Izithwethwe zokugcina zezindilinga zokugcina ziziphi?

Izibalo zokugcina zezindilinga zokugcina kubizo lwezifundo zokuphatha izinkomo

Izifilm zokugcina zihlanganiswa ngemikroni, futhi isilinganiso sesikhundla esisodwa kusukela ku-12 kuze ku-200 mikroni sibonakala kakhulu kuzifilm zokugcina zezinkulungwane. Imikroni yisilinganiso sesikhundla sokubasekwa kwezinkulungwane zokugcina ezinamandla. Kuzifilm zokugcina zezinkulungwane, umbono omuhle kakhulu uyoba ukulandela imithetho yezinkulungwane zokuxhumana ngezinkulungwane ephansi kwesiphambano sezinsizakwazi. I-FDA 21CFR 177.1520 yisilinganiso esisodwa kakhulu kusukela kumlando wokuthengisa, futhi isebenza kakhulu ekuxhumana ngqo nezinkulungwane. Ngaleso mbono, ubude nobuchwepheshe bezifilm zokugcina zezinkulungwane azikwazi ukuba yisidingo sokusebenza. Abakhalendeli bethu bezinkulungwane zokugcina bazisebenza ngempilo emazwe amashumi amathathu namabili futhi amagunya, ngokushiyela izinsizakwazi zethu zeminyaka emashumi amabili futhi ukulandela imithetho.

Izinketho Zobude Kuzinkulungwane Zokugcina

Njengoba kunikezwe ukukhiqizwa ngobuningi ngama-kilogram angu-8 000 wefilimu ye-roll ekhiqizwa nsuku zonke, ubukhulu obukhulu obusetshenziselwa ukupakisha ukudla okujwayelekile buphakathi kwamabanga amabili. Lapho amafilimu e-roll esebenza kuma-microns angu-12 kuya kwangu-30, asetshenziselwa ukupakisha ukudla okulula okudliwayo okudliwayo okudliwayo okufana nama-chips e-tortilla, kanye nezithelo ezomisiwe kanye nezingxube zamantongomane. Ukuphrinta ngokwezifiso kungenziwa kalula kumafilimu alula, futhi kunikeza umenzi wesiphuzo indlela yokuhlangabezana nezidingo zokubeka uphawu, kuyilapho ifilimu inikeza ukuvikelwa okuyisisekelo othulini nomswakama omncane. Amafilimu angamamayikroni angu-30 kuya kwangu-60 ayathandwa ekupakisheni ikhofi, itiye nezinongo zokusanhlamvu. Lolu hlu lobukhulu lunikeza umswakama ongcono nokuqina komoya ukuze kugcinwe iphunga lekhofi netiye, kanye nokuhluma okusanhlamvu okomiswe isikhathi eside. Lezi zinhlobo ezijwayelekile zokubopha kulula ukuzenza, okusiza abakhiqizi bokupakisha ukudla ukuba bonge izinto zokusetshenziswa nokushintsha isikhunta.

Izidingo Zomkhiqizo I-Heavy Duty Roll Film

Izidingo zomkhiqizo zokupakisha ukudla okukhethekile zinikeza ukuvikelwa okungcono kakhulu/izidingo zinikeza ukuvikelwa okungcono kakhulu ngendlela yamafilimu amakhulu. Ukudla kwezilwane ezifuywayo nokupakisha ukudla okusetshenziselwa amasosi namafutha kudinga amafilimu agingqikayo anobukhulu obungama-micron angu-60 kuya kwangu-120. Izikhwama ezinesisekelo esiyisicaba ezisetshenziswa ekupakisheni ukudla kwezilwane ezifuywayo zinikeza isivikelo esihlala isikhathi eside sezikhwama ngesikhathi sokuthutha kanye nokugcinwa. Futhi, ekupakisheni usoso namafutha, lokhu kukhulu kuyaziswa ngenxa yokusebenza kwayo okuvikela ukuvuza, ikakhulukazi ezikhwameni ze-spout ezivumela ukuchithwa okulula. Ukuze uthole ubisi oluyimpuphu neziphuzo ezishisayo, amafilimu amakhulu kakhulu okudliwayo (ama-microns angu-120 kuya kwangu-200) anikeza amafilimu amahle kakhulu. Lobu busindo buwusizo kakhulu ekulondolozeni ukudla okunomsoco kobisi oluyimpuphu futhi buvikela isikhwama ekuqhekekeni nasekucwileni. Ngaphezu kwalokho, lezi zindilinga ezisindayo, ezinobukhulu obuhlukahlukene, zinikeza isivikelo esihle ukuze kuthuthukiswe futhi kwandiswe isikhathi sokugcina imikhiqizo. Ngaphezu kwalokho, amafilimu esindayo alulaza imfucuza yemikhiqizo edlulayo kulo lonke uchungechunge lokuphakelayo.

Ukukhetha Ububanzi Ngokwesifundo Sesifunda

Ubukhulu be-film yomkhumbulo kubandakanya ngqo kwezinkundla zayo zokulondoloza. Kepha, akuyiyo kuphela ukuzilonda; kufanele kubhekwe nokwakha kwematerial ne-technology yokugcina njengoba kubhekwe nge-bukhulu ukuze kufikeke ubukhulu obuhle bokulondoloza. Kuma-film osebenzisa emoyeni yezinkundla zokulondoloza izinkomo, izinkundla ezintathu zokulondoloza ziyizinkundla zokulondoloza umshumayeli, ukulondoloza kwe-air, nokulondoloza kwe-oxygen. Umunye walezi zinkundla zokulondoloza kune-bukhulu obumnini. Isibonelo, i-film eyolondoloza umshumayeli yezinkomo ezingavaliwe kufanele ibe yinkulu kune-20 microns; kuma-film oyolondoloza kwe-oxygen yezinkomo ezingavaliwe ngokuphuma kwemithambo, kufanele ibe yinkulu kune-50 microns. Abasunguli be-flexible packaging bazi ukuthi ukuthinteka kwebhili yefilm ngaphandle kokuzilonda kuyizindlela zokuthinteka okuningi kakhulu. Ngaphakathi, kuyizindlela zokuhlukanisa ukugcina obuhle nokubukhulu obuhle okuyizindlela ezinconywa ukuzilonda izinkundla zokulondoloza zefilm. Le ndlela enconywa iyisivumelwano esiphakade esebenzisa i-flexible packaging industry futhi yisibasiso sokufika kubukhulu obuhle bekholi nokusebenza.

Ukubalansisa Ububanzi Nokusebenza Okuhle Kunye Nezindlela Zokuthenga Okuhle

Ukukhetha ububanzi obuhle bocingo lwesikhumba kufuna ukuchaza okuhle kwezindlela zokusebenza nokuthenga kwanoma yiziphi izindlela, lokhu sisifunda emva kokusebenza kubabili abaningi kunezizwe eziyisikumi nambili. Ucingo olububi kakhulu lungezela umsebenzi wokwenza amabhagi nezinkampani zokufaka, lizidelela ukusebenza kwemithambo yokuqala, lizidelela ukusebenza kwemithambo yokuqala, futhi lizidelela ukugcina kwezincwadi zemithambo; ngakolunye uhlangothi, ucingo oluncane kakhulu lungezela ukuthi kuzidelele kakhulu kumsebenzi wokwenza futhi ukungathembeki kakhulu kwezinto ezihlakazwa. Izinkampani zokusebenza kunye nezinto ezihlakazwa ziyachaza 'isikhumba esihle' sokububanzi kwesikhumba. Kukusebenzisa isikhumba sokuhlakazwa, ububanzi obuhle lungezela ukuthinteka kwemateriali ngama-30% okuyisibonelo esikhulu sokuthenga okuhle kubabili abasebenza. Ukufumana lokhu ubalansi kububanzi bocingo akuyiyo kuphela isiphakade sokuthinta izinto, kodwa yilokho okuphambili okufanele kusukela ekuthinteni kwezindawo zokuthengiswa futhi ukuthengiswa kwezinto.

Amasiko Okusha Kwebubanzi Bocingo Lwesikhumba Nokuthinta Kwemisebenzi Yokuhlakazwa Yezinto

Ukuphatha ngokuzimisa kuyisibonelo esitsha sokuhamba kwisayensi yokubhala amaphakethi okufunyanwa ngokuvamile, futhi ukudesigna ubude beshilikhili yomkhumbulo wawo akukho isibonelo sokugcina. Ukuncamisa kuyisibonelo esitsha sokudesigna. Isayensi iyahamba awaye kumakhubalo amathuluzi amathuluzi ayisisekelo futhi iyabhekana nesikhubalo esincamile ngokuphelele nesikhubalo esinamandla okubhala. Lezi zikhubalo zikusinda ukusebenzisa izinto ezinkulu zokubhala ngokuphelele kodwa zinakha ukuphatha okufanayo nokuphatha kwezikhubalo zokubhala zokusebenzisa ngokuvamile, noma kungenzeka kubheke kakhulu. Umzekelo, isikhubalo somkhumbulo wesikhombisa 30-micron nesikhubalo sesikhombisa sika-nano sinakha ukuphatha okufanayo kwe-oxygen njengesikhubalo somkhumbulo wesikhombisa 60-micron esingasikhombisa. Ukusebenzisa isikhubalo somkhumbulo esincamile sivumela izinqumo zokubhala ngokuzimisa zabezifundisa abasebenzi bokubhala futhi zivumela izinqumo zokuphatha ngokuzimisa zezwe zonke. Lokhu kusinda ubuchwepheshe bezinhloso zokubhala futhi kusinda ubuchwepheshe be-carbon bekuphatha. Kungakumbi ukuthi abasupplyer basebhalo besifunda ngokuvamile bafuna ukubeka iziqondiso zabo nezimali zabo kuzinhloso zokubhala zokubhala ngokuvamile zokubhala izinkomo.
