Abstract
The present invention provides a biodegradable extruded netting. The netting comprises a plurality of interconnected strands with at least some of the strands comprising a biodegradable composition comprising polylactic acid polymer and biodegradable plasticizer. In at least one embodiment, at least 10% of the strands are made of the biodegradable composition. The present invention also relates to a method for making biodegradable extruded netting. The method comprises extruding strands of polymeric material to form a netting wherein at least some of the strands are formed of the biodegradable composition.
Claims25
A biodegradable extruded netting, said netting comprising a plurality of oriented interconnected extruded strands that intersect during extrusion, at least some of the strands comprising a biodegradable composition comprising polylactic acid polymer and biodegradable plasticizer.
A biodegradable extruded netting, said netting comprising a plurality of interconnected extruded strands that intersect during extrusion, at least some of the strands comprising a biodegradable composition having a tensile modulus of 200,000 to 440,000 psi and comprising 5 to 95 weight percent polylactic acid polymer and 5 to 95 weight percent biodegradable aliphatic-aromatic copolyester plasticizer, when the polymer has a tensile modulus of 475,000 to 750,000 psi and the plasticizer has a tensile modulus of 1,000 to 75,000 psi.
