PolyBak PB90 veneer backer is a brown sheet backer that is most commonly used as a backer for laminated substrates, so it supports decorative faces in panel construction. With a nominal thickness of .024 inch, this sheet matches common thin backer applications, which helps panels stay balanced without adding bulk in build-ups or edge treatments. The 49 inch by 97 inch size works with many panel layouts that follow a 4 foot by 8 foot format, so it helps minimize trimming on standard cabinet or fixture components. As part of the Richwood Industries backers line, this backer fits projects that call for a consistent back-side layer behind high-pressure laminate or similar surfacing, supporting stable assemblies on shop equipment.
This PolyBak PB90 veneer backer at .024 inch thickness works as a dedicated backer for laminated substrates, so it fits into layup stacks where a balancing layer is required behind a decorative face. The 49 inch by 97 inch sheet size aligns with common press bed and panel dimensions, which simplifies cutting sequences for casework, millwork, and fixture shops. When used as a paintable overlay for substrates and columns, the advanced performance level supports a smooth, stable base layer that can be finished after pressing, aiding in consistent results along tall vertical pieces. As a backer within the Richwood Industries backers category, it integrates into workflows that rely on matched components from a single product class.
PolyBak PB90 veneer backer is most commonly used as a backer for laminated substrates, so it serves as the balancing layer behind decorative laminate or surfacing on panels. This role supports panel flatness from press to installation on cabinet runs, partitions, or fixtures. It is also used as a paintable overlay for substrates and columns, which means it can form the prepared surface over core materials before finishing tall or visible surfaces. Because this sheet carries an advanced performance level, it is designed to handle demanding applications where standard saturated Kraft paper backers of similar thickness are used. At 3.5 times stronger than the leading saturated Kraft paper backer of the same thickness, Poly br Bak PB90 adds strength to the back side of the assembly, which matters when panels are handled repeatedly, notched, or machined for hardware and openings.
The nominal thickness of .024 inch sets a controlled layer in the panel stack-up, which supports predictable balancing on both faces of laminated substrates. This consistent thickness helps maintain alignment in dadoes, grooves, and other joinery that expect a stable overall panel dimension. The 49 inch width and 97 inch length work with layouts based on standard 4 foot by 8 foot sheets, giving fabricators a familiar starting size for ripping and crosscutting. That format helps maintain repeatable cut patterns across multiple sheets, which can reduce layout variation between identical case parts. The brown color keeps the back-side appearance uniform on interior faces or hidden surfaces, supporting a professional look where the backing is visible in cabinets or column wraps. Identified by manufacturer part number PB90BR28 4X8 within the Richwood Industries backers product class, this sheet aligns directly with ordering, reordering, and matching inventory for ongoing work.
PolyBak PB90 veneer backer is most commonly used as a backer for laminated substrates, so it serves as the balancing layer behind decorative laminate panels in cabinet, millwork, and fixture production.
Poly br Bak PB90 is 3.5 times stronger than the leading saturated Kraft paper backer of the same thickness, which supports panels during handling, machining, and service where higher backer strength is needed.
The .024 inch nominal thickness gives a thin yet structural backer layer, which helps keep laminated panels balanced without significantly changing total panel thickness at edges or joints.
The 49 by 97 inch size aligns with common 4 by 8 panel formats, which supports efficient ripping and crosscutting patterns for cabinet parts and full-height panels on typical shop equipment.
PolyBak PB90 veneer backer is also used as a paintable overlay for substrates and columns, so it can provide a prepared surface layer before finishing tall or visible components.
The PB90BR28 4X8 manufacturer part number identifies this PolyBak PB90 veneer backer as a 49 inch by 97 inch brown sheet within the Richwood Industries backers product class.
PolyBak PB90 veneer backer in the 49 inch by 97 inch, .024 inch nominal thickness format provides an advanced performance backer for laminated substrates and paintable overlays. Its strength rating at 3.5 times that of a leading saturated Kraft paper backer of the same thickness supports demanding handling and machining. The brown color and standard panel dimensions pair well with many casework and column layouts. For work that calls for a consistent, advanced performance backer or overlay, this Richwood Industries backer aligns with laminated panel and column applications.
