More Information
Summary:The invention relates to a thermochromic material comprising at least one biopolymer, at least one natural dye and at least one reaction medium, selected from the group of fatty acids and derivatives thereof, gallic acid and derivatives thereof and mixtures thereof. The thermochromic material according to the invention is completely based on non-toxic, natural products. Processing into materials or molded articles can occur, according to the invention, by means of conventional extrusion technology in the form of flat film, blown film or sheets or multi-wall sheets. The thermochromic material can be used in particular in the food industry and medical technology.
