Abstract: Multilayer film structures are disclosed having a first layer of polymer sealant material, a second layer comprising a frangible bond layer, and a third layer comprising an adhesive or polyolefin. The first layer comprises from about 1% to about 10% of the total thickness of the multilayer film structure, has a maximum thickness of about 0.25 mils. and has a thickness uniformity deviation of less than about 20% of the average thickness of the first layer.
