Resumen de: AU2026223297A1
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

Thermoplastic starch-based materials formed as a reactive extrusion product from one or more starches, plasticizers, with the addition of a diacid, diglycidyl ether, silicone and/or a glyceride additive added during gelatinization of the starch and plasticizer, before blending of such starch-based polymeric material with any other polymer (e.g., polyester biopolymers, polyolefins, polyamides, etc.). Silicones, where added, may alternatively be added after formation of the thermoplastic starch, e.g., as part of a masterbatch, when blending with another polymer. Addition of silicone reduces glycerin migration and smoke generation, particularly when processing such compositions to form nonwovens. Addition of glycerides (e.g., triglycerides) can increase hydrophobicity of the resulting starch-based polymeric material. Addition of the diacid can reduce molecular weight, while diglycidyl ether addition can build such molecular weight back up, resulting in a narrower molecular weight distribution, and improved processability of the resulting starch-based polymeric material, particularly for nonwoven applications.
