Impilo isoloko igxininiswa
Isihloko esiphindaphindiweyo esinxulumene nokupakishwa kweplastiki yimpilo.Kuyacaca ukuba yonke ipakethe ekhuselayo inceda impilo yomthengi ngokukwahlula ukutya kwiimpembelelo ezahlukeneyo zangaphandle.Kwishishini lesiselo ngokukodwa, ukongezwa kwezinto ezikhuthaza impilo kwiziselo yindlela ekhulayo, ngoko ke ukhuseleko olukhethekileyo lokupakisha luyafuneka kwiziselo ezinjalo, ezifana neziselo zejusi yeziqhamo ezinomthamo wevithamini ephezulu, kunye neziselo zezemidlalo kunye neziselo zokuqina kunye. iziselo ezikhethekileyo zokutya.I-KHS Plasmax, esekelwe eHamburg, eJamani, iphuhlise iteknoloji yePlasmax ukugcina ezi ziselo zitsha kwibhotile ixesha elide.Ngokukodwa, kwinkqubo yoxinzelelo oluphantsi lweplasma, umaleko wesilicon oxide ecocekileyo (oko kukuthi, iglasi) emalunga nama-nanometer angama-50 ifakwe kudonga lwangaphakathiIbhotile ye-PET, ukwenzela ukuba isiselo sikhuseleke kwihlabathi langaphandle, ngoko sinokugcinwa ixesha elide , iivithamini kunye nezongezo aziyi kulahleka.Ngokungafaniyo nokhuphiswano lwetekhnoloji yeebhotile ezininzi, itekhnoloji yePlasmax intsonkothe ngakumbi, kodwa iphumela kwiindleko ezisezantsi kakhulu zemathiriyeli kwibhotile nganye.Inzuzo ephambili yenkqubo yePlasmax kukuba iibhotile zihlaziywa ngokupheleleyo.
Iziselo ezisempilweni ezinamasuntswana amaqhuqhuva yenye intsingiselo kushishino lwesiselo, njengamanzi anamaqhekeza ekhala, kunye nobisi kunye neyogathi enamaqhekeza eziqhamo.Esi siselo asifuni kuphela ukuhambelana kwebhotile, kodwa kunye neteknoloji yokuzalisa enokulinganisa amaqhekeza aqinileyo ngokucocekileyo nangokuchanekileyo.Njengomnye wabakhi bomatshini beengcali ezininzi kule ntsimi, i-Krones, esekelwe e-Neutraubling, eJamani, inikezela nge-trademark ye-Dosaflex i-trademark ye-metering system ekhethekileyo, enokulinganisa i-3mm x 3mm x 3mm ngokuchaneka kwemitha ye-± 0.3% Iincinci ze-lumpy zilinganiswa.
Nangona kunjalo, ngenxa yobomi obunqamlekileyo be-shelf yeziselo zobisi, i-Holland Colors NV, i-Apeldoorn, i-Netherlands, iye yasungula i-additive yayo entsha ye-Holcomer III, enika ukhuseleko lwe-100% kwimitha ye-UV kunye ne-99% yoKhuseleko ekukhanyeni okubonakalayo, ngaloo ndlela ivumela. ukuveliswa kwe-PET monolayer yokupakisha izisombululo zobisi olufakwe kwi-pasteurized.Inzuzo ecacileyo yesi sisombululo kukwakhiwa kwayo kwinqanaba elilodwa, okwenza kube lula ukuphinda kusetyenziswe ukupakishwa kwe-multi-layer ehambelanayo.
Ubulula ngumxholo ongunaphakade
Ngayo yonke isisombululo sokupakisha, ubunzima buhlala bugxininisekile, kwaye kwiminyaka embalwa edlulileyo, iingcamango kunye nezisombululo zokunciphisa ubunzima ziye zavela.Phakathi kwe-1991 kunye ne-2013, ubunzima obubonke bokupakishwa buncitshiswe ngama-25% ngenxa yoyilo olutsha kunye nokunciphisa iindonga.Ngaphandle kokukhula okulindelweyo kokusebenza, ngo-2013 kuphela, i-1 yezigidi zeetoni zeplastiki zagcinwa kwihlabathi jikelele ekupakishweni kokugcina ubunzima.Ukuthatha iibhotile ze-PET njengomzekelo, kungekhona nje ukuncitshiswa kodonga, kodwa uyilo olusezantsi luye lwaphuculwa, kwaye i-spiral design entsha yodwa igcina i-2g yeplastiki ngebhotile.Ukuze kulungiswe umgangatho webhotile, i-Creative Packaging Solutions Ltd., esekelwe e-Balcova-Izmir, eTurkey, iphuhlise inkqubo yayo ye-Mint-Tec, apho, emva kokuba i-preform yenziwe, i-piston ingena kwibhotile ngaphandle kokuchukumisa intamo yebhotile.Umzantsi uzisa imilo efunekayo.
Yenzelwe ukuba iphinde isetyenziswe kwasekuqaleni
Iindlela zokupakisha ezithatha iziselo njengomzekelo zisebenza phantse kuzo zonke ezinye iindawo kwishishini lokutya, apho ukunciphisa ubunzima kuhlala kuqala kuqala.Oku kunjalo ngenxa yokuba ukunciphisa ubunzima kuhambelana nokongiwa kwezinto kunye nokunciphisa iindleko, kodwa ayisiyiyo yodwa.Isizathu, kwaye okona kubaluleke kakhulu, kukuba abenzi bomthetho kunye nabathengi bayanda befuna "ukhuseleko lwezibonelelo", oluhambelana ngokusondeleyo nombono wokupakisha ngokutsha.EJamani, apho phantse zonke iipakethe zasekhaya ziphinda zisetyenziswe, ngaphezulu kwesiqingatha (56%) ziphinda zisetyenziswe endaweni yokuba zitshiswe, ukusuka kwi-3% kwiminyaka engama-20 eyadlulayo.Ngokubhekiselele koku, iibhotile ze-PET zinezinga eliphezulu lokuphinda lisetyenziswe, kunye ne-98% yezinto ezifunyenweyo kwaye zibuyiselwe kumjikelo wemveliso.Oko kukuthi, yonke ibhotile entsha eveliswayo namhlanje iqulethe malunga ne-25% yemathiriyeli esetyenzisiweyo.
Ukusetyenziswa kokupakishwa kwenkunkuma kunokuphuculwa ngakumbi ukuba ukupakishwa kuyilelwe ukuba kuphinde kusetyenziswe kwasekuqaleni.Njengomprosesa we-polyolefin, uGqr Michael Scriba, uMlawuli oLawulayo we-mtm plastiki e-Niedergebra, eJamani, uyazi kakuhle le ngxaki.Ngokombono wakhe, iiplastiki ezihlambulukileyo kufuneka zisetyenziswe naphi na apho kunokwenzeka khona, kunokuba "iphepha-iplastiki" i-composites, kwaye kungekhona i-polyolefins emnyama okanye i-calcium carbonate.Kwakhona, i-PET kufuneka ikhethelwe iibhotile kunetreyi ezotyiweyo ezinzulu.
ibhegi yokupakisha
Iifilimu ziyancipha kwaye zisebenza ngakumbi
Ngesabelo semarike esingaphezulu kwe-40%, ifilimu yeyona nto ixhaphakileyo yokupakishwa kweplastiki esetyenziswa ikakhulu ekutyeni, kodwa kunjalo ikwabandakanya izinto ezinje ngeqamza okanye ifilimu eyolula esetyenziselwa ukukhusela iimpahla.Iimveliso zefilimu eziNcinci zikwabonisa ngokuthe kratya indlela ecacileyo "yokuphuhlisa kwicala lokunciphisa kunye nokusebenza".Nangona iifilimu ezininzi zisetyenziswa ngokuqhelekileyo, ekusebenzeni ukusebenza kweefilimu kunokufumaneka ngokusebenzisa izongezo ezifanelekileyo.Isidingo samacandelo amaninzi kunye nangaphezulu kuye kwaphakama ngokufika kwezinto ezibizwa ngokuba yi "nanolayer" izakhiwo ezinama-33 okanye ngaphezulu.Namhlanje, iifilimu ezi-3 kunye ne-5-layer ziyimveliso eqhelekileyo, kwaye iququzelela ngokukhethekileyo ukusetyenziswa kwe "izinto ezingabizi kuluhlu oluphakathi".
Iifilimu zeBarrier zidla ngokuba ne-7 okanye ngaphezulu.Ngomaleko osebenzayo, iifilimu ezininzi zidla ngokuba nobukhulu obuncinci kunefilimu ezinomaleko omnye.Ngelixa ugcina umsebenzi, ubukhulu bale filimu buya kuncitshiswa ngokunweba.I-Reifenhäuser Blown Films eTroisdorf, eJamani ibonisa iyunithi ye-Evolution Ultra Stretch ezinikele kule njongo.Ukusebenzisa le yunithi yokwelula, iifilimu zengxowa yoxinzelelo ze-diapers zinokuveliswa kwi-50µm endaweni ye-70µm, kunye neefilimu ze-silage zolula ezineempawu ezifanayo zinokuveliswa kwi-19µm endaweni ye-25µm - ubukhulu buncitshiswe nge-30%.
