Ecological chip card, has intermediate layers made of biodegradable material, and active surface layer made of argillaceous nanomaterials, where intermediate layers have specific elasticity and thickness higher than specific millimeters

摘要

The card has a core material (20) with multicolor and/or transparent intermediate layers, where the core material has certain thickness. The layers are made of biodegradable material composed of a binder e.g. polylactic acid, and poly-epsilon-caprolactone based load obtained from vegetable base e.g. maize, sugarcane, sweet potato or cowberry. An active surface layer is made of argillaceous nanomaterials with a grain size of 5-10 nano meters. The intermediate layers have a thickness higher than 0.03 millimeters and an elasticity attaining 6000 pounds per square inch (psi).
