Abstract: A double sided tape has repositional with adhesive associated with a first face. The tape may be in the form of a roll, and the adhesive on the second face may be either repositional or permanent. In order to facilitate rolling, a release liner is provided on one of the adhesive faces. The tape may have perforations, notches, or slits along its length to facilitate detachment of predefined lengths of the tape, as from a dispenser. A tie coat may be applied to each of the faces of the substrate before the adhesive is applied. One face of adhesive can be readily applied to one object (e.g., a shelf or a piece of paper), while the repositional adhesive is then available to removably attach that object to another object (e.g., another piece of paper).

Abstract: An apparatus and method provide for the alternate manufacture of permanent adhesive or repositional linerless labels utilizing the same equipment. Indicia is applied such as by using an intelligent imaging system by at least one print station. With repositional labels, a tie coat is applied and dried, whereas with permanent labels a barrier coating is applied. Coating stations apply a repositional adhesive and release coat in the construction of repositional adhesive labels. The coating station is followed by a dryer and chill rolls. In the construction of permanent adhesive labels a coating station for applying a release coat and a release coat curing station, as well as permanent adhesive application station, are also provided. Changeover time from the manufacture of one type of label to the other is short.

Abstract: A web of labels, particularly linerless labels, is produced which has specially formed perforation lines that are neither too strong or too weak. Each perforation line comprises alternating cuts and ties, including a cut to tie ratio of 0.18.times.0.008 to 0.012.times.0.008, and between 30-58 cuts per inch. Where permanent adhesive is used for the linerless labels, each perforation line comprises 45-58 cuts per inch, and has a percent of hold of 45-58%, with each cut having a thickness of about 0.028 inches. When repositional adhesive is used each perforation line comprises 30-45 cuts per inch, with a percent of hold of 25-35%. At least one, and typically substantially all, of the perforation lines have substantially V or U-shaped enlarged end terminations to facilitate dispensing of the labels. The perforations are formed by applying a perforation pressure of about 500-600 lbs.

Abstract: Linerless label stock is produced from a single substrate utilizing a coating machine by moving the substrate through the coating machine and applying a tie coating to the substrate first face, a release coating to the substrate second face, and a pressure sensitive adhesive to the tie coating. The tie coating comprises a dispersion of a pigment, such as silica, with a binder, such as polyvinyl alcohol. The substrate is cut to form individual labels, and is rolled up into a roll with the release coated second face on the outside of the roll. Printing may be applied to the substrate prior to coating, or to the release coating.
