Abstract
A product is packaged in a pressure-reclosable package comprising a multilayer film having a heat-sealable, pressure-reclosable inside layer. The inside layer contains a hyperbranched polyolefin having at least 70 side chain branches per 1000 carbon atoms and a density of up to about 0.885 g/cc, and/or an ethylene/alpha-olefin elastomer having a density of up to about 0.885 g/cc. The package is opened and a portion of the product removed, and a pressure-induced seal is used to re-close the package at a temperature of at least 11.degree. C. The reclosed package is then placed in an environment having a temperature of from about -50.degree. C to +1.degree. C., so that a cooled pressure-reclosed seal at least doubles in strength.
