The GT5 is an automatic, extra-large capacity, single lane, high speed tray sealing system designed to cut labour costs and produce speeds up to 105 packs per minute.



The GT5 is an automatic, extra-large capacity, single lane, high speed tray sealing system designed to cut labour costs and produce speeds up to 105 packs per minute.

The GT5 is a high throughput modular, single lane linear tray sealing system, designed to run in conjunction with auxiliary equipment such as tray de-nesters, fillers, multihead weighers and labellers, combining into a stand-alone, fully automatic production line.

At the core of the design is its flexibility to perform any style of heat seal to a pre-formed tray, be that atmospheric, MAP, VMAP, SKIN, SKIN PLUS, or SKIN DEEP. Each of these options can be added now or a later date, or indeed removed as necessary. This flexibility provides the user with the assurance that whatever the latest packing trend might be, they have equipment suitably geared for the future.
