405 is a 3mil, repulpable, double-coated tape, primarily used for overlaping splices in cellulosic materials. It is tissue coated on both sides with a light green repulpable adhesive. Sealed plastic bags help assure constant moisture content of unused tape. Adhesion to paper increases after short dwell time. Water solubility and alkali dispersability are excellent and eliminate danger of contaminating the paper mill broke by non-repulpable material.
