Filed:

Jun 5, 2003

Appl. No.:

10/455055

Inventors:

Paul E. Hansen - Lake Elmo MN, US
John W. Rovang - New Ulm MN, US
Nathan K. Hagen - Austin TX, US

International Classification:

B65D005/54

US Classification:

428 362, 428 364, 428365, 428401, 428516

Abstract:

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 μm to about 7. 0 μm. 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.

Paul Hansen - Lake Elmo MN, US
John Rovang - Savage MN, US
Nathan Hagen - Austin TX, US
Charlene Thill - Chanhassen MN, US

International Classification:

B65D 25/08

US Classification:

206219000

Abstract:

A rupturable seal includes a first and second thermoplastic polymer layer and a third continuous polymer layer between the first and second polymer layers. The third polymer layer forms a first physical polymer blend with the first layer, and forms a second physical polymer blend with the second layer. The third layer can include a continuous fibrous strip of nonwoven polymeric microfibers, which may melt within a sealing region. Methods of making such seals and multi-compartment containers comprising such seals are disclosed. Applications for food storage and preparation and other diverse end uses are disclosed.
