Delfort, an Austria-based manufacturer of specialty paper, has introduced a thin barrier 302 specialty paper that ensures premium protection for ice cream, chocolates, candies and other temperature-sensitive items.
For this, Delfort partnered with Henkel, a German-based chemical company that deals in adhesives, sealants and functional coatings for industrial customers , to find the perfect cold seal coating solution.
Watch: In Pursuit of Lesser Water Footprint
With barrier properties including moisture, oxygen, aroma and fat resistance, Delfort said brands have a reliable paper packaging solution that ensures products remain fresh and protected. Paired with compatible cold seal coatings, the paper provides protection against external elements, ensuring the taste, appearance and texture of foods.
Despite its lightweight design, the paper is strong, with flex-crack resistance that withstands the demands of handling and transportation.
Boasting a low moisture vapour transmission rate (MVTR) of less than 10, measured at 23°C and 85% humidity, the paper prevents moisture from penetrating the packaging. The low MVTR keeps products dry and maintains their texture and quality. This prevents freezer burn that can degrade texture and flavour, especially in items like ice cream bars. The specially designed barrier ensures that frozen foods do not become icy or dried-out over time.

With a low oxygen transmission rate (OTR) value of less than 30, the barrier paper restricts oxygen from entering the package. This is essential for products as it preserve the natural aroma of the product and maintain sensory experience.
Dr Freddy E. Boscán, General Manager- PD innovation flexible coatings, Henkel, said, “Delfort’s barrier paper was optimally designed with a paper surface that makes it compatible with a range of cold seals from Henkel, each tailored for specific requirements of relevant flow pack structures. These cold seals promote circularity by being certified as recycling-compatible and enable sustainable packaging solutions that align with the industry’s shift towards a closed-loop economy.’’
