Detailed Description
The utility model will be described in detail below with reference to the drawings and the specific embodiments.
Referring to fig. 2, the present utility model provides a local matte holographic laser film, comprising: a base layer and a PET local matte holographic layer.
Referring to fig. 1, the PET partially matte holographic layer includes: a PET substrate layer 1, a matte coating 2 and a laser holographic coating 3. The PET substrate layer 1 is used for providing basic support to facilitate the manufacture of the matte coating 2 and the laser holographic coating 3. In this example, the thickness of the PET base material layer 1 was 19. Mu.m. The matte coating 2 is printed on the PET substrate layer 1, and the laser holographic coating 3 is printed on the matte coating 2. Firstly, printing a matte coating 2 on a PET substrate layer 1 by using a gravure printer, wherein the matte coating 2 is modified acrylic resin with matte powder. And then, using a gravure press to print a bright-surface die-pressed laser coating 3 in a sleeved mode, wherein the laser holographic coating 3 is modified polyurethane resin, the speed of the laser holographic coating is 60 meters per minute, and the temperature of an oven is 120 ℃. And then selecting a laser pattern for die pressing, wherein the holographic laser coating at the matte position after die pressing cannot be displayed, and the bright surface position has a laser effect, so that the PET local matte holographic layer is obtained. The molding apparatus used a seamless twin-plate molding press with a 1 plate temperature of 180 c and a 2 plate temperature of 185 c, the speed being controlled according to the pattern texture depth, at 40-60 meters per minute.
Referring to fig. 2, the base layer includes: an OPP substrate layer 4 and an OPP transfer coating layer 5, wherein the OPP transfer coating layer 5 is positioned on the OPP substrate layer 4. The thickness of the OPP base material layer 4 was 22 μm. And stripping the PET substrate layer 1 of the PET local matte holographic layer, and then molding the PET substrate layer on the base surface layer to obtain the local matte holographic laser film. Specifically, the PET substrate layer 1 in the PET local matte holographic layer manufactured in the previous step is peeled off, and then is molded on the OPP transfer coating 5 through an OPP molding press, wherein the molding temperature is 120 ℃, and the molding speed is 80 meters per minute.
The local matte holographic laser film further comprises a PU coating 6, and the PU coating 6 is positioned on the upper layer of the PET local matte holographic layer 1. Comma coating is used on the OPP local matte holographic layer, a PU coating with 5-30 mu m is coated, the color is adjustable, and the PU coating is water-based polyurethane resin. The PU coating 6 has the advantages of softness, good elasticity, good strength, wear resistance, moisture resistance, dry resistance and the like.
The local matte holographic laser film further comprises a glue layer 7, and the glue layer 7 is positioned above the PU coating 6. When the whole film is transferred to the product, the film is adhered to the product 8 through the glue layer 7, and the product 8 can be leather or cloth.
The traditional local matte holographic laser film is made into full-plate matte, or full-plate laser effect, and the local matte laser effect needs to be manufactured twice. The local matte holographic laser film has the advantages that the matte and holographic laser effects are firstly manufactured on the same layer, and then transferred to a product, so that the time and the production cost are saved.
The foregoing description of the preferred embodiment of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the utility model.
