The impact of PET film on laminating-film supplier

by:POLYVA     2021-11-16
PET film has excellent barrier properties and strong anti-leakage properties, so it is difficult for the glue layer molecules to penetrate. Compared with ink, it has a worse absorption of glue molecules. Therefore, if the PET film is not surface treated, the adhesive layer will often separate from the film after laminating. In order to enhance the bonding strength of the glue and PET, the PET film must be corona treated, that is, the surface of the film is roughened by high-frequency and high-voltage, and its wettability to the solvent is increased. The PET film is stretched during the production process. The rebound rate is very low, so when there are deformation processes such as die-cutting, embossing, embossing, etc., after the film is forcibly stretched again, the rebound strength is higher than other films, and the film is thicker , The greater the rebound pull. At the same time, because the paper and film are stretched in the deformed area, the adhesive layer will also be stretched and thinned, and the adhesive force will be reduced. Therefore, the amount of glue used cannot be too saved for the laminated film with this type of deformation. For deeper deformations, a small sample should be done first to confirm.
