Abstract

A bottom-gusseted package comprises a package body, and a bottom gusset positioned transversely of a longitudinal axis of the package body. Formation of the bottom-gusseted package is effected by positioning individual sleeves transversely of the longitudinal axis of a flexible web which forms the package body. During package formation, the flexible web is cut to form individual packages, with each individual sleeve positioned to form a bottom gusset in a respective package. Cooperating heat-sealing jaws, including cooperating U-shaped sealing surfaces, act to integrate and seal each individual sleeve with the flexible web to form the bottom gusset of each package, with the heat-sealing jaws preferably configured to include cooperating top sealing surfaces for simultaneously forming a top seal in an adjacent one of the packages.
