What are the key equipment for producing PET silver paper?

The key equipment for producing PET silver paper mainly includes the following categories:

PET substrate production equipment: PET silver paper is made of polyethylene terephthalate (PET) as the substrate, so the production equipment for PET substrate is required first. These devices typically include polymerization equipment, spinning equipment, stretching equipment, etc., used for producing high-quality PET films.

Surface treatment equipment: In order to give PET film a silver like luster, special treatment is required. This may include vacuum aluminum plating equipment, sputtering coating equipment, etc., which can form a uniform metallic luster layer on the surface of PET film.

Printing equipment: PET silver paper is commonly used in fields such as labels and nameplates, so it needs to be printed on its surface. Printing equipment typically includes gravure printing machines, flexographic printing machines, etc., which can ensure high-quality presentation of printed patterns and text.

Coating equipment: Coating equipment is used to apply a protective or functional coating on the surface of PET film to enhance its waterproof, oil resistant, friction resistant and other properties. These devices usually include scraper coating machines, roller coating machines, etc.

Cutting and rewinding equipment: During the production process, PET silver paper needs to be cut and rewound to meet the needs of different customers. These devices usually include slitting machines, rewinding machines, etc.

Testing and packaging equipment: In order to ensure the quality of PET silver paper, a series of testing and packaging equipment are also required. Testing equipment such as gloss meter, friction coefficient tester, etc. are used to test various performance indicators of PET silver paper; The packaging equipment is used to package PET silver paper for storage and transportation.

Please note that the above equipment is only some key equipment in the production process of PET silver paper, and other auxiliary equipment and tools may be required in the actual production process. At the same time, there may be differences in production equipment and technology among different manufacturers, so the specific equipment configuration may vary from manufacturer to manufacturer.
