Tray-shaped container of flexible material and relative manufacturing method and apparatus

Abstract

A container of flexible material and a relative production method, whereby the container, with at least three dimensions (sides) is formed from a flat sheet which is die-cut (2) in a polygonal shape from single- or multi-layer material by performing pleating of the portions of pleating (d) near the apexes, so as to raise—with respect to a bottom wall (a)—side walls (b) and connecting walls (c) between the adjacent side walls. A peripheral edge (10) of the blank is then folded over and secured to a stiffening frame, if any, having the same polygonal shape as the bottom of the blank. A covering sheet, also a single- or multi-layer sheet, can cover the container (1) and be removed by peeling or otherwise, an operation with is facilitated by the provision of a pull tab.
