Abstract
Provided are multilayered containers comprising a layer of a composition comprising a gas barrier resin, particularly ethylene-vinyl alcohol copolymer, incorporating an inorganic powder such as mica, and a layer of a composition comprising a thermoplastic resin incorporating an inorganic powder such as mica. The containers are excellent in gas barrier properties, particularly in gas barrier properties after being retorted, while showing very little deformation during retort treatment, and further excellent in mechanical strengths.
Claims8
A multilayered container comprising a first layer of composition (A) comprising at least one inorganic powder selected from the group consisting of mica, sericite, talc and glass flake in an amount of 5 to 50% by weight of said first layer and a gas barrier resin, and a second layer of composition (B) comprising at least one inorganic powder selected from mica, sericite, talc and glass flake in an amount of 3 to 60% by weight of said second layer and a thermoplastic resin, wherein said gas barrier resin of the first layer is not the same resin as the structural thermoplastic resin of the second layer.
