Problems solved by technology

[0005] However, when online coating is used for some printed products that require special treatment, it is prone to delamination
For example, the ink used on the surface of digital prints often contains silicone oil or wax. Silicone oil and wax contain a large amount of inorganic components. It is not easy to combine with the hot melt adhesive in the pre-coated film when covering the film. The degree of bonding between the printed matter and the film is not enough , especially in the rolling line and embossing after lamination, it is easy to appear delamination phenomenon

Abstract

The invention discloses a scratch-resistant functional pre-coated film. The pre-coated film comprises a UV scratch-resistant resin coating, a film layer, a hot melt adhesive layer and a treatment layer arranged in sequence; the UV scratch-resistant resin coating is formed by coating the upper surface of a polymer film layer with a modified waterborne scratch-resistant coating liquid in an online coating way. Due to the adoption of the online coating way, the coating of a waterborne scratch-resistant coating is realized, the treatment process of polymer film functionalization is simplified, theenergy is saved, the finished product rate of the product can be increased, and the wear-resistant and scratch-resistant capacities of the surface treatment layer are improved.

Description

technical field [0001] The invention relates to the technical field of precoating films, in particular to a precoating film with anti-scratch function and a preparation process thereof. Background technique [0002] At present, in the pre-coating film industry, the coating methods for printed matter include offline and online coating methods. [0003] Among them, the substrate coated off-line is prone to surface defects such as scratches and pollution during repeated winding, unwinding, slitting, and handling. At the same time, the coating of off-line coating products is not easy to control evenly, and the coating is thick, which cannot meet the performance requirements of some special products. [0004] On-line coating is done on-line, the coating thickness can be adjusted, and on-line coating does not require any pretreatment of the substrate, and will not damage the bulk properties of the substrate, and has no degradation effect. Now it has become the most feasible indu...
