Abstract

PURPOSE:To obtain the titled biaxially oriented film having specific physical properties, with good tape appearance, free from possible development of width shrinkage and deep-seated flaws, by incorporating the base film with specific small quantities of inorganic particles. CONSTITUTION:The objective film can be obtained by incorporating (A) the base film with (B) 0.01-0.1(pref. 0.03-0.08)wt.% of inorganic particles such as zeolite, calcium carbonate, talc or titanium dioxide. This film has the following characteristics: 1. degree of isotacticity ... 97.5-99.7(pref. 98.0-99.5)% 2. crystallization temperature ... 104-125(pref. 110-123) deg.C 3. intrinsic viscosity ...especially pref. >=2.0.
