Joe Soletti in the production line

In-line hyperspectral seal inspection enables end-of-line automation for packaging snack trays

Since 1949, one of the most popular television and party snacks has been produced in Austria: the thin, salty pretzel sticks from the brand Soletti. Meanwhile Soletti became part of Kelly Snacks, and the successful product of flour, water, salt and yeast is exported to more than 40 countries. To keep up with the continuous growth, Kelly most recently invested in two new production lines for packaging various types of trays. A key element for these salty snacks is to preserve the crispiness, so seal integrity is critical. That’s why Kelly also integrated two new HyperScope® systems into these production lines, for fully automatic and 100% in-line seal inspection of the single- and multi-compartment trays with transparent as well as printed films.
