Problems solved by technology

[0005] The purpose of the present invention is to provide an innovative structural design of a new type of composite packaging material that can see through multi-layer co-extruded color-changing films, which solves the problem of using silver cardboard, laser holographic film and see-through multi-layer co-extruded color changing existing in the prior art. The packaging product cannot highlight the uniform color change while highlighting the metal texture, or the metal texture cannot be highlighted while highlighting the consistency color change, resulting in the singleness of the packaging product, and it can also achieve the purpose of anti-counterfeiting

Embodiment 1

[0036] Such as figure 2 As shown, the white ink 23 is printed on the cardboard 21 of the aluminized film 22, then the printing surface is covered with a magic color film 24, and finally the yellow ink 25 is printed on the magic color film 24. When the light shines on the place with white ink, because the covering power of white ink is very strong, it will prevent the reflective degree of aluminum foil, so the packaging material in the place with white ink mainly shows a magic color. When the light shines on the place where there is no white ink, the packaging material is almost entirely silver. Where there is no lower white ink but an upper yellow ink layer, the packaging material is yellow with a silvery effect. Finally, the structure of packaging and decoration products with yellow with silver effect, outstanding metallic texture and outstanding effect of consistent changing colors is obtained.

Embodiment 2

[0038] Such as image 3 As shown, part of the white ink 33 is printed on the transfer cardboard 31 of the transfer aluminum layer 32, and then the printing surface is covered with a magic film 34, and then a part of the blue ink 35 is printed on the magic film with the lower white ink. When the light shines on the place with the lower white ink but no upper blue ink layer, the main body presents the changing colors of the magic film. When the light hits the place where there is lower white ink and upper blue ink layer, the packaging material mainly presents a blue color with illusion effect. When the light shines on the area where there is neither white ink nor white ink, the packaging material is almost entirely silver of aluminum foil. Finally, the structure of packaging and decoration products with blue color, outstanding metallic texture and outstanding effect of consistent color is obtained.

Embodiment 3

[0040] Such as Figure 4 Shown, print part of white ink 43 on the cardboard 41 of aluminized film 42, then cover iris film 44 on the printing surface, then print part of white ink 46 on iris film 44, finally print red ink 45 on white ink 46. When the light shines on the place where there are white ink on the top and bottom but no upper layer of red ink, the packaging material appears white; when the light shines on the place where there are white ink on the upper and lower layers and the upper layer of red ink, the main effect is red; when the light When the light shines on the place where there is white ink on the bottom and no white ink on the top and no red ink layer on the top, the packaging material mainly shows changing colors; when the light shines on the place where there is no white ink on the top and bottom, the packaging material almost shows the silver color of aluminum foil. Finally, the structure of packaging and decoration products with red effect, prominent met...

Abstract

The invention relates to the technical field of printing and packaging material and packaging containers, in particular to a novel composite packaging material structure of a see-through multilayer coextrusion color transformation film. The structure comprises five layers of structures, the first layer is base material, the second layer is a highlight reflection metal layer, the third layer is a lower ink layer at least comprising white ink, the fourth layer is the see-through multilayer coextrusion color transformation film, and the fifth layer is an upper ink layer. The highlight reflection metal layer is manufactured on the surface of the base material through a compositing, or evaporating or transferring process, the surface of the highlight reflection metal layer is covered with the lower ink layer at least comprising the white ink, and the lower ink layer at least comprising the white ink is covered with the see-through multilayer coextrusion color transformation film, and the upper ink layer is printed on the see-through multilayer coextrusion color transformation film. The novel composite packaging material structure has the advantages that in the aspect of packaging, a prominent metal color part is provided, besides, a prominent color transformation part is provided, on the premise that cost is not changed, personalization of commodities is prominent, and an anti-fake effect is achieved.

Description

[technical field] [0001] The invention relates to the technical field of printing packaging materials and packaging containers, in particular to a novel composite packaging material structure that can see through multi-layer co-extruded color-changing films. [Background technique] [0002] At present, in the field of printing and packaging materials, while satisfying the aesthetics of packaging, the requirements for packaging differentiation are also getting higher and higher. In order to seek the difference of packaging, the packaging materials gradually changed from single white cardboard, transparent film to silver cardboard, laser holographic film with various colors (laser rainbow holographic film, laser film) and see-through multi-layer co-extruded color changing film ( Iridescent film, Symphony film). The metal texture of silver cardboard, the anti-counterfeit color change of laser holographic film, and the changing color of see-through multi-layer co-extruded color ...
