Streched multilayer film casing and process for production thereof |
摘要 |
<p>A film casing suitable for automatic filling and packaging of a (semi-)fluid content material, such as sausage meat, is provided as a stretched multilayer film casing having a necessary level of heat-shrinkability while suppressing a heat-shrinkage stress. The film casing is obtained in a tubular form by joining a pair of opposite side regions of a stretched multilayer film with both surfaces. The stretched multilayer film is a polyamide-based multilayer film comprising a pair of outer layers comprising polyolefin resins of identical species, and a gas-barrier intermediate layer comprising a polyamide resin. The stretched multilayer film exhibits a heat-shrinkage stress at 50 DEG C of at most 2MPa both in longitudinal direction and in transverse direction and a hot-water shrinkability at 90 DEG C of 5 - 20 %. <IMAGE></p> |
