Degradable extrusion webs made from polymer blend compositions

Abstract

The present disclosure relates to a degradable extruded web comprising a plurality of interconnected strands, at least a portion of the strands being made from a polymer blend comprising a polylactic acid polymer composition, a polybutylene succinate, and a degradation additive comprising a degradation agent in a carrier resin. The present disclosure also relates to turf and methods of making turf using such degradable extrusion webs.

Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] This application claims the benefit of US Provisional Application No. 62 / 860,931, filed June 13, 2019, the entire disclosure of which is incorporated herein by reference for all purposes. Background technique [0003] The field of the present disclosure relates to extruded plastic meshes, and more particularly, to a degradable extruded mesh comprising a plurality of interconnected strands for use with turf. [0004] In the traditional method of growing turf, grass seeds are planted in the soil. After the forage crop is planted until the roots are sufficiently intertwined that the turf sticks together like a sticky carpet-like mat when cut, the turf can be peeled or rolled out of the underlying soil and removed. Typically, the soil layer includes a synthetic structure, such as a net, to help keep the turf intact and coherent after harvest. [0005] Extruded plastic netting is used in many commercial applications such as ...
