The product efficiency of bags each with an end face part is increased. A panel webs is guided to be divided along a line of weakness of the panel web and to be folded along division edges of the panel web. This guiding of the first panel and temporary sealed sections cause a side gusset to be cut open along a line of weakness of the side gusset such that open surfaces are formed. After the forming of the open surfaces, an end face web is supplied to be superposed on folded parts of the panel web and the open surfaces of the side gusset.

Provided is a side-gusseted pouch that reduces occurrence of delamination in the vicinity of a lower end coupling portion of a side gusset film. A side-gusseted pouch in which in at least one of side gusset films on right and left sides, a lower side inclined edge portion includes a folding guide portion and a lower end side connecting portion that connects a lower end of the folding guide portion and a lower end coupling portion, and the lower end side connecting portion connects the lower end of the folding guide portion and the lower end coupling portion such that the lower end coupling portion is located below a first imaginary intersection point at which a central imaginary line passing through an upper end coupling portion and the lower end coupling portion intersects a folding imaginary line defined by the folding guide portion.

A quad-seal package has a front panel, back panel, first side panel, and second side panel formed from a recyclable packaging film. The recyclable packaging film includes a machine-direction oriented, polyethylene-rich exterior film and a polyethylene-based interior film. The quad-seal package, when containing a granular product, resists rupture when dropped according to ASTM D5276-98 test procedure A2.2.1 on the bottom of the package at a drop height of 91.4 cm (36 inches).

A packaged, sealed container system for stable storage of a formulation of an oxygen-sensitive pharmaceutical compound, the packaged, sealed container system comprising a primary container including therein a formulation of an oxygen-sensitive pharmaceutical compound, a secondary outer container comprising a first flexible sheet layer, an opposing second flexible sheet layer, and a seal disposed along a common peripheral edge of the first and second flexible sheet layers, such that the primary container is disposed between and enclosed by the first and second flexible sheet layers of the secondary outer container. An oxygen scavenger is also disposed between and enclosed by the first and second flexible sheet layers of the secondary outer container. The oxygen scavenger is in fluid communication with the contents of the primary container.
