主权项

1. A pouch for storing a film comprising:
a laminate of at least one first layer and at least one second layer, and a cavity comprising a film which has been annealed to reduce stress-cracking of said film, said film comprising at least one polymer and at least one active, wherein said film exhibits less stress-cracking when annealed than when not annealed.
