Iileyibhile zokuzincamathelisa luhlobo olubalulekileyo loshicilelo olusetyenziswa ngokubanzi kwipakethe yempahla, uthutho lolungiselelo, kunye nokuchongwa okwahlukeneyo. Kwi-self-adhesive label printing, i-lamination likhonkco elibaluleke kakhulu. Inokukhusela umgangatho weleyibhile, ukwandisa ukuqina, kunye nokuphucula ubuhle, ngaloo ndlela kuphuculwe ubomi benkonzo kunye nomgangatho weelebhile zokuzincamathelisa. Eli nqaku liza kwazisa inkqubo ye-lamination kunye nendlela ye-self-adhesive iilebhile emva kokushicilela, ijolise ekuncedeni abafundi baqonde iindlela ezahlukeneyo zokuzala, amanqaku zobugcisa, kunye nokukhethwa kwezinto, kwakunye nendlela yokuyilawula kakuhle inkqubo yokulambisa echanekileyo ukuqinisekisa umgangatho nokuthembeka.
Indima yeLeyibhile yokuLamination
Iileyibhile ezigqunywe phezulu zisetyenziselwa ukukhusela iilebhile ekonakalisweni kokusingqongileyo okufana namanzi, Imitha ye-UV, ukuqhawuka, njl. Ngokongeza ifilimu ecacileyo yokukhusela kumphezulu welebula, unokwandisa ubomi beleyibhile kwaye ugcine ukubonakala kwayo kucacile. Iileyibhile zokulayishwa zisenokomeleza ukuqina kweleyibhile kwaye zithintele imifanekiso okanye umbhalo okwiilebhile ukuba uphele ngokuhamba kwexesha. Iilaminates nazo zibonelela ngokhuseleko olongezelelweyo, ukuqinisekisa ukuba iilebhile azonakaliswa ngexesha lokuthumela kunye nokugcinwa. Zonke ezi zibonelelo zinokuphucula amava omthengi, ngaloo ndlela siphucula ulwazi lwebrendi.
Izinto eziLaminated
I-lamination of self-adhesive labels ngokuqhelekileyo isebenzisa izinto ezilandelayo:
Ifilimu yePolyester (Isilwanyana sasekhaya): Esi sixhobo sihlala ixesha elide kwaye asinamanzi, kwaye ibonelela ngoshicilelo oluphezulu lwemifanekiso kunye nokubhaliweyo.
Ifilimu yePolypropylene (I-PP): Ikhaphukhaphu kwaye icace kakhulu, le nto ibonelela ngoluhlu olukhuselekileyo olukhuselayo. Ifilimu ehlanganisiweyo yePP ecace ngokupheleleyo ngoku yeyona nto isetyenziswa kakhulu. Isizathu kukuba i-PP inexabiso eliphantsi kwaye yomelele ngakumbi kunezinye izinto ezininzi.
Ifilimu yePolyvinyl chloride (I-pvc): Esi sixhobo sinoqoqosho, kodwa ayinobuhlobo kangako nokusingqongileyo kune-PET okanye imathiriyeli yePP.
Ifilimu yePolyethylene (Pe): Esi sixhobo sithambile kwaye sifanelekile kwi-lamination lamination kwi-curved or irregular surfaces.
Ngenxa yeemfuno zeendleko, ukugquma kwezinto zokuqengqeleka kwephepha ngokusisiseko kuthathelwe indawo yitekhnoloji yeglazing. Kwishishini lelebhile, xa i-varnish ayikwazi ukuhlangabezana nokukhanya kunye neemfuno ze-matte, lamination yeyona ndlela ngqo. Sinokukhetha izinto ezifanelekileyo zokuthambisa ngokweemeko ezahlukeneyo zesicelo ukuqinisekisa ukuba ileyibhile ifumana olona khuselo lubalaseleyo kunye nokuqina..
Iindlela zokuLaminating
Iileyibhile iindlela lamination zidla yohlulahlulwe sheet-fed lamination kunye roll izinto lamination. Iphepha elifakwe kwi-sheet-fed laminated kumatshini wokuhlamba, kwaye izinto zomqulu zilaminethiwe kwisikhululo sokuthambisa somatshini weleyibhile okanye kumatshini okhethekileyo wokuthambisa. Iindlela ezimbini zokugquma zichazwe ngezantsi:
- I-Sheetfed iLaminated
I-Sheetfed lamination ibandakanya ukubeka iilebhile kwiphepha le-lamination material kunye nokusebenzisa ubushushu kunye noxinzelelo ukudibanisa i-lamination kunye nelebhile kunye.. Le ndlela ifanelekile kwiimeko apho iileyibhile zomntu ngamnye kufuneka zifakwe i-laminated, njengaxa iilebhile zinobukhulu obahlukeneyo okanye ukuphathwa okukhethekileyo kuyafuneka kwiilebhile. I-lamination ye-Sheetfed ingenziwa ngokusebenzisa i-laminators ye-manual okanye ezenzekelayo.
Zimbini iindlela zokwalamisa iilebhile zokuzincamathelisa ngeshiti, ezizezi instant ukutyabeka lamination kunye pre-ukwaleka film lamination.
1)Inkqubo yokudityaniswa kokudityaniswa kokwaleka okukhawulezileyo imi ngolu hlobo lulandelayo: okokuqala, i-adhesive ifakwe kumphezulu wefilimu ye-BOPP roll, kunye ne-solvent kwi-adhesive iguquguquka ngesixhobo sokumisa, kwaye ke iphepha lephepha lidityaniswe nefilimu yomqulu kwisikhululo sokudibanisa. Umdibaniso, ezimbini ziba enye phantsi kwe-extrusion ye-roller eshushu, kwaye inkqubo yokugquma ifilimu igqityiwe.
2)Ifilimu edityanisiweyo yangaphambili ibhekiselele ekugqunyweni kwangaphambili umaleko wokuncamathelisa okanye izinto zokuthambisa kumphezulu wefilimu edibeneyo.. Kukho iintlobo ezimbini zeefilimu, uhlobo oluncamathelayo olushushu olunyibilikayo kunye noxinzelelo olubuthathaka. Umatshini wokulambisa uxhotyiswe nge-roller embossing eshushu, kwaye ifilimu efakwe ngaphambili idibene nephepha lephepha ngexesha lokuhlamba. Ngaphantsi kwesenzo se-roller yokucinezela eshushu, i-adhesive iyanyibilika, ukwenzela ukuba ifilimu kunye nephepha zidibaniswe kwelinye. Ukuba usebenzisa ifilimu ehlanganisiweyo enoxinzelelo, unokucima umbane wokufudumeza kwaye uthembele kuphela kuxinzelelo lokubumba.
- Roll Material Lamination
I-Roll material lamination kukushicilela ifilimu yezinto eziphathekayo kunye neleyibheli kunye, kwaye ke badlule kunye kumatshini laminating ubushushu kunye noxinzelelo unyango. Le ndlela ifanelekile ukuveliswa kwenani elikhulu lamagama, enokuphucula ukusebenza kakuhle kwemveliso kunye nokunciphisa iindleko. I-Lamination yezinto zewebhu ingenziwa kwi-batch okanye imveliso eqhubekayo.
I-Web lamination idla ngokwahlulahlulwe ibe ziindidi ezimbini: Ifilimu ehlanganisiweyo yephepha elisezantsi idityaniswe kunye nephepha elingenamzantsi lidityaniswe nefilimu edibeneyo.
1)Ukunyibilikiswa kwefilimu edibeneyo yephepha kubhekiselele ekuhlanganiseni umaleko wephepha elixhasayo ngaphambili okanye ngasemva kwephepha., kwaye emva koko ugqume umaleko we-adhesive okanye i-laminating material kwiphepha elixhasayo, kwaye emva koko uncamathelise ileyibhile kuyo. I-Backed paper composite film lamination yindlela yemveli yokuthambisa, ethe yathatyathelw’ indawo yinkqubo yokusebenzisa ifilimu ehlanganisiweyo yephepha elingenasiphelo kwiminyaka yakutshanje.
2)Umgaqo we-laminating wefilimu edibeneyo ngaphandle kwephepha elisezantsi lifana nelo lefilimu edibeneyo kunye nephepha elisezantsi.. Ifilimu yephepha exhasayo iphinda iphinde iphindwe ngobuchwephesha bomhlaba (umphezulu woxinzelelo) yemathiriyeli yayo yokubuyisela iphepha lokuxhasa. Emva kokuba i-adhesive iboshwe phezulu, inokuxotyulwa ngaphandle kokushiya nayiphi na imikhondo yeglue. Izinto ezisetyenziselwa ifilimu yephepha elingenasiphelo ngokuqhelekileyo yifilimu yeBOPP yoxinzelelo oluphantsi. Ixabiso lefilim yephepha elingenasiphelo liphantsi, kwaye iyeyona nto isetyenziswa kakhulu ngoku lamination. Inzuzo yefilim edibeneyo yephepha elingenasiphelo kukuba inokuphucula ukusebenza kakuhle kwemveliso, ukunciphisa inkunkuma kwinkqubo yokuvelisa, kwaye kwangaxeshanye ukuphucula umgangatho wemveliso.
Kanjalo, kungakhathaliseki ukuba yeyiphi indlela yokulahla isetyenzisiweyo, umaleko okhuselayo unokuqulunqwa kumphezulu weleyibhile ukukhusela ileyibhile kumonakalo wokusingqongileyo.
Kwi-self-adhesive label printing, lamination linyathelo elibaluleke kakhulu, kuba inokwenza ileyibhile ibe ntle ngakumbi, yomelele, kwaye iguquguquke. Indlela echanekileyo ye-lamination kunye nokukhethwa kwezinto eziphathekayo kunokuqinisekisa umgangatho kunye nobomi benkonzo yeelebhile zokuzibamba. Ke ngoko, abavelisi bokushicilela kunye nabasebenzisi kufuneka banikele ingqalelo ekukhethweni kweendlela ezifanelekileyo zokuthambisa kunye nezixhobo, kunye nokulawula umgangatho wokuqinisekisa umgangatho wokugqibela weelebhile zokuzincamathela.
