Siegwerk, global provider of printing inks and coatings for packaging applications and labels, has launched its first full UV flexo deinking system for the European market: CIRKIT CLEARPRIME UV E02. The new primer technology for non-food packaging applications offers a validated solution for safe and economic deinking of UV-printed self-adhesive labels (PSL), according to the company.
Siegwerk ran a first field test of the deinking system with Masterpress, Białystok, Poland, a supplier of labels and printed decorative packaging solutions.
Masterpress’ research and development (R&D) team used uncoated transparent or white pressure sensitive labels (PSL) made of PE85 and applied Siegwerk’s CIRKIT CLEARPRIME UV E02 followed by bleeding resistant UV flexo inks and an UV flexo OPV. First, the primer reportedly created a perfect adhesion between substrate and inks and later enabled full ink and varnish removal of the printed polyethylene (PE) film at standard deinking conditions based on the QT 507 washing protocol of the European PET Bottle Platform (EPBP).
