More Information
Summary:PURPOSE:To obtain the titled film composed of a low-density polyethylene (LDPE) or an ethylene-vinyl acetate copolymer (EVA), having excellent heat- resistance without lowering the openability of the film bag, by irradiating a film with electron radiation under specific condition. CONSTITUTION:An inflation-molded film made of LDPE or EVA (preferably having a vinyl acetate content of <=7%) having a melt flow rate of preferably 0.1-1g/10min is irradiated with electron radiation in a manner to give a film having a peel strength (between films) of 1.5-2.5kgf/15mm width at 130 deg.C under a load of 1kgf/cm . EFFECT:The film has excellent heat-sealability.
