Buffalo Montana PET Poly Blockout Matte Banner Roll | Anti-Curl | Aqueous Inkjet

Montana Poly Blockout Matte Banner Roll is a multi-layer banner media with a white polypropylene (PP) matte print surface, a polyester (PET) structural core for rigidity and anti-curl, and a non-transmissive blockout back coating that prevents light from passing through the graphic. At 10 mil thickness, it is heavier and more rigid than standard single-layer polypropylene banner media — designed specifically for professional roll-up stands, tradeshow panels, and retail display applications where flat, stable, fully opaque graphics are required.

Blockout means the media is fully opaque — light cannot pass through from behind the graphic. Standard banner media is semi-transparent, which causes a washed-out, translucent appearance when light hits the back of the banner from overhead fixtures, neighboring booth lighting, or backlit environments. A blockout banner’s non-transmissive back coating creates an opaque barrier that stops this light bleed-through completely, keeping the graphic vivid and fully saturated regardless of the lighting conditions around the display.

The two materials serve different purposes in the multi-layer construction. The polypropylene (PP) layer forms the white matte print surface — it accepts aqueous inkjet inks with excellent color density and the semi-matte finish reduces glare under display lighting. The polyester (PET) core provides structural rigidity and anti-curl properties that polypropylene alone cannot achieve — PET is stiffer and more dimensionally stable, keeping the banner flat through repeated rolling, transport, and display cycles. Together, PET and PP create a banner that prints beautifully AND lies flat without hemming tape or curl issues.

Yes. The multi-layer PET and PP construction provides the structural rigidity and lay-flat properties that prevent curling. The PET core is the key — polyester has significantly higher dimensional stability than polypropylene, meaning it resists the temperature and humidity changes that cause single-layer banner media to curl at the edges. This anti-curl performance is particularly important for roll-up and retractable banner stand applications where the graphic must retract into and deploy from the base hardware smoothly and flatly every time.

Montana Poly Blockout Matte Banner Roll is compatible with aqueous (waterbase) wide-format inkjet printers using pigment or dye-based inks including HP DesignJet T-series and Z-series, HP PageWide XL, Canon imagePROGRAF PRO, TM, and TX series, Epson SureColor T-series (T3470, T5470, T5770D, T7770D), and Epson SureColor P-series in roll mode. This media is engineered for aqueous inkjet printers only. ICC profiles are available — contact Buffalo Imaging with your printer model and RIP software for a matched profile.

Yes — this is one of its primary applications. The 10 mil PET & PP construction provides the rigidity and lay-flat properties that retractable banner stand hardware requires. Single-layer polypropylene media often waves, curls, or develops a memory from being stored in the retractable base — the PET core in the Montana Poly Blockout resists this deformation and deploys flat every time. The blockout coating also ensures that even if the stand is positioned in front of a bright light source, the graphic stays fully opaque and vivid.

Both are aqueous inkjet blockout banner media, but the Montana Poly Blockout uses a multi-layer PET & PP construction at 10 mil for superior rigidity and anti-curl performance. The Montana Aqua Blockout is a different construction — check the product pages for the specific caliper and base material of each. If you need maximum flatness and rigidity for roll-up stands and tradeshow panels, the Montana Poly Blockout’s PET core gives it a performance advantage. Contact Buffalo Imaging to discuss which product best matches your specific application.

Lamination is not required for indoor applications. The non-transmissive back coating and resin top coat provide adequate durability for tradeshow, retail, and event display use without additional lamination. For outdoor applications or any environment where the printed surface will face moisture, cleaning chemicals, or heavy physical wear, a clear overlaminate is recommended to extend the lifespan of the graphic.

Montana Poly Blockout Matte Banner Roll is available in three widths: 36 inches, 50 inches, and 60 inches. All rolls are 100 feet long with a 3-inch core. Select your width from the product dropdown before adding to cart.
