PackworldUSA is a manufacturer of validatable medical heat sealers servicing the medical device, pharmaceutical, and biotech industries.

Packworld uses high-response TOSS Technology to create consistent, repeatable, and validatable heat seals. Many heat sealing machines use thermocouples to control heat sealing elements, providing slow response and inconsistency issues. TOSS Technology uses Variable Resistance Control to monitor and adjust temperature precisely over the full length and width of the heat sealing element.

Packworld and TOSS Technology provide customers with consistent and repeatable seals from one machine to another as well as from the first seal to the last.

Packworld heat seal machines are capable of sealing a variety of materials and specialty bags, including Tyvek, poly, paper, foil, and multilayer films. Sealers can be configured to seal and cut in straight lines or contoured shapes.
