Abstract
Official abstract text for this publication.
There is provided an in-mold label that is easily peeled from a resin container during recycling. The in-mold label has an absolute value of an area dimension change rate of 1% or less at 80° C. and a tack force of 0.8 N/cm 2 or less at 80° C. The in-mold label can be adhered to a resin container that is a stretch blow-molded body.
First claim
Opening claim text (preview).
The invention claimed is: 1. An in-mold label for being adhered to a resin container that is a stretch blow-molded body, the in-mold label having an absolute value of an area dimension change rate of 1% or less at 80° C. and a tack force of 0.8 N/cm 2 or less at 80° C. 2. The in-mold label according to claim 1 , having a tack force of 1 N/cm 2 or less at 90° C. 3. The in-mold label according to claim 1 , comprising: a heat sealing layer that adheres to the resin container, wherein the heat sealing layer contains a thermoplastic resin having a melting point of 90 to 110° C. 4. The in-mold label according to claim 3 , wherein the heat sealing layer comprises a first heat sealing layer, and a second heat sealing layer that adheres to the resin container, and the first heat sealing layer contains a nonpolar resin having a melting point of 90 to 110° C. 5. The in-mold label according to claim 3 , wherein the heat sealing layer comprises a first heat sealing layer, and a second heat sealing layer that adheres to the resin container, and the second heat sealing layer contains a polar resin having a melting point of 90 to 110° C. 6. The in-mold label according to claim 1 , comprising: a heat sealing layer that adheres to the resin container, wherein a fusion rate of the heat sealing layer at 80° C. is 75% or less, and a fusion rate of the heat sealing layer at 100° C. is 70% or more. 7. A labeled container comprising: a resin container that is a stretch blow-molded body; and an in-mold label adhering to a surface of the resin container, wherein an absolute value of an area dimension change rate of the in-mold label at 80° C. is 1% or less, and a tack force of the in-mold label at 80° C. is 0.8 N/cm 2 or less. 8. The labeled container according to claim 7 , wherein an absolute value of an area dimension change rate of the resin container at 80° C. is 4% or more. 9. The labeled container according to claim 7 , wherein the in-mold label has a tack force of 1 N/cm2 or less at 90° C. 10. The labeled container according to claim 7 , wherein the in-mold label comprises a heat sealing layer that adheres to the resin container, and the heat sealing layer contains a thermoplastic resin having a melting point of 90 to 110° C. 11. The labeled container according to claim 7 , wherein the in-mold label comprises a heat sealing layer that adheres to the resin container, and a fusion rate of the heat sealing layer at 80° C. is 75% or less, and a fusion rate of the heat sealing layer at 100° C. is 70% or more. 12. The labeled container according to claim 11 , wherein the heat sealing layer comprises a first heat sealing layer, and a second heat sealing layer that adheres to the resin container, and the first heat sealing layer contains a nonpolar resin having a melting point of 90 to 110° C. 13. The labeled container according to claim 11 , wherein the heat sealing layer comprises a first heat sealing layer, and a second heat sealing layer that adheres to the resin container, and the second heat sealing layer contains a polar resin having a melting point of 90 to 110° C. 14. The labeled container according to claim 7 , wherein the in-mold label comprises a substrate layer, and the substrate layer contains a propylene-based resin and an ethylene-based resin.
