The most common materials used to create point of purchase displays are metal, wood, and plastic. Within the category of plastics, the most common types are acrylic, PVC, vacuum formed plastic and injection molded plastic. Vacuum formed and injection molded plastics require an upfront investment in molds and are therefore most commonly used for larger production runs that allow for the mold cost to be amortized across the larger number of units produced. Acrylic and PVC are typically manufactured in 4’x8’ sheets of varying thicknesses. Acrylic is considered a higher-end material and is more expensive than PVC, but it has the advantage of being available in clear which enables better product visibility.
