Mondi has collaborated with Polish seasoning manufacturer Prymat to develop a recyclable paper-based packaging solution designed to preserve the quality and aroma of spices while improving sustainability performance.
The new solution uses Mondi’s re/cycle FunctionalBarrier Paper Ultimate, a high-barrier paper containing more than 80% paper content. The material is engineered to provide protection against oxygen, moisture and grease—key factors in maintaining the freshness, flavour and colour of spices. Traditionally, spice packaging has relied on multilayer plastic or aluminium-based laminates to achieve comparable barrier properties, which can present recycling challenges.
According to the companies, the new paper-based structure has been designed to be recyclable within existing paper waste streams, in line with CEPI testing methods. The development follows a two-year collaboration focused on balancing barrier performance with recyclability and production efficiency.
Mondi stated that the material delivers ultra-high barrier performance while remaining compatible with Prymat’s existing filling lines, allowing implementation without additional investment in new machinery. The paper-based packaging also supports high-quality printing, maintaining shelf appeal for retail distribution.
The companies indicated that internal assessments show a lower carbon footprint compared to conventional multilayer alternatives, although specific figures were not disclosed.
The introduction of the recyclable high-barrier paper packaging reflects ongoing efforts within the food sector to reduce reliance on complex laminates while maintaining product protection standards. For spice manufacturers, where aroma retention and moisture resistance are critical, the development highlights the technical progress being made in fibre-based flexible packaging solutions.
