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 biodegradable sheet prepared from biodegradable material, a process for preparing the biodegradable sheet and uses thereof. One of the disclosed uses of the biodegradable sheet is in the preparation of a flexible liquid receptacle. Disclosed also is a flexible liquid receptacle arranged as an array of several receptacle units that are attached to one another and that may be detached from one another by tearing along a perforated line created between each two receptacle units. The disclosed array may also include a hanger, thus allowing the array to be hung from any appropriate means. Further disclosed is a biodegradable sheet including at least one layer comprising about 15-25% w/w PLA and about 75-85% w/w PBSA.
