Across the food industry, more companies are rethinking how they protect their products while meeting rising expectations for recyclability. In the bakery and cereal sector, the shift toward sustainable materials is gaining massive momentum. Driven by consumer demand for plastic-free options and tightening regulations like the EU’s Packaging and Packaging Waste Regulation (PPWR), brand owners are searching for solutions that balance high-performance protection with environmental responsibility.
Tailored protection for bakery ingredients
When evaluating new packaging materials, the conversation starts with product protection. Bakery ingredients have diverse protection needs. While products such as vanilla sugar and dessert creams can be packaged with relatively low barrier materials, ingredients containing nuts, seeds, or fats require stronger protection against oxygen, water vapour, grease, and mineral oil to preserve quality and shelf life.
To address varying protection needs, Sappi has developed a comprehensive portfolio of functional papers that combine sustainability with tailored barrier performance across a wide range of bakery applications.
- High Barrier solutions: Products like Guard Pro OHS provide outstanding protection against oxygen, water vapor, and mineral oil (MOSH/MOAH), making them ideal for dried fruits, protein powders, and premium powder creams.
- Medium Barrier solutions: The barrier paper Guard MS are specifically tailored for products such as muesli, seeds, and bread mixes.
- Sealable Paper solutions: The Seal range, including Seal Silk, offers superior heat sealability and moisture barriers for applications requiring low barrier, including candies and secondary packaging.
Performance without major reinvestment
One of the most significant concerns for brand owners is whether these new materials can run on existing packaging lines. While plastic films are often perceived as more flexible and robust during processing, today’s functional papers are engineered to deliver comparable performance with only minor adjustments.
In most cases, switching to paper-based packaging involves fine-tuning operating parameters such as web tension, sealing temperature and sealing pressure. Modern packaging equipment can typically accommodate these adjustments, enabling paper solutions to achieve performance levels comparable to conventional plastic packaging.
To support a smooth transition, Sappi’s application engineering experts work closely with packaging machine manufacturers, converters and brand owners to validate performance under real operating conditions and optimise machine settings for reliable, efficient production.
A foundation of recyclability and sustainability
The primary driver for the move toward functional papers is recyclability. Unlike many plastic-based laminates that end up in mixed waste, Sappi’s functional papers are mono-materials that can be recycled directly in the paper waste stream. This alignment with the paper recycling stream simplifies disposal for consumers and helps brands prepare for future legal requirements.
Furthermore, sustainability begins at the source. Sappi uses wood-based raw materials from sustainably managed forests, with European mills holding both FSC and PEFC Chain of Custody certifications. This ensures that every step of the supply chain is transparent and responsible.
