Description

Technical Field

[0001] The utility model relates to the technical field of laser films, in particular to a PET composite laser film. Background Art

[0002] In order to facilitate the use of decorative film materials, a hot melt adhesive layer is often compounded on the back of the film material. After cooling and solidifying, the hot melt adhesive layer will form a film-like structure and be compounded on the back of the film material. During use, it can be directly processed by thermal lamination. After heating, the hot melt adhesive melts again and becomes sticky, and the laser film can be laminated on the surface of other objects to be bonded. Some laser films use hot melt adhesive materials for bonding, that is, a bonding hot melt adhesive layer is pre-compounded at the back position of the laser film, and then during the bonding process, the laser film can be bonded by hot pressing lamination.

[0003] The Chinese patent with the patent number CN202320291569.2 discloses a multi-layer composite laser film. The key points of its technical solution are: including a laser film layer, a hot melt adhesive layer, a release layer and a protective layer. The hot melt adhesive layer and the protective layer are respectively arranged on both sides of the laser film layer, and the release layer is arranged between the laser film layer and the protective layer to realize the peeling of the protective layer; the protective layer includes a protective film layer and a water absorption layer. The protective film layer and the water absorption layer are laminated and bonded to each other. The protective film layer faces the release layer side, and the water absorption layer is used to adsorb moisture.

[0004] The PET composite laser film described in the above patent is difficult to copy and counterfeit because of its unique laser pattern or texture, and is often used in printed matter and packaging to prevent counterfeiting. However, during its long-term use, most of the anti-counterfeiting labels of the laser film are stuck on the surface of the laser film. After being damaged, it is impossible to recover, which is likely to lead to counterfeiting. At the same time, during the long-term use of the laser film, the compressive capacity of the laser film is low, the heat insulation and sound insulation effects are too poor, and the bonding effect between each composite layer is too poor, and it needs to be replaced many times, resulting in low environmental protection performance.

However, during its long-term use, most of the anti-counterfeiting labels of the laser film are adhered to the surface of the laser film. Once damaged, they cannot be restored, which is likely to lead to the occurrence of counterfeiting. At the same time, during the long-term use of the laser film, the compressive capacity of the laser film is low, the heat insulation and sound insulation effects are too poor, and the bonding effect between each composite layer is too poor, requiring multiple replacements, resulting in low environmental performance.
