Abstract
Claims
1. A laminating material that is attached to an adhesive label attached to a substrate, It comprises a base material and an adhesive layer, A laminate material characterized in that the base material is made of the same type of resin material as the resin material constituting the adherend.
2. The laminate material according to claim 1, wherein the adherend and the substrate are composed of a polyolefin-based resin material.
3. The laminate material according to claim 1, wherein the thickness of the substrate is 10 μm or more and 50 μm or less.
4. The laminate material according to claim 1 or 2, wherein the adhesive layer is made of a material containing an acrylic adhesive.
5. The invention comprises an adhesive sheet for labels used in the manufacture of adhesive labels to be attached to an object, and a laminating material to be attached to the adhesive label, The adhesive sheet for labels comprises a label substrate and an adhesive layer for labels disposed on one side of the label substrate. The laminate material comprises a base material and an adhesive layer. An adhesive label-laminating material set characterized in that the base material is made of the same type of resin material as the resin material constituting the adherend.
6. The adhesive label-laminating material set according to claim 5, wherein the adhesive layer for the label is a wash-off type adhesive layer.
7. The adhesive sheet for labels further has a label release coating layer on the side of the label substrate opposite to the side facing the adhesive layer for labels. The adhesive label-laminating material set according to claim 5, wherein the label substrate and the label adhesive layer are made of the same type of resin material as the resin material constituting the adherend.
8. It comprises a substrate, an adhesive label attached to the substrate, and a laminate material attached to the adhesive label. The adhesive label comprises a label substrate, an adhesive layer for labels disposed on one side of the label substrate, and a printing layer disposed on the other side of the label substrate. The adhesive layer for the label is in contact with the adherend. The laminate material comprises a base material and an adhesive layer. The adhesive layer is in contact with the printed layer, The adhesive is characterized in that the base material is made of the same type of resin material as the resin material constituting the adherend.
9. A recovery method characterized by applying a liquid to the adhesive according to claim 8, thereby separating and recovering at least the portion of the adhesive that includes the printed layer.
10. The recovery method according to claim 9, wherein the liquid is an alkaline liquid.
11. The recovery method according to claim 9 or 10, wherein the adhesive layer for the label is a wash-off type adhesive layer.
12. The adhesive label further has a label release coating layer on the side of the label substrate opposite to the side facing the label adhesive layer. The label substrate and the label adhesive layer are made of the same type of resin material as the resin material constituting the adherend. The recovery method according to claim 9 or 10, wherein the adherend to which the label substrate is bonded via the label adhesive layer is separated from the portion including the printing layer and recovered.
