Abstract:
1. A method for manufacturing an inherently stable container made of flexible material, comprising the following steps: a) folding a continuous film of flexible material of appropriate width, to obtain a pouch having a longitudinal heat-seal and evenly spaced transverse heat-seals, followed by cropping the folded film in a direction transverse to the longitudinal heat seal; b) heat-sealing in sides of the pouch, at a region of the transverse heat-seals, forming two triangles having wings laterally disposed relative to the longitudinal heat-seal; c) punch opening said pouch, and optionally filling the pouch with a product; d) folding and bonding the wings laterally relative to the longitudinal heat-seal and, after filling the pouch, simultaneously with the bonding off the wings, heat-sealing an upper open mouth of the pouch.
