Problems solved by technology

In consumer electronics, daily consumer goods and other circulation fields, higher requirements are put forward for the printing activity and adhesion of barcode label inks, as well as aging resistance, high temperature resistance and tear resistance. Performances such as high temperature and tear resistance can no longer meet the needs of development
[0003] Traditional barcode labels belong to paper barcode labels, which have great performance defects in aging resistance, high temperature resistance and tear resistance, and are not resistant to washing, so they are extremely popular in the circulation of consumer electronics and consumer goods. big limit
[0004] At present, there are some polyester films used for barcode printing on the market. In order to improve the ink adhesion on the surface of the film, corona treatment is often used to enhance the ink adhesion on the surface of the film, but there are still some shortcomings as follows: (1) ink adhesion Poor focus, easy to fall off and poor stability; (2) Poor ink printing performance, affecting ink gloss; (3) Surface corona value decays quickly, not resistant to storage

Abstract

The invention discloses a polyester film for barcode printing, which comprises a polyester film layer, at least one side of the polyester film layer is covered with a high ink adhesion resin layer, and the high ink adhesion resin layer is composed of Formed by solution coating of a high ink adhesion resin formulation consisting of glycidyl methacrylate, hydroxypropyl methacrylate, N-hydroxyethyl acrylamide, methacrylate acetoacetate glycol bis It is obtained by the copolymerization reaction of ester mixed solvent and initiator. It contains a large number of double bonds and ink-friendly groups, which improves its ink adhesion and printing performance. The ink has strong stability on the polyester film, is not easy to fall off, and has high gloss. Simultaneously, the present invention adopts micro gravure roller coating process, by controlling the specific parameters in the process, the high ink adhesion resin solution is evenly coated on the polyester film surface with a certain thickness, so that the high ink adhesion resin layer and the polyester film layer are closely bonded , and then baked through the baking tunnel, the two are cured and compounded, and will never fall off.

Description

technical field [0001] The invention relates to a polyester film and a preparation method thereof, in particular to a polyester film suitable for barcode printing and a preparation method thereof. Background technique [0002] Barcode is a graphic identifier arranged according to certain coding rules to express a group of information. It is easy to operate and mature in technology. It has been widely used in many fields such as commodity circulation, book management, postal management, and banking systems. In consumer electronics, daily consumer goods and other circulation fields, higher requirements are put forward for the printing activity and adhesion of barcode label inks, as well as aging resistance, high temperature resistance and tear resistance. Performance aspects such as high temperature and tear resistance can no longer meet the needs of development. [0003] Traditional barcode labels belong to paper barcode labels, which have great performance defects in aging ...
