Materials
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.

Famous quotes containing the word materials:
“The competent leader of men cares little for the niceties of other peoples’ characters: he cares much—everything—for the exterior uses to which they may be put.... These are men to be moved. How should he move them? He supplies the power; others simply the materials on which that power operates.”
—Woodrow Wilson (1856–1924)
“What is most interesting and valuable in it, however, is not the materials for the history of Pontiac, or Braddock, or the Northwest, which it furnishes; not the annals of the country, but the natural facts, or perennials, which are ever without date. When out of history the truth shall be extracted, it will have shed its dates like withered leaves.”
—Henry David Thoreau (1817–1862)
“Young children learn in a different manner from that of older children and adults, yet we can teach them many things if we adapt our materials and mode of instruction to their level of ability. But we miseducate young children when we assume that their learning abilities are comparable to those of older children and that they can be taught with materials and with the same instructional procedures appropriate to school-age children.”
—David Elkind (20th century)
