PolyBak PB69 Veneer Backer, Balancer .020" Thickness 31" x 1.800'

PolyBak PB69 Veneer Backer For Laminated Substrates

PolyBak PB69 veneer backer is a standard performance backer from Richwood Industries that provides a balance layer behind laminated substrates. The nominal .020 inch thickness creates a consistent build, which supports flat panels when paired with decorative faces. The brown color helps visually distinguish the back layer from face materials during layout and cutting. Being 2.5 times stronger than a leading saturated Kraft paper backer of the same thickness, PB69 adds toughness behind the laminate, which supports handling during fabrication and installation. The PB69BR28 31X1800 part is supplied in a 31 inch width and 1,800 lineal foot roll, so shops can process long runs without frequent changeovers. Belonging to the Richwood Industries Backers class, this product fits into typical shop workflows where a dependable balancing backer is required on sheet goods.

Key PB69 Backer Details That Support Shop Work

• The nominal .020 inch thickness maintains a predictable backer layer, which simplifies pressing setups when matching overall thickness to face materials on laminated panels.
• The brown color provides clear contrast to many face veneers and laminates, which aids orientation and reduces mix-ups during panel cutting and edge trimming steps.
• At 2.5 times stronger than a leading saturated Kraft paper backer of the same thickness, PB69 withstands panel handling and machining stresses, which supports clean edges and reduced damage in production.
• The PB69BR28 31X1800 format delivers a 31 inch width and 1,800 lineal foot roll, which supports continuous feed operations and long parts with fewer roll changes on lamination lines.
• The performance level designated as Standard sets expectations for everyday backer tasks, which suits routine laminated substrate production where consistent behavior is important across many panels.

Installation And Lamination Use Characteristics

This PB69 poly back backer is most commonly used as a backer for laminated substrates, so it is suited to bond behind high-pressure laminates or similar surfacing during press cycles. The nominal .020 inch thickness offers a uniform caliper, which helps when balancing panel constructions that pair decorative faces with a stable rear layer. Being 2.5 times stronger than a leading saturated Kraft paper backer of comparable thickness, it supports downstream machining such as sawing and boring without the back layer tearing easily. The 31 inch width in this version matches applications where narrower panels or strip lamination are common, while the 1,800 lineal foot roll length allows extended production runs on lamination equipment. The brown color helps operators visually confirm which side is the back during layup, which supports consistent orientation from press through finishing.

Using PB69 Backer In Panel And Column Workflows

Applications For Laminated Substrates And Columns

PB69 is most commonly used as a backer for laminated substrates, so it fits panel shops bonding laminates to cores where a balancing sheet is required on the reverse side. This role helps create stable panels for casework, fixtures, and similar assemblies by pairing decorative faces with a dependable backing layer. PB69 is also used as a paintable overlay for substrates and columns, which means it can form a smooth base surface before a coating system is applied. As a paintable overlay, the standard performance level supports consistent appearance when topcoats are applied, because the backer establishes a known surface over the core. The availability of PB69 in standard widths of 49 inches and 61 inches, beyond this 31 inch format, supports various panel sizes in shops that handle wider layups alongside narrower runs.

Backer Strength, Size, And Roll Length In Practice

The fact that PB69 is 2.5 times stronger than a leading saturated Kraft paper backer of the same thickness has direct impact on shop handling, because panels retain back support when being transferred, stacked, or run through saws. This strength helps maintain edge integrity at the back side during cutting and trimming, which supports cleaner finished edges. The nominal .020 inch thickness simplifies balancing constructions with face materials of similar build, which helps maintain predictable panel thickness across a project run. In this PB69BR28 31X1800 version, the 31 inch width suits narrower components and column wraps where full sheet widths are not necessary, reducing waste when ripping from wider stock. The 1,800 lineal foot roll length supports continuous production of laminated substrates or overlays, which can improve workflow on automated feed lines or repeated press cycles in busy shops.
