Description

Technical Field

[0001] The utility model belongs to the technical field of PET protective films, and particularly relates to an antistatic PET protective film. Background Art

[0002] Antistatic PET protective films are mainly used for protecting the surfaces of various glasses and plastics, that is, they do not leave glue residues and can control the peeling voltage, so that no large voltage will be generated when the protective film is peeled off to break through the adhered object. They are mainly divided into two types: single-sided (adhesive side) antistatic and double-sided (adhesive side, reverse side) antistatic.

[0003] For single-sided antistatic on the adhesive side, the principle is to add an antistatic agent to the glue and then coat the glue to make it have antistatic effect.

[0004] For reverse side antistatic, there are two methods: one is to coat an antistatic coating on the PET film, and the other is to add an antistatic agent during the production of PET. For the former method of adding a coating, it is easy to damage the coating during storage and transportation, thus weakening the antistatic effect. This is why the storage period of antistatic protective films is shorter than that of ordinary protective films. Its advantage is low cost.

[0005] Existing antistatic PET protective films have no functions themselves. Therefore, during cutting, it is necessary to rely on the measurement of external equipment to achieve smooth cutting, which is rather inconvenient to operate. And this kind of problem is also prominent in the measurement of cutting length. Therefore, there are great limitations in actual use and there is room for improvement. Summary of the Utility Model

[0006] The purpose of the utility model is to provide an antistatic PET protective film to solve the problem of inconvenient operation during cutting of existing antistatic PET protective films as mentioned in the above background art.

[0007] To achieve the above purpose, the utility model provides the following technical solution: an antistatic PET protective film, comprising

[0008] a film body;

[0009] alignment notches, which are equidistantly arranged at the positions of the long parallel sides of the film body. When the film body needs to be cut at equal intervals, the connection line of the alignment notches at the corresponding positions on both sides of the long parallel sides of the film body can be cut off, and

[0010] cutting notches, there are two of them, and they are symmetrically arranged at both ends of the short parallel sides of the film body. The extension line of the midpoint of the cutting notch is adjacent to the alignment notch. When the alignment notch is not needed, the edge positions of the long parallel sides of the entire film body can be cut off through the cutting notch, so as to achieve the purpose of removing the alignment notch.

[0011] Preferably, the alignment notch and the cutting notch are triangular, and the corners thereof are arc-shaped, forming a rounded corner portion to prevent scratching of external people and / or objects during use.

[0012] Preferably, guide grooves are symmetrically formed at both side edges of the top surface of the film body, and both ends of the guide grooves are connected to the cutting notches formed at both ends of the short parallel sides of the film body, facilitating guiding and cutting from the guide grooves during cutting.

[0013] Preferably, the depth of the guide groove is less than the thickness of the film body, and the guide groove is arranged adjacent to the alignment notch.

[0014] Preferably, a collar is sleeved at one end of the film body, and one end of the collar extends outward to form an extension portion. During winding of the film body, the end of the film body can be limited and wound through the extension portion to avoid warping.

[0015] Preferably, an adhesive is bonded to the inner side surface of the extension portion, and the cross-section of the adhesive is smaller than that of the extension portion, realizing adhesion to an external structure through the adhesive.

[0016] Preferably, the inner cross-sectional area of the collar is equal to the longitudinal cross-sectional area of the film body, preventing the collar from being too large and easily falling off the film body.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0018] Through the designed alignment notch and cutting notch, the antistatic PET protective film can be positioned. During processing, flat and distance-fixed cutting can be achieved without the aid of measuring tools, improving the operation efficiency. Compared with the existing conventional antistatic PET protective film, the overall functionality is improved, and the deficiencies existing in the existing antistatic PET protective film are improved.
