| 摘要 |
The novel feature in a tubular, biaxially-stretched, biodegradable and compostable food (especially sausage) casing is that at least one layer is of a thermoplastically-processable biodegradable polymer, preferably an aliphatic or partly aromatic polyester, a thermoplastic aliphatic polyesterurethane, an aliphatic-aromatic polyestercarbonate or, especially, an aliphatic polyesteramide. The polymer is preferably melt extruded, cooled to solidify and then biaxially stretched. |
