Abstract
The invention relates to a method for the manufacture of at least one flexible plastic container, according to which method each container (10) comprises two separate walls (12, 13) facing one another joined at their circumference by a sealed peripheral edge (14), said separate walls defining a storage space of the container (10). According to the invention, at least the following stages are realized:
- a) Forming a pile of two sheets (26, 27) of plastic material, said sheets (26, 27) being laid one against the other, the surfaces which face one another of these sheets (26, 27) being placed directly in contact with one another without any element acting as an interface,b) Simultaneously shaping said sheets (26, 27) thus laid one against the other in order to define said at least one container (10) without having previously separated these sheets, at least each container (10) being partially formed, said sheets (26, 27) being maintained lying one against the other in at least one section of the areas of said sheets (26, 27) intended to constitute said peripheral edge (14) of each container (10) during this shaping andc) Sealing at least partially the areas of said sheets (26, 27) intended to constitute said peripheral edge (14) of at least each container (10).
