Abstract

1394711 Vacuum packaging NEWPORT GENERAL CORP 13 July 1972 [16 July 1971 24 May 1972] 32799/72 Heading B8C In a vacuum packaging method, an article 22 is placed between sheets 15 and 23 of non- porous, non-cellular, heat-sealable material, the lower sheet 15 being formed with a multitude of convex protrusions 20 whereby collapsible, heat-sealable evacuation channels 21 are defined between the over-lying parts of the sheets and between sheet 15 and vacuum platen 10, heat is applied by lamp 17 to soften the sheets, and the space 34 round article 22 is evacuated by pump 18, the seal between sheets 15, 23 being formed slowly as the protrusions 20 collapse. An adhesive may be used to assist the sealing. In another embodiment, after evacuation, an inert or sterilizing gas may be introduced into the sealed package.
