Abstract:
Disclosed is a biodegradable sheet comprising at least one layer which comprises a biodegradable polymer and surface treated nanoclay particles or at least one layer which comprises PVOH grafted with a crosslinker and PBS or PBSA or a combination a biodegradable polymer and surface treated nanoclay particles and at least one layer which comprises PVOH grafted with a crosslinker and PBS or PBSA.
Abstract:
The present invention is directed to biodegradable sheets, and in particular to biodegradable sheets including a polymer layer comprising from about 70 to about 90% (w/w) PBSA and from about 10 to about 30% (w/w) PLA, either in an inner layer, or in an outer layer wherein, if in the outer layer the sheet includes an inner layer comprising PBAT.
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 (PBS A), poly lactic acid (PL A), 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 PBS A The biodegradable sheet may further include at least one metalized, biodegradable, laminate layer.
