Following the vacuum aluminum film and aluminum foil / plastic composite film, another new type of packaging material - transfer vacuum aluminum film is being picked up. This technology is newly developed by U.S.-based Iridian (than ITINE CO) and METAPLAST in recent years. It is currently being promoted worldwide.
The packaging material produced by the vacuum aluminum plating technology with transfer method is known for its low cost and good appearance quality. The process currently has a number of patents worldwide, and Asia has transferred the technology to the United States, the United Kingdom, West Punche, France, Scandinavia, South Korea, Myanmar, Mexico, and Brazil. And issued a technology license.
In China, vacuum aluminum coating and aluminum/plastic composite packaging materials have been produced, but due to the lack of limitations in the raw materials division, the development is relatively slow and the scope of application is not extensive. Therefore, the active promotion of the vacuum aluminum plating technology of the transfer method, the expansion of the scope of use of the basal tree, and the reduction of the cost of packing trees have important implications for the development of the packaging industry in China and narrowing the gap with the developed countries.
Transfer vacuum aluminum plating is a new process developed on the basis of direct vacuum aluminum plating technology and equipment. Its production process can be divided into the following steps:
1. The carrier film is coated with a separating agent; the carrier film generally uses biaxially oriented polyethylene film (BoPET) and biaxially oriented polypropylene film (BoPP).
2. Direct vacuum aluminum plating. The direct vacuum aluminizing is carried out on the surface of the separate carrier film, and the method and technology for aluminizing are substantially the same as the existing aluminizing equipment in China.
3. Apply a binder to the surface of the carrier film and then compound it with other substrates. The compounded tree is then dried in a drying oven. 4. Layered transfer. After drying, since the aluminized layer on the carrier is firmly bonded to the base tree, the carrier film can be separated to obtain a vacuum aluminum plating material.
Of course, if some color is added to the separating agent, the final product is also colored.
