A Semi-Automatic Strapping Machine is a packaging machine used to strap cartons, boxes, bundles, or pallets using plastic straps such as PP (polypropylene) or PET. It is called semi-automatic because the operator manually places the strap around the package, while the machine automatically tightens, seals, and cuts the strap.
How It Works
-
The operator places the box or bundle on the machine table.
-
The strap is manually wrapped around the package and inserted into the machine slot.
-
The machine automatically tensions the strap, heat-seals it, and cuts the excess strap.
-
The next strap length is fed automatically, ready for the next cycle.
