Isondlo sezemidlalo ligama eliqhelekileyo, eliquka iimveliso ezininzi ezahlukeneyo ukusuka kwiprotheyini engumgubo ukuya kwizinti zamandla kunye neemveliso zempilo. Ngokwesiko, umgubo weprotheyini kunye neemveliso zempilo zipakishwe kwimibhobho yeplastiki. Kutshanje, inani leemveliso zezondlo zezemidlalo ezinezisombululo zokupakisha ezithambileyo zonyukile. Namhlanje, isondlo sezemidlalo sinezisombululo ezahlukeneyo zokupakisha.
Isikhwama sokupakisha esineprotheyini sibizwa ngokuba yi-flexible packaging, esebenzisa kakhulu izinto ezithambileyo, ezifana nephepha, ifilimu, i-aluminium foil okanye ifilimu enesinyithi. Ngaba wakha wazibuza ukuba yintoni ukupakishwa okuguquguqukayo kwengxowa yeprotheyini eyenziwe? Kutheni le nto ipakethe nganye eguquguqukayo inokuprintwa ngeepatheni ezinemibala ukutsala ukuba uthenge? Emva koko, eli nqaku liza kuhlalutya isakhiwo sokupakishwa okuthambileyo.
Izinto ezilungileyo zokupakisha eziguquguqukayo
Ukupakishwa okuguquguqukayo kuyaqhubeka ukubonakala kubomi babantu. Logama nje uhamba kwivenkile ethengisa izinto ezilula, unokubona ukupakishwa okuguquguqukayo kunye neepatheni ezahlukeneyo kunye nemibala kwiishelufu. Ukupakishwa okuguquguqukayo kuneengenelo ezininzi, yiyo loo nto kunokusetyenziswa kumashishini amaninzi ahlukeneyo, afana neshishini lokutya, ishishini lombane, ishishini lobuhle bezonyango, amashishini ekhemikhali yemihla ngemihla kunye nemveliso yemveliso.
1. Iyakwazi ukuhlangabezana neemfuno zokhuseleko ezihlukeneyo zempahla kunye nokuphucula ubomi beshelufu yempahla.
Ukupakishwa okuguquguqukayo kunokuqulunqwa ngezinto ezahlukeneyo, nganye ineempawu zayo zokukhusela imveliso kunye nokuphucula ixesha elide. Ngokwesiqhelo, inokufikelela kwiimfuno zokuthintela umphunga wamanzi, igesi, igrisi, isinyibilikisi esineoyile, njl. inetyhefu kwaye ayingcolisi.
2. Inkqubo elula, kulula ukuyisebenzisa kunye nokusetyenziswa.
Xa usenza ukupakishwa okuguquguqukayo, inani elikhulu lokupakisha okuguquguqukayo linokuveliswa nje ngokuba umatshini onomgangatho omhle uthengwa, kwaye iteknoloji ilawulwa kakuhle. Kubathengi, ukupakishwa okuguquguqukayo kukulungele ukusebenza kwaye kulula ukuyivula kunye nokutya.
3. Ngokukodwa kufanelekile ukuthengisa, kunye nesibheno esinamandla semveliso.
Ukupakishwa okuguquguqukayo kunokuthathwa njengeyona ndlela yokupakisha efikelelekayo ngenxa yolwakhiwo olukhaphukhaphu kunye nokuziva kwesandla esikhululekile. Isici sokuprintwa kombala kwipakethe kwenza kube lula ukuba abavelisi baveze ulwazi lwemveliso kunye neempawu ngendlela epheleleyo, ukutsala abathengi ukuba bathenge le mveliso.
4. Iindleko zokupakisha eziphantsi kunye neendleko zokuhamba
Ekubeni ininzi yokupakishwa okuguquguqukayo yenziwe ngefilimu, izinto zokupakisha zithatha indawo encinci, ukuthutha kulungeleka kakhulu, kwaye iindleko ezipheleleyo ziyancipha kakhulu xa kuthelekiswa neendleko zokupakisha eziqinileyo.
Iimpawu ze-flexible package substrates
Iphakheji nganye eguquguqukayo idla ngokuprintwa ngeepateni ezininzi ezahlukeneyo kunye nemibala ukutsala abathengi ukuba bathenge imveliso. Ushicilelo lwepakethe eguquguqukayo lwahlulwe ngeendlela ezintathu, ezizezi, ushicilelo olungaphezulu, ushicilelo lwangaphakathi ngaphandle kokudibanisa kunye noshicilelo lwangaphakathi. Ukuprintwa komphezulu kuthetha ukuba i-inki ishicilelwe kumphezulu ongaphandle wepakethe. Ukuprintwa kwangaphakathi akudityaniswanga, oku kuthetha ukuba iphethini ishicilelwe kwicala langaphakathi lepakethe, enokuthi idibane nokupakisha. Umaleko wesiseko wokupakishwa kwezinto ezidibeneyo kunye nokushicilela ukwahlula. Ii-substrates ezahlukeneyo zokushicilela zineempawu zazo ezizodwa kwaye zifanelekile kwiindidi ezahlukeneyo zokupakisha eziguquguqukayo.
1. BOPP
Kweyona substrate yokupakisha eguquguqukayo ixhaphakileyo, akufuneki kubekho mingxunya ilungileyo ngexesha loshicilelo, kungenjalo iya kuchaphazela icandelo lekhusi elingekho nzulu. Ingqwalasela eyodwa kufuneka ihlawulwe ekucuthekeni kobushushu, ukucinezeleka komphezulu kunye nokuguda komphezulu, uxinzelelo lokushicilela kufuneka lubephakathi, kwaye ubushushu bokoma bube ngaphantsi kwama-80 °C.
2. BOPET
Ngenxa yokuba ifilimu yePET idla ngokuba mncinane, ifuna uxinezeleko olukhulu ukuze yenziwe ngexesha lokushicilela. Kwicala le-inki, kungcono ukusebenzisa i-inki yobuchwephesha, kwaye umxholo oprintwe nge-inki jikelele kulula ukususwa. Iworkshop inokugcina ukufuma okuthile ngexesha lokushicilela, okunceda ukunyamezela amaqondo obushushu aphezulu.
3. BOPA
Eyona nto inkulu kukuba kulula ukufunxa ukufuma kunye nokukhubazeka, ngoko ke nikela ingqalelo ekhethekileyo kwesi sitshixo xa uprinta. Ngenxa yokuba kulula ukufunxa ukufuma kunye nokukhubazeka, kufuneka isetyenziswe ngokukhawuleza emva kokukhupha, kwaye ifilimu eseleyo kufuneka ivalwe kwaye ingabonakali ngokukhawuleza. Ifilim yeBOPA eprintiweyo kufuneka idluliselwe ngokukhawuleza kwinkqubo elandelayo yokulungiswa komdibaniso. Ukuba ayinakuxutywa ngokukhawuleza, kufuneka ivalwe kwaye ifakwe, kwaye ixesha lokugcina alikho ngaphezu kweeyure ezingama-24.
4. CPP, CPE
Kwiifilimu ezingabonakaliyo ze-PP kunye ne-PE, ukunyanzeliswa kokushicilela kuncinci, kwaye ubunzima bokushicilela bukhulu kakhulu. Xa uyila iphethini, isixa sokuguqulwa kwepateni kufuneka siqwalaselwe ngokupheleleyo.
Ubume bokupakishwa okuguquguqukayo
Njengoko igama libonisa, ukupakishwa okuguquguqukayo kwenziwa ngamaleko ahlukeneyo ezinto. Ukusuka kwindawo yokujonga i-architecture elula, ukupakishwa okuguquguqukayo kunokwahlulwa ngokwamacandelo amathathu. Izinto ezingaphandle zomaleko zihlala zi-PET, NY (PA), i-OPP okanye iphepha, i-middle layer material yi-Al, VMPT, PET okanye i-NY (PA), kunye ne-inner layer material yi-PE, CPP okanye i-VMCPP. Faka i-adhesive phakathi kwendawo yangaphandle, i-middle layer kunye ne-inner layer ukuze udibanise iileya ezintathu zezinto omnye komnye.
Kubomi bemihla ngemihla, izinto ezininzi zifuna izinto ezincamathelayo ukuze zihlangane, kodwa asifane siqonde ukubakho kwezi zinto zincamathelayo. Njengokupakisha okuguquguqukayo, i-adhesives isetyenziselwa ukudibanisa imigangatho eyahlukeneyo yomhlaba. Thatha umzi-mveliso weGarment njengomzekelo, bayasazi isakhiwo sokupakishwa okuguquguqukayo kunye namanqanaba ahlukeneyo angcono. Umphezulu wokupakishwa oguquguqukayo udinga iipateni ezityebileyo kunye nemibala ukutsala abathengi ukuba bathenge. Ngexesha lenkqubo yoshicilelo, umzi-mveliso wobugcisa bemibala uya kuqala uprinte ipateni kumaleko wefilimu, emva koko usebenzise i-adhesive ukudibanisa ifilimu enepateni kunye nezinye iileya zangaphezulu. Iglu. I-adhesive yokupakisha eguquguqukayo (i-PUA) enikezelwa yi-Coating Precision Materials inefuthe elihle kakhulu lokudibanisa kwiifilimu ezahlukeneyo, kwaye ineenzuzo zokungachaphazeli umgangatho wokushicilela we-inki, amandla aphezulu okubambisana kokuqala, ukumelana nobushushu, ukuchasana nokuguga, njl.
