Scientists at the Agronomy Faculty of Mendel University in Brno are creating bio-films made of polysaccharide-based materials, such as furcellaran and chitosan, which naturally break down in soil thanks to microbial activity. These sheets resemble standard office foil but swell when exposed to moisture, highlighting their biodegradable properties. The production process involves mixing the powdered materials with water and other additives to improve durability, flexibility, and thermal stability, after which the mixture is dried into thin sheets.

The films are enriched with phosphorus and potassium, enabling them to serve not only as protective covers but also as nutrient sources for plants. In experimental trials, they were formed into small “baskets” for seedlings, gradually decomposing while releasing nutrients. Early tests with lettuce and strawberries showed encouraging results, and further field trials are underway.

Researchers also see potential applications beyond agriculture. The bio-films can be shaped into capsules, spheres, or composites with beneficial organisms, opening possibilities in pharmaceuticals, packaging, and even extraterrestrial use. Overall, this innovation could offer an eco-friendly alternative to plastics while reducing environmental impact.
