Abstract
A resealable hermetically sealed package for food products has the product contained between two sheets of thermoplastic material which are sealed together by a permanent heat fused seal about the product except for one edge along which the sheets are adhesively glued together by an easily peeled resealable seal. The process for manufacturing the product forms the adhesive seal prior to the permanent seals in an area remote from that in which evacuation and the final seal occurs. Thus, the final sealing and evacuation of the package is performed in the absence of adhesive so that no adhesive can be drawn into evacuation slots so as to economically produce the product.
