Vinyl Banner Materials
There are 2 types of solid banner materials, one being the standard scrim vinyl which is used for most one sided banners, and the other is a blockout material that is made of 3 layers of vinyl with the middle layer being a black light blocking material.
Vinyl banner material comes in different thicknesses and they are based on the weight per square yard. So a 13oz banner will weigh 13oz for every 9 sf (16oz = 1 lb). So the higher the "oz" the thicker the material is. The actual thickness of the material is also close to the weight with a 13oz banner thickness of .013, and 10 oz at .010.
Standard vinyl banner - A good utility thickness is the 13oz, which is used in 75% of the banners we make. It will last for a couple years outdoors as long as it is not allowed to flap in the wind. A 10oz material will not last outside for very long and with the price difference being so small we generally don't recommend it and cary very little in stock. We have this material in widths up to 98" and we also have the capability of sewing sections together to make even wider banners.
Blockout banner material - Generally used for banners that may be 2 sided and/or where you don't want the light to come through the back of the banner. If you did a 2 sided standard vinyl street banner the image from the back side would show through slightly and make the banner harder to read. A blockout banner will stop most of the light from coming through with the black middle layer of vinyl being opaque. Use blockout whenever there may be a back light source that you don't want to come through. Blockout is also more dimensionally stable because of it's 3 layer construction and will be smoother and lay flatter. We recommend the blockout for tradeshow backdrop banners because of it's smooth and flat look. We carry this material in 15oz and up to 98" in width.
