Corona Treaters for
film manufacturers
Blown film extrusion usually requires a corona treater to treat both external faces of polyethylene film (although polypropylene can also be treated). Corona treaters by Corona Supplies allow for guaranteed dyne levels, even at high slip additive levels, using a variety of easy to use and safe to operate designs.
