SHEET OF SUCTION OXYGEN

An oxygen absorbing sheet is obtained by molding a resin composition comprising from 15 to 70% by weight of a thermoplastic resin and from 30 to 85% by weight of an oxygen absorbent into a sheet having a thickness of from 10 mu m to 5 mu m and stretching the sheet at least uniaxially at a stretch ra...

Beschreibung
Zusammenfassung:	An oxygen absorbing sheet is obtained by molding a resin composition comprising from 15 to 70% by weight of a thermoplastic resin and from 30 to 85% by weight of an oxygen absorbent into a sheet having a thickness of from 10 mu m to 5 mu m and stretching the sheet at least uniaxially at a stretch ratio of from 1.5 to 8.0. The absorbent is an iron powder, preferably of particle size 0.1-100 mu m and preferably with a halide, carbonate, sulfate or hydroxide in amount of 0.1 to 10 wt % of the total absorbent. The resin is preferably a copolymer of ethylene and a C4-12 alpha -olefin, a copolymer of ethylene and/or butene-1 and propylene, a copolymer of ethylene and vinyl acetate and/or a (meth)-acrylic ester, or a metal salt of a copolymer of ethylene and acrylic acid. The composition can be shaped by extrusion or calendering and stretched by roll or tubular stretching uniaxially or biaxially (successively or simultaneously). The oxygen absorbing sheet is easy to handle, and its oxygen absorption capacity is controllable as desired.
