Abstract

Packaging material comprises a panel of expanded synthetic resin of very low density which has a certain rigidity initially, and in >=1 surface of which are formed a series of parallel hinge grooves with good mechanical strength, to allow the panel to bend. The grooves are formed by a heating plate bearing blades which are embedded in the panel not only to form the grooves, but also so compress the particles of synthetic resin, so as to form connecting zones of greater density of material at the bottoms of the grooves. The grooves are pref. formed at a depth greater than half the thickness of the panel, and up to 9/10 of the thickness, and have a trapezoid section with a width greater at the inlet end, formed by using blades of contrast cross-section.
