Abstract:
Provided are a packaging sheet and a packaging container where it is unnecessary to paste a printed label and disappearance or color development due to friction or the like after thermal printing do not occur. The packaging sheet includes a heat seal layer  10  for thermally welding by heating, a heat-sensitive layer  40  including a color developing material that develops a color by heating, and a base material layer  70  that secures the strength and protects the heat-sensitive layer  40 . The heat seal layer  10 , the heat-sensitive layer  40 , and the base material layer  70  are provided in this order from a back surface side in a thickness direction. The packaging sheet is transparent before the heat-sensitive layer  40  develops the color.

Claim (Index 12):
A packaging method for packaging contents with the packaging sheet according to  claim 1 , the packaging method comprising:\n a bending step of bending the packaging sheet with a rectangular or band-like shape into a cylindrical shape; an axial-direction welding part formation step of forming an axial-direction welding part that extends in an axial direction by thermally welding the heat seal layer on one end of the packaging sheet that is bent the cylindrical shape and the heat seal layer on the other end, the heat seal layers facing each other in a direction orthogonal to an axis of the cylindrical part; an end welding part formation step of forming an end welding part that extends in the direction orthogonal to the axis by thermally welding to each other the heat seal layers on an end in the axial direction of the packaging sheet bent into the cylindrical shape; and a thermal printing step of thermally printing by heating a part of the heat-sensitive layer so as to develop the color.
