The Vacuum Bag Filler
Vacuum bag filling was originated by Modern Machine Shop 60 years ago and has been the industry leader by which all vacuum bagging is measured. The accomplishments in the field of vacuum packaging go back to the pre-World War II era when can, box, drum, and explosive filling were extensively used for military applications. These processes have been modified and refined through the years and we now can supply a full line of vacuum filling services:
- Kraft bags
- Poly bags
- Tyvek bags
- Boxes
- Fiber & metal drums
- Bulk bags
- Special shape containers
- Densifying
Also available are material supply hoppers, transfer units, screeners, and special application engineering.
