  • Biodegradable netting
    Patent number: 7326659
    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.

  • Extruded netting exhibiting stretch and bonding
    Patent number: 6692606
    Abstract: Extruded net with at least some strands which melt away upon the application of heat while other strands maintain elastic, or other desirable, properties. This netting is advantageously combined with a fabric in which the low melting strands function as an adhesive, while the high melting strands maintain their designed properties in the final laminate product.

  • Bicomponent elastomeric netting
    Patent number: 6391420
    Abstract: The invention is an extruded bicomponent elastomeric netting having unidirectional elasticity. Such a netting product is a non-woven article employing a non-elastic material such as polypropylene (10) in the machine direction strands and an elastic material such as a styrenic block copolymer (12) in the cross machine direction strands. The reverse arrangement, a product with “reverse strand distribution”, is also possible.
