Linde Modified Atmosphere Packaging System Extends Shelf Life Naturally

  Linde Modified Atmosphere Packaging System Extends Shelf Life Naturally

Business Wire

MURRAY HILL & NEW PROVIDENCE, N.J. -- October 16, 2012

The MAPAX® modified atmosphere packaging solution from Linde North America can
extend the shelf life of consumer packaged foods when compared to packaging in
air. At the same time, it works in a natural way -- using a combination of
food-grade nitrogen, carbon dioxide (CO[2]), and/or oxygen.

The gases keep sealed products fresh longer when stored under appropriate
conditions, helping to reduce returns due to spoilage. With MAPAX, the shelf
life of cakes can be extended from several weeks to up to one year, pizza from
7-10 days to 2-4 weeks, and raw red meat from 2-4 days to 5-8 days (at
<38^oF). (See Fig. 1.)

Linde is a leading supplier of food-grade gases for the food and beverage
industry. The MAPAX solution includes on-site gas supply and delivery as well
as metering and control systems matched to a plant’s existing food packaging
system. Gases can be precisely metered for high-efficiency inerting and
preservation of a range of bagged, trayed, canned and bottled products, from
potato chips to nuts.

Linde designs a MAPAX-gas solution for many types of packaging equipment
including: deep draw machines, tray sealers, vertical-flow packs, bag-in-box
bag sealing machines, horizontal flow packs, and vacuum-chamber machines.
Linde engineering designs gas control systems to maximize cryogen efficiency.
Sealing in freshness and extending shelf life helps build product and brand
value for bakery, prepared foods and protein products.

The Linde Food Team performs in-plant assessments to identify current
cost-to-chill and works with processors to develop optimal process solutions.
