Abstract

PURPOSE: To obtain the tittled film cylinder that has excellent blocking resistance and heat-seal properties and is used for the innermost layer of a multilayer bag, by manufacturing a film by means of an inflation method after mixing medium-to low-pressure polyethylene with high-pressure polyethylene in specified quantity ratios.
CONSTITUTION: The density of resin is raised and the melting point is heightened by mixing medium-to low-pressure polyethylene with density of 0.926W0.965 with high-pressure polyethylene with the low density of 0.910W0.925 in the mixing ratios of 2W30 weitht %. When a film is produced by means of a conventional inflation frocess, surfaces 2' at the insides of this film cylinder 2 are brought to coarse (rough grain is caused) conditions, an air layer is formed between the surfaces when contacting the surfaces, and adhesion at high temperatures and in high humidity is prevented, thus obtaining the film cylinder as the object that eliminates blocking.
