Forming a tray by providing a tray laminate comprising a fibrous web (21) bonded to a web of a gas barrier film (20) comprising a multi-layer laminate comprising a heat sealable layer and a gas barrier layer. Vacuum and/or thermoforming the laminate to create a tray with an upstanding rim. Filling the tray with a food product (F). Providing a web of lid film (13), the lid film (13) being a gas barrier film comprising a multi-layer laminate comprising a heat sealable layer and a gas barrier layer. Heat sealing the lid film (13) to the gas barrier film of the tray around the periphery of the tray to create a hermetic seal between the two barrier films. Severing the pack from the webs of material.
