PolyBak Baker & Overlay Options

PolyBak PGB PolyBak PGB

PGB is PolyBak's most economical balancing backer or paintable overlay. Available in brown and black, PGB is extremely flexible, but stronger than competing Kraft paper backers. Like all PolyBak™ models, PGB has an unlimited shelf life.

PolyBak PB42 PolyBak PB42

PB42 is a great choice for a low cost balancing backer or paintable overlay. It has properties similar to the lower cost PolyBak™ PGB, but with even greater tensile strength and moisture resistance.

PolyBak PB69VNR

 PolyBak PB69VNR

PolyBak™ PB69VNR is often adhered to wood veneer to increase the stability, flexibility and moisture resistance of the veneer (cross banding). Its combined strength and flexibility standards make it a great balancing backer for many applications.

PolyBak PB69 PolyBak PB69

With just the right mix of performance and economy, PB69 is our most popular PolyBak™ backer. At 2.5 times stronger than the leading saturated Kraft paper backer of the same thickness, PB69 is most commonly used as a backer for laminated substrates, but is also used as a paintable overlay for substrates and columns.

PolyBak PB67VNR PolyBak PB67VNR

This ivory PolyBak™ is very versatile due to its color. Though it is often used for cross banding in the veneer industry, the ivory color makes it an excellent option for use as a paintable and stainable overlay.

PolyBak PB90 PolyBak PB90

At 3.5 times stronger than the leading saturated Kraft paper backer of the same thickness, PolyBak™ PB90 is most commonly used as a backer for laminated substrates. It is also used as a paintable overlay for substrates and columns.

PolyBak PB90HP
PolyBak PB90HP

At 3.5 times stronger than the leading saturated kraft paper backer of the same thickness, PolyBak™ PB90HP is most commonly used as a backer for laminated substrates. It is also used as a paintable overlay for substrates and columns. PB90HP has greater moisture resistance than PB90.
