MAP - (Modified Atmosphere Packaging)

A process used by supermarkets for increasing the shelf live of 'bagged-up' salad leaves etc. (in this case to around 10 days).

Most of the oxygen is removed from the bag and replaced by carbon dioxide. The contents will almost certainly have been previously washed in a strong solution of chlorine, which effectively sterilises them. There are concerns that the process decreases the vitamin content of the leaves, while the strength of the chlorine solution used might be carcinogenic. For more information see 'Not on the Label' by Felicity Lawrence. Penguin Books.
