Ifilimu ye-multilayer coextrusion
Ukuze kwandiswe ubomi beshelufu yokutya, amayeza kunye nezinye izinto, uninzi lwezinto zokutya kunye nezixhobo zokupakisha iziyobisi ngoku zisebenzisa iifilimu ezihlanganisiweyo ze-multi-layer co-extrusion.Okwangoku, zimbini, zintathu, zintlanu, zisixhenxe, alithoba, kunye neshumi elinanye umaleko wezinto zokupakisha ezihlanganisiweyo.Ifilimu ye-multi-layer co-extrusion ifilimu ekhupha izinto ezahlukeneyo zeplastiki ukusuka kwifa enye ngexesha elinye ngokusebenzisa iziteshi ezininzi, ezinokunika ukudlala kwiinzuzo zezinto ezahlukeneyo.
Ifilimu edityanisiweyo ye-multi-layer co-extruded iqulunqwe ikakhulu yi-polyolefin.Okwangoku, izakhiwo ezisetyenziswa ngokubanzi ziquka: i-polyethylene / i-polyethylene, i-polyethylene / i-vinyl acetate copolymer / i-polypropylene, i-LDPE / i-adhesive layer / EVOH / i-adhesive layer / LDPE, i-LDPE / i-adhesive layer / EVOH / EVOH / i-adhesive layer / LDPE.Ubuninzi bomaleko ngamnye bunokulungiswa yinkqubo ye-extrusion.Ngokuhlengahlengisa ubukhulu boluhlu lwesithintelo kunye nokusetyenziswa kwezixhobo ezahlukeneyo zomqobo, ifilimu eneempawu ezahlukeneyo zomqobo inokuqulunqwa ngokuguquguqukayo, kunye nezinto zokutywinwa kobushushu nazo zingatshintshwa ngokuguquguqukayo kwaye zabelwe ukuhlangabezana neemfuno zokupakisha ezahlukeneyo.Le nxalenye ye-multilayer kunye ne-multi-function co-extrusion ikhompawundi yindlela ehamba phambili yokuphuhliswa kwezinto zefilimu zokupakisha kwixesha elizayo.
