Ngokuthuthuka komphakathi, abantu banamathela ngokubaluleka kwezempilo. Ukuphepha kokudla kuyinto esemqoka ethinta impilo yabantu ebilokhu ithathwa njengento enkulu ngabakhiqizi bokudla bakwamanye amazwe kanye nokuqapha kokuqondisa. Ukupakisha kokudla, ikakhulukazi, okokupakisha okuxhumana ngqo nokudla, kuhlobene ngqo nempilo yokudla, phambili empilweni yomzimba yomuntu. yingakho kunesidingo esiqine kakhulu ekupakisheni ukudla emazweni angaphandle ngokuya ngezindawo zobuchwepheshe nokuphepha kwezempilo .eminyakeni yamuva nje, iChina iphinde yaqinisa isidingo sokuphepha kwezempilo kwinqubo yokukhiqizwa kokudla. ngokumelene nalesi sizinda, kubaluleke kakhulu ukusebenzisa izinto zokupakisha zokudla ngokuphepha kwezempilo kokudla. njenge-materia enkulu yokupakisha, ifilimu ye-BOPET inokufaneleka okulandelayo:
PropertiesIzakhiwo ezinhle zomshini, izikhathi ezingama-3-5 zithinta amandla amanye amafilimu, abekezeleleka ekugoqeni.
Ukukhuthazela okuhle ngamafutha, amafutha, i-olefine acid kanye nama-solvents amaningi.
EnduranceUkukhuthazela okuhle okushisa okushisayo. iyasebenziseka esikhathini eside ngo-120 ℃, ngamagama amafushane, iyasebenziseka ngo-150 ℃, kwehle kuye kokungu-70 ℃, kube nomphumela omncane kakhulu kuzakhiwo zemishini.
GasUkungena kwegesi nomusi omncane, izakhiwo ezinhle zokuvimbela amanzi, uwoyela nephunga kuthuthukisa impilo yeshalofu.
Ifilimu ecacile ephezulu, ukumuncwa kwe-UV, ifilimu ephezulu ecwebezelayo.
Poisonno poison, no smell, good heath safety property, used in food packaging directly.
Abathengi banamathisela ukubaluleka okubaluleke kakhulu emfunweni yezempilo yokupakisha ukudla, i-esp. empilweni yeshalofu, ukuqabuleka kanye nezindawo ezilwa namagciwane. ngakho-ke ukufunwa kokusebenza okuhle kwefilimu ye-PET kuyanda .lokhu kuthuthukisa ukupakisha kokudla izinga.eminyakeni yamuva lapho kukhethwa izinto zokupakisha, kwagcizelelwa kakhulu izakhiwo zento, lokhu kusheshise ukuthuthukiswa kwefilimu ye-PET.
Ukutholakala kwe-oksijeni kuyinto ebalulekile ekukhetheni izinto zokupakisha zokudla, esikhwameni sokudla esivaliwe kahle, impilo yeshalofu yokudla ifinyelela ekungeneni komoya-mpilo, ikakhulukazi ukupakishwa kwe-vacuum kanye ne-anti oxygen packing material.I-BOPET inempahla enhle kakhulu yokuvimbela igesi, ngaphansi kwamazinga okushisa ekamelweni, impilo eshalofini yokudla okugcwele kweBopet iphindwe kabili iBopp. Ngaphandle kwalokho, i-Alu.plated Bopet Film inokusebenza okungcono ngokuya nge-oxygen nobufakazi obumanzi kunefilimu ye-Bopp. ukungena okumanzi kwe-Alu. ifilimu le-Bopet elihlanganisiwe lizokwehlela ku-0.3 ~ 0.6 lisuka ku-40 kuya ku-45. I-Versus Bopp, i-0.8 ~ 1.2 yehle isuke ku-5 ~ 7. (g / mm2.24h.40 ℃ ne-Alu. ubukhulu 60 ~ 70mm)
Ukusetshenziswa okubanzi kwefilimu leBopet ekupakisheni kuthuthukisa amandla, ama-reduecs apakisha okokusebenza ngesisindo ngasinye seyunithi nokungcola.ngakolunye uhlangothi, kukhulisa nobubanzi bezinga lokushisa, isb kusuka ekupakisheni okuhle okufriziwe kuya ekudleni okuphekiwe okuphezulu. term use in 120 ℃), it could be used for microwave oven. ngejubane elisheshayo lempilo yanamuhla, ukudla okune-microwave kuzojabulela ukuthandwa kakhulu phakathi kwabantu.
Ifilimu le-Bopet liyinto engcono kakhulu yefilimu ye-silican dioxide vacuum plating.silicon dioxide yenziwa ngokusebenzisa ifilimu yengilazi kwifilimu ye-BOPET, okungukuthi impahla yesithiyo idalwa ungqimba lwengilazi. ngakho-ke ukuze ugcine impahla eyisithiyo ngesikhathi senqubo yokufaka futhi usisebenzise kamuva, ungqimba lwengilazi kufanele luvikelwe ekulimaleni. ukusetshenziswa nokuthuthukiswa kwesithiyo esiphakeme seBOPET- ifilimu -vacuum -deposite -silica -oxide -material iphinde yagqugquzela ukupakisha kokudla kokungena endaweni yokukhanya okuphezulu, okusebenziseka kalula, okokusebenza kwemvelo .the vacuum deposit silica dioxide bopet film ibizwa nangokuthi ingilazi elithambile, linomsebenzi ofanayo namabhodlela engilazi ekugcineni ukunambitheka futhi ngeke lenze noma yiliphi iphunga ngemuva kokulondolozwa isikhathi eside noma ukwelashwa kwesikhashana futhi lijabulela impahla ye-Al emsebenzini wokuvimbela. ifilimu ifaka ukusobala okufanayo ngemuva kwesilayida deposit.so ukudla kungabonakala ngokusobala kusuka ekupakisheni okwenza isifiso sabathengi.
Azikho ezinye izithasiselo eziphilayo ezifakiwe ekukhiqizweni kwefilimu kwe-BOPET, futhi futhi kuyizinto ezisetshenzisiwe ezenziwe kabusha eziyenza ibe yimpahla yokupakisha enempilo, enobungani bemvelo.
