Sealers

Sealers are used to join materials like Polyolefin Films.
To seal or weld Polyolefin film around an item by hand, tools like Jaw Sealers, Hand Irons, or Impulse Bar Sealers are used.
L-Bar Sealers are used to weld the plastic film around the item being wrapped more. After being wrapped in the film, a source of heat is applied to shrink the film tightly around the item.

The source of heat for shrinking the films and bands is typically Electric Heat Guns for low-volume operations, or Heat Tunnel Machines for high-volume operations.

For the most streamlined and efficient shrink wrapping of items, Combo Seal and Shrink Systems are available.  These units combine L-Bar Sealers and Heat Tunnels into a single unit.
With the addition of Accumulator Tables or Gravity Conveyors to reduce bottlenecked areas of the process, the number of units wrapped and processed in a day can soar to new heights.
