A heat-shrinkable corner protector

Abstract

The present invention proposes a heat-shrinkable corner protector, including a corner protector. The corner protector is arranged at 8 top corners of a box during packaging. Each corner protector is composed of three support plates. The three support plates of each corner protector are in contact with the three surfaces at the top corners of the box body, and the corner protectors between the adjacent top corners of the box body are connected by a heat shrinkable film during packaging, and the heat shrinkable film The ends are bonded to the butt joints of the two support plates of a single corner protector facing the surface of the box, so that the cross-section of the heat shrinkable film is "L-shaped"; eight corner protectors are used to connect twelve adjacent corner protectors. The outer contour formed by the heat shrinkable film is larger than the outer contour of the box to be protected during packaging; the top corner position formed by the three support plates of the corner protector is provided with the top corner of the box body during packaging for bonding. The temporarily fixed adhesive mounting part is provided with adhesive; the heat shrinkable film is printed with an anti-counterfeiting code. The invention has the advantages of good protection effect, and can effectively prevent the outer packaging of the box from being impacted and deformed and the shrink film from being scratched and broken.

Description

technical field [0001] The invention relates to the field of packaging, in particular to a heat-shrinkable corner protector. Background technique [0002] Existing outer packaging of commodity boxes is generally packed with cartons and shrink film, such as the outer packaging of mobile phones, the sharp corners of the box are relatively sharp, and scratches and bumps can easily lead to damage to the shrink film and damage the box at the same time. The characteristics of the shrink film determine that once a sharp crack appears, its tear resistance will be greatly reduced, and it is very easy to quickly extend along the crack, which will cause inconvenience to later sales. [0003] Although the existing packaging protection field involves corner protection, its installation method is relatively troublesome. Generally, adhesive tape or glue is used to fix it. The fixing firmness is poor, and it does not have effective anti-counterfeiting or anti-tampering functions. Contents...
