1. A tubular structure casing for use with food products, comprising:

  • circumferential threads extending around a periphery of a tubular casing and spaced at intervals along said tubular casing, said circumferential threads comprising an elastic thread in combination with a yarn wrapped around and along a length of said elastic thread, wherein a number of turns of said yarn are provided around said elastic thread for a given length of said circumferential threads are determined as a function of an elastic limit of said elastic thread so that said circumferential threads become taut after a predetermined amount of stretch due to said yarn being straightened to an extent where said yarn resists tensile force whereupon said circumferential threads become inextensible before the elastic limit of said elastic thread is reached.
