Abstract

PURPOSE: A thermoplastic resin film is embossed at a relatively low temperature lower than a specific one to produce title film suitably used as bags for medical sterilization and protecting fruits on trees because of its high gas permeation but nonpermeation of microorganisms.
CONSTITUTION: A thermoplastic film of 10W100, preferably 20W70 microns, as polyethylene film, is embossed at a temperatur of at least 20°C lower than the softening point of the film, e.g., 5W50°C to develop the pattern.
EFFECT: The resulting film is substantially nonporous; however, the gas permeation is high, e.g., 7000W25000 c.c./m2 . day in a polyethylene of 40 micron thickness.
