Zusammenfassung:	Branched polyethylenes of density up to about 0.875 g/cc are used as a component in articles that can be pressure-sealed and unsealed repeatedly. Such articles include multilayer films that contain the branched polyethylene and another thermoplastic and pressure-resealable closures comprising a sealing surface that comprises the branched polyethylene and a sealing surface that comprises a thermoplastic. The multilayer film and closures are particularly useful in packaging, especially plastic packaging, such as bags, pouches, and vacuum skin packaging, to package a large variety of goods.
