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.
