Clear plastic sealing is applied and vacuum is used to extract the air from the package
Often times certain gas mixtures are introduced back into the tray to extend shelf life
This process is known as Modified Atmospheric Packaging (MAP)
Special “oxygen rated” vacuum pumps must be used for this MAP process

classsificadas segundo o teor de oxigênio residual
No caso a explicação é clara, o que se deseja é evitar a presença de oxigênio na embalagem. Ouando o txto diz "Often times certain gas mixtures are introduced back into the tray to extend shelf life" - significa: se injeta um gás inerte,em geral nitrogênio puro para diluir o ar restante, e em seguida de bombeia de novo com a bomba de vácuo. Portanto o "oxigen rated" vai ser algo como: garantida para (por exemplo) 0,000001 de oxigênio. O link que postei abaixo da Lablink se refereespecificamente a teor de oxigênio residual na embalagem de produtos farmacêuticos.
Example sentence:
A utilização de MAP (embalagem em atmosfera modificada) em produtos alimentares frescos mantém a aparência, a frescura e o sabor.

Oxygen rich environments can promote combustion, and even result in spontaneous combusti on under conditions of high pressure and exposure to contamination.
Use only oxygen-rated components, and ensure that components are oxygen clean prior to use with pure oxygen
