Doystar

The Doystar is an advanced packaging solution that creates pouches directly from film. It incorporates servo-driven control and rotary die-cutting for precision and efficiency. The machine’s design includes horizontal film unwinding, active film tension control, and a rotary turret with six operational positions, ensuring smooth and consistent performance.

This machine is uniquely adaptable, with five different operating scales built into one machine.

• Simplex: One lane, producing one pouch at a time.
• Duplex: Two lanes, producing two pouches at a time.
• Triplex: Three lanes, producing three pouches at a time.
• Quadruplex: Four lanes, producing four pouches at a time.
• Quintuplex: Five lanes, producing five pouches at a time.

This multi-lane capability increases the machine’s output, enabling higher production speeds and greater efficiency.

The open-frame design allows 360° accessibility, making maintenance and cleaning straightforward. It also features a buffer system between forming and filling sections, enhancing overall efficiency. Capable of converting from Simplex to Quintuplex within 30 minutes, this machine is both versatile and adaptable.
