SealedAir-Cryovac has patented the Cryovac Mirabella system. This offers a slimline packaging solution, with an effect similar to conventional MAP protective gas packaging, and a reduction in the packaging height of up to 40%. The Mirabella film, however, requires a highly sophisticated die in the packaging machine, because it consists of two layers which must be shrunk with precision control. If the die, which heats the film to the correct shrink temperature, is not heated sufficiently, the film creases, detracting from the appearance of the pack and putting off the consumer.
Conversely, if the die becomes too hot, the two layers of film stick together, with the result that the cushion of air provided by the Mirabella film will be too small to store sufficient oxygen. Multivac traysealers have now passed the first stage of the certification process for use with the Cryovac Mirabella system. The machines, which are fitted with a new die system, seal trays just as efficiently as the conventional models. And the system is also compatible with previous models. The older T 350 and T 400 traysealer models can be fitted with retrofit kits for processing Mirabella® film; the new T 700 traysealer does not require retrofitting. Tests for the top of the range T 800 model have just begun.
