Claim 22:
23. The method of claim 20, further comprising:
a) blending a transmission polymer with at least one additive to form first resin pellets;
feeding the first resin pellets into a first extruder; and
melting the resin pellets to provide the molten transmission polymer,

b) blending a barrier polymer with at least one additive to form second resin pellets;
feeding the second resin pellets into a second extruder, and
melting the second resin pellets to form the molten barrier polymer;

c) blending a sealant polymer with at least one additive to form third resin pellets;
feeding the third resin pellets into a third extruder, and
melting the third resin pellets to form the molten sealant polymer;

d) blending a first tie polymer with at least one additive to form fourth resin pellets;
feeding the fourth resin pellets into a fourth extruder, and
melting the fourth resin pellets to form the first molten tie polymer, and

e) blending a second tie polymer with at least one additive to form fifth resin pellets;
feeding the fifth resin pellets into a fifth extruder; and
melting the fifth resin pellets to form the second molten tie polymer.
