Proseal is a British manufacturer of tray sealing machines headquartered in Adlington, Cheshire, and part of JBT Corporation since 2019. Its GT series covers semi-automatic to fully automatic high-speed tray sealers, including the GT2s, GT4s and GT6s, engineered around fast tool-less tool change, servo-controlled sealing and hygienic washdown frames for protein and produce environments.
The company's focus is sealing speed with format flexibility: lines are frequently specified with automatic tray de-nesters, denesters and lane dividers so a single sealer can feed multiple downstream weigh-price labellers. Proseal systems support MAP gas flushing, vacuum skin and skin-pack applications, and are typically integrated by OEMs and line builders rather than sold as standalone machines.
For buyers, Proseal represents the mid-to-high-speed tier of tray sealing: faster than a semi-automatic sealer, more flexible than a fully dedicated high-volume line, with a strong installed base in UK and European fresh-food plants.
