Abstract

The purpose of the present invention is to provide a chemical product packaging film of excellent chemical resistance, which does not produce off-odor or experience change in appearance, such as yellowing, during storage for extended periods, and with which it is possible to prevent abrasion marks or soiling of the roll during unreeling from a roll. A further purpose of the present invention is to provide a chemical product packaging film which is easily peeled from a heat seal plate during packing and sealing of contents therein. The present invention is a chemical product packaging film which contains polyvinyl alcohol and a surfactant, wherein the surfactant is contained at a level of 0.9-5 mass% with respect to 100 mass% of the chemical product packaging film, the surfactant has a polyoxyethylene structure, the mol number of oxyethylene groups is 5-15 moles, and the surfactant has an HLB of 9-14.5.

Description

technical field [0001] The present invention relates to the ability to prevent scratches and contamination of the roll when the roll is sent out without causing appearance changes such as yellowing or odor during long-term storage, and to exhibit excellent performance even when packaging highly active agents such as oxidants. Chemical-resistant pharmaceutical packaging film. In addition, the present invention relates to a film for medicine packaging that is easily peeled off from a heat-sealing plate when filling and sealing contents. Background technique [0002] Polyvinyl alcohol (hereinafter also referred to as PVA) is widely used as a packaging material because of its excellent transparency, oil resistance, chemical resistance, and gas barrier properties such as oxygen. In recent years, it has also been widely used as packaging materials for foods, pharmaceuticals, industrial chemicals, and agricultural chemicals whose properties are greatly affected by oxidation-induce...
