Abstract
Improved means for constraining a rumen drug delivery device in a rolled configuration, said means comprising a laminate, which may be perforated, comprising a water-permeable material having a low friction surface in the presence of water, said material being bonded by means of a water-dispersible pressure sensitive adhesive to a repulpable tape, said tape having said water-dispersible pressure sensitive adhesive on both its surfaces; a laminate comprising a flexible, water-permeable polymeric material bonded between the low friction surface material and the repulpable tape; and devices constrained by said means.
