Las propiedades permanecen sin cambios durante el per\u00edodo de almacenamiento. Despu\u00e9s de su uso, los productos pueden descomponerse en sustancias inofensivas en condiciones ambientales naturales. Los principales campos de aplicaci\u00f3n de los pl\u00e1sticos degradables incluyen mantillo agr\u00edcola, diversos tipos de bolsas de embalaje de pl\u00e1stico, bolsas de basura, bolsas de compras
