Description
Technical Field
The present invention relates to a decoration film, and more particularly to a decoration film applicable to flexible packaging materials, hard packaging materials or trademark stickers.
Background
The multilayer flexible packaging film is widely used for packaging food, tea, coffee and the like. Referring to fig. 1, a cross-sectional view of a prior art multi-layer flexible packaging film structure is shown. As shown in fig. 1, the basic structure of the heat-resistant film includes a transparent heat-resistant layer 500, a printed layer 510, a glue layer 520 and a heat-sealing layer 530.
Referring to fig. 2, a cross-sectional view of another prior art multi-layer flexible packaging film structure is shown. As shown in fig. 2, the basic structure of the film is a transparent heat-resistant layer 600, a printed layer 610, a glue layer 620, a functional layer 625 and a heat-sealing layer 630, wherein the functional layer 525 may be a gas-barrier layer such as aluminum foil or nylon EVOH added for increasing gas-barrier property, or a film layer added for other functions.
The heat seal layer 630 is intended to be heat sealed into bags of various sizes. Low melting point heat sealable layers such as PP, PE, EVA etc. are often used. The printed layer 610 is printed on the surface of the transparent heat-resistant layer 600 implemented by a transparent heat-resistant material such as BOPET, Nylon, or the like. Although the decoration is beautiful, the decoration is not monotonous, so that in recent years, a laser film (Hologrphic film) is used to make a more colorful decoration layer by matching with the printing.
The function of adding decoration is shown in WO 93/008084, but WO 93/008084 discloses that a laser film is additionally arranged between a heat sealing layer and an original printed decorative layer. Referring to FIG. 3, a cross-sectional view of the multi-layer flexible packaging film structure disclosed in FIG. 1 of WO 93/008084 is shown. As shown in fig. 3, the laser film 700 is a thermoplastic film coated with an environmentally friendly aqueous coating and hot-stamped.
However, the cost of the multi-layer flexible packaging film manufactured by the method is too high due to the addition of the laser film 700, and the cost of one-time lamination needs to be increased in addition to the cost of the laser film 700, which leads to high manufacturing cost. In recent years, there are many highly decorative micro-structure patterns, such as a magnifying glass film (Fresnel film), a relief film, etc., and these micro-structures can be matched with a laser pattern (the laser pattern is also a micro-structure pattern) to be recombined into a more decorative pattern, and then become the most attractive decorative pattern matched with color printing.
In addition, chinese utility model patent CN206032174U also discloses a "high decorative multilayer flexible packaging film", which is a novel patent that reduces the cost by making a microstructure on a cast polypropylene aluminized film (VMCPP). However, this solution is only applicable to a flexible packaging material having a heat sealing layer made of a cast polypropylene aluminum-plated film (VMCPP). Furthermore, if an aluminum foil layer is added to the outside of the heat seal layer to block the gas, the aluminum foil layer blocks the microstructure pattern.
To solve the above-mentioned problem of high cost, a novel decorative film structure is needed in the art.
