The oven-ready packaging for chilled or frozen food products is based on the Mylar Cook concept, produced by the joint US and Japanese venture DuPont Teijin Films. The seal seam of the pack opens by itself in the oven once a defined pressure is reached, enabling cooking vapour to escape. A dry phase arises from the wet cooking cycle, which means the food is browned in the open pack.
This approach eliminates the need for additional valves. “This makes this design clearly more cost-efficient and achieves higher quality,” claims Valeska Haux, marketing director at Multivac.
Mylar Cook was originally developed for the packaging of protein but can also be used for convenience foods and bakery.
