its beautiful appearance, it can also replace aluminum foil to a certain extent, reduce the cost of packaging, commonly used in ordinary small food packaging, such as puffed food, biscuits, mustard and so on. It is often used in high-grade packaging such as medicine, tea, and milk powder. However, the phenomenon of aluminum plating transfer, white spots, and tunneling, etc. is very likely to occur after the aluminized film is compounded, and it also brings about no small losses to the packaging manufacturers. We will summarize the practical experience in the process of composite processing of aluminized films, and hope to help improve the quality of aluminized composite products.
