摘要:
A polymeric film and method for overcoming the problem of "pinholes" created in filled pouches by the harmonic motion occurring during transport of the filled pouches. The polymeric film composed of from about 5% to about 95% by weight of a first polymeric material having an elongation at break of more than about 500% in the machine direction and more than about 600% in the transverse direction, and from 5% by weight to about 95% by weight of a second polymeric material having a density of at least about 0.915 g/cm.sup.3 and selected from the group consisting of polyethylene and ethylene copolymers. The first polymeric material includes a very low density linear ethylene interpolymerized from ethylene and at least one alpha-olefin in the range of C.sub.3 -C.sub.10. The film may be fabricated into pouches and the pouches stacked for transportation.
