UV cold transfer printing double-surface laser process

Abstract

The invention belongs to the field of laser film manufacturing processes, and in particular, relates to an UV cold transfer printing double-surface laser process. The UV cold transfer printing double-surface laser process is characterized by comprising the steps of: 1) PET film coating; 2) mold pressing; 3) recoiling; and 4) UV laser transfer: the UV laser transfer production is performed on the other surface of a PET film; a BOPP laser transfer film is adopted as a laser pattern template, and is coated with laser gloss oil; then, a gloss oil surface on the PET film and a laser information surface of the BOPP laser transfer film are compounded, and are dried by an UV drying device; after drying, two layers of films are stripped off; and laser information on the surface of the BOPP laser transfer film is transferred to the UV gloss oil layer of the PET film to form PET forward and reverse double-surface laser effect; and 5) laser layer protection: and the vacuum aluminum plating is performed for a coated mold pressing layer on the PET film to form an aluminum plating layer. The UV cold transfer printing double-surface laser process has the advantage of stable and reliable process. The UV cold transfer printing double-surface laser process can realize the laser effect on both frontal and reverse surfaces of the film to greatly improve the product appearance effect and antifake performance.

Description

technical field [0001] The invention belongs to the field of laser film manufacturing technology, and in particular relates to a double-sided laser technology for UV cold transfer printing. Background technique [0002] Laser film has a novel and bright appearance, and also has high-tech anti-counterfeiting functions. It has been widely promoted, such as in food, medicine, daily chemical products, tobacco and wine, clothing, gift packaging and decorative materials. Faster promotion. [0003] The current laser film only has a single-sided laser effect. This is because in the traditional process, the temperature is high during molding. When the reverse side is molded, the high temperature will damage the laser effect that has been formed on the front. Contents of the invention [0004] The purpose of the present invention is to solve the defect that the current laser film only has a single-sided laser effect, and provide a UV cold transfer double-sided laser process, which ...
