摘要 |
A tubular sealed casing 1 for packaging foodstuff comprises a composite plastic film 2 formed into a tubular shape with the edges overlapped and heat sealed at 7 with a non-heat sealed section 8 left along an edge the upper film. The film 2 comprises a composite laminated plastic film comprising three (or more) layers 3, 4, 5 with the peel strength between the outer layer 5 and intermediate layer 3 being lower as compared to the peel strength between the inner layer 4 and intermediate layer 3. A disruption 12 of the outer layer film 5 produces separation from the intermediate film 3 adjacent the heat sealed section 7 preferentially when the casing is torn open facilitated by the slits 9. The outer layer film 5 is peeled at 13 from the intermediate film 3, so that the casing can easily be opened. <IMAGE> |
