    Abstract: Disclosed is a biodegradable sheet comprising at least one layer which is a direct contact layer, intended to successfully contact materials, such as liquids, while maintaining the mechanical properties of the sheet and to extend the biodegradable sheet shelf life. The direct contact layer may comprise a hydrophobic polymer selected from poly(epsilon-caprolactone) (PCL) polyhydroxybutyrate (PHB), Polydioxanone (PDO) polyglycolic acid (PGA), polybutylene succinate (PBS), polybutylene succinate adipate (PBSA), poly lactic acid (PLA), polybutylene adipate terphtalate (PBAT), polyhydroxyalkanoates (PHA), such as polyhydroxybutyrates (PHB), polyhydroxyvalerates (PHV), and polyhydroxybutyrate-hydroxyvalerate copolymers (PHBV) or any mixture thereof. The biodegradable sheet may further comprise surface treated nanoclay particles, PVOH grafted with a crosslinker and PBS or PBSA The first hydrophobic polymer is present in said at least one layer in an amount of about 30% w/w.

    Abstract: Disclosed is a multilayered biodegradable sheet comprising at least one layer which comprises a biodegradable polymer and surface treated nanoclay particles, comprising a bridge between the surface treated nanoclay particles and the biodegradable polymer, the bridge comprising a functional moiety having at least two functional sites, one of which is conjugated to the nanoclay particle surface and another of which is conjugated to the biodegradable polymer. Also disclosed is a multilayered biodegradable sheet comprising at least one layer which comprises polyvinyl alcohol (PVOH) grafted with a crosslinker and polybutylene succinate (PBS) or polybutylene succinate adipate (PBSA).
