tesa CaRes® 61445

Repulpable, black single-sided splicing tape

Product description

tesa CaRes® 61445 is a single-sided repulpable splicing tape, with a liner consisting of a flat-back paper and a modified water soluble acrylic adhesive.

tesa CaRes® 61445 special features:
  • The patented calcium resistant adhesive (CaRes) for a maximised life time of permanent splices on papers containing calcium carbonate (CaCO3)
  • Black backing with high colour density for reliable optical detection
  • Thin but strong backing to allow a low total splice thickness
  • Printable and coatable backing for easy further processing

  • Very high shear strength
  • Very high heat resistance
  • Very good adhesion values on most paper grades

tesa CaRes® 51445 is certified by independent laboratories for:
  • Repulpability according to TAPPI UM-213 over full pH-range (pH3 – pH9)

tesa® 61445 CaRes® is a single-sided repulpable splicing tape with liner consisting of a flat-back paper of black colour and a modified water soluble acrylic adhesive.
