Abstract:
Packaging envelope for the packaging of formable meat, in combination with formable meat, comprising(a) at least two layers of superimposed plastic foils, of which at least one plastic foil is elastic and the other plastic foil is at least virtually gas-impermeable; (b) said packaging envelope is permanently elastic; (c) said packaging envelope stretches immediately before and upon the placement of said formable meat in the elastic envelope; (d) said packaging envelope spontaneously contracts in its cross-section after placement of the meat and automatically forces out air present between the packaging envelope and the meat; and (e) said packaging envelope forces the formable meat into a nearly circular cross-section shape after it is placed in the packaging envelope; and wherein said packaging envelope has an expandability selected from the group consisting of a radially elastic expandability of at least 50% of the circumference of the envelope in cross-section and an elastic longitudinal expandability of at least 25%, and a combination of a radially elastic expandability of at least 50% of the circumference of the envelope in cross-section and an elastic longitudinal expandability of at least 25%.
