Vinyl banners are flexible banner signs made from PVC sheeting. They are commonly used for outdoor advertising and temporary signage, and are typically printed with a wide-format printer and finished with hems and grommets for mounting.
The weights of the different banner substrates range from 9 oz/sq yd (310 g/m2) to 22 oz/sq yd (750 g/m2), and may be double- or single-sided. Large banners are usually manufactured with a special mesh material that is UV and wind resistant.
Common types include:
A vinyl banner usually uses an outside hem to ensure that grommets can be secured properly. [1] If grommets are fastened through a single layer rather than through the hem (double layer), they can rip out more easily; hemming provides a stronger grip and durability, particularly outdoors. [1] Banner hem tapes are also used as decorative trim and to prevent delamination and lifting of vinyl hems.[ citation needed ]
