Hot stamping film for digital printing machine and preparation method of hot stamping film

Abstract

The invention relates to the technical field of hot stamping films, in particular to a hot stamping film for a digital printing machine and a preparation method of hot stamping film. The hot stampingfilm for the digital printing machine includes a PET hot stamping substrate, a release layer, a laser resin layer, a laser information layer, an aluminized layer, and a glue layer, wherein the PET hotstamping substrate, the release layer, the laser resin layer, the laser information layer, the aluminized layer, and the glue layer are sequentially arranged, the laser resin layer includes hydroxy-containing acrylic resins, melamine formaldehyde resins, ester solvents, and ketone chemicals. The glue layer includes an acrylic modified resin, xylene, an ester solvent, and silica powder, and the release layer is OP-wax and thus has the advantage of having low releasing force. The temperature resistance of the laser resin layer can reach above 150 DEG C. The hot stamping film for the digital printing machine is both resistant to high temperature and capable of stamping, and can be used for hot stamping different patterns without the need to change a hot stamping plate. The preparation methodof the hot stamping film for the digital printing machine has the characteristics of being simple in technology and low in production cost, and the preparation method can be suitable for large-scaleproduction.

Description

technical field [0001] The invention relates to the technical field of hot stamping film, in particular to a hot stamping film for a digital printing machine and a preparation method thereof. Background technique [0002] In the prior art, hot stamping is generally carried out in the way of flat pressing, round pressing or round pressing. However, the above hot stamping methods can basically only hot stamp thin sheets or rolls. Hot stamping, and if you need to stamp different patterns during the production process, you need to replace different hot stamping plates, and the time to replace the hot stamping plates is also longer. [0003] In addition, on the one hand, it takes a long time to make the hot stamping plate, and on the other hand, it is necessary to remake the hot stamping plate after a period of production is worn out. [0004] In addition, the temperature resistance of the printable hot stamping film in the prior art is generally 90°C to 130°C. Since digital pri...

[0002] In the prior art, hot stamping is generally carried out in the way of flat pressing, round pressing or round pressing. However, the above hot stamping methods can basically only hot stamp thin sheets or rolls. Hot stamping, and if you need to stamp different patterns in the production process, you need to replace different hot stamping plates, and the time to replace the hot stamping plates is also longer

[0003] In addition, on the one hand, it takes a long time to make the hot stamping plate, and on the other hand, it is necessary to remake the hot stamping plate after a period of production.

[0004] In addition, the temperature resistance of printable hot stamping films in the prior art is generally 90°C to 130°C. Since digital printers are hot stamped on a wide range of substrates, 130°C can no longer meet market demand.
