A heat-sealable thermoprintable tape includes an extruded thermoplastic coating having a smooth printable surface on a first side, and an extruded heat-seal polymer layer disposed on a second side of the extruded thermoplastic coating, opposite the first side. The extruded thermoplastic coating is bonded to the heat-seal polymer layer to form the heat-sealable thermoprintable tape. A method of forming a heat-sealable thermoprintable tape includes providing a support layer having an open structure configured to support an extruded coating, applying a polyurethane coating onto a first side of the support layer and into open spaces of the open structure to form a top surface, and extruding a heat-sealable polymer onto a second side of the support layer opposite the first side and into the open spaces of the open structure. The polyurethane coating bonds to the heat-sealable polymer within the open structure of the support layer.
