Abstract: A retroreflective sheeting includes a base layer that includes a thermoplastic polymer. A prism layer is positioned on the base layer. A fabric layer has a thermoplastic coating on a side of the fabric layer, wherein the thermoplastic coating faces the prism layer and wherein portions of the base layer, prism layer, thermoplastic coating, and fabric layer are attached to form a seal. A method for forming a retroreflective sheeting includes providing a base layer that includes a thermoplastic polymer with a prism layer positioned on the layer. A fabric layer having a thermoplastic coating on a side of the fabric layer is positioned with the thermoplastic coating facing the prism layer. A die is applied against the base layer and fabric layer in the presence of sufficient heat to cause the thermoplastic coating on the fabric and the base layer to attach portions of the base layer to the thermoplastic coating on the fabric layer, thereby forming a retroreflective structure.
