PB69 PolyBak backer is a .020 inch thick sheet measuring 37 x 145 inch, so it covers large panel faces in a single run and keeps seams out of the field on typical casework or fixture components. This PB69BR28 3X12 sheet is part of the Richwood Industries backers line, giving a consistent product identity that supports repeat ordering across projects. The PB69 PolyBak backer has just the right mix of performance and economy, so it fits value-driven jobs where panel stability still matters. Being 2.5 times stronger than the leading saturated Kraft paper backer of the same thickness, this sheet maintains integrity when panels are machined, handled, or transported. That strength supports cleaner edges during sizing and reduces the chance of the backer tearing as parts move through the shop.
This PB69 PolyBak .020 inch backer is most commonly used as a backer for laminated substrates, so it pairs with decorative faces to balance the panel during fabrication and install. When used on the reverse side of a panel, the 37 x 145 inch format lets fabricators handle large components without piecing together small strips, which streamlines layout and bonding steps. PB69 is also used as a paintable overlay for substrates and columns, giving a uniform surface that can be coated as part of a finishing schedule. That paintable overlay role supports column wraps or similar elements where a consistent base layer helps coatings lay down more evenly.
PB69 PolyBak backer is most commonly used as a backer for laminated substrates, so it sits opposite a decorative face to create a balanced construction on cabinet parts, fixtures, or other panel-based components. Because this sheet is 2.5 times stronger than the leading saturated Kraft paper backer of the same thickness, it helps the back side of the panel stand up to routing, drilling, and handling while the decorative face is being processed. The .020 inch thickness keeps the backer light, so it supports the laminate without adding excessive build that could affect edge treatments or clearances in assemblies using multiple panels. With its 37 x 145 inch dimensions, the sheet covers long or tall workpieces, which helps maintain a single, continuous backing layer behind large laminate faces in one press cycle.
The fact that PB69 is our most popular PolyBak backer reflects that shops repeatedly use this construction on their laminated substrates, creating predictable behavior from job to job when balancing panels. Being 2.5 times stronger than the leading saturated Kraft paper backer of the same thickness means the backer better resists tearing or breaking when panels are cut to size, so edges stay clean as parts move through saws or CNC equipment. When the same PB69 PolyBak backer is used as a paintable overlay for substrates and columns, its strength supports handling during finishing and installation, which is important when wrapped elements are moved into place. The large 37 x 145 inch sheet size allows multiple narrow parts or one oversized component to be nested on a single backer, supporting efficient yield planning around standard casework and column dimensions.
The PB69 PolyBak backer sheet is 37 x 145 inch, so it can cover large panels or multiple smaller parts on one sheet for efficient cutting layouts.
The PB69 PolyBak backer is .020 inch thick, providing a light balancing layer that supports laminated substrates without adding significant buildup to panel thickness.
PB69 PolyBak is most commonly used as a backer for laminated substrates, balancing the decorative face and supporting machining and handling of panels.
This PB69 PolyBak backer is also used as a paintable overlay for substrates and columns, giving a consistent base surface for coating systems.
PB69 PolyBak backer is 2.5 times stronger than the leading saturated Kraft paper backer of the same thickness, so it better resists tearing during cutting and handling.
PB69BR28 3X12 is the manufacturer part number for this .020 inch, 37 x 145 inch PB69 PolyBak backer, helping match this exact sheet on future orders.
Choose the PB69 PolyBak .020 inch, 37 x 145 inch backer when a laminated substrate or paintable overlay needs both economy and strength in one sheet. This PB69BR28 3X12 backer from Richwood Industries supports balanced construction on laminated substrates and paintable column wraps. By using a backer that is 2.5 times stronger than the leading saturated Kraft paper backer of the same thickness, panel backs stay more stable through cutting, routing, and installation steps across a project.
