Problems solved by technology

[0006] The main problems of the above-mentioned release paper/film are: 1. Use ordinary release base paper, which is coated with polyethylene or polypropylene, and then coated with silicone; or coated with a primer before use. Silicone oil coating to achieve anti-adhesive effect and release performance
Solvent-based silicone is generally used in the industry. Although it is convenient to use, a large amount of solvent remains in the processed product, which is likely to cause environmental pollution and endanger health; 2. Coating technolog

Abstract

A disposable absorbent product, comprising from top to bottom a liquid-permeable top layer, an absorbent core, a liquid-impermeable bottom layer and a syndiotactic release film, the syndiotactic release film includes a non-release area (1) and a release area (2), characterized in that: the non-release zone (1) contains matte polyolefin resin, α-olefin polymer resin produced by metallocene and C4-C14 polyolefin resin produced by Z-N catalyst; the release zone ( 2) Contains C4‑C14 polyolefin resin produced by fluorosilicone resin and Z‑N catalyst. The non-release area (1) of the syndiotactic release film has heat sealing strength ≥ 2.5N/inch, glossiness <30%, peeling force of the release area (2) is 10.0-20gf/inch, and residual adhesion rate of the release film ≥80%. Compared with the prior art, the syndiotactic release film has the effects of surface matting, antistatic, high heat-sealing strength, release and anti-adhesion, and can effectively prevent adhesive loss or adhesive transfer of sanitary products.

Description

technical field [0001] The invention relates to a disposable absorbent article, in particular to a disposable absorbent article containing a syndiotactic release film that can replace the traditional release paper / film. Background technique [0002] The release paper / film mainly plays the role of isolating viscous substances, and has been widely used in the protective layer materials of sanitary napkins, paper diapers and incontinence products. [0003] The invention patent application with the publication number CN1358625A discloses a heat-sealing anti-adhesive release paper and its manufacturing method, providing a kind of non-adhesive release paper without release paper, which can be self-adhesively sealed by pressing and heating, packaging women's hygiene It is a very fast heat-sealing release liner, which includes a packaging layer, a heat-sealing hot melt adhesive layer and a release layer. In this invention, the packaging material layer is roll paper, the isolation l...
