Abstract
A modified atmosphere flow-wrap system and method and components thereof are provided for packaging a food product in a reduced oxygen atmosphere in a continuous or partially-continuous process. In one aspect, the flow-wrap system includes a saturation tunnel for saturating the food products with modified gas to reduce an amount of residual oxygen therein. In another aspect, the flow-wrap system includes a flow-wrapping station with a modified gas lance that extends into film webbing used to form the food product packages to insert modified gas into the film webbing and restrict oxygen from entering the food packages.
