Abstract

PURPOSE:To obtain packaging film having a specific thickness and excellent in heat seal strength, easily tearable and cutting directivity by stretching linear polyethylene film of a specific density or a lower one at a specific magnification in the longitudinal or lateral direction. CONSTITUTION:Film made up of linear, low density polyethylene with a density of 0.94g/cc or lower is stretched by a stretcher roll or a tenter 6-20 times in the longitudinal or lateral direction, preferably 8-13 times in the lateral direction into a thickness of 10-100mum to obtain the desired heat-sealable, easily tearable film. USE:Packaging bags for food, medicine, etc.
