Below is a list of Poster Tubes manufacturers from New Oxford, Pennsylvania. Poster tubes are a type of mailing or shipping tube that are used to safely transport roll-able, unframed art that cannot be folded. They may also carry items like blueprints, large papers, signs, banners and important documents that must remain uncreased. They provide adequate protection against denting, dropping, crushing and bending that may occur because of rough handling during transit.
