The series offers flexibility with 24- and 36-inch tabletop models, a stainless-steel case suitable for sterile environments, and an air exhaust outlet for cleanroom operation. Recipe storage, a resettable seal counter, and lot code capabilities support efficient production tracking and rapid product changeovers.

Users can choose between single- or dual-band operation, Celsius or Fahrenheit display, and over 300 TOSS Alloy 20-C sealing bands. Optional features include a vacuum/purge system for controlled atmosphere packaging, adjustable stand, stainless-steel product table, and water-cooled jaws for specialized sealing requirements.

The PW4400 Series is available with NIST traceable certification and CE compliance to meet global quality standards. PackworldUSA provides a 30-month warranty on all parts, excluding consumables, and lifetime technical support.
