Flong paper for packing food stuff e.g. fruit, has transversal wall articulated on two horizontal walls by two parallel folding lines, and openings cut in corresponding position at base of transversal and longitudinal walls

摘要

The paper has a transversal wall articulated on two horizontal walls by two parallel folding lines. Another transversal wall has two parts articulated on longitudinal walls (2) by perpendicular folding lines that join two flaps on a base of the walls. The walls have respective parts protruding towards the top. Openings (9) are cut in corresponding position at the bases and in the flap to receive blocking and stacking units. Independent claims are also included for the following: (a) a process of fabrication of the flong paper (b) a package of type tray or sleeve pack.
