Patent ID: 8273280

Claim:
A method for the production of a thin-walled flexible plastic tube having an axial direction and a radial direction, said tube comprising a tube body with a tube shoulder with an emptying opening at a first end and a sealable end closure at a second end, said process comprising the steps of: injection molding the tube having a tube body wall thickness of 0.3-1.2 mm while simultaneously applying a label to the tube by injecting melted plastics into a mold and retaining the label in the mold during the injection step, wherein flexibility of said tube allows a tube content comprising soft cheese or toothpaste to be squeezed out through the emptying opening when the end closure has been sealed, wherein said label comprises a plastic film with a tensile strength in the axial direction of the tube which is at least 100 N/mm 2 measured according to DIN ISO 527-1/-3, an elongation at break which is at most 70% measured according to DIN ISO 527-1/-3 and a thickness of at most 90 μm, wherein the plastic film has a greater tensile strength and lower tensile yield limit in an orientation direction than in a direction at right angles to the orientation direction, and wherein the plastic film is oriented such that the orientation direction coincides with the axial direction of the tube.
