Ikhava Yokupakisha Yokudla Nesiphuzo Ifilimu Ibhodlela Lebhodlela Lebhodlela Lomlomo Wepulasitiki Ukuvalwa Okulula Kwefilimu Yokuvala Izinyembezi Yomshini Ozenzakalelayo Wokucwenga

I-Parafilim iyinhlanganisela esebenza ngokuvaleka, umphumela wokulwa nomgunyathi, evimbela ukuguquguquka nokungcoliswa kokuqukethwe komkhiqizo, kanye nemvula engenaphunga.
Ukuze kuxazululwe inkinga yokuvalwa kokushisa, ngokuguqulwa kwe-PET resin kanye nokusetshenziswa kwe-A/B/C yesakhiwo esinezingqimba ezintathu kuyafa, ifilimu ye-PET enezingqimba ezintathu ehlanganiswe ngokuhlanganyela ekushiseni yakhiwe. Le filimu ye-PET ye-heat-sealing ngenxa yokuthi kunesendlalelo esivala ukushisa ohlangothini olulodwa, singavalwa ngokuqondile ngokushisa, okuyinto elula kakhulu ukuyisebenzisa. Ifilimu ye-PET evaleka ukushisa ingasetshenziswa kabanzi emikhakheni yokupakisha namafilimu okuvikela amakhadi ezimpahla ezahlukahlukene.
I-PET ejwayelekile iyi-polymer ecwebezelayo. Ngemuva kokuthi ifilimu ye-PET inwetshiwe futhi iqondiswe, izokhiqiza izinga elikhulu le-crystallization. Uma ivalwe ngokushisa, izoshwabana futhi yonakale, ngakho ifilimu evamile ye-PET ayinazo izinto zokuvala ukushisa. Lapho ifilimu ye-PET isetshenziswa njengokupakishwa kwempahla, ukuze kuxazululwe inkinga yokuvalwa kokushisa, indlela yokuhlanganisa ifilimu ye-BOPET ngefilimu ye-PE noma ifilimu ye-CPP ivame ukwamukelwa, okukhawulela ukusetshenziswa kwefilimu ye-BOPET ngezinga elithile.
Lo mkhiqizo usetshenziswa kabanzi ku-: ifilimu yokupakisha yezimonyo, ifilimu yokuvalwa kwezidingo zansuku zonke, ifilimu yokufaka ukudla emaphaketheni, ifilimu yokufaka uphawu lokufaka imithi kanye nefilimu yokufaka uphawu yamakhemikhali nezinye izimboni.
Ngaphezu kwalokho, inezindawo ezilwa nokukhwabanisa kanye nokweba, futhi ingaphrinta izikhangiso zenkampani efilimini yokuvala ukuze kuzuzwe imiphumela yokukhangisa.
Ilungele iziqukathi ezingezona ezensimbi ezifana ne-PET, i-PVC, i-PP, i-PE, i-PS, NJENGOBA izinhlobo ezahlukene zezinkomishi zokujova, amabhodlela omjovo, amabhokisi amabhamuza, amabhodlela abunjiwe, izinkomishi ezibunjwe ngokushaywa, nezingxenye ezibunjiwe.
