Application

Automatic pallet wrapping machine B300 is a machine used for automatically pallet packing, such as plastic container, cases, cartons, bags, etc. The special added film covering function enables the machine to cover the goods with a piece of PE film or plastic foam on the top before wrapping, this makes the package become much more protective than it has ever be. Automatic conveying system increases the efficiency. Upgraded motorized pre-stretch system that allows a large saving of film while wrapping. The whole process will be controlled by central system, no need for manual assistances.

Technological process

The pallet will be placed on the infeed conveyor by forklift. Then motorized conveyor will transfer the pallet to its packing position, film covering mechanism covers the film or foam while the conveyor moving forward. And then auto turntable pallet packing machine starts to wrap the strapped pallet with stretch film (LLDPE) automatically. Finally the pallet will moved out the outfeed conveyor by forklift. One packaging process is fully done.
Note: Infeeding&out feeding conveyor is option.

The film covering mechanism is a specially designed device, it can greatly improve the quality of the package; For certain industries like beverage and frozen food, canned or bagged products can be better preserved by the fully wrapped package. So, merchants usually can make a better sale because of the cleaniness of the appearance.
