AI Technical Summary

Technical Problem

Existing printing inks have insufficient adhesion and abrasion resistance on untreated plastic films, resulting in printed materials being easily scratched and peeled off, failing to meet performance requirements.

Method used

Using polyamide resin and polyketone resin in a specific ratio as the main components, along with wax and dispersant, a printing ink is formed. This ink is then directly printed onto untreated plastic film to form an ink layer, improving adhesion and abrasion resistance.

Benefits of technology

It achieves excellent adhesion and abrasion resistance on untreated plastic films, requires no corona treatment, produces excellent printing results, is suitable for a variety of plastic film substrates, meets green printing requirements, and is applicable to food, cosmetics, pharmaceutical packaging, and decorative products.

Abstract

This invention discloses a printed plastic film product and its preparation method. The printed plastic film product includes: a pre-treated plastic film substrate and an ink layer directly printed on the surface of the pre-treated plastic film substrate. The ink layer is formed by printing ink and then drying it. The printing ink includes the following raw materials in parts by weight: 45-60 parts polyamide resin, 15-25 parts polyketone resin, 5-10 parts wax, 5-60 parts organic solvent, 0.3-1 part dispersant, and 7-12 parts pigment. In the printed product of this invention, the substrate does not require pre-treatment steps such as corona treatment; it is obtained by direct printing ink onto the substrate. The resulting printed product has good adhesion and good abrasion resistance, meeting the printing performance requirements of pre-treated plastic films and is applicable to different types of pre-treated plastic film substrates.
