Abstract

Przedmiotem zgłoszenia jest sposób wytwarzania folii spożywczej, który charakteryzuje się tym, że folia jest współwytłaczana z rozdmuchem rękawa i składa się z nie mniej niż pięciu warstw wytłaczanych metodą rozdmuchu. W sposobie tym każda z warstw folii zasilana jest osobną wytłaczarką, które zasilają głowicę krzyżową, w której są łączone i wytłaczane jako jedna folia w postaci rękawa chłodzonego powietrzem, gdzie pierwsza warstwa to polietylen niskiej gęstości (LDPE)z udziałem surowca w warstwie 100% wagowych, druga warstwa składa się z polietylenu niskiej gęstości (LDPE) w ilości 50% wagowych, kopolimeru etylenu i octanu winylu (EVA)w ilości 10 - 40% wagowych i kopolimeru etylenu i alkohol winylowy (EVOH) w ilości 10 - 40% wagowych, trzecia warstwa z udziałem surowca w warstwie poliamidu 6 (PA6) w ilości 93 - 98% wagowych oraz octan celulozy (CA) w ilości 2 - 7% wagowych. Warstwa czwarta składa się z polietylenu niskiej gęstości (LDPE) w ilości 50% wagowych , kopolimeru etylenu i octanu winylu (EVA) w ilości 10 - 40% wagowych oraz kopolimeru etylenu i alkoholu winylowego (EVOH) w ilości 10 - 40% wagowych. Warstwa piąta składa się z polietylenu niskiej gęstości (LDPE) w ilości 100% wagowych. Temperatura przetwórcza głowicy krzyżowej wynosi 250°C.The subject of the application is a method for producing food film, which is characterized in that the film is coextruded with the blow molding of the sleeve and consists of not less than five layers extruded by blow molding. In this method, each of the film layers is fed by a separate extruder, which feeds the cross head, in which they are combined and extruded as one film in the form of an air-cooled sleeve, where the first layer is low-density polyethylene (LDPE) with a 100% by weight raw material , the second layer consists of low density polyethylene (LDPE) in the amount of 50% by weight, ethylene vinyl acetate copolymer (EVA) in the amount of 10 - 40% by weight and ethylene copolymer and vinyl alcohol (EVOH) in the amount of 10 - 40% by weight, the third layer with raw material in the polyamide 6 (PA6) layer in the amount of 93 - 98% by weight and cellulose acetate (CA) in the amount of 2-7% by weight. The fourth layer consists of low density polyethylene (LDPE) in the amount of 50% by weight, ethylene vinyl acetate copolymer (EVA) in the amount of 10 - 40% by weight and ethylene vinyl alcohol copolymer (EVOH) in the amount of 10 - 40% by weight. The fifth layer consists of low density polyethylene (LDPE) in an amount of 100% by weight. The processing temperature of the cross head is 250 ° C.
