Description

Improvement of microstructure transfer film

This creation relates to the improvement of a microstructure transfer film, especially that the microstructure transfer film is simple and rapid to manufacture, and after the base layer and the microstructure layer are peeled off, the recycling can be recycled and the production cost can be effectively reduced.

According to the micro-structured film, that is, the vapor-deposited film with the laser-like holographic pattern on the surface, such as cat's eye, lens, hologram, floating shadow, etc., it can use the light interference to produce colorful colors, the pattern is obviously colorful and the rainbow effect It has anti-counterfeiting effect and is widely used in various high-quality boutique packaging.

The common microstructure film can be applied to the packaging of high-grade wine after it is covered with paper, but it cannot be used on the cigarette packaging box. The main reason is that the microstructure film on the cigarette package must be used. Transfer the paper, that is, first transfer the film and transfer it to the paper.

Please refer to Figure 4 for a schematic diagram of the production of a conventional microstructure transfer film. At the time of manufacture, a roll of the substrate layer 910 is prepared, and the front end of the substrate layer 910 is coated with a hardenable resin transfer layer 920, that is, ultraviolet rays, through the coating head R3 on the roll R1 and the stocker R2. a hardenable glue (UV glue), passing through the support wheel R4 to the other roller group R5, and then the hardenable resin transfer layer on the substrate layer 910 920 (UV glue) is rolled over a microstructured plate wheel R6, and is irradiated and shaped by the ultraviolet irradiation unit R7 disposed on the opposite side to form a microstructured surface 930 on the hardenable resin transfer layer 920, as shown in FIG. As shown, a metal reflective layer 940 is deposited on the microstructured surface 930, and a hot melt adhesive layer 951 is disposed on the metal reflective layer 940 to facilitate subsequent transfer to the carton 2 or paper surface.

However, the cost of the UV adhesive material of the hardened resin transfer layer 920 is quite expensive, and is now about RMB 60 to 100 per kilogram, resulting in a substantial increase in manufacturing costs. Moreover, when the conventional microstructure transfer film is transferred to the paper for application, once the substrate layer 910 is torn off, the wrinkles and wrinkles are instantaneously generated, and the waste cannot be recovered by recycling and recycling, which is a major disadvantage.

In order to solve the disadvantages of the above-mentioned conventional microstructure transfer film production material cost and its application, the main purpose of the present invention is to provide an improvement of the microstructure transfer film, including: a substrate layer; a microstructure a layer formed on the substrate layer and integrally fixed with the substrate layer; a metal reflective layer deposited on the microstructure layer; and a transfer layer formed on the metal reflective layer Preferably, the transfer layer is further provided with a hot melt adhesive layer.

Therefore, in the present application, the metal reflective layer and the transfer layer can be easily and quickly obtained by peeling off between the metal reflective layer and the microstructure layer, and the base layer and the microstructure layer are peeled off. And can be kept intact for recycling and repetitive manufacturing, and effectively reduce production costs.

In order to enable the reviewing committee to further understand the composition, features, and effects of the present method, a detailed description of the drawings and preferred embodiments is provided. Referring to FIGS. 1 to 3, the improvement of the microstructure transfer film provided in the present invention mainly includes: a substrate layer 11; a microstructure layer 12 formed on the substrate layer 11 and The substrate layer 11 is fixedly integrated; a metal reflective layer 13 is deposited on the microstructure layer 12 to And a transfer layer 14 is formed on the metal reflective layer 13; preferably, a transfer layer 14 is further disposed on the transfer layer 14; when applied, the transfer layer can be transferred to the paper. Box 2 on the side (as shown in Figure 2).

Preferably, the microstructure layer 12 and the transfer layer 14 can be achieved by using UV curable glue (UV glue).

Therefore, as shown in FIGS. 1 to 3, in the application, the improvement of the microstructure transfer film of the present invention can be performed by peeling off between the metal reflective layer 13 and the microstructure layer 12, and a metal reflective layer 13 and a simple and fast method can be obtained. The microstructure transfer film 10 composed of the transfer layer 14 and the base layer 11 thereof are peeled off together with the microstructure layer 12, and can be kept intact for recycling and repeated use, thereby effectively reducing the production cost, which is the creation microstructure.
