Description

Technical Field

[0001] The utility model relates to the technical field of cold stamping foils, in particular to an environmentally friendly cold stamping foil. Background Art

[0002] Cold stamping is a process of partially or fully printing UV glue onto a paper tape using a flexible plate, and then compounding it with a transfer film. After being irradiated with a UV lamp, the glue instantly solidifies. After being peeled off, the laser layer on the transfer film will be transferred to the paper tape according to the pattern on the printing plate, forming a gorgeous packaging effect. It is called cold stamping because it does not require heating, which is different from traditional hot stamping.

[0003] After searching, the application with patent number 202122749303.1 discloses a cold stamping foil suitable for packaging, including a stamping foil body, the stamping foil body including a base layer, the lower side of which is sequentially laminated with a peeling layer, a resin pattern layer, an electroplated aluminum layer, and a UV adhesive layer, the base layer including a polyester film layer, the peeling layer being laminated to the lower surface of the polyester film layer, the inner side of the polyester film layer being fixedly connected to an inner elastic sheet, the inner elastic sheets being fixedly connected to elastic ribs, the outer side of the elastic ribs being coiled with connecting elastic wires, and the two ends of the connecting elastic wires being fixedly connected to the inner elastic sheets;

[0004] Although the cold stamping foil suitable for packaging can reduce the tearing of the base layer through the designed inner elastic sheet, elastic ribs and connecting elastic wire, and the positioning edge is set to facilitate tearing, thereby making the hot stamping pattern more regular and avoiding burrs on the edges, the positioning edge of the cold stamping foil suitable for packaging is connected to the peeling layer and the UV adhesive layer through an easy-tear tape. When the positioning edge is torn, the fracture between the easy-tear tape and the peeling layer and the UV adhesive layer is uneven, which can easily cause burrs on the edges of the hot stamping pattern.

[0005] Therefore, we came up with environmentally friendly cold stamping foils. Utility Model Content

[0006] In response to the shortcomings of the existing technology, the utility model provides an environmentally friendly cold stamping foil, which solves the problem that when the positioning edge is torn off in the existing device, the fracture between the easy-tear tape and the peeling layer and the UV adhesive layer is uneven, which easily leads to burrs on the edge of the hot stamping pattern.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions: an environmentally friendly cold stamping foil, comprising a base layer, a peeling layer, a resin pattern layer, an electroplated aluminum layer and a UV adhesive bonding layer sequentially laminated below the base layer;

[0008] The bottom surface of the base layer is symmetrically provided with easy-to-tear portions on both sides;

[0009] The easy-tear portion includes a positioning edge, an easy-tear sticker and an easy-tear tape. The easy-tear sticker is fixedly connected to the side of the positioning edge close to the middle of the base layer. The side of the easy-tear sticker away from the positioning edge is adhered to the side edges of the resin pattern layer, the electroplated aluminum layer and the UV adhesive layer. The top surface of the positioning edge is fixedly connected to the easy-tear tape distributed in a linear array, and the top end of the easy-tear tape is connected to the bottom surface of the base layer.

[0010] Preferably, the positioning edge and the tear-away strip are both made of environmentally friendly PE film and are an integrally formed structure. The environmentally friendly PE film is a reusable, renewable, edible and degradable packaging material that is easy to recycle and reuse, is not prone to secondary pollution, and is beneficial to environmental protection.

[0011] Preferably, the base layer includes a composite film layer, a first insertion hole, a first insertion rod, a second insertion hole and a second insertion rod, wherein the strength of the base layer can be increased.

[0012] Preferably, the front side and the left side of the composite film layer are respectively penetrated by a first socket and a second socket distributed in a linear array, and the interiors of the first socket and the second socket are respectively fixed with a first plug rod and a second plug rod, wherein the first plug rod and the second plug rod are respectively arranged in the first socket and the second socket, the strength of the composite film layer can be increased, and the composite film layer can be prevented from being easily torn.

[0013] Preferably, the first and second insertion rods are both made of elastic materials, and the composite film layer is a polymer material film composited from two layers of different film materials. The first and second insertion rods can keep the interior of the composite film layer connected when it is torn, thereby avoiding the peeling layer, resin pattern layer, electroplated aluminum layer and UV adhesive layer on the lower side from cracking. Through compounding, a material with the comprehensive properties of each single material can be obtained.

[0014] Preferably, the two layers of different film materials are PC film and PET film respectively, wherein the composite film layer can have the high mechanical properties of PC and the high temperature resistance of PET material, and is more durable.

[0015] The utility model provides an environmentally friendly cold stamping foil. It has the following beneficial effects:

[0016] 1. This environmentally friendly cold stamping foil positions the edge of the hot stamping through the easy-tear portion. After hot stamping, the positioning edge and the easy-tear sticker are torn off from the sides of the resin pattern layer, the electroplated aluminum layer and the UV adhesive layer. While tearing off the positioning edge and the easy-tear sticker, the easy-tear tape can be separated from the bottom of the base layer. The positioning edge is connected to the side edges of the resin pattern layer, the electroplated aluminum layer and the UV adhesive layer through the easy-tear sticker, so that the resin pattern layer, the electroplated aluminum layer and the UV adhesive layer can be kept neat, thereby avoiding burrs on the hot stamping pattern. The positioning edge and the easy-tear sticker are both made of environmentally friendly PE film and are an integrated molding structure. Environmentally friendly PE film is a reusable, renewable, edible and degradable packaging material that is easy to recycle and reuse, is not prone to secondary pollution, and is beneficial to environmental protection. This solves the problem of uneven fracture between the easy-tear sticker and the peeling layer and UV adhesive layer when the positioning edge is torn off in the existing device, which easily leads to burrs on the edge of the hot stamping pattern.

[0017] 2. This environmentally friendly cold stamping foil, through the arrangement of the composite film layer, the first insertion rod and the second insertion rod, can maintain the internal connection of the composite film layer when the composite film layer is torn, thereby preventing the peeling layer, resin pattern layer, electroplated aluminum layer and UV adhesive layer below it from being torn. The composite film layer is composed of PC film and PET film, which can make the composite film layer have the high mechanical properties of PC and the high temperature resistance of PET material, and is more durable.
