Abstract
Abstract The present invention discloses an adhesive-coated thermoplastic film tape that is readily hand-tearable which comprises an elongate flexible thermoplastic film base having a suitable pressure-sensitive adhesive coated onto one surface thereof. The adhesive-coated thermoplastic film base incorporates a plurality of oriented discrete perforations substantially throughout its entire structure. The non-adhesive-coated surface may further be configured with a plurality of discrete depressions or embossments impressed thereon. A method of producing the novel adhesive-coated thermoplastic film tape discussed above is also described.
