Estimating the term…
An oxygen-absorbing multi-layer laminate suitable for preserving food, etc. due to its excellent ability of retaining flavor and taste of food, a method of efficiently producing the oxygen-absorbing multi-layer laminate and a packaging container made of the oxygen-absorbing multi-layer laminate. The oxygen-absorbing agent is interspersed between a first thermoplastic resin layer and a second thermoplastic resin layer, or sandwiched between the integrally bonded first and second thermoplastic resin layers. In the oxygen-absorbing multi-layer laminate having at least three thermoplastic resin layers, the oxygen-absorbing agent is interspersed or interposed between the adjacent layers of at least one adjacent pair. With such a construction, the oxygen-absorbing ability is improved to prolong the storage life of retaining flavor and taste of food.
An oxygen-absorbing multi-layer laminate comprising a first thermoplastic resin layer, a second thermoplastic resin layer and an oxygen-absorbing agent, particles of said oxygen-absorbing agent being locally interspersed between said first and second thermoplastic resin layers.
An oxygen-absorbing multi-layer laminate comprising a first thermoplastic resin layer, a second thermoplastic resin layer and an oxygen-absorbing agent, said first and second thermoplastic resin layers being integrally bonded to each other while interposing particles of said oxygen-absorbing agent.
An oxygen-absorbing multi-layer laminate having at least three thermoplastic resin layers, wherein particles of an oxygen-absorbing agent are locally interspersed between adjacent layers of at least one adjacent pair.
An oxygen-absorbing multi-layer laminate having at least three thermoplastic resin layers, wherein each pair of adjacent layers are integrally bonded to each other and particles of an oxygen-absorbing agent are interposed between integrally bonded adjacent layers of at least one adjacent pair.
An oxygen-absorbing multi-layer laminate comprising an oxygen-permeable layer, a porous resin layer on said oxygen-permeable layer, a thermoplastic resin layer on said porous resin layer and a gas barrier layer on said thermoplastic resin layer, wherein particles of an oxygen-absorbing agent are locally interspersed between said porous resin layer and said thermoplastic resin layer.
A method of producing an oxygen-absorbing multi-layer laminate, comprising a step of uniformly sprinkling particles of an oxygen-absorbing agent on the surface of a first thermoplastic resin film, and a step of thermally press-bonding a second thermoplastic resin film onto the sprinkled surface of said first thermoplastic resin film.
