Amaphuzu olwazibheka i-MODPE
1, ifilimu ye-MDOPE,okungukuthi, inqubo ye-MDO (unidirectional stretch) ekhiqizwe ukuqina okuphezulu kwefilimu ye-PE substrate polyethylene, enokuqina okuhle kakhulu, obala, ukumelana nokubhoboza nokumelana nokushisa, izici zayo zokubukeka nefilimu ye-BOPET ifana kakhulu nekhono lokubona inhlanganisela ye-PE ne-PE, ngaleyo ndlela idale i-100% ye-polyethylene ye-polyethylene edingekayo ekuhlanganisweni okuhlukile kokupakishwa okuhlukile amapulasitiki, i-Lapho igaywa kabusha, asikho isidingo sokuhlubula amapulasitiki ahlukene, okunciphisa kakhulu inkimbinkimbi yenqubo. Lokhu kuqanjwa kweqa imikhawulo yokupakisha okuyinhlanganisela evamile eyenziwe ngezinto eziningi ezahlukene ezingakwazi ukugaywa kabusha, futhi kuwukuqhubekela phambili okuhle kobuchwepheshe bokupakisha obuvumelana nezimo.
Amafilimu e-MDOPE ahlukaniswe amachungechunge amathathu:
Uchungechunge olujwayelekile lwe-MDOPE-T,
I-MDOPE-E high-barrier series,
I-MDOPE-S i-ultra high barrier series;
Ngokuthambile kwayo okuhle nokusebenza kokuphrinta, ukuzinza okuhle kakhulu kokushisa kanye nokuncipha okuphansi, ifilimu ye-MDOPE manje ingasetshenziswa njengefilimu yokunyathelisa izikhwama zezimpawu ezisemaceleni ayisishiyagalombili, izikhwama zokumunca umlomo wombhobho kanye nezikhwama zoziphu.
2. Isitifiketi se-GRS simelela i-Global Recycled Standard.
Kuyindinganiso yamazwe ngamazwe, yokuzithandela, yomkhiqizo wonke eklanyelwe ukuqinisekisa ukuthi okuqukethwe okugaywe kabusha kwemikhiqizo kufakwe ilebula enembile, kanye nokuqinisekisa ukuthi imikhiqizo yakhiwe ngokuhambisana nezindinganiso ezithile zesibopho sezemvelo nezenhlalo.
Kuyizinga lamazwe ngamazwe, lokuzithandela, lomkhiqizo wonke elidizayinelwe ukuqinisekisa ukuthi okuqukethwe okugaywe kabusha kwemikhiqizo kubhalwe ngokunembile nokuthi inqubo yokukhiqiza ihlangabezana namazinga athile esibopho sezemvelo nesomphakathi.
I-GRSPE(ene-pe egaywe kabusha)
Kusukela ngo-2022, i-Shanghai Xiangwei Packaging Co., Ltd ibisenza ucwaningo ngokuphrinta izikhwama ze-mono-material ezigaywa kabusha, futhi siqongelele ingcebo yolwazi kanye nesikhundla esivuthiwe, esihamba phambili embonini ekusetshenzisweni kwabo.
Ubunzima obuyinhloko bempahla eyodwa buvela ekwenzeni isikhwama, okudinga ukubambisana kwezinqubo ezilandelayo. Impahla ye-MDOPE idinga ukuba nomehluko othile wezinga lokushisa nefilimu yesisekelo ukuze kuzinziswe ukwakhiwa kwezikhwama.
Mayelana nokuphrinta, kudinga ukunakwa ukuphrinta ngokweqile, ukunamathela kweyinki, umphumela wokomisa (okusele kanye nokubala). Ubungako bezinto ezibonakalayo nokulawula ukungezwani.
Ku-composite, isidingo esifanayo sokulawula ukungezwani, ukushisa okomisa, ukomisa umthamo womoya omkhulu ngangokunokwenzeka, ukusetshenziswa kwe-high-density glue inqubo ye-roll net engajulile kungcono.
Ukwenziwa kwesikhwama kuyisinyathelo esibalulekile, ukwenza isikhwama kummese wokufaka uphawu okushisa ukwenza ukwelashwa okungenayo induku, zama ukushisa okuphansi kanye nemodi yokucindezela ephezulu yokukhiqiza;
Lapho sithenga izinto zokwakha, kufanele siqinisekise ukuthi indawo yokuhluka kwezinga lokushisa yendawo yokuncibilika eshisayo yendwangu kanye nezinto eziyisisekelo kufanele ibe nkulu;
Lawula ukushuba kokudonsa lapho wenza izikhwama, ezincane ziba ngcono;
Isakhiwo sibanzi ohlangothini ngangokunokwenzeka njengokuma mpo, uma isikhwama siyipuleti elincane lenza imigqa eminingi ngangokunokwenzeka, ukugwema ukuhamba ifilimu yezinto ezibonakalayo incane kakhulu;
Yenza izikhwama zoziphu lapho ukhetha uziphu ekhethekile enezinga lokushisa eliphansi, ukugwema ukuqhuma kwekhanda le-zipper.
Njengamanje, imboni ngokuvamile ikholelwa ukuthi ukumelana nokushisa kwefilimu ye-MDOPE kuhle, uhlobo lwesikhwama luyisicaba, kulula ukulawula i-curl.
Impahla ye-PE ye-lining kufanele ikhethwe ngokuya ngesimo esithile, isibonelo, uma udinga izakhiwo ezinhle zokuvimbela, ungakhetha i-EVOH-PE noma i-milky PE.
Uma kungekho sidingo esikhethekile, ungakhetha i-LDPE evame ukusetshenziswa!
UYELULEKA
1.Zama ukushaya ulayini odabula kalula lapho izindleko zekhasimende ziwusekela.
2.Ngaphambi kokwamukela i-oda (ngokwezinhlobo ezahlukene zezikhwama), kuchazwa ukuthi isakhiwo se-PE //PE se-flatness yomzimba wesikhwama sibi kancane kunezinye izinto (ungathatha ividiyo yakamuva yohlobo lwesikhwama esifanayo ukuze uchaze!) Umzimba wesakhiwo se-PE //PE awuphansi kakhulu kunezinye izinto (ungathatha ividiyo yakamuva yezikhwama ezifanayo ukuze ubonise!
Ukupakisha okukodwa okungaphinda kusetshenziswe kabusha kuyinkambiso, amabhizinisi aphrinta imibala ukwenza umsebenzi omuhle wezinqolobane zobuchwepheshe kufanele, kunconywa ukuthi lezi zindawo ezimbili ezilandelayo zizame kuqala:
1,Ukupakisha Okuqandisiwe
Sebenzisa i-PE yokudonsa okukodwa esikhundleni se-PET ne-BOPA enayiloni ukuze ukhiqize into eyodwa ye-PE yokupakishwa kwefriji, ikakhulukazi ukupakishwa kwefriji okungadingi ukusebenza kwesithiyo esiphezulu.
I-PE esikhundleni senayiloni, ekumelaneni nokubhoboza, ukumelana nezinyembezi kuzoncishiswa, kodwa kungahlangabezana nezidingo zokupakishwa okuqandisiwe, kumakhasimende amaningi angacabangela ukuphindaphinda. Uma kusetshenziswa i-PE esikhundleni se-PET, ukukhuphuka kwezindleko kuzoba phezulu. Sekukonke, ukushuba kwesikhwama kuyanda izindleko zokushintshwa ngokuqinisekile.
2,Ukushisa okujwayelekile kanye nemikhiqizo yokulondoloza isikhathi esifushane
Ibhizinisi lokuphrinta imibala lingaqala kusukela kuthempelesha yegumbi, ukupakishwa komkhiqizo wesiqinisekiso esifushane, okokuqala ukujwayela okokusebenza kanye nenqubo, ilinde okokusebenza ukuthi kuqhubeke ukuvuthwa.
Ngesikhathi esifanayo, ngokuya ngenqubo, kufanele futhi inake:
Ukukhiqizwa kokupakishwa kwempahla eyodwa, okuguquguqukayo okumbalwa okuzoba ngcono.
Ngokwesibonelo, xiangwei emaphaketheni Specialized umshini wokunyathelisa PE, umphumela muhle kakhulu, ukungezwani ingalawulwa kahle kakhulu, overprinting inembe kakhulu, kungakhathaliseki ukuthi uphakamisa futhi wehlise isivinini noma ukushintsha roll, ingalawulwa kahle kakhulu. Ikhwalithi yokuphrinta enoyinki we-DIC ingama-97% eduze nezinga lokuphrinta inayiloni.
Ngakho-ke, ekukhiqizeni okukodwa okupakishwayo okusebenziseka kabusha, zama ukucacisa okokusebenza okukhethekile ekukhiqizeni, ungashintshi ngokunganaki umugqa wokukhiqiza ukuze uqinisekise ukuzinza kwenqubo futhi ukwandise ukulawula kokulahlekelwa. Isibonelo, impahla ye-PE ekwenzeni izikhwama, nezinye izinto zokwakha zihluke kakhulu. Lesi sikhathi esikhundleni sokuvumela izinto ukuthi zivumelane nomshini wokwenza isikhwama, kunokuba uvumele umshini wokwenza isikhwama uvumelane nezinto ezibonakalayo: uma ku-batch ye-PE ukuze uzame kanye umshini, khona-ke ukusebenza kahle kuphansi kakhulu. Ngokuphambene nalokho, ikakhulukazi ucwaningo olulodwa lwe-PE lokupakisha kanye nokuthuthukiswa komshini wokwenza izikhwama, okuhlanganisa ingcindezi yokuvala ukushisa, inani lokulawula izinga lokushisa lokuvalwa kokushisa, njll., lingalungiswa ngokufanele ukuze kugwenywe into yokubeka uphawu ngokushisa ngokweqile noma okungamanga.
