Abstract
Description
Technical Field
[0001] This utility model belongs to the field of food packaging box technology, specifically relating to a PET laser film food packaging box that is resistant to scratches on the coating. Background Technology
[0002] Food packaging boxes are indispensable in the food industry. They not only need to meet basic containment and protection functions, but their aesthetics and display properties are also increasingly important. PET laser film, with its excellent transparency, gloss, and unique holographic laser visual effect, is widely used to enhance the appearance and brand recognition of food packaging boxes. This material is typically made by forming a laser pattern layer on a PET film substrate using precision molding technology, and may be supplemented with a coating (such as an aluminum plating layer) to enhance the reflective effect.
[0003] Currently, existing technologies have insufficient scratch resistance for packaging boxes. Because PET laser film (especially the laser pattern layer and coating on the surface) is relatively soft and exposed, it is very easy to rub or collide with hard objects or other packaging boxes during the production, transportation, storage, shelf display and daily handling by consumers, resulting in scratches, abrasions or even coating peeling off the surface of the laser film. Therefore, it is necessary to design a PET laser film food packaging box that is resistant to coating scratches to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide a PET laser film food packaging box that is resistant to scratches on the coating, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a PET laser film food packaging box with anti-scratch coating, comprising a base, a box body installed on the surface of the base, and a PET laser film protective layer covering the outside of the box body, wherein an isolation component is installed on the outer side of the PET laser film protective layer, and a protective component is installed on the upper side of the PET laser film protective layer.
[0006] The protective assembly includes an assembly frame pressed against the outer surface of the PET laser film protective layer, assembly plates A and B fixedly connected inside the assembly frame, and assembly seats fixedly connected to the ends of assembly plates A and B.
[0007] Preferably, both assembly plate A and assembly plate B are attached to the surface of the PET laser film protective layer, and the surface of the assembly base is provided with assembly holes.
[0008] Preferably, transparent rubber patches are symmetrically adhered to the surface of the PET laser film protective layer, and the transparent rubber patches are located inside the assembly frame.
[0009] Preferably, the isolation assembly includes a support frame fitted over the PET laser film protective layer and a limiting frame fitted over the PET laser film protective layer.
[0010] Preferably, a support plate A is symmetrically installed between the support frame and the limiting frame.
[0011] Preferably, a support plate B is symmetrically installed between the support frame and the limiting frame, and the support plate A and the support plate B are fixedly connected.
[0012] Preferably, both support plate A and support plate B are attached to the outside of the PET laser film protective layer.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. The assembly frame is internally fixedly connected with assembly plate A and assembly plate B. The assembly frame is pressed onto the outer surface of the PET laser film protective layer. Assembly plate A, assembly plate B and the assembly seat are pressed onto the surface of the PET laser film protective layer, and adhesive bonding treatment can be performed on them to protect the top of the PET laser film protective layer.
[0015] 2. Both support plate A and support plate B are attached to the outside of the PET laser film protective layer. The support frame and the limiting frame of the isolation component are fixedly connected by support plate A and support plate B, which provides anti-wear protection for the corners of the PET laser film protective layer and ensures good stability.
