Description

Technical Field

[0001] The utility model relates to the technical field related to release paper, in particular to a single-sided release paper structure. Background Art

[0002] Release paper is a kind of anti-adhesive paper that prevents the prepreg from sticking and protects the prepreg from contamination. Release paper is made of paper coated with anti-adhesive material, and its type is differentiated according to the material, thickness, elongation, single-sided and double-sided differences.

[0003] After massive searches, it was found that the prior art publication number is CN213447880U, which discloses environmentally friendly odorless release paper in the field of release paper, including release paper, the upper surface of the release paper is an upper silicone oil layer, the lower end of the upper silicone oil layer is fixedly connected to an upper anti-wrinkle layer, the lower end of the upper anti-wrinkle layer is fixedly connected to a bottom paper layer, the lower end of the bottom paper layer is fixedly connected to a lower anti-wrinkle layer, and the lower end of the lower anti-wrinkle layer is fixedly connected to a lower silicone oil layer. The release paper is in a roll shape and a reel is installed on the inside, a rotating shaft is installed in the reel, a handle is installed on the inside of the rotating shaft, a sealing cover is installed at the connection between the handle and the reel, a connecting cover is fixedly connected to the outer end of the handle, and a pull ring is fixedly connected to the outer end of the connecting cover, and the reel is supported by the handle. When the release paper is used, the handle is pulled out of the reel, and then the release paper can be pulled and used by holding the handle, which is convenient and quick. After the release paper is used up, the handle can be inserted into the reel for storage to reduce its occupation of space.

[0004] In summary, the existing release paper is provided with an anti-wrinkle layer and a silicone oil layer on both sides, which can play an anti-wrinkle role. However, the release paper lacks outer protection during daily storage, making its protective performance relatively general.

[0005] In view of the above-mentioned defects, the designer actively conducts research and innovation in order to create a single-sided release paper structure to make it more valuable for industrial use. Utility Model Content
