The vertical collation fully heat shrink machine are more suitable for  Square, rectangular , specially its more suitable for boxes which have more face side contact to product travel conveyors and to collation plate.

There will be two pushers of heat shrink machine ,one pushers pushes the products into upstairs with a proper guide and other pusher will push to web sealer 90 degree to product travel line.

Pneumatic pusher collates the boxes / containers into the pre-selected pack formation, which upon completion is transferred forward into the welding position. At this stage the pack is clamped, the welding bar descents to complete the wrap or seal, and the pusher returns to prepare the next collation of product.

As the welding bar ascends, the pusher advances to transfer the new collation into the welding position, at the same time displacing the previously wrapped collation onto continuously moving shrink tunnel conveyor.

The wrapped collation soon enters the shrink tunnel chamber where re-circulated hot air causes the wrap to shrink and tightly conform to the contours of the contents. Once the pack is out of the hot chamber, forced air cooling is used to tighten sleeve wrap to achieve a strong, secure pack ready for stacking on pallet or a placing on a shipping carton.
