BLSD 70 is a high-performance continuous sealing machine with speeds up to 60pq/min. due to the predictive
movement of the jaw that prevents the stop in the welding process.
BLSD 70 is a very versatile mechanical machine since the continuous welding feature allows to pack or shrinkpack
products of any length.
Fully automatic, for bagging or shrink packaging if a shrink tunnel is incorporated.
