380GSM PVC Black Back Banner Roll for Building Wrap

Jinlong develops the 380GSM 500D×500D (9×9) PVC Black Back Banner, a purpose-built medium-heavy material engineered for full-surround large building wrap projects. Jinlong adopts thick 500D polyester threads woven in a loose yet sturdy 9×9 grid, granting the fabric great flexibility to fit curved wall corners and irregular building facades without cracking during field installation. Jinlong integrates a dense black barrier layer to block all light transmission, ensuring graphics remain vivid even when backlit by interior building lights, a key advantage for long-lasting exterior building cladding. Jinlong formulates a thick weather-resistant PVC coating on every roll, resisting acid rain, strong ultraviolet rays and drastic temperature changes throughout all seasons. Its balanced tensile strength prevents deformation under sustained wind pressure around high-rise constructions, far outperforming lighter thin banners. The soft matte surface absorbs ink uniformly, rendering saturated brand tones and large-scale landscape patterns ideal for full building coverage. Easy to splice and stretch tight on exterior frames, this material streamlines large building wrapping construction work greatly. Beyond building wrap, it also works for long-term roadside enclosure advertising. Combining bendable texture, complete light shielding and all-weather durability, Jinlong’s 380GSM banner is a targeted practical solution for contractors specializing in architectural exterior renovation and brand building wrapping.
