TW201819172A - Microstructure transfer film improvement comprising a substrate layer and a microstructure layer which can be recycled for repeated use to effectively reduce production costs - Google Patents

Abstract

A microstructure transfer film improvement mainly comprises: a substrate layer; a microstructure layer formed on the substrate layer and fixedly formed with the substrate layer into one body; a metal reflective layer steam-plated on the microstructured layer; and a transfer layer formed on the metal reflective layer. Stripping can be performed between the metal reflective layer and the microstructure layer to easily and readily obtain a microstructure transfer film composed of a metal reflective layer and a transfer layer. The completeness of the substrate layer and the microstructure layer, after being stripped, can be maintained for recycling for repeated use, thereby effectively reducing production costs.

Description

   Improvement of microstructure transfer membrane   

The invention relates to the improvement of a microstructure transfer film, especially the manufacture of a microstructure transfer film is simple and fast, and after the substrate layer and the microstructure layer are peeled off, it can be recycled and reused to effectively reduce production costs.

Press, micro-structured film, that is, vapor-deposited film with laser holographic micro-structured lines on the surface, such as cat's eyes, lenses, holograms, floating shadows, etc., which can use the interference of light to produce colorful colors, and the pattern is obviously bright and colorful, with an iridescent effect Jia also has anti-counterfeiting effects, and is widely used in various high-quality boutique packaging.

Common microstructured films can be laminated with paper and then applied to the packaging of high-end alcoholic beverages, but they cannot be used on cigarettes. Mainly because of relevant laws and regulations, the microstructured film on cigarettes must be used. Transfer paper, that is, a transfer film must be made before transferring to the paper.

Please refer to Figure 4, which is a schematic diagram of the production of a traditional microstructure transfer film. When manufacturing, first prepare a roll of base material layer 910, and the front end of the production layer passes the coating head R3 on the roller R1 and the storage tray R2, and applies a hardenable resin transfer layer 920 on one side of the base material layer 910, that is, ultraviolet rays. The hardenable glue (UV glue) passes through the support wheel R4 to the other roller group R5, and then the hardenable resin transfer layer 920 (UV glue) on the substrate layer 910 is rolled over a microstructure plate wheel R6. The ultraviolet irradiation unit R7 disposed at the opposite side is irradiated and solidified to form a microstructure surface 930 on the hardenable resin transfer layer 920. As shown in FIG. 5, a metal reflective layer is evaporated on the microstructure surface 930 940, and a hot-melt adhesive layer 951 is provided on the metal reflective layer 940 to facilitate subsequent transfer to the paper box 2 or the surface of the paper for application.

However, the cost of the UV adhesive material of the hardenable resin transfer layer 920 is quite expensive, which is about RMB 60 to 100 per kilogram, which causes a significant increase in manufacturing costs. Moreover, when the conventional microstructure transfer film is transferred to paper for application, once the substrate layer 910 is torn off, it will instantly distort and wrinkle, which cannot be recycled in a roll, causing waste, which is its main disadvantage.

In order to solve the disadvantages of the above-mentioned conventional manufacturing of microstructure transfer films, such as excessive material costs and product application defects, the main purpose of the present invention is to provide an improvement of a microstructure transfer film, including: a substrate layer; a microstructure Layer, formed on the substrate layer, and integrated with the substrate layer; a metal reflective layer, which is deposited on the microstructure layer, and a transfer layer, which is formed on the metal reflective layer Above; a preferred implementation, wherein the transfer layer is further provided with a hot-melt adhesive layer.

Therefore, when the present invention is applied, the metal reflective layer and the microstructure layer can be peeled off, and a microstructure transfer film composed of a metal reflective layer and a transfer layer can be simply and quickly obtained, and after the substrate layer and the microstructure layer are peeled off, , And can be kept intact for recycling and reuse, thereby effectively reducing production costs.
