Ukuqhathanisa Izinhlobo Ezinhlanu Zamafilimu Kagwayi Wentuthu
1) PVC shwabanisa ifilimu
I-high desity, Ngenxa yokungasebenzi kahle kwe-optical, ukusebenza okunganele kokuvalwa kokushisa ukuze kuhlangatshezwane nezidingo zemishini yokushaja enesivinini esikhulu, kanye nemvelo engenabungane, imboni kagwayi yashiywa ngaphandle kokukhuthazwa okuphelele;
2) ifilimu ye-cellophane
I-cellulose evuselelwe, eyaziwa nangokuthi i-cellophane, ibonakala ngokusobala okuphezulu, ukucwebezela okuhle, ukuqina okuphezulu, ukuphrinta okuhle, futhi asikho isidingo sanoma yikuphi ukwelashwa ngaphambi kokuphrinta; Inezici zokulwa ne-static futhi akulula ukumunca uthuli. Kodwa i-cellulite ibaluleke kakhulu ( ρ≈ 1.31 g/cm3), nge-hydrophilicity kanye nokumelana nomswakama ompofu, ifilimu ijwayele ukuguquguquka ngenxa yokushisa nomswakama, futhi ayikwazi ukuvalwa ngokuqondile ukushisa. Ingapakishwa ngesandla kuphela futhi ayikwazi ukuzivumelanisa nemishini yokupakisha ugwayi wesivinini esikhulu. Ngaphezu kwalokho, ukusetshenziswa kwe-cellophane ekufakweni kukagwayi kunentengo ephezulu yeyunithi, eyashintsha kancane kancane;
3) I-Polyvinylidene chloride (PVDC)
Ifilimu kagwayi emboziwe inokusebenza okuhle kakhulu kokuvalwa kwezinga lokushisa eliphansi (izinga lokushisa lokuvalwa kokushisa lingu-107 ℃~140 ℃), futhi i-coefficient yokungqubuzana phakathi nenqubo yokupakisha ingaphansi kuka-0.3, okubonisa ukusebenza okuhle kwe-anti-static.
4) Ifilimu yentuthu ye-BOPP
Inezici ezingenakuqhathaniswa ezifana ne-haze ephansi, isicwebezelisi esiphezulu, ububanzi bokuvalwa kokushisa okubanzi, amandla okuvalwa kokushisa okuphezulu, ikhono elihle kakhulu lokuvimbela umhwamuko wamanzi, ugqinsi olufanayo, ububanzi bokulawula ukushwabana, ukuqina okuphezulu, nobungane bemvelo, kancane kancane iba into esemqoka yokupakisha ifilimu. ngogwayi.
5) Ifilimu ye-BOPLA nefilimu ye-PLA
I-BOPLA imele i-Polylactic Acid. Yenziwe ngezinsiza ezivuselelekayo ezifana nesitashi sombila noma umoba, i-polymer yemvelo eklanyelwe ukufaka esikhundleni samapulasitiki asekelwe ku-petroleum asetshenziswa kakhulu njenge-PET (i-polyethene terephthalate). Embonini yokupakisha, i-PLA ivame ukusetshenziselwa izikhwama zepulasitiki neziqukathi zokudla.
Ukwamukela ubuchwepheshe bokupakisha obuphambili nezindlela
Ukuze kunwetshwe impilo yeshalofu yokudla, kuthuthukiswe ubuchwepheshe obusha bokupakisha ngokuqhubekayo, njengokupakisha okusebenzayo, ukupakishwa kwesikhunta, ukupakisha okungamelana nomswakama, ukupakishwa kwe-anti-fog, ukupakisha okulwa ne-static, ukupakisha okuphefumulayo okukhethiwe, ukupakisha okuvikela ukushelela, ibhafa. ukupakisha, njll. Lobu buchwepheshe obusha busetshenziswe kabanzi emazweni athuthukile, kodwa abusetshenziswa kakhulu eShayina, futhi ezinye izindlela azikabhalwa lutho. Ukusetshenziswa kwalobu buchwepheshe obuphambili kungathuthukisa kakhulu umsebenzi wokuvikela wokupakisha.
Khetha imishini yokupakisha nezinto zokusebenza ezihambisana nobuchwepheshe bokucubungula ukudla
Ukuze kuhlangatshezwane nezidingo zobuchwepheshe bokucubungula ukudla, kuye kwasungulwa imishini emisha yokupakisha, efana nemishini yokupakisha i-vacuum, imishini yokufaka i-vacuum inflatable, imishini yokufaka i-heat shrink, imishini yokupakisha ama-blister, imishini yokupakisha efakwe emzimbeni, imishini yokwenza amashidi, imishini yokugcwalisa uketshezi. , ukwakha / ukugcwalisa / ukuvala imishini yokupakisha, ukupakisha oyinyumba amasethi aphelele emishini, njll. Ukukhetha noma ukuklama imishini yokupakisha ehambisana nobuchwepheshe bokucubungula ukudla kanye namandla okukhiqiza ngokusekelwe ezintweni ezikhethiwe zokupakisha kanye nezindlela zenqubo yokupakisha kuyisiqinisekiso sokupakishwa okuphumelelayo.
Ukuqwashisa ngomkhiqizo ekwakhiweni komhlobiso wokupakisha kanye nomklamo wokupakisha
Idizayini yokupakisha nokuhlobisa kufanele ihambisane nezintandokazi nemikhuba yabathengi kanye nabathengi ezweni elithumelayo. Kungcono ukuxhumanisa umklamo wephethini nengaphakathi. Uphawu lokuhweba kufanele lubekwe ngokugqamile futhi umbhalo kufanele uhambisane nezidingo zokudla. Incazelo yomkhiqizo kufanele ibe yiqiniso. Uphawu lokuhweba kufanele luhehe, luqondeke kalula, lusakazwe kalula, futhi lungadlala indima yokukhangisa esabalele. Umklamo wokupakisha wemikhiqizo yomkhiqizo odumile kufanele ube nokuqwashisa ngomkhiqizo. Okunye ukupakishwa kwemikhiqizo kulula ukukushintsha, okuthinta ukuthengiswa. Isibonelo, uviniga wase-China wase-Laoliutiao unegama elihle e-Japan naseNingizimu-mpumalanga ye-Asia, kodwa umthamo wokuthengisa wehla kakhulu ngemva kokushintsha ukupakisha, ngoba abathengi banokungabaza mayelana nokupakishwa okusha. Ngakho-ke, umkhiqizo kufanele uhlanganiswe ngokwesayensi futhi awukwazi ukushintshwa kalula.
I-1, Izidingo okufanele zihlangatshezwe ngezikhwama zokupakisha zebanga lokudla
Ukupakishwa kwebanga lokudla kufanele kuhlangabezane nezidingo zokuvikela zazo zonke izici zokudla
Izidingo zokupakishwa kokudla zingavimba umhwamuko wamanzi, amagesi, amafutha, nezinyibilikisi zemvelo;
2. Ngokwezidingo ezikhethekile zokukhiqiza kwangempela, engeza imisebenzi efana nokuvimbela ukugqwala, ukuvimbela ukugqwala, nokuvimbela imisebe kagesi;
3. Qinisekisa ukuphepha kokudla kanye nokungangcoli ngenkathi unweba isikhathi seshalofu lokudla.
Izinto eziyinhloko nezisizayo ezisetshenziswa ekufakweni kwebanga lokudla akumele ziqukathe izinto ezingase zidale ukulimala emzimbeni womuntu, noma okuqukethwe kufanele kube phakathi kwebanga elivumelekile lamazinga kazwelonke.
Ngenxa yesimo esiyingqayizivele sokupakishwa kwepulasitiki yebanga lokudla, ngokulandela ngokuqinile izindinganiso zokukhiqiza imikhiqizo ingavunywa futhi ifakwe emakethe.
Zonke izikhwama zokupakisha zangaphakathi ezihlangana nokudla zihambisana ngokuqinile nenqubo yokukhiqiza izikhwama zokupakisha zebanga lokudla, ezingagcini nje ngokuqinisekisa ukuphepha nokuhlanzeka, kodwa futhi ziqinisekisa ukunambitheka kwangempela okumnandi.
Esikhundleni sezikhwama zokupakisha zebanga lokudla, umehluko omkhulu ekubunjweni kwezinto ezibonakalayo usekusetshenzisweni kwezithasiselo. Uma ama-ejenti okuvula engezwa ezintweni, angeke asetshenziselwe ukupakisha ukudla.
2, Indlela yokuhlukanisa phakathi kwebanga lokudla kanye nezikhwama zokupakisha ezingezona ezokudla?
Lapho uthola isikhwama sokupakisha, bheka kuqala. Impahla entsha sha ayinalo iphunga, umuzwa omuhle, ukuthungwa okufanayo, nemibala egqamile. Yilezo ezihlangabezana nezindinganiso kuphela okuyibanga lokudla kanye nezikhwama ezihambisana nemvelo eziphephile nezihlanzekile.
3, Ukwahlukaniswa kwezikhwama zokupakisha ukudla
Ngokusho kobubanzi bokusebenza kwayo, ingahlukaniswa ibe:
Izikhwama ezijwayelekile zokupakisha ukudla, izikhwama zokupakisha ukudla ezifuthayo, izikhwama zokupakisha ukudla ezivuthezekayo, izikhwama zokupakisha ukudla okubilisiwe, izikhwama ezipakishwayo zokudla okushubile, nezikhwama ezisebenzayo zokupakisha.
Kukhona futhi izinhlobo eziningi zezinto: izikhwama zepulasitiki, izikhwama ze-aluminium foil, nezikhwama eziyinhlanganisela zivamile.
Izikhwama ze-vacuum zisetshenziselwa ukukhipha nokuvala wonke umoya ngaphakathi kwephakheji, ukugcina isimo sokucindezeleka okukhulu ngaphakathi kwesikhwama. Ukushoda komoya kufana nomthelela omncane we-oksijeni, okwenza kungenzeki ukuthi ama-microorganisms aphile, ukuze afeze umgomo wokudla okusha futhi kungabikho ukwenzeka kwezifo nokubola.
Izikhwama ze-aluminium foil zokudla zenziwe nge-aluminium nezinye izinto ezivimbelayo eziphezulu ngokusebenzisa inhlanganisela eyomile ngokusekelwe ezintweni eziyingqayizivele ze-aluminium. Izikhwama ze-Aluminium foil zinokumelana nomswakama okuhle kakhulu, umgoqo, ukumelana nokukhanya, ukumelana nokuqina, nokubukeka okuhle.
Izikhwama eziyinhlanganisela yebanga lokudla ziyakwazi ukumelana nomswakama, ukumelana nokubanda, nokushisa okuphansi kwezinga lokushisa elivalwe ngamandla aqinile.
