Abstract
Przedmiotem wynalazku jest sposób otrzymywania pieciowarstwowej folii poliolefinowej typu stretch zwlaszcza folia plaska. Sposób otrzymywania pieciowarstwowej folii poliolefinowej typu stretch z wykorzystaniem, jako produktów wyjsciowych, liniowego polietylenu malej gestosci, liniowego polietylenu bardzo malej gestosci jak równiez metalocenowego liniowego polietylenu malej gestosci i stosowaniem wytlaczarek slimakowych zasilajacych glowice szczelinowa charakteryzuje sie tym, ze do wytlaczarki podajacej surowiec na pierwsza warstwe stanowiaca 10 do 12% grubosci wytworzonej folii wprowadza sie kopolimer etylenu z n-heksenem o masowym wskazniku szybkosci plyniecia MFR od 1,0 do 6,0 g/10min., korzystnie 4,0 g/10 min., do nastepnej wytlaczarki stanowiacej o skladzie drugiej warstwy tej folii o grubosci wynoszacej 28 do 32% jej grubosci koncowej wprowadza sie kopolimer etylenu z n-heksenem o masowym wskazniku szybkosci plyniecia MFR od 1,0 do 6,0 g/10 min., korzystnie 4,0 g/10 min. o udziale procentowym 20 do 80% masowych korzystnie 50% masowych, z kopolimerem etylenu z n-heksenem otrzymanym przy udziale katalizatorów metalocenowych, o masowym wskazniku szybkosci plyniecia MFR od 1,0 do 6,0 g/10 min. korzystnie 4,0 g/10 m, z kolei dla trzeciej warstwy stanowiacej 14 do 18% grubosci folii do wytlaczarki wprowadza sie tak jak dla pierwszej warstwy kopolimer etylenu z n-heksenem o takim samym wskazniku szybkosci plyniecia. Czwarta warstwa stanowiaca 28 do 32% grubosci folii jest wytworzona z kopolimeru etylenu z n-heksenem o masowym wskazniku szybkosci plyniecia MFR od 1,0 do 6,0 g/10 min. o udziale procentowym 20 do 80% masowych, korzystnie 60% masowych z polipropylenem o masowym wskazniku szybkosci plyniecia MFR od 2,0 do 6,0 g/10 min. o udziale procentowym 80 do 20% masowych, korzystnie 40% masowych a piata warstwa stanowiaca 10 do 12% grubosci folii bedzie wytworzona z kopolimeru etylenu z n-heksenem o masowym wskazniku szybkosci plyniecia MFR od 1,0 do 6,0 g/10 min. przy udziale procentowym 40 do 95% masowych, korzystnie 80% masowych, z kopolimerem etylenu z n-heksenem otrzymanym przy udziale katalizatorów metalocenowych o masowym wskazniku plyniecia MFR od 1,0 do 6,0 g/10 min. i udziale procentowym 60 do 5% masowych korzystnie 20% masowych, przy czym wymienione surowce sa podawane z wytlaczarki do glowicy. Zastosowano temperature glowicy szczelinowej oraz rozdzielacza 260°C.
