Claims18
A tobacco product packaging material, the packaging material being a sheet-packaging material for packaging a tobacco product, the packaging material at least comprising:
- a paper layer containing a flavoring component;
- and
- a barrier layer having barrier properties against the flavoring component,
- wherein the barrier layer is a non-metal layer, and
- wherein the barrier layer satisfies (Condition 1) below:
- (Condition 1) operations (1) to (4) below using the barrier layer are performed five times, and permeation of ethanol is not visually observed in any of resulting five specimens,
- (1) a specimen in which the barrier layer is disposed on a substrate is prepared,
- (2) the specimen is placed on a flat surface such that the barrier layer faces upward,
- (3) three drops of ethanol (purity:
- 99.5% or more) are dropped from a height of 25 mm onto the barrier layer with a pipette, and
- (4) ten minutes later, the ethanol adhering to the barrier layer is wiped off with tissue paper.
