PURPOSE:To obtain the title film with excellent transparency, luster, slip properties, adhesive properties and adaptability for vapor deposition by using a compsn. wherein a propylene polymer is compounded with each a specified amt. of a fine spherical silica powder and a hydroxyfatty acid glyceride. CONSTITUTION:A film is prepd. by using a compsn. comparing 100 pts.wt. propylene polymer (e.g. ethylene-propylene copolymer, ethylene-propylene-butene-1 copolymer, propylene-butene-1 copolymer, etc.) with 0.01-0.5 pt.wt. fine spherical silica powder (wherein SiO2 is a main component and Al2O3, Na2O, etc., may be incorporated and 70wt.% or higher SiO2 is pref.) and 0.3-0.5 pt.wt. hydroxyfatty acid glyceride (e.g. a hydroxylated mono-, di- or triglyceride of an 8-22C fatty acid). Said film exhibits excellent transparency, luster, slip properties, adhesive properties and adaptability for vapor deposition and is suitable for deposition packaging. |
