Buffalo Montana Solvent Block Out Banner Roll 250 gsm | Solvent, Latex & UV | White Back Matte

Buffalo Montana solvent block out banner roll is a 250 gsm matte banner film built on a double-layer PET and polypropylene base with a non-transmissive white blockout coating. Compatible with eco-solvent, solvent, latex, and UV-curable inks on the front and latex and UV inks on the back. HP Latex Certified and Roland Profiled. Available in 36 in (SKU 5-RBW-3610), 42 in (SKU 5-RBW-4210), and 54 in (SKU 5-RBW-5410) widths on 100 ft rolls, it is designed for retractable banner stands, trade show displays, and indoor and outdoor POP signage.

Block out refers to a coating on the back of the banner film that prevents light from passing through. In retractable banner stands, ambient light from behind — windows, overhead lighting, or nearby displays — can pass through a standard banner film and wash out the graphic from behind, reducing color saturation and contrast. A block out coating eliminates this. Buffalo Montana solvent block out banner roll uses a non-transmissive white coating on the back that provides full opacity, ensuring the graphic reads with consistent color and contrast regardless of the lighting environment behind the stand.

Mil is the thickness of the film. A 10 mil film like Buffalo Montana solvent block out banner roll is significantly stiffer and heavier than a 6–7 mil film, which has two practical effects. First, thicker film hangs flatter and is less prone to sagging in banner stand frames. Second, thicker film is more resistant to developing curl or memory from being wound on a roll — an important factor for retractable stands where the film must unroll flat after being wound in a cassette. The 250 gsm weight of the 10 mil SO420 film also contributes to a more durable, professional-looking banner that withstands handling and repeated setup better than lighter-weight materials.

On the front surface, the film is compatible with eco-solvent, solvent, latex, and UV-curable wide format printers — including Roland, Mimaki, Mutoh, HP Latex 300/500/700/800 series, Epson SureColor SC series, Canon latex, and UV roll-to-roll systems. The film is HP Latex Certified and Roland Profiled, so HP Latex and Roland printers can use factory ICC profiles without custom calibration. On the back surface, only latex and UV-curable inks are compatible — eco-solvent and solvent inks should not be used on the back coating.

Yes. The back surface of Buffalo Montana solvent block out banner roll is printable with latex and UV-curable inks only. This makes it suitable for double-sided banner applications where the graphic needs to be visible from both sides — for example, hanging banners in aisle displays or two-sided retractable stands. Note that eco-solvent and solvent inks are not compatible with the back coating and should only be used on the front surface.

The double-layer PET and polypropylene base of Buffalo Montana solvent block out banner roll is specifically engineered for anti-curl performance. The two materials have opposing tension characteristics that counteract each other, keeping the film naturally flat after being wound on a roll or stored in a retractable banner cassette. This matters because single-layer banner films can develop a curl from roll memory that causes the bottom of the graphic to roll back when the banner is extended in a stand. The anti-curl double-layer construction prevents this, producing a graphic that hangs flat and stays flat without additional weighting or taping.

Yes. Buffalo Montana solvent block out banner roll is rated for long-term outdoor use. The 10 mil double-layer PET and PP base provides weather resistance and durability for outdoor POP displays, outdoor event signage, and temporary outdoor banner installations. For extended outdoor exposure, optional overlamination with a UV-resistant protective film extends print life and improves surface protection. The HP Latex Certified front coating is optimized for outdoor-rated HP Latex output specifically.

Store rolls in original packaging at 50–77°F and 35–65% relative humidity. Keep away from direct sunlight, heat sources, and chemical fumes. Shelf life is 1 year in original packaging at recommended conditions. The coating warranty covers 6 months from date of purchase. Allow rolls stored in cold environments to acclimate to room temperature before printing to prevent condensation and ensure consistent ink adhesion on both front and back surfaces.
