Abstract (en)
[origin: WO9003263A1] In a process for improving the rigidity of a flexible, essentially parallepipedal container obtained by shaping and welding a film (2) of synthetic material and which encases the liquid to be packaged, a so-called over-film consisting of a second layer of a film (5) of the same or a different material is applied before shaping to the surface of said film, which does not come into contact with the liquid to be packaged. The over-film consists of multiple strips corresponding to the vertical faces of the final package, said strips being welded to said film before it is shaped according to the lines corresponding to the edges of the final parallepipedal container. Application: packaging of liquids, in particular in the foodstuffs industry.
