Ifilimu yesiNtu yePlastiki yokuShweba yokuPakisha ibhotile

Ileyibhile yefilimu eshwabeneyo yobushushu yileyibhile yefilimu eprintwe kwifilimu yeplastiki okanye ityhubhu yeplastiki ene-inki ekhethekileyo. Ngethuba lenkqubo yokubhala, xa ishushu (malunga ne-70 ° C), ileyibhile eyanciphayo iya kulandela ngokukhawuleza i-contour yangaphandle yesitya. Iyashwabeka, kufutshane nomphezulu wesikhongozeli, iilebhile zefilimu ezishwabeneyo ubushushu ikakhulu ziquka iilebhile zemikhono ecuthekayo kunye neelebhile zokusonga ezicuthayo.

Iyashwabeka, kufutshane nomphezulu wesikhongozeli, iilebhile zefilimu ezishwabeneyo ubushushu ikakhulu ziquka iilebhile zemikhono ecuthekayo kunye neelebhile zokusonga ezicuthekayo.
Ileyibhile ye-sleeve ye-shrink yileyibhile ye-cylindrical eyenziwe ngefilimu enokufudumala njengobushushu njengento esisiseko emva kokushicilela. Ineempawu zokusetyenziswa ngokufanelekileyo kwaye ifaneleke kakhulu kwizikhongozeli ezinemilo ekhethekileyo. Iilebhile zemikhono efinyeziweyo zifuna ukusetyenziswa kwesixhobo sokuleyibhile esikhethekileyo ukufaka umkhono oshicilelweyo kwisingxobo. Okokuqala, izixhobo zokuleyibhela zivula ileyibhile ye-cylindrical sleeve etywiniweyo, enokuthi ngamanye amaxesha ifune ukubethelwa; ngokulandelayo, ileyibhile ye-sleeve inqunywe kwisayizi efanelekileyo kunye nemikhono kwisitya; kwaye emva koko unyango lobushushu usebenzisa umphunga, i-infrared okanye i-hot air channels , ukwenzela ukuba ileyibhile yomkhono ifakwe ngokuqinileyo kumphezulu wesikhongozeli.
Ngenxa yokukhanya okuphezulu kwefilimu ngokwayo, ileyibhile inombala oqaqambileyo kunye neglosi elungileyo. Nangona kunjalo, ngenxa yokuba kufuneka icuthwe ngexesha lokusetyenziswa, kukho ukungonakali kokuguqulwa kwepatheni, ngakumbi kwiimveliso eziprintiweyo kunye neelogo zebhakhowudi. Kufuneka idlule kuyilo olungqongqo kunye nolawulo lomgangatho woshicilelo, kungenjalo umgangatho webhakhowudi uya kuba ungafanelanga emva kokuba ipateni ikhubazekile. Iilebhile zokugoqa ezicuthayo zingasetyenziswa kusetyenziswa izixhobo zokuleyibheli eziqhelekileyo, ezifuna ukusetyenziswa kwezinto ezincamathelayo kunye namaqondo obushushu aphezulu. Ngethuba lenkqubo yokunciphisa, ekubeni i-adhesive kwi-party edibeneyo yefilimu iya kuvelisa uxinzelelo, kungcono ukusebenzisa i-adhesive eshushu enyibilikayo.
Ileyibhile yefilimu encitshiswa ubushushu iyinxalenye yentengiso yeeleyibhile, ekhula ngokukhawuleza, kwaye isabelo sayo sentengiso siyanda. Indawo eqaqambileyo kushishino loshicilelo lwelebhile. Kuqikelelwa ukuba imakethi yefilimu ecuthekayo yasekhaya iya kukhula ngesantya esingaphezulu kwama-20% kule minyaka mihlanu izayo.
Ishishini lokutya lelona shishini likhulu lokupakisha okucuthekayo. Ifilimu yokunciphisa ukushisa isetyenziswe ngokubanzi kwipakethe yokutya okukhawulezayo okuhlukahlukeneyo, ukutya kwe-lactic acid, iziselo, ukutya okuncinci, iitoti zebhiya, iiwayini ezahlukeneyo, iimveliso zezolimo kunye ne-sideline, ukutya okomileyo, iimveliso zendalo, njl njl. Imakethi ubukhulu becala ziinkampani ezinkulu zempahla zabathengi ezihamba ngokukhawuleza, ezinje ngeProcter & Gamble, Unilever, Shanghai Jahwa, njl. Utyalo-mali lokuqala loshicilelo lwe-gravure luphezulu, kodwa ukuqina okuphezulu kwepleyiti yegravure kunye nexabiso eliphantsi elihambelanayo lenza ibe lukhetho lokuqala lokucutheka koshicilelo lwefilimu. Ngaphezu koko, inxalenye yegraphic kwipleyiti yoshicilelo i-concave, ngoko ke umaleko we-inki oqinileyo, imibala eqaqambileyo kunye neengqimba ezityebileyo zinokufumaneka.
Ngokukhuthazwa kokuprintwa kwe-flexographic, ezinye iifilimu ezicuthayo nazo ziprintwa ngokuprintwa kwe-flexographic, ngokukodwa izinto ze-PE ezingenakukwazi ukumelana noxinzelelo olukhulu, kwaye uninzi lwazo zisebenzisa ii-CI-type flexographic machines. Kwintsimi engeyiyo yokutya, ukusetyenziswa kweelebhile zefilimu ezincitshiswayo zinyuka imihla ngemihla, ezifana neelebhile kunye neebhotile zebhotile, izitywina, izithambiso, amayeza, iimveliso zemichiza yemihla ngemihla, izinto zokubhala, ikhitshi, iimfuno zemihla ngemihla, njl. kwangaxeshanye, sele isetyenziswa ngokubanzi kwiimveliso ceramic, iiseti iti, amacandelo oomatshini, izinto zokwakha kunye nezinto zokuhamba.
