Abstract
Description
Technical Field
[0001] This utility model relates to the field of hot stamping film technology, and specifically to a novel hot stamping film. Background Technology
[0002] With the continuous advancement of technology, new processes for surface decoration are constantly emerging. Traditional heat transfer film can achieve multi-color transfer. Compared with traditional heat transfer film, hot stamping film is widely used in the packaging field. Hot stamping film has vibrant and dynamic colors and also has a certain degree of anti-counterfeiting capability. The back of the hot stamping film has an adhesive layer that adheres to the object. After the adhesive layer is bonded to the object, peeling off the film layer on the front of the hot stamping film reveals an imaging layer with anti-counterfeiting patterns.
[0003] Currently, commonly used hot stamping films still have shortcomings: their structural design is unreasonable, and the overall hot stamping film is relatively soft, making it difficult to stick to objects and prone to wrinkling during the pasting process; in addition, the anti-counterfeiting patterns of existing hot stamping films are too simple, making them easy to counterfeit, resulting in difficulty in distinguishing genuine products from fakes and poor practicality. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a new type of hot stamping film with reasonable structural design, high imitation difficulty, good anti-counterfeiting effect, reliable positioning and good practicality.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel hot stamping film, comprising an adhesive backing layer, a metal positioning layer fixedly disposed on the upper surface of the adhesive backing layer, an embossed layer fixedly disposed on the upper surface of the metal positioning layer, a color-changing anti-counterfeiting layer fixedly disposed on the upper surface of the embossed layer, an anti-counterfeiting functional layer fixedly disposed on the upper surface of the color-changing anti-counterfeiting layer, a coloring layer fixedly disposed on the upper surface of the anti-counterfeiting functional layer, a transparent protective layer fixedly disposed on the upper surface of the coloring layer, a release layer disposed on the upper surface of the transparent protective layer, a base film layer fixedly disposed on the upper surface of the release layer, a placement groove disposed on the upper surface of the base film layer, and a covering layer disposed on the inner bottom surface of the placement groove;
[0006] The anti-counterfeiting functional layer includes a fragile paper layer, anti-counterfeiting lines, and a honeycomb structure layer. The anti-counterfeiting lines are disposed between the fragile paper layer and the honeycomb structure layer, and a micro-anti-counterfeiting graphic laser engraving layer is disposed at the upper end of the anti-counterfeiting lines.
[0007] The present invention is further configured such that the fragile paper layer, anti-counterfeiting lines and honeycomb structure layer are bonded together with adhesive to form an integral structure, and the upper surfaces of the fragile paper layer and the honeycomb structure layer are flush with each other, and the lower surfaces of the fragile paper layer and the honeycomb structure layer are flush with each other.
[0008] The present invention is further configured such that: a laser-engraved anti-counterfeiting code layer is provided at a local position on the upper surface of the coloring layer.
[0009] The present invention is further configured such that: the metal positioning layer and the embossed layer are fixed by adhesive or the metal positioning layer and the embossed layer are integrally formed, and both the metal positioning layer and the embossed layer are made of stainless steel.
[0010] The present invention is further configured such that the color-changing anti-counterfeiting layer is a photochromic resin coating, a thermochromic pigment coating, or a photochromic pigment coating.
[0011] The present invention is further configured such that: the coloring layer is a coloring film layer; the transparent protective layer is a PET film or a TPU film; the adhesive backing layer is a hot melt adhesive layer; and the release layer is a water wax layer with a thickness of 0.05–0.2 μm.
[0012] The metal positioning layer, embossed layer, color-changing anti-counterfeiting layer, anti-counterfeiting functional layer, coloring layer, and transparent protective layer are bonded together to form an integrated structure.
[0013] The beneficial effects of this utility model are as follows: Compared with the prior art, this utility model has a reasonable structural design. The metal positioning layer, embossed layer, color-changing anti-counterfeiting layer, anti-counterfeiting functional layer, coloring layer, and transparent protective layer are bonded together to form an integrated structure. The anti-counterfeiting functional layer includes a fragile paper layer, anti-counterfeiting lines, and a honeycomb structure layer. The anti-counterfeiting lines are positioned between the fragile paper layer and the honeycomb structure layer. A micro-anti-counterfeiting graphic laser engraving layer is provided at the upper end of the anti-counterfeiting lines. The metal positioning layer and the embossed layer are fixed by adhesive bonding or are integrally set together, enabling comprehensive anti-counterfeiting protection. The hot stamping film serves a positioning function, making it convenient for users. When the hot stamping film is pasted onto the surface of an object, it is not easy to wrinkle and the pasting operation is easy. The embossed layer and the color-changing anti-counterfeiting layer together form the innermost anti-counterfeiting structure. The anti-counterfeiting functional layer, composed of the fragile paper layer, anti-counterfeiting lines, and honeycomb structure layer, is the middle layer of anti-counterfeiting structure. The anti-counterfeiting code laser engraving layer is the outer layer of anti-counterfeiting structure. The micro anti-counterfeiting graphics laser engraving layer on the anti-counterfeiting lines in the anti-counterfeiting functional layer requires magnification with a magnifying glass or similar tool to see all the anti-counterfeiting information. It is difficult to counterfeit and has a good anti-counterfeiting effect.
[0014] The covering layer is a scratch-off silver ink coating. It is positioned directly above the laser-engraved anti-counterfeiting code layer and serves to cover the laser-engraved anti-counterfeiting code layer, providing initial anti-counterfeiting protection. Users can scratch off the covering layer when they need to view the laser-engraved anti-counterfeiting code layer. It is convenient to use and highly practical.
