Abstract

A food bag (4) comprising a bag body (8) extending from a lower closed bottom (12) to an upper opening (16), so as to delimit a containment compartment (20), at least one handle (24) arranged at said upper opening (16) and being fixed to the bag body (8) at its opposite locking ends (28,32), at least one closure strip (36) having a fixed end (40) at a first side (44) of the bag body (8) and a movable end (48) projecting towards a second side (52) of the bag body (8) opposite the first side (44). The movable end (48) is foldable, in a closed configuration, towards said second side (52) of the bag body (8), covering said upper opening (16), the closure strip (36) extending between said first and second sides (44,52) of the bag body (8) so as to prevent access to the containment compartment (20) in said closed configuration. Said at least one closure strip (36) is made at least partially of transparent, semi-transparent or translucent material and/or the bag body (8) comprises at least one window (100) made of transparent, semi- transparent or translucent material.

Abstract

Handle-forming machine for shaping and attaching strap handles (Μ' ) to bags or carrier bags, and/or to continuous rolls of paper (N) to make bags or carrier bags, said strap handles (Μ' ) being formed by folding substantially into a U shape at least one strip or strap (M). The handle-forming machine comprises at least one carousel (G) rotating around a main shaft (Gx), said carousel (G) in turn comprising one or more cradles (C) for gripping and folding the straps (M). Advantageously each cradle (C) rotates around a main shaft (Gx) at least from a feed station (1) of said strap/s (M), to a folding station (4) into a U shape of each strap (M) and to a loading station (6) of the folded strap (Μ' ), for attachment to the bag or to the continuous roll of paper (N) which the bag will be made from. Moreover the cradle also rotates around its own axis (Cx) radial to the main shaft (Gx), to rotate the position of the relative strap (M) between the folding (4) and loading (6) feed stations ( 1 ).
