Abstract
The embodiments include a wide mouth gusseted package wherein four machine direction edge seals are formed on the film, and the zipper is applied in the transverse direction on the opposite side of the film from where the machine direction edge seals are formed. In the resulting package, the edge seals are at the exterior of the four corners of the package, and the resulting gussets can be folded inwardly or outwardly. The package may further include a sealing strip with a peel seal layer and a sealant layer whereby a hermetic package may be produced at higher production rates and lower productions costs.
