Abstract: The present invention relates to a multilayer structure, such as a film or a sheet, and articles made from such multilayer structures. The present invention provides a multilayer structure comprising at least three different layers A, B and C, wherein said layer B is disposed between said layer A and said layer C and is capable of binding said layer A to said layer C, wherein layer A comprises a polylactide (PLA) polymer, layer B comprises a lactide-rich poly(lactide-co-glycolide) (PLGA) polymer, and layer C comprises a polyglycolide (PGA) polymer and/or a glycolide-rich poly(lactide-co-glycolide) (PLGA) polymer. The present invention also provides a multilayer structure comprising at least one barrier layer, providing gas barrier properties, wherein said barrier layer comprises a glycolide-rich poly(lactide-co-glycolide) (PLGA) polymer.

Abstract: A method for producing a polylactic acid (PLA) shaped article by thermoforming and thermoformed PLA articles. The method for producing a shaped article includes: heating a sheet of crystallizable polylactic acid (PLA)-based resin having a ratio of cold crystallization over total melting enthalpy (?Hcc/?Hm) greater than 0.70 as determined by differential scanning calorimetry (DSC), wherein heating includes a heating step the sheet is heated from a surface temperature of at most 80° C. to a surface temperature of at least 90° C. to at most 150° C. at heating rate of 5° C. to 25° C. per second, to provide heated sheet having a ratio of cold crystallization over total melting enthalpy (?Hcc/?Hm) greater than 0.5 as determined by DSC; and immediately after heating, forming heated sheet to provide a shaped article by means of a mold having a temperature of at least 70° C. and at most 120° C.

Abstract: This invention relates to labels, particularly removable polymeric labels for use on reusable containers. The labels contain at least two polymeric layers having different coefficients of linear thermal expansion, such that, upon exposure to elevated temperatures, the label is reversibly curled.
