Kukho iintlobo ezininzi zeengxowa zokupakisha ukutya ezisetyenziselwa ukupakishwa kokutya, kwaye zinemisebenzi yazo eyahlukileyo kunye neempawu.Namhlanje siza kuxoxa ngolwazi oluqhelekileyo olusetyenziswayo lweengxowa zokupakisha ukutya kwireferensi yakho.Ngoko yintoni ingxowa yokupakisha ukutya?Iingxowa zokupakisha ukutya ngokubanzi zibhekisa kwiiplastiki ezifana nephepha ezinobunzima obungaphantsi kwe-0.25 mm njengeefilimu, kwaye ukupakishwa okuguquguqukayo okwenziwe ngeefilimu zeplastiki kusetyenziswa kakhulu kushishino lokutya.Kukho iindidi ngeendidi zeengxowa zokupakisha ukutya.Ziyabonakala, ziguquguqukayo, zinokumelana kakuhle kwamanzi, ukuxhathisa umswakama kunye neempawu zokuthintela igesi, amandla afanelekileyo omatshini, iipropati ezizinzileyo zeekhemikhali, ukuxhathisa kweoli, kulula ukuprinta kakuhle, kwaye kunokutywinwa ukushisa kwiingxowa.Ngaphaya koko, ukupakishwa okuqhelekileyo kokutya okusetyenziswa ngokuqhelekileyo kudla ngokwenziwa ngamacandelo amabini okanye ngaphezulu eefilimu ezahlukeneyo, ezinokwahlulwa ngokubanzi ngokwamaleko angaphandle, umaleko ophakathi kunye nomaleko wangaphakathi ngokwezikhundla zabo.
Zeziphi iimfuneko zokusebenza komaleko ngamnye weefilimu zokupakisha ukutya eziguquguqukayo eziqhelekileyo?Okokuqala, ifilim yangaphandle iyaprintwa ngokubanzi, ayiqhawuki, kwaye iyaxhathisa kumajelo eendaba.Izinto ezisetyenziswa ngokuqhelekileyo ziquka i-OPA, i-PET, i-OPP, kunye neefilimu ezigqunyiweyo.Ifilimu yomaleko ophakathi ngokubanzi inemisebenzi efana nesithintelo, ukukhanya okukhanyayo, kunye nokhuseleko lomzimba.Izinto ezisetyenziswa ngokuqhelekileyo ziquka i-BOPA, i-PVDC, i-EVOH, i-PVA, i-PEN, i-MXD6, i-VMPT, i-AL, njl. Emva koko kukho ifilimu yangaphakathi, ngokuqhelekileyo inemisebenzi yomqobo, ukutywinwa, kunye ne-anti-media.Izinto ezisetyenziswa ngokuqhelekileyo ziyi-CPP, i-PE, njl njl. Ukongeza, ezinye izinto zinamaleko angaphandle kunye nomgangatho ophakathi.Umzekelo, i-BOPA ingasetyenziswa njengomaleko wangaphandle wokushicilela, kwaye ingasetyenziswa njengomaleko ophakathi ukuze idlale indima ethile yesithintelo kunye nokukhuselwa komzimba.
Iimpawu zefilimu zokupakisha ezisetyenziswa ngokuqhelekileyo, ngokuqhelekileyo, izinto eziphathekayo zangaphandle kufuneka zibe nokuxhathisa ukukrazula, ukuxhathisa i-puncture, ukukhuselwa kwe-UV, ukuchasana nokukhanya, ukuchasana kwe-oyile, ukuxhathisa izinto eziphilayo, ukuchasana nokushisa kunye nokubanda, ukumelana noxinzelelo, ukuprintwa, ukuzinza kobushushu, iphunga eliphantsi, eliphantsi Elingenavumba, elingenalo ityhefu, licwebezelayo, elicacileyo, i-shading kunye noluhlu lweempawu;imaleko ephakathi kufuneka ngokubanzi ibe nokumelana nempembelelo, ukumelana noxinzelelo, ukuxhathisa kokugqobhoza, ukumelana nokufuma, ukuxhathisa kwerhasi, ukugcinwa kwevumba elimnandi, ukumelana nokukhanya, ukumelana neoyile, ukuxhathisa izinto eziphilayo, ukumelana nobushushu kunye nokubanda, ukumelana nokuqhekeka koxinzelelo, amandla adibeneyo anamacala amabini, incasa ephantsi, ivumba eliphantsi, i-non-toxic, transparent, light-proof kunye nezinye iimpawu;ke impahla yangaphakathi umaleko, ukongeza kwezinye iipropati eziqhelekileyo kunye umaleko wangaphandle kunye umaleko ophakathi, nayo ineempawu zayo ezizodwa, ekufuneka ukuba Ukugcinwa Nevumba, adsorption eliphantsi kunye neempawu anti-seepage.Uphuhliso lwangoku lweengxowa zokupakisha ukutya ngolu hlobo lulandelayo:
1. Iingxowa zokupakisha ukutya ezenziwe ngezinto ezikhusela indalo.
2. Ukuze kuncitshiswe iindleko kwaye kugcinwe izibonelelo, iingxowa zokupakisha ukutya ziba zincinci.
3. Iingxowa zokupakisha ukutya ziphuhlisa kwicala lemisebenzi ekhethekileyo.Izinto ezidityanisiweyo eziphezulu-zithintelo ziya kuqhubeka ukwandisa umthamo wemarike.Kwixesha elizayo, iifilimu ezinezithintelo eziphezulu kunye neenzuzo zokucutshungulwa okulula, i-oksijini eyomeleleyo kunye nokusebenza komqobo womphunga wamanzi, kunye nobomi obuphuculweyo beshelufu iya kuba yinto ephambili yokupakishwa kokutya okuguquguqukayo kwiivenkile ezinkulu kwixesha elizayo.
