13oz Full Color Banners
The most commonly used material is a heavy weight vinyl technically known as PVC. The weights of the different banner substrates range from as light as 9 ounces to as heavy as 22 ounces per square yard, and may be double- or single-sided. Grommets can also be added in order to facilitate hanging of the banner. Banner hem tapes are also used to protect the lamination of the banner, fasten the hems neatly, and adhere to various surfaces. Large banners (which can be so large that they cover the side of a building) are printed on a special mesh material so that the wind can pass through them.
