tesa® 51903

86µm double sided transparent PVC film tape 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 are precisely balanced, so that tesa® 51903 can be unwound easily, even after long periods of storage.
