TESA® DOUBLE-SIDED TAPES

tesa® 61970 – High-Performance Double-Sided Tape for Packaging Solutions
tesa® 61970 is a transparent, double-sided tape designed with a PP backing and a highly tackified acrylic adhesive. Specifically crafted for the closure of corrugated-board cartons, this tape ensures secure and durable bonding even on rough or uneven surfaces. With its enhanced adhesive properties, it performs reliably in high-temperature environments.
Featuring a convenient fingerlift (extended liner), tesa® 61970 streamlines the application process by allowing fast and easy liner removal. Recycling-friendly according to the INGEDE method, this tape offers a sustainable solution for modern packaging needs.
