Abstract
A banner including a bonded nonwoven polyolefin film-fibril sheet having front and back surfaces and having two side edges intersecting top and bottom edges to define four corners. The side edges are generally linear and are folded-over onto the back surface of the sheet and secured with double-faced adhesive tape to form a laminated edgefold with the double-faced adhesive tape sandwiched between two layers of the sheet. The front surface of the sheet has at least a first coating of surface-sealing polymer and means are provided adjacent each corner for attaching cords to the edgefold for hanging the banner.
