A multi-layer material and a resin composition. |
摘要 |
<p>A multi-layer material with a layer (A) of a saponified product of an ethylene-vinyl acetate copolymer having an ethylene content of 20 to 60 mol% and a degree of saponification of at least 90% and a layer (B) of a styrene-based polymer having mainly syndiotactic configuration, or a resin composition comprising 5 to 95 parts by weight of a saponified product of an ethylene-vinyl acetate copolymer (A) having an ethylene content of 20 to 60 mol% and a degree of saponification of at least 90% and 95 to 5 parts by weight of a styrene-based polymer (B) having mainly syndiotactic configuration has gas barrier properties and markedly improved heat resistance. In a molding comprising the resin composition or the multi-layer material, contents (food) can be stored for a long period of time at ambient temperature. Moreover, after retort sterilization, the container can be heated by boiling, or in a microwave oven or a grill oven (at 220 to 240 DEG C) in the condition that the contents (food) are placed in the container.</p> |
