JVCC MAG-01-W Writeable Magnetic Tape (No Adhesive)JVCC MAG-01-W Writeable Magnetic Tape is comprised of a multipole one face flexible magnet (composite of strontium and/or barium ferrite particles oriented with a thermoplastic polymer matrix). These permanent magnets remain magnetized indefinitely if not subjected to a demagnetizing force. This tape is not returnable for this reason. The tapes marked as write-on/wipe-off have a non-porous, smooth, and shiny white vinyl surface. Writeable with a dry erase marker and just wipe off. Applications include warehouse labels, store/retail shelf labels, schedule/planning boards, and control charts. The tapes marked as writeable have a porous, writeable, screen-printable matte white vinyl surface. Writeable with a permanent marker, or with a water soluble marker (wipe off with a damp rag) for non-permanent applications. Note, wiping off will gray surface over time. Applications include: automobile signs, marketing displays/premiums, business cards, warehouse/barcode labels, and control charts.
