| abstract |
In order to obtain diverse examples of such biopolymeric materials, use is made of xanthan, as biopolymeric matrix, either alone or as a component of the matrix, optionally in combination with plasticizers and/or dispersants, defoamers, fillers and/or nanofillers and, optionally, salts, emulsifiers, antihumectants, thermal and dimensional stabilizers, preservatives, dyes, other additives, pharmacologically active substances, or a combination of all or some thereof. The compositions are preferably prepared by solubilization or dispersion, in liquid phase, or melting, in solid phase. Finished or semi-finished products and materials are obtained that are biodegradable, optionally edible, and preferably disposable. The methods used are casting, extrusion, stretch blow moulding, thermoforming processes, rotational moulding, injection moulding, print-up and spread coating to produce packaging, personal hygiene items, and medical, odontological, agricultural and other products. |
