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.

Abstract: There is provided a transparent adhesive sheet on which printing can be performed during in use and which has high transparency, while including an adhesive layer on the back surface side and a release layer on the front surface side. The transparent adhesive sheet includes: a base material layer formed with a transparent material; an adhesive layer formed on the back surface side of the base material layer and formed with an adhesive agent for bonding to an adherend; a recording layer formed on the front surface side of the base material layer and containing a color developing material that thermally develops color; and a release layer formed on the further front surface side of the recording layer and having release properties to the adhesive agent. The transparent adhesive sheet is transparent in the state before the recording layer develops color.
