摘要:
A gas-permeable porous film which is prepared by stretching a film made from a mixture containing a polyolefin resin and an inorganic filler at least uniaxially and possesses a rugged pattern on its surface. One process for producing the film comprises forming the aforesaid mixture into a film, providing on the surface of the film a rugged pattern, stretching the resulting film at least uniaxially, and forming on the stretched film thus-formed a rugged pattern by means of a heated emboss roll and simultaneously allowing the stretched film to contract.
摘要(中):
一种透气性多孔膜,其通过至少单轴拉伸由含有聚烯烃树脂和无机填料的混合物制成的膜并在其表面上具有凹凸图案而制备。 制造薄膜的一个方法包括将上述混合物形成薄膜,在薄膜的表面上提供粗糙的图案,至少单轴拉伸所得的薄膜,并在拉伸的薄膜上形成这样的凹凸图案,借助于 加热压花辊,同时允许拉伸膜收缩。
