During the non-metallic coating, the higher gasification temperature and evaporation energy of the evaporation raw materials lead to the higher temperature of the evaporation zone during the evaporation process.
Aluminized paper can be divided into direct evaporation method and transfer method according to its production process: direct method is the method of directly placing the paper in a vacuum aluminizing machine for aluminizing.
With the development of vacuum evaporation technology and post-processing technology, the varieties and uses of vacuum aluminized films are expanding, and they are widely used in packaging, decoration and other fields.
Vacuum aluminized film is a kind of packaging material with low price, beautiful appearance, excellent performance and strong practicability because it has the characteristics of both plastic film and metal.
Aluminum plated films are usually used on packages with barrier or light shielding requirements. Therefore, the thickness, surface condition and adhesion fastness of the aluminum plated layer will directly affect the above properties.
Aluminum vapor deposition equipmentAt present, the vacuum aluminum plating equipment used for plastic film in the market mainly has two types: winding type and suspension type.
