Kukho iintlobo ezininzi zeengxowa zokupakisha ukutya ezisetyenziselwa ukupakishwa kokutya, kwaye zinemisebenzi yazo eyahlukileyo kunye neempawu.Namhlanje siza kuxoxa ngolwazi lwengxowa yokutya edla ngokusetyenziswa kwireferensi yakho.Ngoko yintoni ingxowa yokupakisha ukutya?Iingxowa zokupakisha ukutya ngokubanzi zibhekisa kwiiplastiki zeshiti ezinobunzima obungaphantsi kwe-0.25mm njengeefilimu, kwaye ukupakishwa okuguquguqukayo okwenziwe ngeefilimu zeplastiki kusetyenziswa kakhulu kushishino lokutya.Kukho iindidi ngeendidi zeengxowa zokupakisha ukutya.Ziyabonakala, ziguquguqukayo, zinokumelana kakuhle kwamanzi, ukuxhathisa ukufuma kunye neempawu zokuthintela igesi, amandla afanelekileyo omatshini, iipropati ezizinzileyo zeekhemikhali, ukuxhathisa kweoli, ukuprintwa ngokulula, kwaye kunokutywinwa ukushisa ukwenza iingxowa.Ngaphezu koko, ukupakishwa kokutya okuguquguqukayo okuqhelekileyo kusetyenziswa iileyibhile ezimbini okanye ngaphezulu zeefilimu ezahlukeneyo, ezinokwahlulwa ngokubanzi zibe ngumaleko ongaphandle, umaleko ophakathi kunye nomaleko wangaphakathi ngokwendawo.
Zeziphi iimfuneko zokusebenza komaleko ngamnye weefilimu zokupakisha ezisetyenziswa ngokuqhelekileyo zokutya?Okokuqala, ifilim yangaphandle iyaprintwa ngokubanzi, ayiqhawuki, kwaye ayinyangeki ngokuphakathi.Izinto ezisetyenziswa ngokuqhelekileyo ziyi-OPA, i-PET, i-OPP, ifilimu edibeneyo, njl.Izinto ezisetyenziswa ngokuqhelekileyo ziquka i-BOPA, i-PVDC, i-EVOH, i-PVA, i-PEN, i-MXD6, i-VMPT, i-AL, njl.Izinto ezisetyenziswa ngokuqhelekileyo ziyi-CPP, i-PE, njl. Ukongezelela, ezinye izinto zinomsebenzi odibeneyo woluhlu lwangaphandle kunye nomgangatho ophakathi.Umzekelo, i-BOPA ingasetyenziswa njengomaleko wangaphandle kunye nomgangatho wangaphakathi, kwaye ingasetyenziswa njengomaleko ophakathi ukudlala umqobo othile kunye nokukhuselwa ngokomzimba.
Iimpawu zefilimu zokupakisha ezisetyenziswa ngokuqhelekileyo, ukuthetha ngokubanzi, izinto zangaphandle kufuneka zibe nokumelana nokukrazula, ukuxhathisa kwe-UV, ukumelana nokukhanya, ukuchasana kwe-oyile, ukumelana ne-organic, ukumelana nokubanda, ukumelana noxinzelelo lokuqhekeka, ukuprintwa, ukuzinza kobushushu, ivumba eliphantsi, eliphantsi. Uluhlu lweempawu ezifana nevumba, i-non-toxicity, i-luster, i-transparency, shading, njl.;Isixhobo somaleko esiphakathi ngokubanzi sinokumelana nempembelelo, ukumelana noxinzelelo, ukuxhathisa kokugqobhoza, ukuxhathisa ukufuma, ukuxhathisa kwerhasi, ukugcinwa kwevumba elimnandi, ukumelana nokukhanya, ukumelana ne-oyile, ukuxhathisa kwe-organic, ukumelana nobushushu kunye nokumelana nokubanda., ukuxhathisa ukuxhatshazwa kwengcinezelo, amandla adibeneyo aphindwe kabini, iphunga eliphantsi, iphunga eliphantsi, elingenabuthi, elingenabuthi, elingenakukhanya kunye nezinye iimpawu;ke impahla yangaphakathi umaleko, ukongeza kwezinye iimpawu eziqhelekileyo kunye umaleko wangaphandle kunye umaleko ophakathi, nayo ineempawu zayo ezizodwa, kufuneka Ukugcinwa Nevumba, adsorption eliphantsi kunye nokungangeni.Uphuhliso lwangoku lweengxowa zokupakisha ukutya ngolu hlobo lulandelayo: 1. Iingxowa zokupakisha ukutya ezenziwe ngezinto ezikhusela indalo.2. Ukuze kuncitshiswe iindleko kunye nokugcina izibonelelo, iingxowa zokupakisha ukutya ziphuhlisa ekunciphiseni.3. Iingxowa zokupakisha ukutya ziphuhlisa ngokubhekiselele ekusebenzeni okukhethekileyo.Izinto ezidityanisiweyo eziphezulu-zithintelo ziya kuqhubeka ukwandisa umthamo wemarike.Iifilimu ezinomqobo ophezulu kunye neenzuzo zokucutshungulwa okulula, i-oksijini eyomeleleyo kunye neempawu zokuthintela umphunga wamanzi, kunye nobomi obuphuculweyo beshelufu buya kuba yinto ehamba phambili yokupakisha ukutya okuguquguqukayo kwivenkile enkulu kwixesha elizayo.
