I-Composite Flexible Packaging Materials Development Trend e-China

Thuthukisa ifilimu yokupakisha ethambile eyinhlanganisela enobungani bemvelo.Njengamanje, umhlaba ubhekwa njengonobungani nemveloI-PETimpahla, futhi ingaphinda igaywe futhi isetshenziswe kabusha.Ngenxa yokuthuthukiswa kwezinga lempilo yabantu, impilo yama-racks okudla kwasezitolo izokhula, futhi inani le-BOPET lizoqhubeka nokukhula, futhi lizosiza ekugayweni kabusha nokusetshenziswa.

Kuyavumelana nezimoI-membrane yokupakisha yepulasitiki ithuthuka ngendlela yokusebenza okuzinikele.Isibonelo, izinto ezimelana kakhulu nezinongo seziphenduka into ethambile yokupakisha ukuze kuthuthukiswe izinongo ezishisayo.Okuvame ukusetshenziswa izinto ze-PVDC, izinto zokupakisha zenayiloni, izinto ze-EVOH, ifilimu yokuhlanganisa i-inorganic oxide, njll. Indima yokuphila kweshalofu.Izinto eziyinhlanganisela ezimelana kakhulu zizoqhubeka nokwandisa umthamo wemakethe.Esikhathini esizayo, ifilimu yokumelana okuphezulu, enokucubungula okulula, ukumelana okuqinile nomoya-mpilo, ukusebenza komhwamuko onamandla wamanzi, kanye nezinzuzo zokuqopha impilo yeshalofu, iyona ehamba phambili yokupakishwa okuthambile kokudla kwasesitolo esikhathini esizayo.Ubuchwepheshe obuhlanganisiwe bezendlalelo eziningi, obuxubene, bokuhlanganisa ndawonye, ​​kanye nobuchwepheshe be-steam nakho kuthuthuke ngokushesha kakhulu embonini yokupakisha ethambile.

Kuyavumelana nezimoizinto zokupakisha zikhula zibe mncane.Ifilimu elizacile lefilimu lisho ukushuba kwezinto ezincishisiwe futhi izinkomba zokusebenza zamaphakeji ezihlukahlukene zisengakwazi ukuhlangabezana ngokugcwele nezimfuneko zephakeji.Kunezindlela ezintathu eziyinhloko ezingafinyelela lokhu: Okokuqala, thuthukisa izinto ezintsha, sebenzisa i-PEN njengezinto zokusetshenziswa, amandla e-PET akhiqizwa yi-PET anganyuswa izikhathi ezingu-3.5, futhi ubukhulu befilimu bungancipha ngo-1/3 I-BOPET, engahlangabezana nezidingo zefilimu ye-BOPET.Okwesibili ukwenza ifilimu yokupakisha ethambile enento eyinhlanganiselaNi-ano inorganic kanye ne-polymer.I-Nano inorganic kanye ne-high-polymers composite materials ingathuthukisa amandla kanye nokuqina kwefilimu ngesikhathi esisodwa, edlala indima ebalulekile ekubunjweni okuncane kokupakishwa kwepulasitiki ethambile.Uma kuqhathaniswa nefilimu encane eyenziwe nge-polymer ehlanzekile, amandla nokuqina kwefilimu efilimu kufilimu kukhuphuka ngo-50%.Okwesithathu ukusebenzisa izinto zokupakisha ezinezingqimba eziningi ukuze kuthuthukiswe ukusebenza okuphelele kwezinto zokupakisha ezithambile, ukunciphisa inani lepulasitiki ekupakishweni okuthambile, ukunciphisa ukungcoliswa kwemvelo nokusindisa izinsiza.
