Abstract
Foglio composito in Polivinilalcole a differenziata solubilità in acqua, comprendente un film (A), a ritardata solubilità in acqua, costituito da Polivinilalcole avente un grado di idrolisi di almeno 93; e un film (B), a rapida solubilità in acqua, costituito da Polivinilalcole avente un grado di idrolisi inferiore a 93. Il foglio composito trova vantaggiosa applicazione nella produzione di involucri protettivi di materiali infetti e/o inquinanti, in particolare per la copertura di recipienti igienico-sanitari, di facile e rapido smaltimento e distruzione negli scarichi fognari.
