초록

A controlled environment sealing apparatus includes a reciprocating seal head positioned above an intermittent conveyer carrying product-filled trays, a film feeder to dispense film between the tray and reciprocating seal head, and at least one seal head gassing assembly positioned in the seal head and oriented to direct a flow of controlled environment gas through a cut-out portion of the film into a product-filled tray positioned beneath the seal head. The seal head gassing assembly may preferably direct a high velocity controlled environment gas strea...
