Deep skin tray sealing solution

13 June 2016

Proseal has introduced what it believes is the world’s first semi-automatic tray sealer for skin-deep packs. 

The Proseal GTR-E is able to seal products that sit up to 100mm above the edge of the tray, making it suitable for large pieces of meat and joints. The film wraps tightly around the meat, helping to extend shelf life of the product without the need for gas flushing, and also enhances product presentation.

The new tray sealing solution was developed in association with the first customer for the machine, Rhug Estate, an award-winning organic farm in Denbighshire. To meet Rhug Estate’s need for maximum flexibility, as well as being able to handle skin deep packs, the GTR-E needed to be able to seal a variety of other pack types, including standard, gas flushed, and vacuum gas flushed trays, and ordinary skin pack trays. Tool changes between standard, skin pack and skin-deep formats take just five minutes.

The new model also incorporates Proseal’s own E-seal technology, a high force electric seal system that creates a very tight and reliable seal while reducing compressed air usage by over 90%, which offers energy and cost savings.

The machine’s semi-automatic operation makes it suitable for smaller scale enterprises, which do not require a fully automatic in-line tray sealer, while its compact dimensions mean it can fit into the smallest of factory spaces.

Unlike traditional manual machines, where the operator has to wait for each tray to be sealed, the rotary operation of the GTR-E allows for a new tray to be loaded while the previous one is being sealed, delivering higher speeds and efficiencies to meet production line requirements.

Commenting on the solution, Gary Jones Rhug Estate cutting plant manager, said: “We needed a tray sealing machine that would ensure our high quality meat was both presented and protected effectively, in order to reach our customers in premium condition.

“With limited space available in our packing operation, we approached Proseal to help us come up with an appropriate solution. The GTR-E meets our requirements, and we have been delighted with the high standard of service from Proseal and the reliability and efficiency of the machine.”
