Description

Technical Field

[0001] The utility model relates to the technical field of protective films, in particular to a PVC-based barrier self-adhesive protective film. Background Art

[0002] PVC film is widely used in the field of packaging film. In order to improve the protective effect of PVC film, it is necessary to increase the thickness of PVC film and adjust the flexibility by adding plasticizer, so that PVC film is easy to process and use, but lacks self-adhesiveness.

[0003] Plasticizers will have migration and precipitation problems during the use of PVC film, especially when used in high temperature environments or in contact with oils and greases. Plasticizers are more likely to precipitate, which will not only affect the appearance quality of the packaged goods, but also cause harm to the environment and human body, and needs to be improved.

[0012] Wherein, the surface hardness of the PVC protective layer is greater than the surface hardness of the self-adhesive film layer.

[0013] The beneficial effects of the utility model are as follows: a PVC-based barrier self-adhesive protective film, which improves the anti-ultraviolet effect of the printed layer and the PVC protective layer and blocks the upward precipitation of the plasticizer in the PVC protective layer through the anti-ultraviolet layer, the PVC protective layer has a large thickness and high structural strength, and has a good protective effect on the packaged object, and uses the first barrier layer and the second barrier layer to block the downward precipitation of the plasticizer in the PVC protective layer, thereby improving the safety of use, and ensures the adhesion effect with the surface of the packaged object through the self-adhesive film layer, which is convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 It is a structural schematic diagram of the utility model. DETAILED DESCRIPTION

[0015] Combine the following Figure 1 The technical solution of the utility model is further illustrated by specific embodiments.

[0016] like Figure 1 The PVC-based barrier self-adhesive protective film shown comprises: a PVC protective layer 4, a self-adhesive film layer 1, a printing layer 5, an anti-ultraviolet layer 6 and a first barrier layer 3. The printing layer 5 is covered on the top surface of the PVC protective layer 4 and can be printed and displayed with patterns.

[0017] The anti-ultraviolet layer 6 is covered on the top surface of the printing layer 5. In the present embodiment, the anti-ultraviolet layer 6 adopts a layer of transparent UV glue, which can not only improve the anti-ultraviolet effect of the printing layer and the PVC protective layer, but also does not affect the pattern display of the printing layer 5. It can also block the upward precipitation of the plasticizer in the PVC protective layer, thereby improving the safety of use.

[0018] The first barrier layer 3 is arranged on the bottom surface of the PVC protective layer 4. In the present embodiment, the first barrier layer 3 is an aluminum-plated layer. The aluminum-plated layer has a good barrier effect and can block the plasticizer in the PVC protective layer 4 from precipitating downward, thereby further improving the safety of use.

[0019] The self-adhesive film layer 1 is arranged below the first barrier layer 3. In the present embodiment, the self-adhesive film layer 1 is made of PVDC self-adhesive film, which has good self-adhesive effect, can ensure the adhesion effect with the surface of the packaged object, is convenient to use, and the PVDC self-adhesive film also has good barrier properties.

[0020] In this embodiment, the thickness of the PVC protective layer 4 is greater than the thickness of the self-adhesive film layer 1, and the surface hardness of the PVC protective layer 4 is greater than the surface hardness of the self-adhesive film layer 1. The PVC protective layer 4 has a large thickness and high hardness, which enhances the protection of the packaged object.

[0021] like Figure 1As shown, a second barrier layer 2 is provided on the top surface of the self-adhesive film layer 1 to further block the downward precipitation of the plasticizer in the PVC protective layer 4, thereby avoiding leaving residues on the surface of the packaged object and reducing the impact on the appearance quality of the packaged object.

[0022] In this embodiment, the second barrier layer 2 uses opaque UV glue to strengthen the combination of the self-adhesive film layer 1 and the first barrier layer 3. The structure has high stability and avoids the problem of stratification and falling off during use. The opaque effect can further enhance the anti-ultraviolet protection of the self-adhesive film layer 1.

[0023] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
