The compostable multilayer membrane may have an Oxygen Transfer Rate (OTR) value lower than 0.5 cc/m.sup.2/day/atm. The filter may be adjacent to the second barrier layer on a side opposite to the intermediate layer.

PRESSURE-SENSITIVE ADHESIVE SHEET
20210292611 · 2021-09-23 · ·

Provided is a PSA sheet capable of suitably preventing bubble formation caused by outgassing. This invention provides a PSA sheet comprising a PSA layer that forms an adhesive face. In an aging test where the adhesive face is press-bonded to a glass plate and stored at 50° C. for 24 hours, the PSA sheet has at least 5% post-aging non-bonding area Sa, with Sa defined as the ratio of all areas non-bonding to the glass plate relative to the total area of the adhesive face. The non-bonding areas have parts linearly extending along the adhesive face.

Fabric print medium

A fabric print medium containing a fabric base substrate with a first and a second side; a polymeric barrier layer that is extruded, or a polymeric barrier layer with adhesion property that is laminated, on at least one side of the fabric base substrate; a primary coating composition that includes a polymeric binder and filler particles applied over a polymeric barrier layer; and an image-receiving coating composition that includes, at least, a first crosslinked polymeric network and a second crosslinked polymeric network, that is applied over the primary coating composition. Also disclosed are the method for making such fabric print medium and the method for producing printed images using said material.

PROCESS FOR MANUFACTURING SCRUBBY SUBSTRATES AND SUBSTRATES MADE THEREFROM
20210205959 · 2021-07-08 ·

In-line processes for producing scrubby substrates, and related scrubby substrate cleaning articles. The process may include melting a polymer resin material, and extruding or otherwise dispensing the molten polymer resin material through one or more orifices of a heated nozzle, into a stream of hot inert gas, which attenuates the molten resin, so that the resin forms into elongated globules (rather than fibers or filaments). Such globules may have irregular cross-section and/or irregular thickness along a length of the globules. Alternatively, the molten resin may be formed into substantially continuous or discontinuous string or chain pattern of abrasive fibers, exhibiting a high frequency, low amplitude substantially linear pattern on the base substrate. In either case the globules or abrasive fibers are collected onto at least a portion of a base substrate layer to form a scrubby substrate that is more abrasive than typical meltblown materials.

Bonded Laminate Including a Formed Nonwoven Substrate

Bonded formed laminates, and methods for making bonded formed laminates, are made from multiple layers of formed substrates comprising at least one nonwoven formed substrate which are bonded together at the distal ends or bases of protrusions formed in the substrates. The bonded formed laminate provides a very soft and lofty structure that is sustainable under compression.
