Food packaging has to do a lot at once. It needs a reliable barrier against moisture, grease and external factors, while staying strong in use. Yet many conventional solutions still rely on plastic coatings or multilayer structures, which complicate recycling and face growing regulatory pressure under EU packaging legislation.

That is why Kroonpak has developed a pilot burger box with a fibre-on-fibre approach. Using a Woodcell™ crystalline cellulose coating, it creates a paper-based, monomaterial structure that avoids conventional fossil-based plastic layers, delivers the barrier properties food service needs and supports paper recycling pathways.

An innovative, cellulose-based coating

Woodcell™ crystalline cellulose is a wood-derived barrier material developed by Fibenol. Applied as a functional coating on paperboard, it enables a monomaterial fibre-on-fibre structure. Unlike conventional polymer coatings, it integrates into the fibre matrix rather than forming a surface film. The pilot burger box concept is developed with Kroonpak as the packaging partner, with high-demand food-service use in mind.


Barrier performance

In essence, it is paper-on-paper approach, refreshingly simple in structure, yet powered by high-purity crystalline cellulose chemistry, offering the following barrier properties:
* Grease & oil resistance
* Light moisture protection
* Oxygen & air barrier
* Mineral oil barrier

This material is well suited to high-demand food-service takeaway formats and a broad range of food packaging applications.
