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:
Disclosed is a biodegradable sheet prepared from biodegradable material comprising a gas barrier material, wherein the gas barrier material may be a nanoclay and/or polyvinyl alcohol.
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.
Abstract:
A single-layered biodegradable sheet comprising polylactic acid (PLA) and polybutylene succinate (PBS), at a w/w ratio of about 20% w/w PLA to about 80% w/w PBS, a process for preparing the biodegradable sheet, and uses thereof.
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:
The present invention relates to a biodegradable sheet comprising at least two polymer layers, wherein a first polymer layer comprises a mixture of at least two different biodegradable polymers selected from the group consisting of PLA, PCL, PBS and PBSA; and wherein a second polymer layer comprises a biodegradable polymer selected from the group consisting of PBS, PBSA, a mixture of PLA and PBS, and a mixture of PLA and PBSA.
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).
