Biodegradable substrates are designed to naturally decompose under specific composting conditions, minimizing long-term environmental impact. These include bio-based papers, starch- or PLA-based films, and other compostable boards. They are often used for short-term applications and require compatible inks or coatings to maintain biodegradability. Certification (e.g., EN 13432) is key for sustainability claims.
Applications:
Eco-labels, short-term event signage, packaging prototypes, and disposable graphics.
