PRATIKA 80-T MPS: the automatic shrink wrapping machine for continuous sealing

The PRATIKA 80-T MPS is an automatic shrink wrapping machine equipped with a Side Seal device.
The acronym MPS identifies the continuous side sealing system, which removes product length limits: thanks to this technology, it is possible to package very long or variable-length products, up to 4, 5 or 6 meters, while maintaining a continuous workflow and high productivity.

This machine, suitable for packaging formats up to 700 mm wide x 360 mm high, has been strengthened in all mechanical and electronic components to reach production of up to 3000 pieces per hour (depending on product size and the film used).

PRATIKA 80-T MPS, an innovative shrink wrapping machine, represents the perfect combination of reliability, high performance, versatility and safety, once again evolving the concept of automatic packaging machines with shrink film.

“Made in Italy with an international heart”: all minipack®-torre automatic packaging machines are manufactured entirely in the company’s production facilities, while at their core are electrical and electronic components from a multinational company such as Schneider Electric.
