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. Un produit est emballé dans un emballage à fermeture pression comprenant un film multicouche dont la couche intérieure est thermocollable et à fermeture pression. La couche intérieur contient une polyoléfine hyper-ramifiée, présentant au moins 70 ramifications latérales en chaîne pour 1000 atomes de carbone et une densité pouvant atteindre environ 0,885 g/cc et/ou un élastomère ethClen5/alpha-oléphine ayant une densité pouvant atteindre environ 0,885 g/cc. L'emballage est ouvert et une partie du produit est retirée, et une fermeture pression hermétique est utilisée pour refermer l'emballage à une température d'au moins 11 °C. Le paquet refermé est en suite placé dans un environnement dont la température est à peu près comprise entre -50°C et +10°C, de sorte que la fermeture pression hermétique
