Abstract

PURPOSE:To obtain a porous film or sheet having good property balance with respect to anisotropy, surface strength, etc., for both mono- and biaxially stretched products by using a raw material obtained by adding a specific compound to a polyolefinic resin. CONSTITUTION:A resin composition, obtained by adding a filler (B) (talc preferably) and a polyhydroxy saturated hydrocarbon (C) (of a number average molecular weight of 500-20,000 preferably) to a polyolefinic resin (A) (high-density polyethylene preferably), is melted and molded into a film or sheet. The film or sheet thus obtained is stretched to obtain an objective film or sheet. In this case, 100pts.wt. a polyolefin resin (A) is preferably mixed with 25-400pts.wt. the component (B) and 1-100pts.wt. the component (C). EFFECT:Both mono- and bi-axially stretched products are good in moisture permeability, weather proofness, heat resistance, etc., as well as having a high flexibility.
