FIELD: packaging.
SUBSTANCE: invention relates to flexible packaging tubes for liquid or viscous products. A multilayer case of a flexible tube contains an extruded base layer and single-layer or multi-layer film at least partially surrounding the base layer. The tensile modulus of the base layer is less than 1200 N/mm2, while the tensile modulus of film is more than 3500 N/mm2.
EFFECT: invention provides for the creation of a tube with a label that has advantages of extruded tubes and IML tubes, while having resistance to cracking, flexibility of cast polymer, and which differ in elastic properties, that is, they restore their original shape after deformation.
