How large is the lamination strength ?

Refers to the bond fastness between the plastic film and the paper (board) print in the film product. The size depends on the adhesion between the plastic film, the paper (board) print and the adhesive (or hot melt adhesive). [ film lamination machine ] When laminating, the adhesion is mainly derived from the mechanical bonding force and physico-chemical bonding between the plastic film, the paper (plate) printing article and the adhesive (or hot melt adhesive).

The key to film fastness is the affinity of the glue to the print (ink and substrate). As a film coating industry, printing inks are not selectable, that is, only the film that is suitable for the ink market is the only choice, so as a pre-coating film, it can only be regarded as high quality by adapting to the performance of all inks.[ lamination machine manufacturer ]. The composite strength of the coated product is affected by the process parameters in the film production process, such as the temperature, pressure, speed of the coating process, the coating condition of the adhesive, the film tension and environmental factors. At the same time, it is affected by the printing process, such as the surface state of the printed product formed after printing, such as the thickness of the ink layer, the area and distribution of the image, the characteristics of the ink, the use of the thinner, the use of dusting, and the drying of the ink layer.
