iindaba

Ileyibhile ye-Shrink iguquguquka kakhulu, iplastiki, isinyithi, iglasi kunye nezinye izikhongozeli zokupakisha zinokuhonjiswa, zicuthe iileyibhile zemikhono yefilimu ngenxa yokudityaniswa kweepateni ezikumgangatho ophezulu kunye nemodeli eyahlukileyo, ithandwa ngakumbi kwimarike.Eli phepha lichaza iimpawu kunye neenzuzo zeleyibhile yefilimu efinyeziweyo kunye nomgaqo wokukhetha izinto eziphathekayo, umxholo wereferensi yabahlobo:

Ileyibhile yomkhono wefilimu unciphise

Iseti yefilim eshwabenekayo yeelebhile ngokuyimfuneko yeyodidi lwefilimu eshwabeneyo nobushushu, yifilimu yeplastiki okanye iilebhile ezivelayo eziprintwe kumbhobho weplastiki, ingakumbi iPE, iPVC, iPET, efana nohlobo oluqhelekileyo lwefilimu eshwabeneyo ngenxa yokuba iseti yefilimu eshwabeneyo. yindlela yokuqhelaniswa nenkqubo yokuvelisa, kunye nenkqubo yokusebenzisa ukufudumala kwefilimu yeplastiki ye-thermoplastic.Ngoko ke, phambi kokuyilwa kwepateni yomphezulu, kufuneka siqwalasele izinga lokucutha okuthe tye kunye nobude bezinto eziphathekayo, kunye nempazamo yokuguqulwa evunyelwe kuzo zonke iinkalo zombhalo wokuhombisa emva kokunciphisa, ukwenzela ukuba kuqinisekiswe ukucuthwa okuchanekileyo kwepateni. , umbhalo kunye nekhowudi yebha icuthelwe kwisikhongozeli.

01 Aizinto eziluncedo

Ileyibhile ye-Shrink-wrap yileyibhile eseti yefilimu eprintwe kwifilimu yeplastiki okanye ityhubhu yeplastiki.Inezi mpawu zilandelayo:

I-1) Ukucutshungulwa kweleyibhile yomkhono wefilimu kukulungele, ukupakisha ukutywinwa, ukuchasana nongcoliseko, ukukhuselwa kakuhle kwempahla;

I-2) Ikhava yefilimu isondele kwimpahla, iphakheji idibene, kwaye ingabonisa imilo yempahla, ngoko ifanelekile kwimpahla engaqhelekanga enzima ukuyipakisha;

I-3) Ileyibhile yefilimu yefilimu eyanciphayo, ngaphandle kokusetyenziswa kwe-adhesive, kwaye inokufumana ukucaca okufanayo njengeglasi;

I-4) Ilebula ye-Shrink-isongelwe inokubonelela nge-360 ° umhlobiso wesitya sokupakisha, kwaye inokushicilela ulwazi lwemveliso efana nenkcazo yemveliso kwilebula, ukwenzela ukuba abathengi banokuqonda ukusebenza kwemveliso ngaphandle kokuvula ipakethe;

I-5) Ukushicilelwa kweleyibhile ye-sleeve yefilimu ye-shrink yeyokushicilelwa kwifilimu (isicatshulwa kunye nomfanekiso ungaphakathi kwi-sleeve yefilimu), enokukhusela imbonakalo kwaye inokumelana nokunxiba okungcono.

02 Yila izinto ezibalulekileyo kunye nemigaqo yokukhetha imathiriyeli

Uyilo lweleyibhile

Uyilo lwepateni yokuhlobisa kwifilimu kufuneka inqunywe ngokobunzima befilimu.Xa uyila ipateni, kuyimfuneko ukucacisa isantya sokucutheka esinqamlezileyo kunye nobude befilimu, kunye nezinga lokucutheka elivumelekileyo kwicala ngalinye emva kokupakishwa kunye nempazamo evumelekileyo yokuguqula ipateni yokuhombisa emva kokuncipha, ukuze kuqinisekiswe ukuba ipateni kunye nombhalo emva kokuncipha kunokubuyiselwa ngokuchanekileyo.

Ubunzima befilimu kunye nokuncipha

Izinto ezisetyenziselwa iileyibhile zefilimu ezicuthekayo kufuneka zigxininise kwizinto ezintathu: iimfuno zokusingqongileyo, ubukhulu befilimu kunye nokusebenza kokuncipha.

Ubuninzi befilimu bunqunywe ngokusekelwe kwintsimi yesicelo kunye neendleko zelebula.Ngokuqinisekileyo, ixabiso aliyiyo eyona nto ithatha isigqibo, njengoko ifilimu nganye yahlukile kwaye bobabini umsebenzisi kunye nomshicileli weleyibhile kufuneka bacace malunga nefilimu kunye nenkqubo efanelekileyo kwizinto eziphathekayo ngaphambi kokusayina.Ukongeza, isalathiso esifunwa zizixhobo zokucubungula kunye nezinye izinto zenkqubo nazo zichaphazela ngokuthe ngqo ukhetho lobunzima.Ngokuqhelekileyo kufunwa ukuba ubukhulu befilimu yelebula ye-shrink-sleeve yi-30-70 μm, phakathi kwayo i-40μm kunye ne-50μm isetyenziswa ngokuqhelekileyo.

Ukongezelela, ifilimu ye-shrinkage rate ineemfuno ezithile, kwaye i-lateral (TD) i-shrinkage rate iphezulu kune-longitudinal (MD) yokunciphisa izinga.I-shrinkage enqamlezileyo yezinto eziqhelekileyo yi-50% ~ 52% kunye ne-60% ~ 62%, kwaye inokufikelela kwi-90% kwiimeko ezizodwa.Izinga lokucutheka kwexesha elide elifunekayo kwi-6% ~ 8%.Xa usenza iileyibhile zemikhono yefilimu ecuthekayo, izinto ezinokuncipha kwe-longitudinal encinci kufuneka zikhethwe kangangoko kunokwenzeka.

03 Izixhobo zefilimu 

Izinto zokwenza ileyibhile yefilimu ecuthekileyo yokugubungela ifilimu ye-PVC (PVC), ifilimu yesilwanyana (i-polyester), ifilimu yepegi (i-polyester elungisiweyo), ifilimu ye-ops (i-polystyrene e-oriented), njl njl. Ukusebenza kwayo ngolu hlobo lulandelayo:

Ifilimu yePVC yePVC 

ifilimu yeyona nto isetyenziswa kakhulu ngoku.Ixabiso eliphantsi, linoluhlu olukhulu lokucutheka kobushushu kwaye ayizizo iimfuno eziphezulu zomthombo wobushushu.Owona mthombo wobushushu wokusetyenzwa kukudityaniswa komoya oshushu, ukukhanya kwe-infrared okanye zombini.Nangona kunjalo, i-PVC inzima ukuphinda isetyenziswe kwakhona, xa igesi evuthayo, engahambelani nokukhuselwa kwendalo, ivaliwe eYurophu naseJapan.

OPSifilimu

Njengendawo yeefilimu zePVC, iifilimu ze-OPS zisetyenziswe ngokubanzi.Ukusebenza kwayo kokucutheka kuhle, kukwanceda ukukhuselwa kwendalo.Imarike yasekhaya yale mveliso iyanqongophala, kwaye okwangoku, i-OPS ekumgangatho ophezulu kakhulu ixhomekeke ekungenisweni kweli lizwe, nto leyo eye yaba yinto ebalulekileyo ethintela uphuhliso lwayo.

PETGifilimu 

Ifilimu ye-PETG ye-copolymer ayincedi kuphela ekukhuselweni kokusingqongileyo, kodwa inokulungelelanisa izinga lokunciphisa kwangaphambili.Nangona kunjalo, ngenxa yokuncipha okugqithisileyo, kuya kuthintelwa ukusetyenziswa.

PETifilimu 

Umboniso bhanyabhanya we-PET luhlobo lwefilimu evunyiweyo kwihlabathi jikelele lohlobo lwe-thermal shrinkage.Iimpawu zayo zobugcisa, iipropati ezibonakalayo, uluhlu lwezicelo kunye neendlela zokusetyenziswa zisondele kwifilimu yokunciphisa i-PVC ye-thermal, kodwa ibiza kakhulu kune-PETG, eyona filimu yokunciphisa i-unidirectional ephezulu kakhulu ngoku.Izinga layo lokucutha elinqamlezayo lingama-70%, izinga lokucutheka kwe-longitudinal lingaphantsi kwe-3%, kwaye ayinayo ityhefu kunye nongcoliseko, eyona nto ifanelekileyo yokutshintsha i-PVC.

04 Ukuprintwa kweleyibhile kwikhava yefilimu Iprintwe kwiifilimu ezikhethiweyo. 

Okwangoku, ukuprintwa komkhono wefilimu enciphayo kusetyenziswa ikakhulu kushicilelo lwegravure, inki yoshicilelo enyibilikayo, elandelwa kukuprintwa okuguquguqukayo.Ngokuphuhliswa kobuchwepheshe be-flexo, umbala wokushicilela ugqamile kwaye ucacile, unokuthelekiswa ne-gravure printing, kunye ne-gloss enzima kunye nephezulu ye-gravure.Ukongezelela, i-flexo isebenzise ngakumbi inki esekelwe emanzini, ilungele ngakumbi ukukhuselwa kwendalo.Ukusika ngomatshini wokusika owenziweyo ophezulu kuya kusetyenziswa ukusika ifilimu ye-reel eprintiweyo yokusika i-longitudinal cutting, kwaye inxalenye yomgca wefilimu iya kucutshungulwa ukuze ihambe kakuhle, ilula kwaye ingabikho.Xa usebenzisa umatshini wokusika, qaphela ukuba ugweme ukutshisa i-blade, kuba i-blade eshushu inokubangela ukuba ifilimu inqunywe ukuba ibe mibimbi.I-suture yefilimu emva kokusika i-longitudinal iqhutywe ngumshini we-suture, kwaye umlomo wombhobho ubophelelwe ukwenza umkhono we-membrane ofunekayo ukupakishwa.Umda wezinto ezifunekayo kwi-suture uxhomekeke ekuchanekeni kwe-suture kunye nobuchule bomqhubi.Ubuninzi obucetyiswayo be-suture yi-10mm, ngokuqhelekileyo yi-6mm.Ukusika okuguquguqukayo kunye nokusongela isigqubuthelo sefilimu ngaphandle kwemveliso, kunye nokusika ifilimu ngokuthe tye ngokobukhulu bayo bokupakisha.Kwiqondo lokushisa elifanelekileyo lokufudumeza, ubude kunye nobubanzi befilimu ye-shrinkage buya kuncipha ngokukhawuleza (15% ~ 60%).Ngokubanzi, ubungakanani befilimu bufuneka ukuba bube malunga ne-10% enkulu kunobukhulu bobungakanani bemilo yemveliso.Ukunciphisa ubushushu bufudunyezwa ngepaseji eshushu, i-oveni eshushu, okanye umpu wokutshiza womoya oshushu.Kweli nqanaba, ileyibhile yokushwabana iya kukhawuleza ishwabane ecaleni kwekhonta engaphandle yesikhongozelo, ilingane ngokuqinileyo necontour yangaphandle yesikhongozeli, yenze umaleko okhuselayo weleyibhile ohambelana ngokupheleleyo nokumila kwesikhongozeli.Kwinkqubo yokuveliswa kweleyibhile yefilimu ye-shrinkage, kuyimfuneko ukuba kuqhutywe ubhaqo olungqongqo lwenkqubo nganye ngomatshini okhethekileyo wokufumanisa ukuqinisekisa ukuchaneka kwemveliso.Umda osebenzayo weleyibhile ye-shrink uguquguquka kakhulu, ungasetyenziselwa ukuhombisa umphezulu, umhombiso womthi, iphepha, isinyithi, iglasi, iiseramikhi kunye nezinye izitya zokupakisha, ezisetyenziswa kakhulu ekutyeni, iimveliso zemichiza yemihla ngemihla, ukupakishwa kweekhemikhali kunye nokuhombisa, njengeziselo ezahlukahlukeneyo, izinto zokuthambisa, ukutya kwabantwana, ikofu njalo njalo.
