Description

Technical Field

[0001] The utility model relates to the technical field of hot stamping films, in particular to a hot stamping film. Background Art

[0002] Hot stamping film is a hot stamping material made by applying a coating and vacuum-depositing a layer of metal foil onto a thin film substrate. Hot stamping film generally consists of a base film, a release layer, and a color layer. It is used in the paper, plastics, cosmetics, and artificial leather / textile industries. Hot stamping film is used in the hot stamping process. It utilizes the principle of heat transfer to transfer the aluminum layer from anodized aluminum to the substrate, creating a distinctive metallic effect. Because the primary material used for hot stamping is anodized aluminum foil, hot stamping is also called anodized aluminum hot stamping.

[0003] A search revealed a patent publication number of CN216761313U, which describes a hot stamping film comprising a base film, a release layer, an image layer, a coating layer, and an adhesive layer stacked in sequence. A water-based protective layer is provided between the coating layer and the adhesive layer to prevent substances in the protective adhesive layer from penetrating into the coating layer. The water-based protective layer is preferably a water-based polyurethane protective layer. During the implementation of this solution, it was discovered that the following problems in the prior art were not adequately addressed: Hot stamping films in the form of separate membrane structures are typically attached to a roll of film. When wrapping a material, this section of hot stamping film needs to be torn from the roll. However, because the roll of film lacks a tearing mechanism, tearing easily damages the hot stamping film. Therefore, a hot stamping film that addresses this issue is urgently needed. Utility Model Content
