The Orbital Seal Head is different from The Orbital Seal Head is different from Box Motion Seal Heads because:Box Motion Seal Heads because:

The Orbital Seal Head does not have to come to a The Orbital Seal Head does not have to come to a complete stop when cycling. This drastically reduces complete stop when cycling. This drastically reduces stress on the components. stress on the components.

The Orbital Seal Head uses inertia to its advantage, it The Orbital Seal Head uses inertia to its advantage, it does not fight against it every cycle like a reciprocating does not fight against it every cycle like a reciprocating Box Motion Seal Head.Box Motion Seal Head.

The Orbital Seal Head will cycle at much higher rates! At The Orbital Seal Head will cycle at much higher rates! At 200 packages per minute the Orbital Seal Head is 200 packages per minute the Orbital Seal Head is exposed to very minimal stresses. A Box Motion Seal exposed to very minimal stresses. A Box Motion Seal Head running at this speed would fail in a very short time Head running at this speed would fail in a very short time due to the repeated high stresses resulting from due to the repeated high stresses resulting from reciprocating motion.reciprocating motion.

The Orbital Seal Head is different from The Orbital Seal Head is different from Rotary Seal Head machines because:Rotary Seal Head machines because:

The Orbital Seal Head knife and cushion maintain vertical The Orbital Seal Head knife and cushion maintain vertical orientation during the entire seal cycle. Vertical orientation orientation during the entire seal cycle. Vertical orientation allows for reduced cutoff lengths and increased film savings. allows for reduced cutoff lengths and increased film savings.
