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.
