Which PET film is stronger than plastic composite lining ink? Source: Protective film factory direct sales Release time: 2019-05-11 Hits: 1810 PET film is a polar film, there is 45-50 dynes without processing surface tension, that is, no matter what type of plastic ink is printed on, PET The films are all very fast films. However, after the two-component polyurethane glue is applied, the same film is dry-laminated, especially after the PE film is laminated, sometimes the printing ink layer is glued from the PET glue and delamination occurs (composite thicker PE Film glue ink is even worse), that is, the printing ink layer on the PET film is partially or completely transferred to the inner film after being compounded. Because PET film has excellent barrier properties and strong anti-leakage properties, it is difficult for the solvent to penetrate, and the solvent absorption of the ink is relatively poor. The binder (resin) of the plastic surface printing ink has a good affinity with the PET film, so printing on the PET film is stronger than the printing ink in the plastic composite.
