Cold transfer anti-counterfeiting film and flexible package internally provided with cold transfer anti-counterfeiting information carrier layer

Abstract

The invention discloses a cold transfer anti-counterfeiting film and a flexible package internally provided with a cold transfer anti-counterfeiting information carrier layer. The cold transfer anti-counterfeiting film is composed of a base layer, a cold transfer anti-counterfeiting information carrier layer and a silicon oil base layer which are sequentially overlapped, wherein the cold transfer anti-counterfeiting information carrier layer is composed of a release layer, an anti-counterfeiting information layer and an adhesive sticker layer; the flexible package comprises a flexible package printing base layer and a package pattern layer printed on the flexible package printing base material; the package pattern layer is provided with a hollow part on which package patterns are not printed; the hollow part is internally provided with the cold transfer anti-counterfeiting information carrier layer; the adhesive sticker layer of the cold transfer anti-counterfeiting information carrier layer is adhered and fixed on the flexible package print base material; the outer sides of the package pattern layer and the cold transfer anti-counterfeiting information carrier layer are also sequentially provided with an adhesive layer and a protection layer in an overlapped and compounded mode. According to the invention, the cold transfer anti-counterfeiting information carrier layer can be transferred and overloaded by utilizing the cold transfer device with low manufacture cost, and the cold transfer anti-counterfeiting film and the flexible package have the advantages of high anti-counterfeiting capability, firmness and durability, and is difficult to fall off.

Description

technical field [0001] The invention relates to the field of soft packaging anti-counterfeiting technology, in particular to a cold-transfer anti-counterfeiting film and a soft package with a built-in cold-transfer anti-counterfeiting information carrier layer. Background technique [0002] On the flexible packaging of the prior art, the holographic pattern or printing information is usually hot-stamped and transferred on paper and hard plastic materials by using positioning hot-stamping equipment. However, on the one hand, this method is difficult to be popularized and applied due to the high price of hot stamping equipment, which cannot be afforded by ordinary enterprises; Suitable for flexible packaging industry. In addition, the flexible packaging materials, paper prints, aluminum can metal packaging, etc. currently on the market adopt the methods of inkjet printer printing, thermal transfer coding machine printing, laser burning, and pasting of attached code labels, et...
