Iphepha Lokwenziwa Kwezimvilophu Zokukhiqiza Imininingwane

Chaza iphepha lokwakheka kwe-Kraft lama-envelope

Ukuthola ilungeloiphepha le-kraft lokukhiqiza imvilophuiqala ngokuqonda izakhi eziyisisekelo zale nto. Lenziwe ngokuyinhloko ngemicu ye-cellulose yokhuni ngenqubo yamakhemikhali e-kraft, leli phepha liqinile ngokwemvelo, liyasebenziseka kalula, futhi linobungani nemvelo.

Izinto zokwakha zenzelwe ngqo ukusingatha ubunzima bemigqa yokukhiqiza ezenzakalelayo ngenkathi kuvikelwa amadokhumenti, amakhathalogi, kanye nezimpahla ezilula ezithuthwayo. Ezindlini zokunyathelisa ze-B2B kanye nezinkampani zezokuthutha, ukucacisa isisekelo esifanele kuvimbela ukuminyana kwemishini okubizayo kanye nokuchithwa kwezinto.

Izidingo zokuguqula ukhiye

Abakhiqizi badinga iphepha eliziphatha ngendlela ebikezelwayoindawo yokukhiqizaImishini yokuguqula ama-envelope ivame ukusebenza ngesivinini esikhulu, icubungula noma yikuphi kusuka kuma-envelope angu-500 kuya ku-1,200 ngomzuzu. Kulezi sivinini, iphepha kumele linikeze ukugoqeka okuhle kakhulu ngaphandle kokuqhekeka emithungweni.

Ukuqina kungenye into ebalulekile; uma iphepha libuthakathaka kakhulu, lizovimba imishini egoqwayo, okubangela isikhathi esibizayo sokungasebenzi kanye namazinga aphezulu okukhubazeka. Ngaphezu kwalokho, indawo engaphezulu kumele yamukele izinamathiselo ezijwayelekile namafilimu okuvala amafasitela ngaphandle kokuphazamiseka, okuqinisekisa ukuthi ukusetshenziswa kwe-glue okusheshayo (okuvame ukubizwa ngokuthi ngaphansi kwemizuzwana engu-0.5) kudala isibopho esihlala njalo nesiphephile.

Imigomo yokucaciswa okuyinhloko

Ukuze bathenge izinto ezifanele, abathengi kufanele bakhulume ulimi lwemishini yokugaya iphepha. Amagremu ngemitha yesikwele (i-GSM) anquma isisindo nobukhulu, okuthonya ngqo kokubili ukuqina kanye nezindleko zokugcina zokuthumela.

Isiqondiso somshini (MD) kanye nesiqondiso esiphambene (CD) zichaza ukuhambisana kwemicu, okuthinta indlela iphepha elidabula futhi ligoqeke ngayo emigudwini yemvilophu. Okuqukethwe komswakama kudlala indima enkulu ekuguquleni impumelelo futhi. Izinga lomswakama elivame ukuhloswa phakathi kuka-5% no-7% livame ukudingeka, yize lokhu kuhlukahluka ngokwesimo sezulu sesigayo kanye nesifunda; izindawo ezinomswakama ophezulu, isibonelo, zingadinga izinhloso zomswakama ezilungisiwe ukuvimbela iphepha ukuthi lingagobi, linciphe, noma libe buthakathaka kakhulu ngesikhathi sokugcina nokucubungula izimpahla.

Qhathanisa Imininingwane Yephepha Le-Kraft

Uma uqhathanisaimiqulu emikhulu yephepha le-kraft, abathengi kumele balinganise izakhiwo zemishini ngokuqhathanisa nobuhle bokuqedwa.

Umeyili weposi onwebeka kakhulu udinga isethi yemininingwane ehluke ngokuphelele kune-imvilophu yefasitela yenkampani ejwayelekile, futhi ukucacisa lezi zakhiwo kuvimbela kokubili ukwehluleka komkhiqizo kanye nokusetshenziswa kwezimali okungadingekile.

I-GSM, amandla okuthamba, ukumelana nokudabuka, kanye nokugoqeka

Izitayela ezahlukene zemvilophu zidinga izigaba ezithile zesisindo kanye namaphrofayili amandla. Esikhundleni sokubheka nje izincazelo eziyisisekelo, abathengi kumele bahlole ukuthi lezi zilinganiso zisebenza kanjani kumkhiqizo wabo othize. Amandla okudonsa, alinganisa ukuthi iphepha lingacindezela kangakanani ngaphambi kokulisika, avame ukubizwa ngokuthi adinga ukuba ngaphezu kuka-5.0 kN/m ohlangothini lomshini ukuze kuthunyelwe iposi elithembekile, yize lokhu kuncike endinganisweni yokuhlola esetshenzisiwe.

Ukumelana nokudabuka kuqinisekisa ukuthi amakhona abukhali emibhalo ngeke ayibhoboze imvilophu ngesikhathi sokuhamba. Ukugoqeka kumele kuhambisane nomklamo wemvilophu, njengoba iphepha eliqinile elinesiqondiso esingesihle sokugoqeka lizoqhekeka kalula emaceleni emvilophu yokwandisa.

Izinketho zemvelo zephepha elinsundu, elimhlophe, nelimboziwe

Ukuphela okubonakalayo kwephepha nakho kuyasho ukusebenza kwalo kanye nomphumela walo endaweni ezungezile.I-kraft ensundu engeyona i-bleach yemveloivikela kakhulu imvelo futhi iyabola, okwenza ibe yintandokazi yemikhiqizo eqhubekayo efuna ukunciphisa umthelela wayo wekhabhoni.

I-kraft emhlophe idlula enkambisweni yoku-bleach—lapho i-chemistry ethile esetshenziswayo, njenge-Elemental Chlorine-Free (ECF) vs Totally Chlorine-Free (TCF), ibalulekile ezimangalweni zokusimama—ukuhlinzeka ngesizinda esicacile nesinomehluko omkhulu semiklamo yokuphromotha enemibala. Kodwa-ke, uku-bleach kunganciphisa amandla e-fiber cishe ngo-5% kuya ku-10%, okusho ukuthi abathengi bangadinga ukukhulisa i-GSM kancane ukuze ifane nokuqina kwemvilophu ensundu. Izinketho ezimboziwe nazo ziyatholakala, zengeza izithiyo ezingamelani nomswakama noma ama-poly-linings amaphakheji adinga ukuvikelwa okwengeziwe kwesimo sezulu, yize kubalulekile ukuqaphela ukuthi i-kraft embozwe nge-poly ivame ukungaphinde isetshenziswe emifudlaneni ejwayelekile.

Khetha Iphepha Elifanele Lokwakheka

Ukukhetha iphepha elifanele lobuciko kuncike ekuhloleni izinto ezimweni zangempela nokuvumelanisa leyo miphumela nenani lenkampani.

Iphepha eliqine kakhulu emhlabeni ngeke lisize uma lingakwazi ukubamba uyinki kahle, livala iphrinta ye-offset, noma libiza kakhulu ukuthunyelwa ngobuningi.

Izinyathelo zokuhlola ukuphrinta

Ngaphambi kokuzibophezela ku-oda elikhulu, abaguquli kufanele basebenzise uhlu lokuhlola olufanele. Amaqembu okuthenga kufanele aceleizitifiketi zokugayayokuhlaziya (i-COA), qinisekisa ukuhambisana kwe-caliper kulo lonke umqulu, bese uhlola ukuthi i-cockling isezingeni lomswakama eliqondiwe.

Okulandelayo, abaguquli kufanele benze izivivinyo zokuphrinta ze-flexo noma ze-offset. Ubuso bephepha budinga ukuba bushelelezi ngokwanele ukuze bubambe imininingwane yebhakhodi encane kodwa bube nokwakheka okwanele ukuze bumunce uyinki ngokushesha ngaphandle kokugcotshwa. Ama-Mills alinganisa lokhu esebenzisa isikali sobushelelezi se-Bendtsen; ukufundwa okungu-200 kuya ku-400 ml/min ngokuvamile kulungele ukuphrinta okujwayelekile kwemvilophu. Kuhlale kuyisinyathelo esihlakaniphile ukusebenzisa ibhetshi lokuhlola lezingcezu ezingu-5,000 ukuhlola ukunamathela kweyinki, ukucaca kwelogo, nokuthi izinamathiselo zinamathela kahle kangakanani eziphepheni zephepha ngaphansi kwezimo ezivamile zokomisa.

Ukufanisa iphepha nezidingo zebhizinisi

Ekugcineni, imininingwane kufanele ihambisane nezidingo zokusebenza zomsebenzisi wokugcina. Izikhungo zezimali ezithumela amadokhumenti abucayi zidinga ukufiphala okuphezulu (ngokuvamile okuchazwe ngaphezu kwama-95%) futhi zingadinga ne-tint yokuphepha eyenziwe ngokwezifiso ephrintiwe ngaphakathi. Ngenxa yokuthi ukufiphala kanye ne-tint yokuphepha kuyimininingwane ehlukile futhi akukho okukodwa okuqinisekisa ubumfihlo obuphelele, kuvame ukuhlanganiswa.

Izinkampani ze-e-commerce kanye nezinkampani zezokuthutha zibeka phambili ukuqina okulula ukuze kuncishiswe izindleko zokuthumela ngeyunithi ngayinye. Lapho bethenga lezi zinto, amaqembu okuthenga nawo kudingeka acabangele inani elincane le-oda (ama-MOQ).Ama-jumbo roll enziwe ngokwezifisongokuvamile kudinga i-MOQ yamathani angu-3 kuya kwangu-5. Ukuvumelanisa izici zobuchwepheshe nomthamo wokugcina, imigomo yokuthobela imithetho, kanye nemikhawulo yesabelomali kuqinisekisa ukusebenza kokukhiqiza okubushelelezi nokungabizi kakhulu.

Ukuze baqondise isinqumo sokugcina, abathengi bangahlanganisa izinhlobo zabo zemvilophu nezinqwaba zemininingwane ezinconyiwe:

● Ibhizinisi Elijwayelekile:I-70–90 GSM, i-MD tensile target ephakathi nendawo, isiphetho esibushelelezi, esifanele ukuphrinta kwe-offset okusheshayo.

Izinto Ezibalulekile Okufanele Uzicabangele

● Qondanisa i-GSM yephepha lokwakha nohlobo lwemvilophu, usebenzisa cishe i-GSM engu-70–90 kumamvilophu ebhizinisi ajwayelekile kanye ne-GSM engu-100–120 kumaposi amaningi ekhathalogi.
● Cacisa isiqondiso somshini kanye nesiqondiso esiphambene ngokucacile ngoba ukuhambisana kwefayibha kuthinta ngqo ikhwalithi yokugoqa, ukuziphatha kokudabuka, kanye namandla omthungo.
● Lawula okuqukethwe komswakama okuzungeze uhla olunconywa yi-mill, ngokuvamile oluyi-5%–7%, ukuze unciphise ukugoba, ukuphuka, ukushwabana, kanye nokuguqula imfucuza.
● Hlola amandla okuthamba, ukumelana nokudabuka, kanye nokugoqeka ndawonye esikhundleni sokuthenga ngesisindo sephepha kuphela.
● Khetha iphepha eliqinile futhi elihambisana neglue ukuze lisekele imigqa yemvilophu esheshayo egijima amakhulu noma ngisho nangaphezu kwe-1,000 ngomzuzu.

imibuzo ejwayelekile ukubuzwa

Yikuphi i-GSM engcono kakhulu kuma-envelope ephepha le-kraft?

Ama-envelope ebhizinisi ajwayelekile avame ukusebenzisa i-70–90 GSM, kuyilapho ama-mailer ekhathalogi evame ukudinga i-100–120 GSM. Ama-mailer anwetshiwe noma avikelayo angadinga isisindo esiphezulu kuye ngokuqukethwe, ukwakheka okugoqekayo, kanye nezinhloso zezindleko zeposi.

Kungani i-MD ne-CD zibalulekile ekukhiqizweni kwemvilophu?

Ukuqondiswa komshini kanye nokuqondiswa okuphambene kuthinta ukugoqeka, ukudabuka, kanye nokuqina kobukhulu. Ukuqondanisa ukuqondiswa kwefayibha ngendlela efanele kusiza ukuvimbela ukugoqeka okuqhekekile, imithungo ebuthakathaka, kanye nokuminyana emishinini yokuguqula esheshayo.

Yiliphi izinga lomswakama okufanele abathengi balicacisele iphepha le-kraft envelope?

Izigayo eziningi zihlose cishe umswakama ongu-5%–7%, kodwa ububanzi obufanele buncike esimweni sezulu, izimo zokugcina, kanye nesivinini sokuguqula. Umswakama ongalungile ungabangela ukugoba, ukuqhekeka, ukushwabana, noma ukusebenza kabi komshini.

Iphepha lokubhala kufanele liqine kangakanani ukuze lithunyelwe ngeposi elithembekile?

Kuzinhlelo zokusebenza eziningi zokuthumela iposi, abathengi bafuna amandla okudonswa komshini angaphezu kuka-5.0 kN/m, kuye ngendinganiso yokuhlola. Ukumelana nokudabuka kanye nokugoqeka kufanele futhi kuhlolwe ngesitayela semvilophu.

Ingabe iphepha le-kraft lingasebenza emishinini yemvilophu esheshayo?

Yebo, uma kuchazwe kahle. Imigqa yemvilophu ingasebenza izingcezu ezingu-500-1,200 ngomzuzu, ngakho-ke iphepha kumele linikeze ukuqina okuqhubekayo, ukugoba okubushelelezi, umswakama ozinzile, kanye nokwamukelwa kweglue okuthembekile.
