PACKAGING PROCESS UTILIZING RECLOSABLE PACKAGE HAVING PRESSURE-INDUCED RECLOSE SEAL WHICH BECOMES STRONGER AT LOW TEMPERATURE |
摘要 |
<p>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 ethClen5/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 °C. The reclosed package is then placed in an environment having a temperature of from about -50°C to +10°C, so that a cooled pressure-reclosed seal at least doubles in strength.</p> |
