Abstract
A multilayer tube laminate for producing a tube container, having: at least one paper layer, a polymer layer with a sealable exposed polymer surface on one side of the at least one paper layer, and a polymer coating from an olefin-based material applied directly on the at least one paper layer on another side of the at least one paper layer facing away from the sealable polymer layer; the polymer layer being formed to more than 90% by weight from a biodegradable polymer.
Claims17
A multilayer tube laminate for producing a tube container, comprising:
- at least one paper layer,
- a polymer layer with a sealable exposed polymer surface on one side of the at least one paper layer, wherein the sealable exposed polymer surface forms an inner side of the multilayer tube laminate, and
- a polymer coating from an olefin-based material applied directly on the at least one paper layer on an outer side of the at least one paper layer facing away from the sealable polymer layer,
- wherein the polymer coating is formed to more than 90% by weight from a biodegradable polymer,
- wherein the polymer coating is a protective polymer coating with a weight per area in the range from 0.5 g/m2 to 4.9 g/m2.
