This invention relates to tear tapes for convenient and simple opening of packages, such as consumer item package wrappers. Known methods of fixing tear tapes to package overwrap material require the use of an organic solvent, molten wax, a hot wheel or shoe, or a pressure sensitive adhesive. The hot shoe method wrinkles the package while tear tape packages made from pressure sensitive adhesives are costly, difficult to manufacture, handle, and store. The present method of making a packaging material (24) includes steps of providing a tear tape (20) having a fusible surface, contacting the fusible tear tape surface with a surface of a wrapping material (22), and directing radiant energy (16) toward a portion of the fusible surface. Also, apparatus (10) for carrying out the method, and packaging material (24) made by the method are disclosed. |
