一, Buga kayan marufi masu sassaucin ra'ayi
①Hanyar bugawa
Abinci m marufi bugu ne yafi gravure bugu da flexographic bugu, biye da yin amfani da flexographic bugu na'ura don buga filastik fim (flexographic bugu na'ura da busassun hada na'ura yawanci samar da wani samar line), amma akwai da yawa bambance-bambancen idan aka kwatanta da general gravure bugu kuma flexographic bugu da aka yi amfani da shi wajen bugu da bugu na kayayyaki. Misali, ana aiwatar da bugu mai sassauƙa a saman juzu'in mirgine. Idan fim ne mai haske, ana iya ganin tsarin daga baya, kuma wani lokaci ana buƙatar bugu na farin fenti, ko kuma a yi amfani da tsarin bugawa na ciki.
②Ma'anar tsarin bugu na ciki
Buga na ciki yana nufin hanyar bugu na musamman da ke amfani da farantin bugu na hoton baya don canja wurin tawada zuwa gefen ciki na kayan bugu na gaskiya, ta yadda za a nuna kyakkyawan hoto a gaban abin da aka buga.
③Amfanin Indiya
Idan aka kwatanta da samfuran da aka buga a saman, samfuran da aka buga na ciki suna da fa'idodin haske da kyau, launi mai haske / sauri, danshi da juriya; Bayan bugu na ciki, ana yin sandwiched ɗin tawada a tsakanin yadudduka na fim ɗin, wanda ba zai ƙazantar da marufi ba.
二, Haɗin kayan marufi masu sassauƙan abinci
①Hanyar hadewar rigar
A Layer na ruwa mai narkewa m yana mai rufi a kan saman kayan tushe (fim ɗin filastik, foil na aluminum), wanda aka haɗa tare da wasu kayan (takarda, cellophane) ta hanyar abin nadi na matsa lamba, sa'an nan kuma ya bushe a cikin fim din ta hanyar zafi. tashar bushewa. Wannan hanya tana amfani da busasshen abinci marufi.
②Hanyar hadaddiyar bushewa
Na farko, a ko'ina gashi da sauran ƙarfi tushen m a kan substrate, sa'an nan kuma aika shi a cikin zafi bushe tashar sa sauran ƙarfi volatilize, sa'an nan nan da nan fili tare da wani Layer na fim. Misali, fim ɗin polypropylene da aka shimfiɗa (OPP) gabaɗaya an haɗa shi tare da wasu kayan ta hanyar busassun hadadden tsari bayan bugu na ciki. Tsarin tsari shine: fim ɗin polypropylene mai daidaitacce (BOPP, 12μ m) Aluminum foil (AIU, 9μ m) Kuma unidirectionally mike polypropylene film (CPP, 70μ m).Tsarin shine a ko'ina gashi nau'in ƙarfi-nau'in "bushewar foda" akan kayan tushe tare da na'urar abin abin nadi, sannan aika shi cikin tashar bushewa mai zafi don cika ƙarfi da ƙarfi, sa'an nan kuma haɗa shi da wani Layer na fim tare da abin nadi mai hadewa.
③Extrusion mahadi hanya
Labule-kamar narkakkar polyethylene extruded daga tsaga na T mold aka matsa da clamping abin nadi da salivated a kan takarda ko fim don polyethylene shafi, ko wasu fina-finai ana kawota daga na biyu takarda ciyar part, da kuma polyethylene da aka bonded a matsayin bonding Layer.
④Hanyar hadawa mai zafi-narke
Polyethylene-acrylate copolymer, vinyl acid-ethylene copolymer da paraffin ana dumama su narke tare, sa'an nan kuma a shafa a kan kayan tushe, nan da nan an haɗa su da sauran kayan haɗin gwiwar sannan a sanyaya.
⑤Multi-Layer extrusion hade hanya
Daban-daban na resin filastik tare da kaddarorin daban-daban ana matse su a cikin ƙirar ta hanyar masu fitar da abubuwa da yawa don samar da fim ɗin da aka haɗa. Wannan tsari baya amfani da adhesives da abubuwan kaushi na halitta tsakanin yadudduka. Fim ɗin ba shi da ƙamshi na musamman kuma ba shi da cutarwa shiga ciki. Ya dace da marufi abinci tare da rayuwa mai tsayi. Misali, tsarin gabaɗaya LLDPE/PP/LLDPE yana da fayyace mai kyau, kuma kauri shine gabaɗaya 50-60.μ m. Idan shiryayye rai ya fi tsayi, wajibi ne a yi amfani da fiye da biyar yadudduka na high shãmaki co-extruded fim, da kuma tsakiyar Layer ne high shãmaki abu PA, PET da EVOH.
