Abstract
Sposób wytwarzania folii sześciowarstwowej metodą współwytłaczania z rozdmuchem na standardowym ekstruderze trzywarstwowym, charakteryzujący się tym, że mieszaninę o składzie 65% polietylenu niskiej gęstości LDPE, 25% liniowego polietylenu niskiej gęstości mLLDPE C6 i 10% inicjatora adhezji, stanowiącego dodatek zawierający polibuten o stężeniu 50% lub kopolimer propanu z 11% udziałem polietylenu niskiej gęstości LDPE, poddaje się rozdmuchowi o współczynniku BUR 2,8, prowadzi proces ekstruzji z prędkością liniową folii 17 m/min, po czym wstępnie schładza do temperatury od 55 do 60°C, poddaje laminacji za pomocą niechłodzonego kalandra odciągu górnego pracującego przy ciśnieniu od 7 do 9 atm., następnie schładza folię do temperatury otoczenia i nawija na tuleje papierowe lub PCV.A method of producing a six-layer film by co-extrusion on a standard three-layer extruder, characterized by the fact that the mixture is composed of 65% low density polyethylene LDPE, 25% linear low density polyethylene mLLDPE C6 and 10% adhesive initiator, which is an additive containing 50% polybutene or a propane copolymer with 11% low-density polyethylene LDPE, is blown with a 2.8 BUR coefficient, extruded at a linear speed of 17 m / min, then pre-cooled to a temperature of 55 to 60 ° C, laminated using an uncooled upper exhaust calender working at a pressure of 7 to 9 atm, then cools the film to ambient temperature and winds on paper or PVC sleeves.
