I-silicone ifakweIfilimu yokukhutshwa kwePolyesteryenzelwe ukusetyenziswa njengelinen yokukhulula kwisicelo sokuncamathelisa esibuthathaka.Idla ngokubizwa ngokuba yifilimu ye-peel, ifilimu yokukhulula okanye i-liner yokukhulula, esebenzisa ifilimu yepolyester njengefilimu ephetheyo kunye necala elinye okanye icala eliphindwe kabini eliqatywe nge-oyile ye-silicone ukunciphisa amandla okufunxa kwicala lokuncamathela kunye nokuphumeza ukukhululwa kwiiteyiphu zokuncamathelisa.
Ifilimu yokukhululwa kwe-polyester inokwahlulwa ngamandla ahlukeneyo okukhululwa: ifilimu yokukhululwa kokukhanya, ifilimu yokukhulula amandla aphakathi kunye nefilimu yokukhupha amandla.Ngaphandle koko, sinokubonelela ngobubanzi obuhlukeneyo ukusuka kwi-12um, 19um, 25um, 38um, 50um, 75um, 100um, 125um, njl ukuhlangabezana nesicelo esahlukileyo.
