RETORT-STERILIZABLE LAMINATED STRUCTURE AND PROCESS FOR PREPARATION THEREOF |
摘要 |
<p>Disclosed is a retort-sterilizable laminated structure comprising an aluminum foil or sheet, a heat-sealable crystalline propylene type resin layer formed on one surface of the aluminum foil or sheet and a heat-resistant resin layer formed on the other surface of the aluminum foil or sheet, wherein the aluminum foil or sheet is heat-fusion-bonded to said crystalline propylene type resin layer through a layer of a modified olefin resin having a degree of crystallization of 15 to 95% and a carbonyl group concentration of 1 to 600 meq/100 g of the polymer, in which the majority of the structural olefin units are propylene units and the minority of the structural olefin units are ethylene units. As the modified olefin polymer, a modified ethylene-propylene copolymer or a blend of a modified propylene type polymer with an ethylene type polymer is preferably employed.</p> |
