Multi-Layer Plastic Casing With A Porous Food Contact Side Suitable For Transferring Food Additives
Patent No. EP4159428 (titled "Multi-Layer Plastic Casing With A Porous Food Contact Side Suitable For Transferring Food Additives") was filed by Kalle on Sep 28, 2022. The application was issued on Nov 20, 2024.
Patent Summary
Food casing with a porous inner layer that absorbs and releases food additives like liquid smoke for even flavoring. A hydrophilic polymer mixed with polyamide creates interconnected pores, allowing rapid absorption and quick release of polar substances. The casing uses multiple coextruded layers: a porous layer, a carrier layer, and a water-vapor barrier layer. Chemical foaming agents generate the pores during extrusion, while additives improve melt strength and adhesion. This design ensures uniform absorption without surface defects, preventing uneven coloring or spotty flavor distribution.
