一种间规离型膜
摘要：
一种间规离型膜，包括非离型区（1）和离型区（2），其特征在于：非离型区（1）包含消光聚烯烃树脂、由金属茂生产的α‑烯烃聚合物树脂和Z‑N催化剂生产的C4‑C14聚烯烃树脂；离型区（2）包含氟硅树脂和Z‑N催化剂生产的C4‑C14聚烯烃树脂。该间规离型膜的非离型区（1）的热合强度≥2.5N/inch、光泽度＜30%，离型区（2）剥离力为10.0‑20gf/inch，离型残留粘接率≥80%。与现有技术相比该间规离型膜具有表面消光、抗静电、热合强度高和离型防粘的效果，且能有效防止吸湿用品背胶失粘或胶转移。
摘要（英）：

The invention relates to a syndiotactic release film. The syndiotactic release film comprises a non-release area (1) and a release area (2), and is characterized in that the non-release area (1) comprises matting polyolefin resin, alpha-olefin polymer resin produced by metallocene, and C4-C14 polyolefin resin produced by a Z-N catalyst; the release area (2) comprises fluoro-silicon resin and C4-C14 polyolefin resin produced by the Z-N catalyst. The syndiotactic release film is characterized in that the heat seal strength of the non-release area (1) is more than or equal to 2.5N/inch, and the luster is less than 30%; the striping force of the release area (2) is 10.0 to 20gf/inch, and the release residue sticking rate is more than or equal to 80%. Compared with the prior art, the syndiotactic release film has the effects of surface matting, electrostatic resistance, high heat seal strength and release sticking prevention, and can be used for effectively preventing sticking failure of back adhesive of moisture-absorbing articles or adhesive transfer.
