Embodiment 2

[0031]Embodiment 2: production line speed is 60m / min, and polypropylene resin is put into the hopper of screw extruder, after extruder is fully melted and plasticized, the melt that forms molten state is from the T-type die head (die head) of extruder Temperature 210 ~ 240 ℃) extrusion; the extruded polyolefin resin melt immediately enters the gap between the rollers formed by the rubber roller and the pressure roller. The surface roughness Ra of the rubber roller is 40μinch, and the roller surface The temperature is controlled at 60°C, the surface roughness Ra value of the pressure roller is 200μinch, the surface temperature of the roller is controlled at 40°C, the pressure between the rollers is 2bar, the roller is initially cooled to the melt, and the roller is melted at the same time. Hot pressing to obtain an embossed film with different embossments on the front and back sides, and the embossed film is then passed through a cooling roller with a surface temperature of 20°C...

Abstract

A honed embossed adhesive tape basilemma is made of pure polyolefin resin, the roughness of the front face Ra value is 20-60 mu inch, the roughness of the back face Ra value is 60-200 mu inch, the production method thereof comprises steps of melting and extruding, embossing and finishing. The honed embossed adhesive tape basilemma prepared by the invention has special honed effect, even surface roughness, even thickness stability, good longitudinal and transverse tear resistance, good anti-blocking effect and excellent gluing effect. The method of the invention does not change the inner structure of the basilemma material, thus not influencing the physical performance of the basilemma material, and being applicable to production of honed embossed adhesive tape basilemma and production of honed basilemma for other special uses.

Description

technical field [0001] The invention relates to a matt embossed film, an unstretched matt embossed adhesive tape base film and a production method thereof. Background technique [0002] In recent years, with people's pursuit of aesthetics, tape products with a unique matt effect have become more and more popular among consumers due to their unique elegant, simple and noble visual effects; at the same time, on some special occasions, For example, in tape products such as side-to-side and front-to-back stickers of diapers used in hygiene products, people have very high requirements for the surface roughness, hand feel, thickness uniformity, vertical and horizontal tearing performance, and glue coating performance of the base film of the tape. Although adding a matting agent to the film can make a film product with a matte effect, the addition of foreign components such as a matting agent (such film products must also be added with additives such as slip agents and antistatic a...
