tesa® 6917
Filmic double-sided bag sealing tape with differential adhesive
Product description
tesa® 6917 has been designed for re-sealable filmic bags. It consists of a transparent double-sided PP-film with a differential adhesive system. The product can easily be cut with the hot wire systems of common bag machine producers.
Due to different adhesion values on each side, tesa® 6917 offers good removability on the covered adhesive side.
tesa® 6917 comes with fingerlift (extended liner) for easy liner removal.
