摘要

PROBLEM TO BE SOLVED: To provide excellent oxygen absorbing performance, that is, increased oxygen-absorbing rate oxygen-absorbing velocity and oxygen-absorbing capacity by sandwiching a deoxidant between a thermoplastic resin film and an oxygen absorbing resin film with dispersion of a deoxidant in the thermoplastic resin to be jointed. ;SOLUTION: A deoxidizing multilayer body is formed by sandwiching a deoxidant (C-1) between a thermoplastic resin film and an oxygen absorbing resin film with dispersion of a deoxidant (C-2) in the thermoplastic resin. The deoxidants (C-1) and (C-2) may be same or different kinds, and preferably used as a deoxidant composition made by combining a main agent and an auxiliary agent which are oxidizable. Concretely, a granular deoxidant composition is dispersed on the surface of a thermoplastic resin film 4, and an oxygen absorbing resin layer 7 supplied in the molten state from a T die 2 is laminated thereon and cooled after the thermo-compression by a roller 3. Thereby, a deoxidizing multilayer body is formed in the state where the deoxidant composition is sandwiched.;COPYRIGHT: (C)2000,JPO
