Qodobbada saameeya kharashka baakadaha

Horumarka joogtada ah ee heerarka nolosha, heerarka adag ee dadku kuma koobna cuntada lafteeda.Shuruudaha baakaddeeda ayaa sidoo kale kor u kacaysa.Baakadaha cuntadu waxay si tartiib tartiib ah u noqotay qayb ka mid ah alaabta laga soo bilaabo heerkeeda hoose.Waa muhiim in la ilaaliyo alaabta, Waa muhiimad weyn in la fududeeyo kaydinta iyo gaadiidka, kor u qaadida iibka, iyo kordhinta qiimaha alaabta.

Daabacaadda alaabta baakadaha dabacsan ee cuntada

① Daabacaadda Daabacaadda Cunnada dabacsan ee daabacaadda waxay inta badan ku saleysan tahay daabacaadda gravure iyo flexographic, oo ay ku xigto mashiinnada daabacaadda flexographic si ay u daabacaan filimada caagga ah (mashiinnada daabacaadda flexographic inta badan waxay sameeyaan khadadka wax soo saarka oo leh mashiinnada lamination qalalan), laakiin daabacaadda , marka la barbardhigo daabacaadda guud ee daabacaadda iyo Daabacaadda flexographic ee loo isticmaalo daabacaadda badeecadaha, waxaa jira kala duwanaansho badan.Tusaale ahaan: Daabacaadda baakadaha dabacsan waxay ku daabacan tahay dusha sare ee substrate-ka duuban.Haddii ay tahay filim hufan, qaabka waxaa laga arki karaa dhabarka.Mararka qaarkood waxaa lagama maarmaan ah in lagu daro lakabka rinjiga cad ama isticmaal habka daabacaadda gudaha.

② Qeexida habka daabacaadda dhabarka Daabacaadda dambe waxaa loola jeedaa hab daabacaad gaar ah oo isticmaalaya saxan daabacan oo leh muuqaal iyo qoraal si loogu wareejiyo khad gudaha gudaha alaabta daabacaadda, si sawirka togan iyo qoraalka loogu muujiyo xagga hore. ee shayga daabacan.

③ Faa'iidooyinka Liyiin

Marka la barbar dhigo daabacaadda dusha sare, walxaha daabacan ee dahaarka leh waxay leeyihiin faa'iidooyinka inay noqdaan kuwo dhalaalaya oo qurux badan, midab leh / aan dhumin, qoyaan-cadeyn iyo adkaysi u leh.Ka dib marka daabacaadda dahaarka la isku daro, lakabka khadku wuxuu u dhexeeyaa laba lakab oo filim ah, kaas oo aan wasakheynin alaabta baakadaysan.

Baakadaha Jeex-raac ee Baakadaha Baakadaha Barkinta Baakadaha Baakadaha Dib-u-noqoshada Baakadka Baakadaha Dareeraha Baakadaha Baakadaha Joogtada ah ee Baakadaha Warqadda Booshka Baakadaha Booshka Baakadaha

Isku-darka alaabta baakadaha dabacsan ee cuntada

① Habka isku-darka qoyan: Ku dhaji lakabka koollada biyaha-milmi leh ee dusha sare ee walxaha saldhigga ah (filim caag ah, aluminium aluminium), ku dar walxaha kale (warqad, cellophane) iyada oo loo marayo rullaluistemadka cadaadiska, ka dibna ku qalaji si kulul. tunnel qalajinta Noqo xuub isku dhafan.Habkani wuxuu ku habboon yahay baakadaha cuntada qalalan.

② Habka qallajinta qallalan: marka hore mari xabagta ku salaysan dareeraha si siman substrateka, ka dibna u dir tunnelka qallajinta kulul si ay si buuxda u uumi-baxdo dareeraha, ka dibna isla markiiba ku dheji lakab kale oo filim ah.Tusaale ahaan, filimka polypropylene ku jihaysan (OPP) ayaa guud ahaan lagu daraa walxo kale iyada oo la adeegsanayo habka laaminta qalalan ka dib daabacaadda gudaha.Qaab dhismeedka caadiga ah waa: filimka polypropylene ku jihaysan bixially (BOPP, 12 μm), foil aluminium (AIU, 9 μm) iyo filim polypropylene fidsan (CPP, 70 μm).Nidaamku waa in la isticmaalo qalabka daahan rullaluistemadka ah si siman loo dahaadho dareeraha ku salaysan "budada koollada qallalan" ee walxaha saldhigga ah, ka dibna u dir tunnelka qalajinta kulul si ay si buuxda u uumi-baxdo dareeraha ka hor inta aanad ku dhejin lakab kale oo filim ah iyadoo la isticmaalayo a rullaluistemadka laminating.

③ Habka isku-darka ka-baxa wuxuu ka soo saaraa daahyada la shubay ee polyetylenka oo kale ah oo ka soo baxaya dillaaca T caaryada, oo ku cadaadiya rullalulatada qanjaruufka ah, oo ku daadi warqad ama filim loogu talagalay daahan polyetylen, ama waxay siisaa filimo kale qaybta quudinta warqadda labaad.U isticmaal polyetylen sida lakabka xabagta ee isku xidhka.

④ Habka isku dhafan ee kulul ee dhalaalay: Polyethylene-acrylate copolymer, ethylene acid-ethylene copolymer, iyo wax paraffin ah ayaa la kululeeyaa oo la wada dhalaalay, ka dibna lagu daboolaa substrate-ka, isla markiiba lagu daraa walxo kale oo isku dhafan ka dibna la qaboojiyo.

⑤ Habka isku dhafka ah ee lakabka badan

Noocyo kala duwan oo caag ah oo leh sifooyin kala duwan ayaa la dhex maraa meelo badan oo dibadda ah waxaana lagu sii daayaa caaryada si ay u sameeyaan filim.Nidaamkani uma baahna koollo ama dareerayaasha organic u dhexeeya lakabyada, iyo filimku ma laha ur ama wax qabad waxyeello leh, taas oo ka dhigaysa mid ku habboon baakadaha cuntada oo leh nolol shelf dheer.Tusaale ahaan, qaabka guud ee LLDPE/PP/LLDPE waxa uu leeyahay daah-furnaan wanaagsan oo dhumucdiisuna guud ahaan waa 50-60μm.Haddii ay leedahay nolol shelf dheer.In ka badan shan lakab oo filimo is-daba-joog ah ayaa loo baahan yahay, lakabka dhexena wuxuu ka samaysan yahay alaab-caqabad sare leh PA, PET iyo EVOH.
