iindaba

Intshayelelo: Ukuguquguquka kweleyibhile yefilimu eshwabeneyo yomelele kakhulu.Inokuhonjiswa ngeplastiki, isinyithi, iglasi kunye nezinye izitya zokupakisha.Ileyibhile yomkhono wefilimu iShrink ithandwa ngakumbi kwimarike kuba inokudibanisa iipateni ezikumgangatho ophezulu kunye neemilo ezahlukileyo.Eli nqaku labelana ngolwazi olufanelekileyo lwemveliso yeleyibhile ecuthayo, umxholo wereferensi yabahlobo:

Ucuthe ileyibhile yesigqubuthelo sefilimu

Ileyibhile yomkhono wefilimu iShrink yiseti yefilimu eprintwe kwifilimu yeplastiki okanye ityhubhu yeplastiki.

01 Iimpawu

I-1) Ukucutshungulwa kweleyibhile yomkhono wefilimu ilungile, ukupakisha ukutywinwa, ukuthintela ungcoliseko, ukukhuselwa kakuhle kwempahla;

I-2) Isigqubuthelo sefilimu sisondele kwimpahla, ukupakishwa kuhambelana, kwaye kunokubonisa imilo yempahla, ngoko ifanelekile kwizinto ezingaqhelekanga ezinzima ukupakisha;

I-3) I-Shrinkage film cover label label, ngaphandle kokusetyenziswa kwe-adhesive, kwaye inokufumana ukucaca okufanayo njengeglasi;

I-4) Ilebula ye-sleeve yefilimu ye-shrink inokubonelela nge-360 ° yonke imihlobiso ejikelezayo kwisitya sokupakisha, kwaye inokushicilela ulwazi lwemveliso efana nenkcazo yemveliso kwilebula, ukwenzela ukuba abathengi banokuqonda ukusebenza kwemveliso ngaphandle kokuvula ipakethe;

I-5) Ukuprintwa kweleyibhile yefilimu ye-shrink yokushicilela kwifilimu (isicatshulwa kunye nesicatshulwa singaphakathi kwi-sleeve yefilimu), enokuthi idlale indima yokukhusela i-blot, kunye nokuxhatshazwa kokugqoka kwelebula kungcono.

Uyilo lweleyibhile

Uyilo lwepateni yokuhlobisa kwikhava yefilimu kufuneka inqunywe ngokobunzima befilimu.Xa siyila ipateni, kufuneka siqale sicacise izinga lokucutheka elithe tye kunye nelobude befilimu, kunye nesantya esivumelekileyo sokuncipha kwesalathiso ngasinye emva kokupakishwa kunye nempazamo evumelekileyo yokuguqula ipateni yokuhombisa emva kokuncipha, ukuze kuqinisekiswe ukuba iphethini kunye nombhalo emva kokuncipha kunokubuyiselwa ngokuchanekileyo.

Ubunzima befilimu kunye nokuncipha

Izinto ezisetyenziselwa ukucutha ileyibhile yesigqubuthelo sefilimu kufuneka zigxininiswe kwizinto ezintathu: iimfuno zokusingqongileyo, ubukhulu befilimu kunye nokusebenza kokuncipha.

Ubunzima befilimu bunqunywe ngokusekelwe kwintsimi yesicelo selebula kunye nexabiso leendleko.Kakade ke, ixabiso aliyiyo eyona nto ibalulekileyo, njengoko ifilimu nganye yahlukile, kwaye umsebenzisi kunye nomshicileli wophawu kufuneka bachonge ifilimu kunye nenkqubo efanelekileyo kwizinto eziphathekayo ngaphambi kokusayina isivumelwano.Ukongezelela, izixhobo zokusebenza ezifunekayo izikhombisi kunye nezinye izinto zenkqubo nazo zichaphazela ngokuthe ngqo ukukhethwa kobunzima.Ubunzima befilimu yeleyibhile yefilimu ecuthekayo idla ngokuba yi-30-70 μm, phakathi kwayo, ifilimu ye-40μm kunye ne-50μm isetyenziswa ngakumbi.Ukongezelela, izinga lokunciphisa ifilimu liyadingeka, kwaye isantya sokunciphisa (TD) siphezulu kunelongitudinal (MD) yokunciphisa izinga.Izinga lokucutheka elinqamlezayo lezinto eziqhelekileyo yi-50% ~ 52% kunye ne-60% ~ 62%, kwaye inokufikelela kwi-90% kwiimeko ezizodwa.Ireyithi yokucutheka kwelongitudinal kufuneka ibe yi-6% ~ 8%.Xa usenza iileyibhile zemikhono yefilimu ecuthekileyo, zama ukukhetha izixhobo ezinokuncipha okuncinci kwe-longitudinal.

Izinto zefilimu ezibhityileyo

Izinto eziphambili zokwenza iilebhile zefilimu ecuthekileyo yifilimu ye-PVC, ifilimu ye-PET, ifilimu ye-PETG, ifilimu ye-OPS, njl. njl. Ukusebenza kwayo ngolu hlobo lulandelayo:

1) inwebu yePVC

Ifilimu yePVC yenye yezona zinto zisetyenziswa kakhulu kwifilimu.Ixabiso layo liphantsi, uluhlu lwe-shrinkage yeqondo lokushisa likhulu, imfuno yomthombo wokushisa ayikho phezulu, umthombo oyintloko wokushisa ukushisa umoya oshushu, i-infrared okanye indibaniselwano yezi zibini.Kodwa i-PVC inzima ukuyibuyisela kwakhona, xa itshisa igesi enetyhefu, ayilunganga ukukhusela okusingqongileyo, eYurophu, iJapan iye yavala ukusetyenziswa kwe.

2) Ifilimu ye-OPS

Njengenye ifilimu ye-PVC, ifilimu ye-OPS isetyenziswe ngokubanzi.Inokusebenza kakuhle kokucutheka kwaye ilungele nokusingqongileyo.Imakethi yangaphakathi yale mveliso inqabile, kwaye okwangoku i-OPS ekumgangatho ophezulu ixhomekeke ikakhulu ekuthengisweni kumazwe angaphandle, ethe yaba yinto ebalulekileyo ethintela uphuhliso lwayo.

3) Ifilimu ye-PETG

Ifilimu ye-PETG ye-copolymer ayinanzuzo kuphela ekukhuselweni kwendalo, kwaye inokulungiswa kwangaphambili izinga lokucutheka.Nangona kunjalo, ngenxa yokuba izinga lokuncipha likhulu kakhulu, liya kulinganiselwa ekusebenziseni.

4) Ifilimu ye-PET

Ifilimu ye-PET yimathiriyeli yefilimu evunyiweyo kwihlabathi evumelana nobushushu.Iimpawu zayo zobugcisa, iipropati ezibonakalayo, uluhlu lwezicelo kunye neendlela zokusetyenziswa zisondele kwifilimu ye-PVC ye-thermal shrink, kodwa ixabiso lingabizi kakhulu kune-PETG, ifilimu ye-shrink ehamba phambili ye-unidirectional.Izinga layo lokucutha elithe tyaba liya kuthi ga kwi-70%, izinga lokucutha longitudinal lingaphantsi kwe-3%, kwaye i-non-toxic, i-pollution-free, iyona nto ifanelekileyo yokuthatha indawo ye-PVC.

Ukongeza, ityhubhu yefilimu eshwabeneyo iphinde ibe yimveliso yeleyibhile yefilimu ecuthekayo, kwaye kwimveliso inokwenziwa ngaphandle kwe-suture.Xa kuthelekiswa nefilimu ethe tyaba ethe tyaba, iindleko zokuvelisa ileyibhile yefilimu eshwabeneyo enetyhubhu yefilimu eshwabeneyo isezantsi, kodwa ukuprintwa kumphezulu womzimba wombhobho kunzima kakhulu ukufezekisa.Ngelo xesha, imifanekiso kunye nemifanekiso yeleyibhile ye-tube yefilimu enokufudumala ingashicilelwa kuphela kumphezulu wefilimu, ekulula ukuyinxiba ngexesha lokuthutha kunye nokugcinwa, ngaloo ndlela ichaphazela umphumo wokupakisha.

03 imveliso egqityiweyo

Ukushicilela

Shicilela kwifilimu ekhethiweyo.Okwangoku, ukuprintwa kwefilimu ye-shrinkage ikakhulu kusetyenziswa ukuprintwa kwe-intaglio, kusetyenziswa ii-inki ezisekelwe kwi-solvent, elandelwa yi-flexographic printing.Ngophuhliso lweteknoloji yoshicilelo lwe-flexo, imibala yokushicilela igqamile kwaye icacile, ithelekiseka ne-gravure printing, kunye ne-gloss enzima kunye nephezulu ye-gravure.Ukongeza, ukuprintwa kwe-flexo usebenzisa i-inki esekelwe emanzini, ilungele ngakumbi ukukhuselwa kwendalo.

Ukusika

Ngomatshini wokuqhawula umsebenzi ophezulu, ifilimu ye-reel eprintiweyo inqunyulwe ngobude, kwaye inxalenye yecala yefilimu iphathwa ukuze iyenze igudileyo, icwecwe kwaye ingabi crimp.Xa usebenzisa i-scutters, ingqalelo kufuneka ihlawulwe ukuphepha i-blade eshushu, kuba i-blade eshushu iya kubangela ukuba ifilimu inqunywe inxalenye yombimbi.

Ukuthunga

Ifilimu ye-slit yaxutywa embindini ngomatshini we-suture, kwaye umlomo wetyhubhu wawubophelelwe ukwenza umkhono wefilimu ofunekayo ukupakishwa.Isibonelelo sezinto eziphathekayo ezifunekayo kwi-suturing sixhomekeke ekuchanekeni kwe-suture kunye nobuchule bomqhubi.Esona sibonelelo siphezulu se-suturing yi-10mm, ngokuqhelekileyo yi-6mm.

Ukusika okunqamlezileyo

Umkhono wefilimu upakishwe ngaphandle kwempahla kwaye unqunyulwe ngokuthe tye ngokwesayizi yokupakisha nge-scutter.Ifilimu ye-shrinkage kwiqondo lokushisa elifanelekileyo lokufudumeza, ubude nobubanzi bayo buya kuba ne-contraction ebukhali (15% ~ 60%).Ngokuqhelekileyo kuyafuneka ukuba ubungakanani befilimu bumalunga ne-10% enkulu kunobona bukhulu bemilo yempahla yorhwebo.

Ubushushu buyancipha

Fudumeza ngepaseji eshushu, i-oveni eshushu okanye umpu wokutshiza womoya oshushu.Ngeli xesha, ileyibhile yokucutha iya kucutheka ngokukhawuleza ecaleni kwendlela yangaphandle yesikhongozelo, kwaye umphandle wesikhongozeli uthotyelwe ngokusondeleyo, wenze umaleko okhuselayo weleyibhile ohambelana ngokupheleleyo nokumila kwesitya.

Kwinkqubo yokuveliswa kweleyibhile ye-sleeve yefilimu eshwabeneyo, ukufunyanwa okungqongqo kwenkqubo nganye kufuneka kuqhutywe ngumatshini okhethekileyo wokufumanisa ukuqinisekisa ukuchaneka kwemveliso.

04 Ubungakanani besicelo

Ukulungelelaniswa kweleyibhile ye-shrinkage yomelele kakhulu, engasetyenziselwa ukuhlobisa umphezulu kunye nokuhlobisa umthi, iphepha, isinyithi, iglasi, i-ceramic kunye nezinye izitya zokupakisha.Isetyenziswa ngokubanzi kwipakethe kunye nokuhombisa ukutya, iimveliso zemichiza yemihla ngemihla kunye neemveliso zemichiza, njengazo zonke iintlobo zeziselo, izithambiso, ukutya kwabantwana, ikofu njalo njalo.Kwintsimi yeelebhile zeziyobisi, iphepha liselona candelo liphambili, kodwa uphuhliso lokupakishwa kwefilimu luye lwanda ngokukhawuleza.Okwangoku, isitshixo kuphuhliso lweleyibhile yefilimu ecuthekileyo kukunciphisa iindleko, ngale ndlela kuphela inokuphucula ukukhuphisana kwaye sizame ukufumana isabelo esikhulu semarike.
