Abstract
Degradable extruded nettings are provided. Degradable extruded nettings may include a plurality of interconnected strands, at least some of the strands being made from a polymeric blend, the polymeric blend including a polylactic acid polymer composition, polybutylene succinate, and a degradation additive, the degradation additive including a degrader in a carrier resin are provided. Grass sod and methods for preparing grass sod using such degradable extruded nettings are also provided.
Claims18
A polymeric blend composition suitable for preparing a degradable extruded netting, the polymeric blend composition comprising:
- a polylactic acid composition in an amount ranging from about 55% to about 60% by weight;
- a polybutyrate composition in an amount ranging from about 35% to about 40% by weight;
- a compatibilizer composition in an amount ranging from about 0.5% to about 3% by weight;
- and
- a degradation additive in an amount ranging from about 2% to about 7% by weight, wherein the degradation additive comprises iron stearate and manganese stearate in a carrier resin.
A polymeric blend composition suitable for preparing a degradable extruded netting, the polymeric blend composition comprising:
- a polylactic acid composition in an amount ranging from about 55% to about 60% by weight;
- a polybutyrate composition in an amount ranging from about 35% to about 40% by weight;
- and
- a degradation additive in an amount ranging from about 2% to about 7% by weight, wherein the degradation additive comprises iron stearate and manganese stearate in a carrier resin.
Grass sod comprising:
- grass grown in soil;
- and
- degradable extruded netting in the soil, the degradable extruded netting including:
- a plurality of interconnected strands, at least one of the plurality of interconnected strands being made from a polymeric blend, the polymeric blend comprising:
- a polylactic acid composition in an amount ranging from about 55% to about 60% by weight;
- a polybutyrate composition in an amount ranging from about 35% to about 40% by weight;
- and
- a degradation additive in an amount ranging from about 2% to about 7% by weight, wherein the degradation additive comprises iron stearate and manganese stearate in a carrier resin.
