Ifilimu ye-BOPA ifilimu enwebekayo ye-biaxial, engatholwa ngokufutha kanye nokwelula kwe-biaxial kanyekanye. Ifilimu inganwetshwa kancane kancane kusetshenziswa indlela ye-T-mold extrusion, noma kanyekanye yelulwe nge-biaxially kusetshenziswa indlela yokubumba i-blow. Izici zefilimu ye-BOPA zimi kanje:
(1) Ukuqina okuhle kakhulu. Amandla aqinile, amandla okudabula, amandla omthelela, namandla okuphuka kwefilimu ye-BOPA konke kuphakathi kokuhamba phambili phakathi kwezinto zepulasitiki.
(2) Ukuguquguquka okuvelele, ukumelana nembobo yenaliti, nobunzima bokubhoboza okuqukethwe kuyisici esikhulu se-BOPA, esinokuguquguquka okuhle nomuzwa omuhle wokupakisha.
(3) Izakhiwo ezinhle zokuvimbela, ukugcinwa kwephunga elimnandi, ukumelana okuhle kakhulu namakhemikhali ngaphandle kwama-asidi aqinile, ikakhulukazi ukumelana nowoyela.
(4) Izinga lokushisa libanzi, linendawo yokuncibilika engu-225 ℃, futhi lingasetshenziswa isikhathi eside phakathi kuka -60 ~ 130 ℃. Izakhiwo zemishini ze-BOPA zihlala zizinzile emazingeni okushisa aphansi naphezulu.
(5) Ukusebenza kwefilimu ye-BOPA kuthinteke kakhulu umswakama, ikakhulukazi mayelana nokuzinza kwe-dimensional kanye nezakhiwo zokuvinjelwa. Ngemuva kokuswakama, ifilimu ye-BOPA ivamise ukunwebeka ngokusemaceleni, ngaphandle kokushwabana. Ukufinyezwa kwe-longitudinal, okunobude obukhulu obungu-1%.
3. Ifilimu ye-CPP
Ifilimu ye-CPP, eyaziwa nangokuthi ifilimu ye-polypropylene eyi-cast, ifilimu ye-polypropylene engasuki, engaqondile. Ihlukaniswe yaba i-homopolymer CPP kanye ne-copolymer CPP ngokuya ngezinto zokusetshenziswa. Izinto ezingavuthiwe eziyinhloko zokupheka ifilimu ye-CPP yebanga i-block copolymer ekwazi ukumelana ne-polypropylene. Izidingo zokusebenza yilezi: izinga lokushisa lephoyinti elithambile le-Vicat kufanele libe phezulu kunezinga lokushisa lokupheka, ukumelana nomthelela kufanele kube ngcono, ukumelana okuphakathi kufanele kube ngcono, futhi iso lenhlanzi nephoyinti lekristalu kufanele kube kumbalwa ngangokunokwenzeka.
4. I-aluminium foil
I-aluminium foil iwukuphela kohlobo lwe-foil yensimbi ezintweni zokupakisha ezithambile, ezisetshenziselwa ukupakisha izinto ezinesikhathi eside sokufaka isicelo. I-aluminium foil iyinsimbi ekwazi ukumelana namanzi ngokungenakuqhathaniswa, ukumelana negesi, ukuvikela ukukhanya, kanye nezakhiwo zokugcina ukunambitheka uma kuqhathaniswa nanoma iyiphi enye impahla yokupakisha. Kuyimpahla yokupakisha engakwazi ukushintshwa ngokuphelele kuze kube yilolu suku.
5. I-Ceramic evaporation coating
I-Ceramic vapor coating iwuhlobo olusha lwefilimu yokupakisha, etholakala ngokuhwamulisa ama-oxide ensimbi ebusweni befilimu yepulasitiki noma ephepheni njenge-substrate emishinini yokuhlanza ephezulu. Izici ze-ceramic vapor coating ikakhulukazi zifaka:
