CA 2410653

A plurality of discrete packages (100) are manufactured from an indefinite length of gusseted packaging material (1). Each package (100) has an insert (9) inserted through an incision (7) in the packaging (1) which in use maintains a desired footprint of the package. Gaps (17) in welds (15) joining the bottom of the insert (9) to the packaging material (1) allow air to vent from between the insert (9) and the packaging material (1). Flaps (23) toward the rear of each package (100) join a leading package (100) to a following package (100a) by means of longitudinal welds (21) which allow gaps (22) for air to vent during the roll-up process.

L'invention concerne plusieurs emballages discrets (100) fabriqués à partir d'une longueur indéfinie de matériau d'emballage à soufflets (1). Chaque emballage (100) est doté d'un insert (9) inseré à travers une incision (7) dans l'emballage (1) qui maintient en cours d'opération une empreinte souhaitée de l'emballage. Des espaces (17) dans les soudures (15) reliant le fond de l'insert (9) au matériau d'emballage (1) permettent à l'air de passer entre l'insert (9) et le matériau d'emballage (1). Des rabats (23) orientés vers l'arrière de chaque emballage (100) assemblent un emballage principal (100) à un emballage secondaire (100a) au moyen de soudures longitudinales (21) permettant aux espaces (22) prévus de produire une aération au cours du processus d'emballage.
