Abstract: This invention discloses a process for forming a pouch having an evacuated headspace containing a flowable material. The process relates to optimizing both, the evacuation of the headspace in the pouch and the accuracy of the flowable material filled in the pouch. Specifically, the present invention employs a process that includes a multiple-step or a continuous compression of the pouch headspace to accomplish the goals. Also disclosed is a vertical form-fill-seal apparatus for forming a pouch containing a flowable material and having an evacuated headspace.

Abstract: In one of its aspects, the present invention relates to a process for forming a flexible liquid-packaging pouch. This process improves fill-accuracy of the flowable material contained in the pouch. Specifically, the invention relates to a process for improving the fill-accuracy of a pouch by incorporating at least one stand-pipe (230) in a balance tank (200) that feeds the pouch (72) with flowable material to be packaged. This invention also relates to such apparatus for improving the fill-accuracy of the flexible liquid-packaging pouch.
