Proseal’s GT2 tray sealer has enabled Co-operative Farms to reduce waste in soft fruit packaging, also helping to deliver energy savings and cost-efficiency.

Co-operative Farms has recently made a GBP2 million investment in a packing plant at Longforgan, near Dundee, to service its nearby farm in Blairgowrie, one of three packing plants across the UK which packs produce for The Co-operative stores.

As part of the new operation, Co-operative Farms decided to change the closure on its punnets from a clip-on tray lid to sealing film.

Rob Hull, head of vegetable operations for Co-operative Farms, said: ‘Using film requires considerably less packaging material, which consequently reduces the amount of packaging waste.

‘Proseal’s tooling also includes Close Cut Technology, which saves up to an extra 11 per cent in reduced film waste.

‘In addition, film can be applied faster and more cost-effectively and we are using pre-printed film that is more aesthetically pleasing than labelled lids,’ he added.

Co-operative Farms turned to Proseal with a requirement to seal in excess of 90 punnets per minute, 18 hours per day.

Proseal intended GT2 to be a versatile tray sealing solution for the food industry.

It balances the need for optimum throughput with the flexibility to deliver shorter production runs, something essential to accommodate the Co-operative’s range of SKUs.

Using Proseal’s lightweight and high-strength ‘Auto Tool’ connection system, which enables tool changes to be carried out in around three minutes, downtime is minimal, with self-centring pack guides and servo-controlled tray movements ensuring that production is up and running quickly after a tool change.

The Co-operative farms is now considering upgrading to the faster GT2 Twin in a model offering an extra 33 per cent-plus in throughput.

This new model incorporates Proseal’s Eco Seal System, which has been developed in association with the Carbon Trust, and can offer a total energy saving of up to 65 per cent.
