The first thing you want to consider before ordering a banner is what kind of material will be used. Many discount banner companies use thin fabric, paper, plastic or vinyl, which may work in the short term. But if you want your banner to last for several years, it is important to make sure it is made out of strong material.
At HalfPriceBanners.com, we print only on interior/exterior 13 oz. gloss vinyl reinforced with nylon mesh. This material is very durable, completely opaque, and will last indefinitely if hung indoors, 3-5 years if hung outside, with wind being the biggest factor. We print with a UV-resistant eco-solvent ink that will keep your banners looking new long after you hang them up.
Some companies will charge you to hem and add grommets to your banner. At HalfPriceBanners.com, hemming and grommeting are standard and available at no additional cost. We will heat-weld the hem of your banner on all four sides and add nickel-plated grommets in each corner (spaced out every 3-4 feet along the top and bottom edges.) With Full Color Banners, we can also add more grommets and custom-space them for a small fee. We can also produce your banners with no hemming or grommeting, if requested.
So when shopping around for the best deal, remember that HalfPricebanners.com delivers a higher-quality banner product at about the same price as many discount banner companies.
