History
Controlled Atmosphere Storage (CAS) was used already In the 1930s when ships transporting fruits had high levels of CO2 in their holding rooms, thus increasing the shelf-life of the product. In the 1970s MA packages reached the stores when bacon and fish were sold in retail packs in Mexico. Since then the development has been stable and the interest into MAP has grown due to consumer demand. This has led to advances for example in the design and manufacturing of Bacon films. New techniques are designed, like the use of anti-fogging layer to improve product visibility. From MAP a new packaging technique − EMAP has been developed.

“Considered in its entirety, psychoanalysis won’t do. It’s an end product, moreover, like a dinosaur or a zeppelin; no better theory can ever be erected on its ruins, which will remain for ever one of the saddest and strangest of all landmarks in the history of twentieth-century thought.”
—Peter B. Medawar (1915–1987)
“Like their personal lives, women’s history is fragmented, interrupted; a shadow history of human beings whose existence has been shaped by the efforts and the demands of others.”
—Elizabeth Janeway (b. 1913)
“A man will not need to study history to find out what is best for his own culture.”
