Description

Preparation method of double-color imitation aluminum-plated film
Technical Field
The invention belongs to the technical field of printing and packaging, and relates to a preparation method of a double-color imitation aluminum-plated film.
Background
An aluminum-plated film is a packaging material formed by converting aluminum metal into aluminum vapor at high temperature and depositing the aluminum vapor on a plastic film. It has excellent metallic luster and flexibility effect and has excellent light shielding property, sealing property and barrier property. Has strong practical value in the packaging of food, medicine and light materials. In addition, the aluminum-plated film is easy to store and transport due to the flexible effect of the aluminum-plated film, compared with an aluminum foil, the aluminum-plated film greatly reduces the using amount of aluminum in the production process, reduces the production cost and can replace aluminum foil packaging to a certain extent. Based on the advantages, the aluminizer has become a widely used material in the flexible packaging industry.
The aluminum-plated film faces increasing demands by virtue of its wide application range, however, many problems of low efficiency still exist in the production process of the aluminum-plated film, and needs to be solved. Firstly, the aluminum-plated film is required to be cooled and dried after being combined with the plastic film. However, the formation process of the aluminum vapor requires as high as 1100-. Secondly, the bonding between the aluminum vapor and the plastic film requires the aluminum vapor to be completely dried to have excellent adhesion, which is another major cause of the inefficiency of aluminum plating film production. In addition, the requirement of the manufacturing process of the aluminum-plated film on the production environment is relatively high, and only one aluminum-plated film pattern can be possessed in the process flow of producing the aluminum-plated film at a time. In the face of many inefficient production processes, a new production process is urgently needed.
