[0002] PVC blister film is a plastic film made of polyvinyl chloride (PVC) material and is a plastic product made through the blister process. Blistering is a common thermoforming process that heats and softens the PVC film, then adsorbs it on the surface of the mold to form a specific shape, and finally makes a film product with a specific structure. PVC blister film can flexibly take the shape of the mold during the blister process, so it can produce a variety of different shapes of products, including packaging, containers, trays, boxes, etc. PVC film has good transparency, making it suitable for applications that require a transparent appearance, such as transparent packaging.

[0003] However, the existing PVC blister film has a low anti-scratch performance, so that the PVC blister film is easily damaged after being rubbed by hard objects during use, thereby shortening its service life. Utility Model Content

[0004] Based on this, it is necessary to provide a PVC blister film with an anti-scratch structure to address the technical problem that the existing PVC blister film has insufficient anti-scratch performance.

[0006] The PVC base film layer is provided with a plurality of grooves, and the plurality of grooves are evenly arranged on the surfaces of both sides of the PVC base film layer, thereby effectively increasing the surface area of ​​the side surfaces of the PVC base film layer.

[0007] In one embodiment, each of the above-mentioned protective layers includes a first anti-scratch layer and a second anti-scratch layer, the two first anti-scratch layers are respectively arranged on both sides of the PVC base film layer, and each first anti-scratch layer is adhered to the surface of the adhesive layer on the corresponding side facing away from the PVC base film layer; the two second anti-scratch layers are respectively arranged on the surface of the two first anti-scratch layers facing away from the PVC base film layer.

[0011] In one embodiment, the thickness ratio of the first anti-scratch layer to the PVC base film layer is 1:4-1:2.

[0012] In one embodiment, the thickness ratio of the second anti-scratch layer to the first anti-scratch layer is 1:4-1:2.

[0013] In one embodiment, each of the above-mentioned protective layers also includes a third anti-scratch layer, and the two third anti-scratch layers are respectively arranged on both sides of the PVC base film layer, and the two third anti-scratch layers are respectively arranged on the surface of the two second anti-scratch layers facing away from the PVC base film layer.

In addition, the PVC base film layer of the utility model effectively improves the surface area of ​​the side surface of the PVC base film layer by arranging a number of grooves on the two side surfaces. When the adhesive layers are respectively coated on the two side surfaces of the PVC base film layer, the adhesive can fully fill the several grooves, thereby effectively increasing the contact area between the adhesive layer and the PVC base film layer, and then strengthening the bonding strength between the adhesive layer and the several protective layers and the PVC base film layer.
