Zusammenfassung:A process for forming a pouch having an evacuated headspace containing a flowable material is disclosed. The process includes the steps of: providing a continuous tube of flexible and sealable film; supplying the continuous tube with a predetermined amount of flowable material; pinching the continuous tube above a sealing region so as to form a pinched portion of the continuous tube; evacuating the headspace between the pinched portion and the predetermined amount of flowable material; and sealing the continuous tube at the sealing region to form a top seal of a previously formed pouch containing flowable material and a bottom seal of a next-to-be filled pouch. Also disclosed is a vertical form-fill-seal apparatus for forming a pouch containing a flowable material and having an evacuated headspace.
