M.A.P. AND REDUCING FOOD WASTE Wasting food has a huge environmental impact. it wases energy and water that it took to create it and generates 11 percent of the world’s emissions. America plays a large part in this with nearly 40 million tons of food going to waste every year, more than any other country.* There are many reasons for this but extending food shelf life is proven to have a positive impact in reducing food waste and that is where modified atmosphere packaging M.A.P. comes in. Packaging is an indispensable element for the food industry. The most important role for any packaging solution is to protect the product and preserve the food for longer. Packaging solutions like heat-sealable and M.A.P. can extend the freshness for days (depending on contents). This extension of shelf life works through reducing the content exposure to oxygen thus preserving without the need for artificial preservatives.



Each day refrigerated lorries transport freshly prepared food-to-go dishes to hundreds of convenience stores, major supermarket chains, and transport companies across Belgium and into France. Guaranteeing a fresh product and maintaining the quality of the high-end ingredients is paramount. Consequently, packaging and the way the packs are sealed, plays a vital role. By working with Colpac and selecting the right packaging solutions, Nonna has consistently met its shelf life objectives, which in turn has enabled its customers to sell more products over a longer period, while dramatically reducing avoidable food waste. To achieve this, a recyclable, Modified Atmosphere Packaging (M.A.P.) sandwich pack was developed, printed with an eye-catching design with a clear window for product visibility. To seal the packs a ColMAP ™ Slalom automatic sealing machine was installed. This machine has a sealing system that replaces the oxygen within the sealed pack with a mixture of protective gases to preserve the freshness of the product, extending shelf life by up to 10 days.

Belgium based Nonna produces almost four million packs of fresh sandwiches, tortillas and salads each year.

When Nonna looked to expand their offering to include salads and tortillas, the solution was a custom printed, recyclable Heat Seal Tortilla Pack, with a ColSeal ® SE1000 Sealing Machine, which can extend the product shelf life by up to 5 days.

OUR PACKAGING Modified Atmosphere Packaging (M.A.P.) is a shelf-life extension technique for fresh food, which is achieved by replacing the oxygen within a sealed pack with a protective gas mix through controlled vacuum. The removal of oxygen inhibits the growth of microbes and slows down the process of food decay. Together with lowering the storage temperature and maximising the levels of hygiene during production and packing, the product will stay fresh for significantly longer. The ColMAP™ range of packaging in paperboard consists of sandwich packs and lidded trays. These are manufactured from recyclable paperboard laminated with a high barrier, multi-layer film, suitable for food grade gases.

Our ColMAP™ range of packaging and machinery has been designed and developed over several years by our team of experts. We have installed MAP sealing machinery lines with food manufacturers and processors around the world. • M.A.P. reduces the need for artificial preservatives, which is great for retailers to eliminate as many additives as possible on their labels and show that food is fresh and natural. • M.A.P. can increase the expected shelf-life by up to 10 days depending on ingredients and supply chain conditions. • A longer shelf-life means that the product can be shipped over longer distances, which can increase the range of distribution and reduces the number of deliveries. Additionally this gives the opportunity to sell product over a longer period of time • The extended shelf-life achievable means there will be less frequent product replacement requirements which will lead to supply chain efficiencies and increased on-shelf availability. • ColMAP™ packaging typically contains only 15% of the plastic (by weight) of the equivalent full plastic packs.
