The working mechanism of the pre-coating film laminating machine is to bond the plastic film coated with the adhesive and the paper printed matter after heating and pressing to form a paper-plastic product. It is a common paper printed matter at present One of the finishing processes. The coated printed matter has an extra layer of thin and transparent plastic film on the surface, which makes the surface smoother and brighter, which not only improves the gloss and fastness of the printed matter, and prolongs the service life of the printed matter, but the plastic film is also waterproof, Anti-fouling, abrasion resistance, folding resistance, chemical corrosion resistance and other protective functions.
In the pre-coating film method, the film manufacturer directly purchases the pre-coating film laminating machine, and when the film is needed, the film and the paper printed matter are hot-pressed on the pre-coating film laminating machine to complete the filming process. The pre-coating film process began in the 1990s. The hot-melt adhesive or low-temperature resin was uniformly coated on the film substrate in a quantitative and uniform manner through special equipment, and the result was a pre-coating film.
The coating categories used in the pre-coating film laminating machine industry are as follows:
1 The colorful coated ceiling is made of color-coated metal plate, imported PVC high-gloss film, PET phantom color film, coated with special adhesive on the surface of the board, and the surface pattern is rich in color and does not fade. Abrasion resistance, impact resistance, waterproof, fireproof, clear and convenient, etc., are the fashion trends of today's decorative ceiling products
2PVC high-gloss film has rich flexibility, gloss and diversified colors, completely changing the single cool color of the metal ceiling surface
