Abstract

The invention discloses an anti-rib-forming and anti-wrinkling printing film and a preparation method thereof, wherein by means of specific components and technologies, the total thickness, as well thickness of every layer and thickness ratio, of the printing film in an A/B/C layered lamination structure are defined, so that stiffness and thickness uniformity of the printing film are improved, thereby improving the anti-rib-forming and anti-wrinkling properties thereof.

Description

technical field [0001] The invention relates to an anti-riot rib anti-wrinkle printing film and a preparation method thereof, belonging to the technical field of biaxially stretched polypropylene film. Background technique [0002] Biaxially oriented polypropylene film (BOPP) combines light, high-strength, flexible materials with a support system to form a stable curved surface structure with certain rigidity, which can withstand certain loads and cover large spaces. It has high transparency, It has good water blocking performance, and after corona treatment, it has good printing adaptability, and can be printed in color to obtain exquisite appearance effects, so it is often used as the base material of transparent adhesive tapes and label films. [0003] When BOPP is used as a printing film for transparent adhesive tape substrates, it is required that the adhesive tape roll maintain a flat, clear and transparent visual effect after the printing film is glued on the roll; wh...
