Featuring a black inner layer that completely blocks light transmission, this material ensures that graphics printed on both sides remain crisp and independent with <strong>zero show-through<\/strong>. Whether you need hanging banners for shopping malls, ceiling flags for trade shows, or promotional displays for 4S dealerships, our <strong>blackout banner<\/strong> delivers professional results with vibrant colors and a smooth, non\u2011curling finish. <strong>1 piece minimum order \u2013 no large MOQ required.<\/strong><\/p>\n<h3>What Is Blockout Banner?<\/h3>\n<p>Blockout banner is a specialized PVC composite material with a three\u2011layer structure: a printable PVC top layer, a black inner light\u2011blocking layer, and another PVC back layer. This construction allows <strong>double-sided printing<\/strong> without any interference between the two sides \u2014 no ghosting, no shadows, no light bleed. Unlike standard banner material that requires lining or lamination for double\u2011sided use, our <strong>blackout flex banner<\/strong> is ready to print on both sides out of the box.<\/p>\n<h3>Key Features &amp; Benefits<\/h3>\n<ul>\n<li><strong>100% opacity<\/strong> \u2013 Black inner layer completely blocks light, ensuring front and back graphics never interfere<\/li>\n<li><strong>Double-sided ready<\/strong> \u2013 Print on both sides without lamination or backing material<\/li>\n<li><strong>Smooth, high\u2011quality surface<\/strong> \u2013 Fine texture with no visible mesh pattern for crisp, vibrant prints<\/li>\n<li><strong>No curling or warping<\/strong> \u2013 Special formulation keeps the material flat, even after printing and hemming<\/li>\n<li><strong>Wide ink compatibility<\/strong> \u2013 Works with solvent, eco\u2011solvent, UV, and latex inks<\/li>\n<li><strong>Excellent weather resistance<\/strong> \u2013 UV\u2011resistant, waterproof, and durable for indoor and outdoor use<\/li>\n<li><strong>Wide width availability<\/strong> \u2013 Up to 3.2m (126 inches) for seamless large\u2011format displays<\/li>\n<\/ul>\n<h3>Technical Specifications<\/h3>\n<table style=\"width: 100%; border-collapse: collapse; margin-bottom: 20px;\">\n<thead>\n<tr style=\"background: #f2f2f2;\">\n<th style=\"padding: 8px; border: 1px solid #ddd;\">Specification<\/th>\n<th style=\"padding: 8px; border: 1px solid #ddd;\">Details<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td style=\"padding: 8px; border: 1px solid #ddd;\">Material Structure<\/td>\n<td style=\"padding: 8px; border: 1px solid #ddd;\">3-layer PVC + black interlayer (blockout)<\/td>\n<\/tr>\n<tr style=\"background: #f9f9f9;\">\n<td style=\"padding: 8px; border: 1px solid #ddd;\">Available Widths<\/td>\n<td style=\"padding: 8px; border: 1px solid #ddd;\">0.914m \u2013 3.2m (36\u2033 \u2013 126\u2033)<\/td>\n<\/tr>\n<tr>\n<td style=\"padding: 8px; border: 1px solid #ddd;\">Opacity<\/td>\n<td style=\"padding: 8px; border: 1px solid #ddd;\">100% \u2013 no light transmission<\/td>\n<\/tr>\n<tr style=\"background: #f9f9f9;\">\n<td style=\"padding: 8px; border: 1px solid #ddd;\">Compatible Inks<\/td>\n<td style=\"padding: 8px; border: 1px solid #ddd;\">Solvent, Eco\u2011Solvent, UV, Latex<\/td>\n<\/tr>\n<tr>\n<td style=\"padding: 8px; border: 1px solid #ddd;\">Surface Finish<\/td>\n<td style=\"padding: 8px; border: 1px solid #ddd;\">Matte, smooth, minimal texture<\/td>\n<\/tr>\n<tr style=\"background: #f9f9f9;\">\n<td style=\"padding: 8px; border: 1px solid #ddd;\">Outdoor Durability<\/td>\n<td style=\"padding: 8px; border: 1px solid #ddd;\">1\u20133 years (with UV ink)<\/td>\n<\/tr>\n<tr>\n<td style=\"padding: 8px; border: 1px solid #ddd;\">Processing<\/td>\n<td style=\"padding: 8px; border: 1px solid #ddd;\">Eyelets, sewing, welding, hems, pole pockets<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h3>Applications \u2013 Where to Use Double-Sided Blockout Banner<\/h3>\n<p>Our <strong>blackout banner material<\/strong> is the industry standard for applications requiring dual\u2011visibility:<\/p>\n<ul>\n<li><strong>Shopping mall ceiling banners<\/strong> \u2013 Suspended displays that can be seen from all angles<\/li>\n<li><strong>Hanging flags &amp; ceiling flags<\/strong> \u2013 360\u00b0 visibility for events and retail spaces<\/li>\n<li><strong>4S dealership displays<\/strong> \u2013 Car showroom banners with promotional messaging on both sides<\/li>\n<li><strong>Trade show exhibits<\/strong> \u2013 Booth backdrops and hanging signs that maximize brand exposure<\/li>\n<li><strong>Retail store signage<\/strong> \u2013 Aisle toppers, hanging promotions, seasonal displays<\/li>\n<li><strong>Concert &amp; event banners<\/strong> \u2013 Stadium, arena, and outdoor event signage<\/li>\n<li><strong>Point of purchase (POP) displays<\/strong> \u2013 Retail fixtures with double-sided branding<\/li>\n<li><strong>Side flags &amp; feather flags<\/strong> \u2013 Pole pocket banners for sidewalk advertising<\/li>\n<li><strong>Museum &amp; gallery displays<\/strong> \u2013 Hanging panels and exhibition graphics<\/li>\n<\/ul>\n<h3>Customization &amp; Ordering Process<\/h3>\n<ol>\n<li><strong>Submit your specifications<\/strong> \u2013 Tell us your required width and quantity.

With UV\u2011cured inks, outdoor durability is 1\u20133 years depending on climate and exposure.<\/p>\n<p><strong>Q3: What inks work best?<\/strong><br \/>\nThe material is compatible with solvent, eco\u2011solvent, UV, and latex inks. For outdoor applications, UV or solvent inks provide the best weather resistance.<\/p>\n<p><strong>Q4: Does the material curl after printing?<\/strong><br \/>\nNo. Our blockout banner is specially formulated to remain flat and resist curling, even after printing and hemming \u2014 ideal for hanging displays.<\/p>\n<p><strong>Q5: What is the maximum width available?<\/strong><br \/>\nWe offer widths up to 3.2 meters (126 inches) for seamless large\u2011format displays. Custom widths available upon request.<\/p>\n<p><strong>Q6: Can I get custom specifications?<\/strong><br \/>\nYes, custom fire ratings (B1, B2, NFPA\u2011701) and UV treatments are available for bulk orders.<\/p>\n<div style=\"background: #f9f9f9; padding: 30px; text-align: center; border-radius: 8px; margin-top: 40px;\">\n<h3>Ready to Order Double-Sided Blockout Banner?<\/h3>\n<p>Send us your width requirements and quantity \u2014 we&#8217;ll provide a detailed quote and material sample within 24 hours. <strong>1 piece minimum, no large MOQ.<\/strong><\/p>\n<p style=\"margin: 20px 0;\"><a style=\"background: #0073aa; color: #fff; padding: 15px 30px; text-decoration: none; border-radius: 4px; font-weight: bold;\" href=\"\/contact\/\">Request a Free Quote<\/a><\/p>\n<p style=\"font-size: 0.9em;\">* All inquiries receive a personal response and technical review.<\/p>\n<\/div>\n<p><!-- \u9690\u85cf\u5173\u952e\u8bcd\u533a\u5757\uff08SEO\u589e\u5f3a\uff09 --><\/p>\n<div style=\"display: none;\">double-sided blockout banner, blackout banner, double-sided printing banner, frontlit blockout, hanging banner fabric, ceiling flag material, trade show banner, black inner layer banner, no light bleed banner, blockout flex banner, double-sided advertising banner, solvent printable banner, UV printable banner<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Double-sided blockout banner with black inner layer for 100% opacity.
