A method of recycling laminated fabrics and laminated fabric products and producing new laminated fabrics and laminated fabric products includes the steps of shredding scrap or used laminated fabric material, melt separating the polymers, pelletizing the melt separated polymers, extruding the pelletized material with at least one virgin material to form a film, and laminating the film to a nonwoven material to form a new laminated fabric. The scrap or recycled laminated fabric products can include plastic/polymer materials having different melting temperatures. The new laminated fabric can be utilized to produce new products, such as protective covers.

HIGH-SHRINK, HIGH-STRENGTH MULTILAYER FILM
20210101374 · 2021-04-08 ·

A multilayer, heat-shrinkable film has a first portion containing an outer heat seal layer and a second portion containing a PVDC barrier layer and a second outer layer comprising polyester. Both film portions comprise polymer networks which are strained by solid-state orientation, but only the first portion contains a crosslinked polymer network. The film has (i) a total free shrink at 85° C. of at least 90% and (ii) an instrumented impact energy-to-break of at least 0.0.65 J/mil and/or an instrumented impact peak load of at least 70 N/mil. The film is primarily made from ethylene-based polymers. Packaging articles can be made by sealing the film to itself. The film comprises no polyamide or polyamide in an amount up to 10 wt %, on a total film weight basis.

BALANCING FLOORING TILE UPCURL BY REVERSE SHRINKAGE

A shrinkable material is attached to the backside of a floorcovering tile and allowed to shrink to a controlled extent to produce a backside shrinking that counteracts the tendency of the tile to warp out of plane on the floor as temperature and humidity vary during installation or while in use. The tile assumes a slightly convex shape in one or two directions that can be overcome as it is adhesively attached to the floor. The added material may also serve a secondary function as pressure sensitive adhesive, a friction layer, a fluid barrier, or a cushioning surface.
