New packaging machines unveiled here in Paris provide a complete vaccum seal for trays, while remaining easy to open , claims its manufacturer.

France-based Meca Plastic is demonstrating the range of machines at Emballage, which ends tomorrow. The company says its three machines allow processors to select features such as different capacities in terms of speed, packaging sizes and dimensions.

The company's MecaSkin T seals the lid film on the entire tray and not only on the usual sealing areas. This provides a longer shelf life due to the creation of a total vaccum, the company claims. The machine can also seal foil trays, preventing gas leaks but allowing an easy opening thanks to a special feature on the machine.

"We have found a solution to the important loss of heat usually observed when aluminium is being sealed," the company said. "Therefore the machine saves energy and protects the user."

The company's Slice Pak machine produces a thick pre-formed tray with abarrier liner. Sealing is done for sliced products with a retractable lidding film that resists steaming and provides a high barrier to oxygen.

Processors can easily identify different products running on the same line by being able to use different colours of trays on the machine.
