Abstract

PURPOSE: To obtain pinhole-free film excellent in tensile strength and gas barrier property, by a method wherein polyamide or the like obtined from xylylenediamine and aliphatic α,ω-dicarboxylic acid is melted, extruded in a film form, and then stretcuhed and heat-treated under specific conditions.
CONSTITUTION: A polymer (mixture) composed of 30W100 (preferably 50W 100)wt% of a polymer (e.g.; polyxylyleneadipamide and the like) containing 50mol% or more of a unit obtained from (A) meta-and/or para-xylylenediamine and 6W12C aliphatic α,ω-dicarboxylic acid and of 70W0 (preferably 50W0)wt% of (B) aliphatic polyamide (e.g.; nylon 6 and the like) is melted, extruded and then cooled quickly to get amorphous and unstretched film. Then, this film is stretched briaxially at a stretching rate of 100,000%/min or more, at 70W140°C and 3.5W5.5 times in length and in width simultaneously and then, heat-treated at 90Wmelting point minus 5°C.
