1. A medical, pharmaceutical, or nutritional container comprising a sealable and retortable composition, said composition comprising a mixture of two components, wherein
(a) the first component comprises propylene/ethylene copolymer (A) with an ethylene content of 2 to 20 percent by weight, and (b) the second component comprises at least one propylene/[alpha]-olefin copolymer (B) and/or at least one propylene homopolymer (C),wherein
(i) the propylene/ethylene copolymer (A) has at least one DSC melting area between 30 and 110° C. having a heat of fusion of more than 1 J/g but of less than 65 J/g,(ii) the propylene/[alpha]-olefin copolymer (B) has at least one DSC melting point of 130-170° C., and(iii) the propylene homopolymer (C) has at least one DSC melting point of 130-170° C.,wherein
(A) the total amount of polymers (A), (B), and (C) is at least 80 percent by weight of the composition, and (B) the amount of polymer (A) is between 15 and 85 percent by weight of the total amount of polymers (A), (B), and (C). |
