With the Thinbarrier 302, the Austrian manufacturer Delfort is introducing a high-performance barrier paper for heat-sealing and cold-sealing applications for flexible food packaging. <\/strong><\/p>\n

Target groups include producers of frozen and chilled foods, confectionery and sugar confectionery, chocolate bars and cereals. \u201eOur new packaging paper weighs just over 60 grams and is therefore currently one of the lightest barrier securities on the market<\/strong>\u201c, says Peter Hackl, Head of Delfort's Packaging Division. The Thinbarrier 302 can be disposed of in waste paper and has a very good CEPI recycling score.<\/p>\n

\n

\u201eThanks to a combined oxygen, water vapour and grease barrier, the paper achieves the values of standard plastic films and is thin and light at the same time. We are therefore launching a new generation of barrier papers onto the market.\u201c<\/p>\n

Due to its improved tensile strength and tear resistance, the paper is particularly Favourable running and sealing properties on packaging machines that previously worked with film<\/strong>. \u201eOur product developers have given the new paper a high-performance application profile,\u201c says Hackl. A water vapour barrier of less than 10 grams per square metre\/day prevents moisture from penetrating the packaging. \u201eThis is important for dry snacks, for example, as they react very sensitively to fluctuations in humidity.\u201c Conversely also prevents moisture loss from the food,<\/strong> Texture and freshness are retained. The specially developed barriers also ensure that frozen food does not ice up and freezer burn does not occur.<\/p>

The oxygen barrier of Thinbarrier 302 is lower than that of commercially available plastic monofilms and prevents oxygen from penetrating the packaging. The new barrier paper is free from optical brighteners (OBA)<\/strong> and intentionally added per- and polyfluorinated chemicals (PFAS).<\/p>\n
