Light-selective mulch

Lignin formulations for making light-selective mulch, methods of making such lignin formulations, light-selective mulches comprising substrates treated with lignin formulations, and methods of making such light-selective mulches. Some methods involve preparing aqueous lignin formulations that can be used as coatings that, in turn, can be applied to a substrate, such as a paper web, to form a biodegradable, light-selective mulch. Some such mulches blocks at least some light in the ultraviolet and blue/green ranges (350 nm to 500 nm) of the visible light spectrum to inhibit weed growth below the mulch, while also transmitting light in the red/infrared ranges to heat the soil below the mulch.

Creped single ply tissue

Provided are tissue products comprising a single ply tissue web that has been prepared by a creping process and more preferably by a print creping process adapted to dispose a non-crosslinked latex polymer on at least one of the outer surfaces of the tissue web. The creped single ply tissue products generally have a low degree of stiffness, such as a Stiffness Index less than about 8.00, and are highly durable, such as a Durability Index greater than about 12.0. In other instances, the tissue products may have very low levels of lint or dust, such as a Slough less than about 4.00 mg, even at basis weights from about 45 to about 55 grams per square meter (gsm) and tensile strengths from 600 to 1,200 g/3″.
