Custom poly bag and film manufacturer, A-PAC, has installed two Vetaphone corona treaters at its production facility in Grand Rapids, Michigan.
The company manufactures an extensive range of poly bags including flat, wicketed, gusseted, side-weld, bottom-seal, staple-pack, and custom print as well as poly bags on the roll.
Other products include drum, barrel, gaylord, tote and box liners as well as pallet covers. It also offers three types of plastic film and tubing.
It was the switch from solvent-based to water-based production that first saw the need for surface treatment at A-PAC.
The Vetaphone treaters installed at A-PAC are both C Models, designed to provide a high dyne level on any extruded material.
The electrode design reportedly eliminates fluctuations in dyne levels across the web width and guarantees no undesirable treatment to the reverse side. They feature a Quick-Change system that allows the operator to carry out segment set-up and maintenance in minutes.
