Ifilimu yoLula ineenzuzo zokuqina, ukuchasana kwempembelelo, ukungafihli kunye nokuzincamathela.Ingaba isetyenziselwa ukupakishwa okuhlangeneyo kweemveliso okanye iipallets zempahla, inokuthintela ukufuma, uthuli kunye nokunciphisa abasebenzi, ukuphucula ukusebenza kakuhle, kunye nokufezekisa injongo yokukhusela iimveliso kunye nokunciphisa iindleko.Ifilimu eyoluliweyo luhlobo lwemathiriyeli yokupakisha esetyenziselwa ukuhlanganisa iimpahla.Isici sayo esiyingqayizivele kukuba inokusebenzisa izixhobo zokwelula ngoomatshini okanye ivelise ngesandla uxinzelelo lwe-deformation.Indlela yokulawula i-viscosity yefilimu eyoluliweyo?

Kukho izinto ezininzi zefilimu yokwelula, eyona nto ixhomekeke kwintsimi yesicelo somkhiqizo, ngoko ke ukuba ufuna ukulawula i-viscosity yefilimu elula, unokusebenza nzima kwizinto eziphathekayo.Ayizizo zonke i-C4-LLDPE ezinokusetyenziselwa ifilimu eyolula.Izixhobo ze-C6 kunye ne-C8 zihlala zisetyenziswa ngenxa yokukhululeka kwazo.

Ubushushu buya kuchaphazela i-viscosity yefilimu elula.Ngokuqhelekileyo, sibeka imveliso kwindawo ye-15 ukuya kwi-25 degrees.Ukuba iqondo lokushisa lidlula ama-30 degrees, i-viscosity iya kwanda;ukuba ingaphantsi kwe-15 degrees.Ngelo xesha, i-viscosity iya kuhlahloka kwakhona.Ekubeni kuya kubakho i-polyethylene kwifilimu eyoluliweyo, sinokuhlengahlengisa inani le-polyethylene kwi-adhesive layer ukufezekisa i-viscosity oyifunayo.

Ekubeni i-molecular weight distribution yefilimu eyoluliweyo incinci kwaye uluhlu lokucubungula luncinci, ngokuqhelekileyo kuphela i-5% ye-polyethylene inokudityaniswa ukunciphisa i-viscosity enyibilikayo, ukwenzela ukuba i-flatness yefilimu eyoluliweyo nayo iya kuphuculwa.Yandisa ukuthambeka kwefilimu.
