Abstract
Multiple layer coextruded films of high melting temperature polymers and polyethylene permit the effective ultrasonic sealing of wet, contaminated sealing surfaces to produce water tight, leak free packages for wet product. The slurry filled packages may be used and stored at room temperatures, or may be advantageously frozen for long term storage and transport while frozen.
