Description

MAP TRAY (Modified Atmosphere Packaging), just as its name implies, refers to the technology that artificially controls the Food Packaging Trays proportion of gases (oxygen, carbon dioxide, nitrogen etc.) in the package with the aim of achieving keeping-freshness storage. It is made from a high-barrier multilayer composite plastic. Its the EVOH layer inside that works as a barrier preventing the ambient gases penetrating from the outside. Thats how MAP tray achieves extending the shelf life. And the thickness of EVOH layer contributes to the length of the shelf life. Moreover, the addition of barrier lidding film makes map tray a self-contained BARRIER unit.
