Abstract:
1. A multilayer barrier film comprising: a. a first layer comprising a high permeable material having a moisture vapor permeability greater than about 40 g-mil/100 in b. a second layer directly adjacent to the first layer comprising EVOH; c. a first region defining a third layer in direct contact with the second layer comprising 1 to 5 distinct sublayers comprising low permeable materials having moisture vapor permeability of less than about 20 g-mil/100 in d. a fourth layer comprising EVOH; e. a second region defining a fifth layer in direct contact with the fourth layer comprising 1 to 5 sublayers comprising very low permeable materials having a moisture vapor transmission rate of less than about 5 g/100 in
