Description

Technical Field

[0001] The utility model relates to the technical field of degradable heat shrinkable films, in particular to a degradable heat shrinkable film. Background Art

[0002] Most of the common degradable heat shrink films on the market achieve the degradable effect by attaching a degradable layer made of degradable additives to the surface of the heat shrink film. However, since the degradable layer is exposed, when the heat shrink film is stored idle or is being used, the degradable layer on its surface has already come into contact with the air and begins to degrade, thereby reducing the service life of the degradable heat shrink film. In view of the above situation, technological innovation is carried out on the basis of the existing degradable heat shrink film. Utility Model Content

[0003] The purpose of the utility model is to provide a degradable heat shrinkable film to solve the problems raised in the above background technology.

[0008] Preferably, the thickness of the first film layer is greater than the thickness of the degradation layer, and the thickness of the second film layer is greater than the thickness of the degradation layer.

[0009] Preferably, the first film layer and the second film layer have the same size, and the first film layer and the second film layer have the same thickness.

[0011] Preferably, the bottom portion of the second film layer not in contact with the top portion of the degradation layer is fixedly attached to the top portion of the first film layer not in contact with the bottom portion of the degradation layer, and the degradation layer is wrapped between the first film layer and the second film layer.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] In the utility model, when the degradable heat shrinkable film composed of the first film layer, the degradable layer and the second film layer is heat-shrink wrapped around an object, the anti-slip pattern on the surface of the second film layer allows the user to move the object more stably to avoid slipping during movement;

[0014] The degradation layer is wrapped by the first film layer and the second film layer, so as to prevent the degradation layer from coming into contact with air and causing degradation reaction, thereby increasing the service life of the degradable heat shrinkable film.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

When the degradable heat shrinkable film composed of the first film layer 1, the degradation layer 2 and the second film layer 3 is heat-shrunk to wrap an article, the anti-slip patterns 4 on the surface of the second film layer 3 allow the user to move the article more stably to avoid slipping during movement.

When the degradable heat shrinkable film is discarded after use, it only needs to be cut open with a blade, so that the degradation layer 2 in the degradable heat shrinkable film can contact with the air, thereby causing a degradation reaction and degrading the first film layer 1 and the second film layer 3.
