SINGLE-LAYER TUBULAR FILM OF POLYMIDE FOR PACKAGING PASTE SUBSTANCES. |
摘要 |
The present invention relates to a tubular film used for packing foodstuffs in paste form, this tubular film being of polyamide that can absorb at least 5% water, and which at an internal pressure between 0 and 0.6 bar permits substantially reversible deformation and which has a matt appearance. The present invention also relates to a process for the production of this tubular film by multiaxial stretching of the primary tube with stretch ratios of at least 1:2.3 in the longitudinal direction and at least 1:2.5 in the transverse direction, and total thermal fixing of the stretched tube during controlled shrinkage. In addition, the invention describes a boiled or cooked sausage as well as a soft cheese, these being packed in a tubular film according to the invention. |
