The invention relates to a process for obtaining a food packaging which provides the preservation of the food characteristics and prolongs the validity term thereof. According to the invention, the process consists in preparing, in a first stage, a composite of titanium dioxide modified with 0.10...0.15% Au and, possibly, with nitrogen and 0.5...3% Ag or titanium dioxide-silicon dioxide mixture modified with 0.5...3% Ag, to be added to a polypropylene base and cellulose, respectively, after which, in a second stage, the mixture is processed in a manner known per se, to result in a package as a bottle or, possibly, a sheet of paper. Invenţia se referă la un procedeu de obţinere a unui ambalaj alimentar care asigură conservarea caracteristicilor alimentelor şi le prelungeşte durata de valabilitate. Procedeul conform invenţiei constă în prepararea într-o primă fază a unui compozit de dioxid de titan modificat cu 0,10...0,15% Au, eventual, cu azot şi 0,5...3% Ag, respectiv, mixt dioxid de titan-dioxid de siliciu modificat cu 0,5...3% Ag, care se adaugă la o bază de polipropilenă, respectiv, celuloză, după care, în a doua fază, amestecul se prelucrează în sine cunoscut, rezultând un ambalaj sub formă de flacon, eventual coală de hârtie.
