Nonwoven plastic pouch separator

摘要

A rupturable seal comprising a film of a first polymer, a film of a second polymer and a sealing interlayer. The sealing interlayer has a melting point higher than the melting points of either the first polymer or the second polymer and comprises a plurality of micro-fibers each having an average effective fiber diameter from about 2.5 mum to about 7.0 mum. Fusion bonding of films of the first polymer and the second polymer to either side of a sealing interlayer produces a rupturable seal having a frangible interface including portions thereof wherein the first polymer contacts the second polymer. The rupturable seal parts at the frangible interface by application of force causing a gap and separation of the first film from the second film.
