Abstract

PURPOSE:To manufacture film of good pinhole-proofness at low temperature and transparency, by mixing polyamide composed of caproamide as a main constituent and ethylene type ionomer of the specified value at the specified compounding ratio. CONSTITUTION:Polycaproamide obtained by melting epsilon-caprolactam, 60-95wt% and ethylene type ionomer, 5-40wt% (5-50% of carboxyl radical of the copolymer composed of alpha-olefin and alpha,beta unsaturated carboxylic acid is neutralized with zinc ion, ionized and it has a melt index larger than 7.0.) are mixed and pelletized after melting and milling. Then, a film is obtained by extrusion- forming of this pellet by an extruder having a T die. Biaxial stretch treatment is done if necessary.
