FIELD: packaging industry.
SUBSTANCE: present invention relates to compressible tubular containers made from polymer material obtained through extrusion with blowing of multilayer film without subsequent stage of lamination, and particularly to contractible tubular container, which includes side wall, which includes longitudinal welding seam or compound, wherein the multilayer polymer material has thickness of 150-350 microns, more preferably, 200-300 microns. Each layer of multilayer polymer material uses advantages in essence similar or balanced profile of molecular orientation. Present invention also relates to method of forming such container.
EFFECT: containers have improved ovality without cracking due to stresses.
