Tangle film with excellent printing adhesion

Abstract

The invention discloses a tangle film with excellent printing adhesion. The tangle film comprises a film and ink, the ink is printed on the outer surface of the film to form the tangle film, and the surface tension of the film is greater than or equal to 42dyn. The ink is formed by mixing corresponding toner with gold varnish in a ratio of 1:14.5-1:15 evenly, and the mixed ink is subjected to standing for at least over 24h. The gold varnish is composed of the following raw materials by weight: 11-13% of nitrocotton resin, 9-11% of rosin resin, 2.8-3.2% of acrylic resin, 0.45-0.55% of wax, 41.0-42.0% of ethyl ester, 17-19% of butyl ester, and 14-16% of ethanol. The toner at least reaches over 7000 meshes. The tangle film provided by the invention has excellent printing adhesion, can improve the pattern printing accuracy, the appearance effect and printing definition, and further improves the packaging safety of the product.

Description

technical field [0001] The invention relates to a conjunctiva, in particular to a conjunctiva with excellent printing adhesion. Background technique [0002] Kink packaging is one of the most traditional candy packaging methods. It is also known as the three major packaging methods of candy packaging along with pillow packaging and folding packaging. It has always occupied an important position in the packaging of twist packaging candy, chocolate, preserved fruit, and jerky. At the beginning, the material used was paper (cellophane) and packaged by hand. With the advent and promotion of mechanized pillow packaging machines, pillow packaging became popular because of its low cost. However, there are limitations in the packaging of pillow bag products that are basically without any aesthetic feeling. In the later stage, twist films of various plastic substrates have been successively developed and used, such as uniaxially stretched HDPE twist films, K resin twist films, and tw...

AI Technical Summary

Problems solved by technology

However, the simple packaging method and single packaging appearance cannot meet the packaging requirements and packaging grades of the product. Therefore, the twisted film combines the innovative technology of the packaging and printing industry to reflect the product information and beautify the product, thereby improving the visual effect of the packaging and improving the product grade. Enhance the economic value of the product

However, the existing printing technology and materials cannot ensure that any film material can print well after twisting, and the pattern is clear and the effect is obvious
