Automatic Sleeve Bundling Wrapping Machines Products are fed in a single or Multi lane file and then collated into a pre selected pack format. Once formed, the pack is pushed to its welding position where it is clamped before welding. The wrapped product is then transferred to the shrink tunnel where re circulated hot air in its chamber causes the wrap to shrink around the pack. Once outside the chamber, cool air is blown on the product to quicken the cooling process. On cooling the wrap strengthens and shrinks further. The end result is a rigid package that is ready for stacking on a pallet or placed in a shipping carton. Advantages : Primary - Where the product is totally enclosed for protection from abrasion, dust, moisture and for improved appeal. Secondary- where a group of items is wrapped together to form a Sales unit, (Six packs of Beer, Juice etc) Distribution packaging- Where product is wrapped into a distribution unit which may stacked directly on the pallet ready for transportation.
