Backers .024" Thick, 25 x 97 Inch

PolyBak PB90 Backer For Laminated Substrates

PolyBak PB90 backer is a .024 inch thick sheet in a 25 x 97 inch size designed as a backer for laminated substrates, so it supports flat, stable panels behind decorative laminates on casework and fixtures. Being 3.5 times stronger than the leading saturated Kraft paper backer of the same thickness, this PB90 sheet provides significantly greater strength, which helps panels resist stress from daily use in woodworking and interior projects. As a product from Richwood Industries, this backer aligns with professional laminate and surfacing workflows, giving shops a consistent, known material for repetitive jobs. The 25 x 97 inch format allows use on longer runs or multiple smaller components from one sheet, which supports efficient layout on the bench. Within the Richwood Industries Backers category, PB90 serves as a workhorse backer where a strong balancing layer is needed behind decorative faces.

Key PolyBak PB90 Backing And Overlay Advantages

• Being 3.5 times stronger than the leading saturated Kraft paper backer of the same thickness, PolyBak PB90 delivers a more robust backing layer, which supports panels that stay straighter under service loads and handling in the shop.
• Used as an excellent strength balancing backer for substrates faced with decorative laminates, PB90 helps equalize forces on both faces of the panel, which supports reduced tendency toward warp when laminates are bonded on the opposite side.
• Serving as an excellent veneer crossband, this backer works between veneer and core materials, which supports a more uniform structure when building veneer layups or architectural panels.
• Used simply as a balancing backer, PB90 provides a consistent secondary face, which supports stable construction when only one side of a panel carries a decorative laminate.
• Functioning as a paintable overlay for substrates and columns, this sheet takes paint over its surface, which lets shops create finished columns or panels using the same PB90 material as a uniform paint base.

Backer Sheet Dimensions And Application Use

This PolyBak PB90 backer is specified at .024 inch thickness, so it adds only a thin structural layer, which supports strength balancing without substantially increasing panel thickness. The 25 x 97 inch sheet size covers longer panels or multiple cabinet parts, supporting efficient nesting of components along the length. As part of the Richwood Industries Backers line, this PB90 format fits directly into laminate and veneer fabrication workflows, supporting consistent results when panels are pressed. When used as a backer for laminated substrates or as a paintable overlay for substrates and columns, these dimensions give shops flexibility to cut parts for doors, sides, or column wraps from the same sheet.

Using PolyBak PB90 Backer In Woodworking Projects

Where PolyBak PB90 Backer Performs Best

PolyBak PB90 backer is most commonly used as a backer for laminated substrates, so it fits naturally into casework, fixture, and interior panel runs that rely on decorative laminates on the show face. As an excellent strength balancing backer for substrates faced with decorative laminates, PB90 supports panels that need a stable rear face behind high-pressure or decorative laminate fronts in commercial or shop-built projects. Its role as an excellent veneer crossband makes it suitable in veneer layups where a controlled layer sits between veneer and core, which matters when fabricating doors, panels, or custom components that require a balanced build. When used simply as a balancing backer, this PB90 sheet supports panels that carry a decorative surface on one side and need a consistent backing layer on the opposite side for dimensional stability. As a paintable overlay for substrates and columns, PB90 supports column wraps or panels that receive a paint finish over a uniform surface, which helps maintain a consistent appearance across multiple pieces.

Why PolyBak PB90 Details Support Repeatable Results

At 3.5 times stronger than the leading saturated Kraft paper backer of the same thickness, PolyBak PB90 offers a strength margin that supports panels during handling, transport within the shop, and service in installed environments. That strength advantage contributes to backers that continue to perform behind decorative laminates or veneer, which can reduce the risk of surface telegraphing from backing failure. The .024 inch thickness provides a predictable caliper in panel build-ups, which supports repeatable press setups and consistent total panel thickness across jobs using this same Richwood Industries backer. The 25 x 97 inch size gives fabricators a standardized sheet dimension that aligns with typical panel layouts, which supports efficient cutting patterns when backing doors, sides, and tall components. Because PolyBak PB90 is used as a paintable overlay for substrates and columns, shops can rely on one backer material to serve both as a balancing layer and as a paint-ready surface, which simplifies material choices across related projects.
