A thin polyester film coated on one side with an aggressive, permanent rubber adhesive and on the other with a removable rubber based adhesive. The permanent (Hi) side shows good initial adhesion to a wide range of surfaces. The removable (Lo) side peels off most smooth surfaces without damage or residue. The release liner is made from a densified kraft paper. The liner is ¼” wider than the adhesive to facilitate easy removal.
Applications include: recloseable envelopes and bags, advertising novelties, business forms and temporary signs.
