Abstract
In some embodiments a Stand Up Pouch (SUP) is prepared using a polyethylene structure having a first web and a second web. The webs are laminated together to form the polyethylene structure that is used to prepare the SUP. One web contains a layer of recycled polyethylene (r.PE). In some instances, the use of r.PE has been observed to reduce the effectiveness of the sealant layer of the overall structure. In some embodiments, the SUP disclosed herein has a two layer sealant system to mitigate this problem.
