OXYGEN ABSORBING SHEET

摘要

PURPOSE:To provide an oxygen absorbing sheet easy to handle, controlled in oxygen absorbing capacity and suppressed in the elution from the inside when the sheet comes into contact with liquid matter. CONSTITUTION:A resin compsn. consisting of 15-70wt.% of a thermoplastic resin and 30-85wt.% of a ferrous oxygen absorbent is processed into a sheet with a thickness of 30mum-5mm and this sheet is stretched at least uniaxially by 1.5-8 times. An oxygen absorbing sheet is constituted by arranging a resin layer whose oxygen transmission speed is 10000cc/m<2>. day or more at 23 deg.C on the single surface of both surfaces of the stretched sheet.
