The users of this app are reminded that permeation performance is only one of a number of material properties important to the final package. Other parameters that need to be considered in selecting the optimal material(s) for a package include clarity, color, processability, cost, availability, consumer preference, regulatory restrictions, etc. This App is not intended to be used to advertise or recommend one producers materials over another. It is intended to be an objective assessment of the permeation of selected gases through these materials. Thus, all material properties included in the M-RULE Container Performance Model for Beverages have been critically and independently evaluated for accuracy. While specific resins may be identified by their trade names, this should not be considered an endorsement of any particular companys products.
