Abstract
Przedmiotem zgłoszenia jest sposób wytwarzania wielowarstwowej folii na bazie skrobi termoplastycznej i przędzonego polilaktydu, który polega na tym, że w temperaturze 60,0°C – 85,0°C przez 8 - 25 minut, z szybkością 10 - 60 obrotów na minutę miesza się 55,0 – 63,0 cg/g skrobi o zawartości amylozy 10 - 35 cg/g oraz 30,0 – 34,0 cg/g plastyfikatora. Po 4 - 15 minutach mieszania wprowadza się jeszcze 3,0 – 15,0 cg/g oksydowanej sacharozy i kontynuuje mieszanie przez 4 - 17 minut. Uzyskaną mieszaninę poddaje się plastyfikacji w temperaturze z zakresu 90,0°C – 180,0°C i uzyskuje się skrobię termoplastyczną. TPS układa się na arkuszu elektroprzędzonego polilaktydu, prowadzi się prasowanie i uzyskuje folię dwuwarstwową. Grubość warstwy przędzonego polilaktydu w folii dwuwarstwowej wynosi 12 - 16 µm, a pozostałą część stanowi warstwa skrobi termoplastycznej o grubości 250 - 450 µm.
