AI Technical Summary
Water-based inks are prone to evaporation during printing, resulting in insufficient printing depth, unclear text, and the lack of a protective layer makes them easily damaged, reducing the lifespan of the packaging film.
A polymer substrate leveling coating, a heat insulation coating, an anti-permeation coating, and an anti-foaming and leveling agent base coating are sequentially coated on the packaging film body to form a multi-layer structure to improve the film's flatness, heat resistance, and adhesion to water-based inks.
It improves the stability of the packaging film and the adhesion of water-based inks, ensuring printing quality and extending service life.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of packaging film, and in particular to a packaging film for high-quality printing with water-based inks. Background Technology
[0002] Water-based inks are a very environmentally friendly type of ink, as their solvents are primarily water and alcohol. After printing, there is no solvent residue on the printed material, no irritating odor, and no harm to human health. The ink is safe to store, non-flammable, non-explosive, and non-corrosive, and can be stored for a long time. It can be easily diluted with tap water or ethanol before use.
[0003] Packaging films are often printed with water-based inks, but because water-based inks are volatile, they can cause insufficient printing depth and unclear text, thus reducing printing quality. In addition, traditional water-based inks lack a protective layer between the ink and the base film, making them easily damaged and reducing their service life.
[0004] Therefore, in order to solve the above problems, this utility model provides a packaging film for high-quality printing with water-based inks. By sequentially coating the base film of the packaging film body with a polymer substrate leveling coating, a heat insulation coating, an anti-permeability coating, and an anti-foaming and leveling agent bottom coating, the film's flatness, heat resistance, anti-permeability, and water-based ink adhesion are improved. The water-based ink can be printed firmly and stably, and the overall performance of the packaging film is excellent. Utility Model Content

[0006] To solve the above-mentioned technical problems, the present invention provides a packaging film for high-quality printing with water-based inks, comprising a packaging film body, wherein the outer side of the packaging film body is coated with a polymer substrate leveling coating, a high-protection coating, an anti-foaming and leveling agent undercoating coating, and a water-based ink coating. The polymer substrate leveling coating is coated on the outer side of the packaging film body, the high-protection coating is coated on the outer side of the polymer substrate leveling coating, the anti-foaming and leveling agent undercoating coating is coated on the outer side of the high-protection coating, and the water-based ink coating is coated on the outer side of the anti-foaming and leveling agent undercoating coating. The high-protection coating includes a heat-insulating coating and an anti-permeability coating.
[0007] In a preferred embodiment of the present invention, the anti-permeability coating is applied to the outside of the heat insulation coating, and the heat insulation coating is applied to the outside of the polymer substrate flat coating.
[0008] In a preferred embodiment of this invention, the coating thickness of the anti-permeability coating is greater than the coating thickness of the heat insulation coating.
[0009] In a preferred embodiment of this utility model, the coating thickness of the high protective coating is less than the coating thickness of the polymer substrate leveling coating, and the coating thickness of the defoaming and leveling agent base coating is less than the coating thickness of the polymer substrate leveling coating.
[0010] The beneficial effects of this utility model are: This utility model can improve the stability of packaging film. By sequentially coating the base film of the packaging film body with a polymer substrate leveling coating, a heat insulation coating, an anti-permeability coating and an anti-foaming and leveling agent bottom coating, the flatness, heat resistance, anti-permeability and water-based ink adhesion of the film are improved.
