<p>The sealability of a thermoplastic, mono- or multi-layer film having an irradiated sealing layer comprising a polyethylene and/or an ethylene-α-olefin copolymer with a density ≥0.915 g/cm3 is improved by corona treating said sealing layer. The integrity of the obtained sealed container is maintained under pasteurising or cook-in conditions.</p> |
