Abstract:
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 30μm-5mm and this sheet is stretched at least uniaxially by 1.5-8 times.
