Abstract:
A laminated film comprising:a synthetic resin layer comprising a synthetic resin containing nitrogen atom(s) in structural units thereof; and a layer comprising a polyolefin-based resin, at least one of the synthetic resin layer comprising a synthetic resin containing nitrogen atom(s) in structural units thereof and polyolefin-based resin layer containing an iron compound catalyst having a phosphorus content of 0.0001 to 0.02% by weight, a sulfur content of 0.001 to 0.3% by weight and a sodium content of 0.001 to 0.3% by weight, comprising at least one iron oxide-based compound selected from the group consisting of iron oxide hydroxide particles or iron oxide particles, which has an average particle size of 0.05 to 2.0 &mgr;m; and has a catalytic activity capable of converting not less than 15% by mole of carbon monoxide into carbon dioxide when measured under the test conditions such that while passing an argon gas as a carrier gas, carbon monoxide supplied in a pulse amount of 6.1Ã—10âˆ’7 mole, is contacted with 2.8Ã—10âˆ’4 mole of iron oxide-based particles obtained by heat-treating said iron compound catalyst at 800Â° C. for 15 minutes in air (pretreatment), at 250Â° C. at a space velocity of 42,400 hâˆ’1 using a pulse catalytic reactor.
