Abstract
Przedmiotem zgłoszenia jest sposób wytwarzania opakowań z polipropylenowej folii spienionej przeznaczonych do dań na wynos, który charakteryzuje się tym, że recyklat polipropylenu PP w postaci przemiału lub granulatu o wskaźniku szybkości płynięcia 0,2 g/10 min do 10 g/10 min przed procesem wytłaczania poddaje się procesowi dekontaminacji przez podgrzewanie w przepływie gorącego powietrza do temperatury od 60°C do 100°C przez 1 do 10 godzin, pod obniżonym ciśnieniem od 1000 do 0,01 mbar lub w przepływie gazu obojętnego 0,1 l/h/kg – 0,5 l/h/kg surowca, po czym surowiec po dekontaminacji chłodzi się do temperatury poniżej 60°C i kieruje do głównej wytłaczarki jedno- lub dwuślimakowej.
