Delfort has unveiled its latest advancement in food packaging technology with the introduction of thinbarrier 302, a specialty paper designed to offer robust protection for perishable items such as ice cream, chocolates, and sweets. This innovative product aims to serve as an alternative to traditional packaging materials, enabling the safeguarding of food quality during transportation and storage.
The thinbarrier 302 paper is notable for its exceptional barrier properties, including resistance to moisture, oxygen, aroma, and fat. Developed in collaboration with Henkel, this cold-sealing solution works seamlessly with compatible coatings to ensure that the taste, appearance, and texture of food products remain intact, even under challenging conditions.
One of the standout features of this paper is its resiliency; it boasts flex-crack resistance, rendering it capable of withstanding the rigors of handling and transportation. Notably, thinbarrier 302 contains no intentionally added per- and polyfluoroalkyl substances (PFAS) and is recyclable according to the CEPI method, aligning with contemporary sustainability goals.
Delfort has also emphasized the operational advantages of this product, highlighting a release coating that prevents the paper from sticking to itself during storage and processing. This characteristic is designed to facilitate smooth operations on packaging lines.
The efficacy of thinbarrier 302 is exemplified in its measured properties, with a moisture vapor transmission rate (MVTR) of less than 10 at 23°C and 85% humidity. This capability aims to prevent freezer burn, particularly for ice cream products, while its oxygen transmission rate (OTR) of less than 30 strives to preserve the flavours and aromas of a variety of foods, ensuring a delightful consumer experience.
In the wider context of sustainable packaging solutions, the industry is witnessing significant innovations. For example, Mondi’s thinnest barrier paper is set to be converted into recyclable bread bags, while Huhtamaki has gained recognition for its OmniLock Ultra Paper, a fully recyclable option intended to replace non-recyclable multi-layer laminates.
Delfort’s thinbarrier 302 represents a significant step forward in food packaging technology, combining functionality with sustainability in a manner that benefits both producers and consumers alike.
