METHOD OF MANUFACTURING PASSIVE PACKAGING WITH IMPROVED ACTIVE, INTELLIGENT AND BIOACTIVE PROPERTIES THROUGH THE INCORPORATION OF POLYMERS OBTAINED BY ELECTROSPINNING TECHNIQUES
The invention in question relates to a method of manufacturing new materials and passive packaging with improved active, intelligent and bioactive properties, through the incorporation, in plastic matrices, of nanoreinforcements obtained by electrospinning techniques, said method comprising the following steps: dissolving or reducing the dry viscosity by heat of at least one polymer, electrospinning the solution or melt obtained, adding the electrospun fibres to a polymer to create a plastic concentrate or dress-enriched substance, and processing and shaping the concentrate or dress-enriched substance to produce a material for use in packaging or a packaging item. The invention also relates to the use of the products obtained by the manufacturing method.

NOVEL NANOCOMPOUND MATERIALS WITH INFRARED, ULTRAVIOLET AND VISIBLE ELECTROMAGNETIC RADIATION BLOCKING PROPERTIES AND METHOD FOR OBTAINING THEM
The invention in question relates to novel nanocompound materials which protect against infrared and ultraviolet-visible radiation, and to the method for obtaining said materials which comprises the following steps: reducing the size of the laminar particles by mechanical action, filtration, removal of organic material, removal of crystalline oxides and hard particles not modified, obtaining fine laminar material or laminar structures, pre-treating the laminar structures using precursors, and adding the product of the above steps, either in the liquid state or in the dry state, to a plastic matrix. The invention also relates to the use of said materials in various sectors of industry.

The invention relates to a method for producing intercalated nanocomposites from organic materials with laminar structures. The inventive method is characterised in that it comprises the following steps consisting in: reducing the size of the laminar particles and purifying same, pre-treating the natural and/or synthetic structures using precursors, intercalating modifiers into the laminar structure, adding the product resulting from the previous step in liquid form during the processing of a plastic matrix and/or precipitating the product resulting from the previous step in order to obtain a masterbatch, and incorporating the masterbatch into a plastic matrix using any plastic processing means.
