<p>An at least two-layer film (10) for making fatigue crack resistant pouches (34-46, 52-58) is disclosed, with the film having an average resin density of less than about 0,918 g/cm3 and including at least first (12) and second (14) polymeric layers. A method of handling flowable material (28) in such pouches which reduces the probability of forming vibration fatigue cracks in the pouches, and a test method for evaluating the likelihood that a pouch will develop a material fatigue crack defect when transported are also disclosed.</p> |
