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. ## Claims ### Claim 1 A process of forming a package, including the steps of: providing a sheet of web with a first side and a second side; forming a plurality of seals on a first side of the web; after the step of forming a plurality of seals, providing a length of self-mating zipper profile on a second side of the web; and bringing edges of the sheet of web together and sealing the edges of the sheet of web together thereby forming sides of a package. ### Claim 2 (depends on 1) The process of claim 1 wherein the sheet of web is provided in a machine direction, the seals are oriented in the machine direction, and the length of self-mating zipper profile is provided a direction transverse to the machine direction. ### Claim 3 (depends on 2) The process of claim 2 wherein the seals are parallel to each other. ### Claim 4 (depends on 3) The process of claim 3 wherein the length of zipper profile is shorter than a width of the sheet of web. ### Claim 5 (depends on 4) The process of claim 4 wherein the step of bringing the edges of the sheet of web together results in the zipper being on the interior of the package. ### Claim 6 (depends on 5) The process of claim 5 wherein the step of bringing the edges of the sheet of web together results in the seals being on an exterior of the package. ### Claim 7 (depends on 6) The process of claim 6 wherein the package includes corners and wherein the seals are formed at the exterior of the corners. ### Claim 8 (depends on 7) The process of claim 7 wherein the plurality of seals includes four seals and wherein four corresponding corners are formed on the package. ### Claim 9 (depends on 8) The process of claim 8 wherein the package includes four walls. ### Claim 10 (depends on 9) The process of claim 9 wherein two of the four walls are gusseted walls. ### Claim 11 (depends on 10) The process of claim 10 wherein the gusseted walls can fold inwardly or outwardly. ### Claim 12 (depends on 11) The process of claim 11 the step of bringing the edges of the sheet together includes the step of bring longitudinal edges of the sheet together. ### Claim 13 (depends on 12) The process of claim 12 wherein the sheet of web is polymeric. ### Claim 14 (depends on 13) The process of claim 13 wherein the step of sealing the edges results in a fin seal. ### Claim 15 (depends on 14) The process of claim 14 wherein the step of providing the sheet of web includes providing the sheet of web from a roll. ### Claim 16 (depends on 6) A process of forming a package of claim 6 further including the steps of providing a sealant strip with a first layer comprising sealant material and a second layer comprising peel seal material; placing the sealant strip on the sheet of web; after the step of bringing edges of the sheet of web together, applying a first sealing bar thereby forming a top seal of the package. ### Claim 17 (depends on 16) The process of claim 16 wherein the step of placing the sealant strip on the sheet of web includes placing the sealant material against the sheet of web. ### Claim 18 (depends on 17) The process of claim 17 further including the step of sealing the sealant strip to the sheet of web. ### Claim 19 (depends on 18) The process of claim 18 further including the step of applying a second sealing bar to the sheet of web thereby forming a bottom seal of the package.
