1-15. (canceled)
An inner liner sheet material for lining an inner surface of a package unit for at least one aerosol-generating article, comprising
- a base layer,
- and a barrier layer,
- wherein the base layer is provided with an infusion substance,
- wherein the inner liner sheet material is free of a metallic layer,
- wherein the base layer comprises paper, and
- wherein the infusion substance comprises at least one flavoring component.
A package unit with at least one aerosol-generating article, a container and an inner liner sheet material comprising
- a base layer,
- and a barrier layer,
- wherein the base layer is provided with an infusion substance, and
- wherein the inner liner sheet material is free of a metallic layer,
- wherein the inner liner sheet material at least partially encloses the at least one aerosol-generating article,
- wherein the inner liner sheet material is at least partially enclosed by the container,
- wherein the barrier layer is more distant from the at least one aerosol-generating article than the base layer,
- wherein the base layer comprises paper, and
- wherein the infusion substance comprises at least one flavoring component.
A method for producing an inner liner sheet material for lining an inner surface of a package unit for at least one aerosol-generating article, the method comprises the following steps:
- providing the base layer with a barrier layer, and
- providing a base layer with an infusion substance,
- wherein the barrier layer is provided directly on the base layer,
- wherein the base layer comprises paper, and
- wherein the infusion substance comprises at least one flavoring component.
Use of a biodegradable barrier layer in an inner liner sheet material for lining an inner surface of a package unit for at least one aerosol-generating article, wherein the inner liner sheet material comprises two layers, a base layer provided with an infusion substance and the barrier layer, wherein the barrier layer is the least-permeable layer of the inner liner sheet material with respect to the infusion substance, wherein the base layer comprises paper, and wherein the infusion substance comprises at least one flavoring component.
