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.
