Research on Poly Lactic Acid Solvent Coated Paper

This paper draws on a roll coating method which used for the production of coated paper. Polylactide coating cardboard was prepared through the solvent coating, and study its packaging performance. In this study, chloroform is based solvent, ethanol or n-propanol as auxiliary solvents, poly (ethylene glycol) or poly caprolactone as plasticizer, and the water vapor permeability, oxygen permeability and heat sealability of polylactic acid coated cardboard.
