    Description

    PolyBak PB90 Veneer Backer For Laminated Panels

    PolyBak PB90 veneer backer is a .024 inch thick sheet designed as a backer for laminated substrates, so it supports decorative faces with a stable balancing layer that helps panels perform consistently in service. This Richwood Industries backer in a 49 inch by 121 inch size covers common sheet layouts, so installers and fabricators can work full panels with fewer seams to plan around. The material is 3.5 times stronger than the leading saturated Kraft paper backer of the same thickness, which means it resists handling damage and stresses during fabrication better than standard paper options. Its brown color provides a neutral, uniform back side appearance on casework and fixtures, which is useful wherever the back of the panel may be visible. As part of the Richwood Industries backers line, this sheet is built for use behind laminates in woodworking and interior construction.

    Key PolyBak PB90 Details For Real-World Jobs

    • The nominal .024 inch thickness creates a predictable balancing layer behind laminates, helping panel builders maintain even construction when matching decorative faces on cabinets and fixtures.
    • The 49 inch width works with standard panel widths, so shops can lay up full-size sheets efficiently and reduce trimming waste on production runs.
    • The 121 inch length extends coverage for tall panels and fixtures, allowing long cabinet sides or columns to be faced in one section instead of breaking the run.
    • Being 3.5 times stronger than leading saturated Kraft paper backer of the same thickness, the sheet tolerates handling and lamination pressure without tearing easily, which supports smoother processing.
    • The brown color gives the back of laminated substrates a consistent appearance, which is useful when building open cabinets, shelving, or casework that exposes non-show faces.
    • Availability in 1,800 lineal foot rolls means shops with higher volume needs can work from continuous stock, helping maintain consistent material from job to job.

    Using PolyBak PB90 For Backing And Overlay Work

    This PolyBak PB90 sheet is most commonly used as a backer for laminated substrates, so it serves as the balancing layer behind decorative laminate or similar surfacing on cabinet components and interior fixtures. Because the sheet is designed as a backer, it supports panel construction where both dimensional stability and a consistent back side face are important to the finished job. The product is also used as a paintable overlay for substrates and columns, giving fabricators a uniform surface on which to apply coatings when building column wraps, soffits, or similar architectural elements. With a nominal thickness of .024 inch and the 49 inch by 121 inch format, the sheet matches many common panel layouts, which helps streamline layout and cutting during fabrication and installation.

    Applying This Richwood PolyBak Backer On Projects

    Backer Sheet Performance On Laminated Substrates

    PolyBak PB90 is most commonly used as a backer for laminated substrates, so it plays the role of the balancing sheet behind decorative laminate faces on furniture, cabinetry, and fixtures. The nominal .024 inch thickness provides a defined layer that complements the face material, supporting even panel build-up for casework in kitchens, offices, and commercial spaces. Because this backer is 3.5 times stronger than the leading saturated Kraft paper backer of the same thickness, it handles the stresses of lamination, trimming, and machining with more resistance to tearing during production. That higher strength helps panels stay intact while moving through presses, saws, and routers on busy shop floors.

    The brown color of this backer establishes a uniform back side tone for shelves, partitions, and cabinet ends where the rear face may be partially visible, supporting consistent visual results on open or glass-front units. Its 49 inch width and 121 inch length correspond to common sheet dimensions, which lets fabricators cover large surfaces in one piece on many jobs. In practice, this reduces seams on back faces and simplifies layout for tall sides or dividers in closets and casework. With availability in 1,800 lineal foot rolls, higher volume operations can run repeated panels with the same backer stock, maintaining continuity across multiple rooms or projects.

    Paintable Overlay Use For Substrates And Columns

    PolyBak PB90 is also used as a paintable overlay for substrates and columns, so it can act as the facing surface when constructing column wraps, valances, or other architectural elements that will receive paint. The nominal .024 inch thickness gives the overlay enough body to create a consistent face over the substrate, which supports a smoother coated appearance once painted. Because the sheet is 3.5 times stronger than comparable saturated Kraft paper backer at the same thickness, it stands up to handling and forming around structural elements with reduced risk of tearing during fabrication.

    The 49 inch by 121 inch size suits many column and wall applications, making it easier to span larger surfaces with fewer joints in lobbies, corridors, or similar spaces where long runs are common. Its brown color creates a predictable base tone beneath paint systems, which helps finish shops anticipate coverage when building interior components. With the option to source this material in 1,800 lineal foot rolls, fabricators working on multi-column or repeated element projects can draw from continuous stock, aiding consistency across every wrapped substrate and column on the job.
