Skin tight sealing solution for trays

Proseal has further extended its range of vacuum tray sealers with the launch of a model specifically designed for skin packs.

The Proseal GT1VS features a servo-driven infeed conveyor and high accuracy tray positioning system and accepts randomly spaced trays in all types of materials at sealing speeds of up to 24 packs per minute depending on the product.

Skin packs feature a special film that seals to all surfaces of a tray - rim, sidewalls and base - to tightly cover the contents. The packs have been used predominantly for fish products in the past but are now being used for other foods such as ready to cook meals, game, meat and sausage products, and mini joints.

Wrapping the seal around the contents means products can be vacuumed packed for extended shelf life without the need for gas flushing.

As there is no gas headspace needed, tray heights can be reduced, thus saving on packaging materials. The sealing system also means product can extend over the height of the tray. Benefits are said to include lower weight and reduced handling and storage costs for the packs, and the minimising of food waste.

Skin packs are said to offer enhanced on-shelf presentation, enabling products to be clearly seen; packs can be placed upright to maximise shelf space. Tight seals also eliminate leakage for products containing sauces.

The GT1VS incorporates a special auto connect tool docking facility, with lead-less and hose-less connection of both gas and electrical supply, to enable tool changes to be carried out in minutes.
