Claims
- 1. A multilayered structure consisting essentially of at least one gas barrier layer of an ethylene-vinyl alcohol copolymer having an ethylene content of 20 to 50 mol % and an oxygen transmission rate measured at 20.degree. C., 65% RH of not more than 10 cc. 20.mu./m.sup.2 .multidot.day.multidot.atm.; at least one protective layer to protect said gas barrier layer, and from 0.1% to 50% by weight of a deodorant incorporated in either or both of said layers, the weight % of said deodorant being based upon the weight of the layer in which said deodorant is incorporated, said multilayered structure providing an effective barrier against skatole and ammonia odors.
- 2. A multilayered structure as defined in claim 1 additionally containing an adhesive layer between said layers.
- 3. A multilayered structure as defined in claim 2 wherein said deodorant is incorporated in one or more of said gas barrier, protective and/or adhesive layers.
- 4. A multilayered structure as defined in claim 1 wherein the gas barrier layer comprises an ethylene vinyl alcohol copolymer blended with an ethylene copolymer resin containing 2 to 25 mol % of a member selected from the group consisting of vinyl acetate, acrylic acid esters, methacrylic acid esters, and mixtures thereof.
- 5. A multilayered structure as defined in claim 4, wherein said gas barrier layer comprises 60 to 95 parts by weight of said ethylene vinyl alcohol copolymer and 40 to 5 parts by weight of said ethylene copolymer.
- 6. A multilayered structure according to claim 1 wherein said deodorant is contained in said protective layer.
- 7. A multilayered structure according to claim 1 wherein said deodorant is a composition comprising a member selected from the group consisting of a zinc compound, an aluminum compound, a silicon compound, an iron (II) compound, and mixtures thereof.
- 8. A multilayered structure according to claim 1 wherein said protective layer is a thermoplastic resin layer.
- 9. A multilayered structure according to claim 8 wherein said thermoplastic resin layer exhibits a Young's modulus (20.degree. C.) of not more than 2.5 kg/mm.sup.2.
