Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-3, the present utility model provides a technical solution: the utility model provides a recoverable type PET is from type membrane, including being upper and lower coincide rete 1 and glue film 2 that distribute, rete 1 is from type membrane 3 by PET and laminating and distribute in the inside lining strip 4 of its bottom constitute, inside lining strip 4 is X type structure and along PET from the length direction distribution of type membrane 3, PET is from the bottom of four corners of type membrane 3 all to be equipped with the preliminary treatment linear structure 5 that supplies the corner to buckle easily, preliminary treatment linear structure 5 distributes along the incline direction and encloses with the corner and form right triangle, four tip of inside lining strip 4 extend respectively to the bottom of four corners of PET from type membrane 3.

Based on the setting of above-mentioned structure, this recoverable type PET is from type membrane, constitute by rete 1 and glue film 2, wherein, rete 1 is from type membrane 3 and laminating in the inside lining strip 4 of its bottom surface constitutes, inside lining strip 4 is the X type structural strip of whole plastic shaping and four tip of inside lining strip 4 extend to the bottom of four corners of PET from type membrane 3 respectively, simultaneously, four corners that PET is from type membrane 3 all are equipped with preliminary treatment linear structure, make PET from type membrane 3 four corners all easily upwards turn over, specifically, in the in-process of using, operating personnel is from type membrane 3 arbitrary adjacent two corners by the turnover, two tip of inside lining strip 4 are turned up simultaneously, can cooperate inside lining strip 4 to realize PET from type membrane 3 easily tear away the protected surface of object, thereby realize the convenient recovery from type membrane 3, this recoverable type is from type membrane through improving traditional PET structure, it has in its bottom surface complex to be X type structural 4 from type membrane four corners, and be equipped with in the four corners of PET from type membrane 3 and can realize in the complete in-process of being convenient and easy to realize the turnover in the whole PET 1 is from type membrane 3 corner 4.
