The invention relates to tough and moldable biodegradable polymer compositions with high impact resistance, elongation, and mechanical strength. The compositions comprise biodegradable thermoplastic polymers, biobased plasticizers, inorganic fillers, organic acids and optionally other additives. The compositions exhibit an excellent balance between elongation-at-break greater, tensile strength, impact strength, rigidity, and melt flow index while maintaining full biodegradability within 180 to 365 days. The biodegradable resins can be produced using traditional polymer processing equipment such as twin screw extruders or batch mixers. The resins can be formed into rigid parts and end products using traditional techniques including injection molding, thin-walled injection molding, compression molding and thermoforming.

0000 The present invention relates to a method and apparatus for cooking food items, such as meats and vegetables, in a more efficient and faster manner while maintaining high product yield. The invention utilizes steam cooking in a stepped process, which allows for even cooking and browning in a single cycle. The cooking apparatus includes a flavoring mechanism that enables steam or compressed air to pass through flavor pods containing seasonings such as oils, salts, and spices. This flavored steam circulates within the cooking chamber, infusing the food with the desired flavors. In one embodiment, flavor pods positioned above the food release seasoning at specific times or temperatures, allowing for optimal flavoring before the final cooking stage. Another embodiment includes a film wrapped around the food that disintegrates at a predetermined temperature, releasing seasoning onto the food at the ideal cooking stage. These features ensure efficient and precise flavor infusion during cooking.

Fibre-based food-contact packaging carries a PFAS-free, repulpable barrier coating whose grease and moisture barrier is retained across folds and creases, where such coatings normally micro-crack and leak. Four complementary inventions are described. A self-healing coating re-seals crease-induced micro-cracks, autonomously or under a mild non-registered stimulus such as heat from hot food contents, recovering the barrier to a quantified post-heal retention. A single uniform coating of high-aspect-ratio platelets in a ductile elastomeric matrix, loaded below a percolation-embrittlement threshold with an engineered slip interface, is simultaneously high-barrier and crease-tolerant. A coating whose mechanical property varies in register with the fold-line layout places compliant zones on the fold lines and high-barrier zones between them. Crease or substrate engineering keeps coating strain below its crack-onset strain. The approaches may be used alone or in combination. ug u g u s e d a l o n e o r i n c o m b i n a t i o n u g u s e d a l o n e o r i n c o m b i n a t i o n 314316 324 326 FIG. 1FIG. 1 326324314316 ug u g u g
