tesa® 51903

86µm double sided transparent PVC film tape without liner

  • Double sided tape without liner
  • Different adhesion values on each side
  • Adhesive on each side is precisely balanced, so that tesa® 51903 can be unwound without liner

Product description

tesa® 51903 is a transparent, double-sided adhesive tape without release liner featuring a PVC backing and an acrylic adhesive. The acrylic adhesive system of the double sided linerless tape has different adhesion values on each side which makes tesa® 51903 the perfect solution for box closure applications. The different adhesion values on each side is precisely balanced, so that tesa® 51903 can be unwound easily, even after long periods of storage.

Application Fields

  • tesa® 51903 is ideally used for box closure applications and is even suited for thin film bags
  • Mounting of light weight parts
  • Splicing of various materials such as plastic, metal foils, paper and cardboards
  • Bonding applications in the lithography industry
