A method for producing a large-capacity, pliable container, includes the steps of a) producing a tubular bellows-type sleeve, b) cutting lateral folding regions of the folded bellows-type sleeve, d) soldering adjacent cutting edges in such a way as to produce a parallelepipedic inner protective envelope having a square cross-section (1b), e) sticking fixing lugs (13) to two opposite lateral fixing faces (14a, 14b) of the folded bellows-type sleeve, (f) applying a tractive force to the fixing lugs (13) in order to deform, by stretching, the parallelepipedic inner protective envelope having a square cross-section and to obtain a parallelepipedic inner protective envelope having a rectangular cross-section (1), step g) soldering the outer lateral pockets (17a, 17b), and a step B) of assembling the inner protective envelope having a rectangular cross-section (1) with the outer envelope in order to form the large-capacity pliable container. |
