Biodegradable panels
The present invention relates to panels. The panels include a panel layer and a printed layer formed on the panel layer. The panel layer includes a polylactic acid (PLA) resin. The panels are environmentally friendly and biodegradable.
1. A biodegradable panel, comprising:
a panel layer; and
a printed layer disposed on the panel layer,
wherein the panel layer comprises a polylactic acid (PLA) resin
a plasticizer; and
a cross-linking agent, wherein the polylactic acid (PLA) resin is only an amorphous polylactic acid (a-PLA) and,
wherein the panel layer comprises 0.1 to 5.0 parts by weight of the cross-linking agent based on 100 parts by weight of the PLA resin.
2. The biodegradable panel according to claim 1 , wherein the panel layer comprises a blended resin of the PLA resin and a bioresin.
3. The biodegradable panel according to claim 1 , wherein the panel layer comprises a blended resin of the PLA resin and a synthetic resin.
4. The biodegradable panel according to claim 1 , wherein the panel layer further comprises a reinforcing agent.
5. The biodegradable panel according to claim 2 , wherein the blended resin comprises 10 to 70 parts by weight of the bioresin, based on 100 parts by weight of the PLA resin.
6. The biodegradable panel according to claim 3 , wherein the blended resin comprises 10 to 70 parts by weight of the synthetic resin, based on 100 parts by weight of the PLA resin.
7. A biodegradable panel, comprising:
a base layer;
a panel layer disposed on the base layer;
a printed layer disposed on the panel layer; and
a transparent layer disposed on the printed layer,
wherein each of the panel layer and the transparent layer comprises a polylactic acid (PLA) resin and a cross-linking agent,
wherein the panel layer comprises 0.1 to 5.0 parts by weight of the cross-linking agent based on 100 parts by weight of the PLA resin, and
wherein the transparent layer comprises 0.01 to 10 parts by weight of the cross-linking agent based on 100 parts by weight of the PLA resin.
8. The biodegradable panel according to claim 7 , wherein each of the panel layer and the transparent layer comprises a blended resin of the PLA resin and a bioresin.
9. The biodegradable panel according to claim 7 , wherein each of the panel layer and the transparent layer comprises a blended resin of the PLA resin and a synthetic resin.
10. The biodegradable panel according to claim 7 , wherein the panel layer further comprises a reinforcing agent.
11. The biodegradable panel according to claim 7 , wherein the transparent layer further comprises a plasticizer, a processing aid, or a mixture thereof.
12. The biodegradable panel according to claim 7 , wherein the transparent layer further comprises a lubricant, an anti-hydrolysis agent, or a mixture thereof.
13. The biodegradable panel according to claim 8 , wherein the blended resin comprises 10 to 70 parts by weight of the bioresin, based on 100 parts by weight of the PLA resin.
14. The biodegradable panel according to claim 8 , wherein the blended resin comprises 10 to 70 parts by weight of the synthetic resin, based on 100 parts by weight of the PLA resin.
