preparation example Construction

[0019] like figure 1 Shown, the preparation method of the cold seal film that the embodiment of the present invention provides comprises:

[0020] S100: Provide a substrate, and coat a crosslinkable printing ink on one side of the substrate, so that the surface of the substrate coated with the crosslinkable printing ink forms an ink layer;

[0021] S200: Form an ink protective layer on the surface of the ink layer away from the substrate by means of an evaporation process;

[0022] S300: Forming a patterned cold sealant on the surface of the substrate away from the ink layer.

[0023] Based on the preparation process of the above-mentioned cold-seal film, it can be seen that in the preparation method of the cold-seal film provided in the embodiment of the present invention, the cross-linkable printing ink is coated on one side of the substrate, so that the substrate is coated with a cross-linkable printing ink Form an ink layer on the surface of the substrate, and then use a...

Abstract

The invention provides a cold sealing thin film and a preparation method thereof and relates to the technical field of cold sealing packaging, so that the problem that due to the fact that a cold sealing light oil layer is not fully dried, after a cold sealing thin film is preserved for a period of time, cold sealing performance is poor is solved. The preparation method of the cold sealing thin film comprises the steps that a base material is provided; one face of the base material is coated with cross-linking printing ink, so that an ink layer is formed on the surface, coated with the ink, ofthe base material; by the adoption of the vapor deposition technology, an ink protecting layer is formed on the surface, away from the base material, of the ink layer; and patterned cold sealing rubber is formed on the surface, away from the ink layer, of the base material. The preparation method of the cold sealing thin film is used for preparing the cold sealing thin film.

Description

technical field [0001] The invention relates to the technical field of cold-seal packaging, in particular to a cold-seal film and a preparation method thereof. Background technique [0002] Cold seal film is a film formed by coating a patterned cold seal glue on the surface of the non-printing layer of the substrate. At room temperature, by applying pressure to the sealing of the packaging film, the cold-sealing adhesive on the cold-sealing film can be adhered together, thereby realizing the sealing of the article. [0003] The common cold-seal film is generally a surface-printed structure cold-seal film, and the surface-printed structure cold-seal film generally includes a cold-seal varnish layer, an ink layer, a substrate layer and a patterned cold-seal glue layer stacked together in sequence; The sealing varnish layer is used to protect the ink layer of the ink layer to ensure that the color of the cold-seal film can be relatively long-lasting; moreover, it can also prev...
