Abstract
PURPOSE: Films made from a composition consisting of a polyethylene resin and a phenolic antioxidant are irradiated with ionizing radiation to form title films with improved transparency as well as excellent tensile strength and heat shrinking properties.
CONSTITUTION: To (A) 100 parts by wt of a polyethylene resin, are added (B) 0.01W3, preferably 0.1W1 parts of a phenolic antioxidant as 2,6-di-tert. butyl-p- cresol and the resulting composition is melt extruded into sheets or tubes of 50W100 microns in thickness. Then the sheets or tubes are irradiated with ionized radiation to an extent that the gel fraction in the molded products attains 3W80% and stretched in one direction by more than 4 times the original area under heating to a temperature of the melting point to 50°C higher.
EFFECT: Good transparency can be imparted in spite of low gel fraction and resulting films are good in melt cutting, heat sealing and transparent properties.
