Inkunkuma yokutya yehlabathi ibangela ilahleko kwezoqoqosho engaphezulu kwe-$400 yeebhiliyoni ngonyaka. Ngaphaya kweendleko zemali, yimbangela ebalulekileyo yotshintsho lwemozulu. Ngokutsho kwe-UN Food and Agriculture Organisation (FAO), malunga ne-13.2% yokutya kulahleka ngaphambi kokuba kufikelelwe kwiindawo zokuthengisa, kwaye enye i-19% ilahleka kwinqanaba labathengi.

Kwi-Interpack 2026, iphulo le-SAVE FOOD ligxininise imfuneko engxamisekileyo yezisombululo zokupakisha ukusuka "kukhuseleko olungasebenziyo" ukuya kulondolozo olusebenzayo. Umqadi we-electronItekhnoloji yokukhanyisa (EB) ivela njengesixhobo esinamandla sokunciphisa inkunkuma kwiinkalo ezimbini: ukuphucula ukusebenza kokupakisha kunye nokuphatha ukutya ngokuthe ngqo. Olu hlaziyo olusekelwe kwisayensi yenyukliya ludala ukhuselo olunemigangatho emibini ekuboleni—ukusuka kwizinto zokupakisha ukuya ekutyeni okungaphakathi.

Kwi-Interpack 2026 eDüsseldorf, eJamani, ingqalelo yayikukudibana kokusebenza kunye nokuzinza kokupakisha. Ukususela kwiipolymers ze-BASF ezisekelwe kwibhayoloji ukuya kwizinto eziphinda zisetyenziswe ngamakhemikhali ze-SABIC, kunye neprojekthi yokupakisha iintsholongwane ye-MATE4MEAT kaFraunhofer ukuya kwiforam ye-SAVE FOOD ethi “Reducing Food Waste”, ishishini lokupakisha lehlabathi likhawuleza ukuya kuqoqosho olujikelezayo.

Sekunjalo iinkampani zokupakisha zijongene nomceli mngeni obalulekileyo: indlela yokunciphisa impembelelo yokusingqongileyo ngelixa zigcina ukusebenza okukhuselekileyo, ixesha elihlala ixesha elide, kunye nokusebenza kakuhle kwemveliso.

Umqadi we-electronItekhnoloji yokukhanyisa imitha (EB), inkqubo yezoshishino eqinisekisiweyo kangangeminyaka emininzi, ivela njengesixhobo esibalulekileyo. Ngokuvumela ukudibanisa okubonakalayo, ukuguqulwa komphezulu, kunye nokucubungula okudibeneyo ngaphandle kwezongezo zeekhemikhali, ukukhanya kwe-EB kuvumela ukupakishwa ukuba:

Ukuncipha ngaphandle kokulahlekelwa ngamandla,

Izinto ezisetyenziswa ngumntu omnye ezisebenza ngendlela efana ne-composite, kunye

Ndibandakanyeka ngokupheleleyo ekwandiseni ixesha lokuphelelwa.

Kwimizi-mveliso efana neyangaphakathi neemoto, izindlu zezixhobo zasekhaya, ukupakishwa kokhathalelo lomntu, kunye nezinto zokudlala, omnye umngeni ophindaphindiweyo "kukuxobuka kwepeyinti emva kokutshiza kwi-PP (polypropylene) okanye kwi-PE substrates." Nangona kukho iinkqubo ezifanayo zangaphambi konyango, ezinye iibhetshi ziyaphumelela kulawulo lomgangatho ngelixa ezinye ziyasilela. Rhoqo, unobangela oyintloko ulandelwa kwinqanaba elinye elibalulekileyo: ukuba umaleko we-primer usetyenziswe ngokufanelekileyo na.

Amanzi e-PP, ii-arhente zonyango ze-PP, ii-PP primers—la magama aqhelekileyo akhomba kwisisombululo esinye: i-chlorinated polypropylene (CPP) resin. Kodwa kutheni injalo? I-resin ye-CPP Isebenza kakuhle ekuphuculeni ukunamathela kwiiplastiki “ezinzima ukuzibopha” ezifana nePP? Iyenza njani ikhonkco elithembekileyo phakathi kwengubo kunye nesiseko?

Kwishishini lokupakisha elinciphisa ubushushu, ifilimu yokunciphisa ubushushu ye-POF (multilayer co-extruded polyolefin) iye yaba yindlela ekhethwayo kuneefilimu zemveli ze-PVC. Ukukhanya kwayo okuphezulu, ukuncitshiswa kwayo okugqwesileyo, ukumelana nokubanda, kunye neempawu ezinobuhlobo nokusingqongileyo zenza ukuba ilungele ukupakisha kunye nokukhusela umphezulu wokutya, iziselo, amayeza, kunye nezicelo zokhathalelo lomntu.

Nangona kunjalo, njengoko iimarike zokupakisha zehlabathi zifuna ukusebenza kakuhle kwemveliso, ukuhambelana okungcono, kunye namazinga aphantsi eziphene, abathengi abasajolisi kuphela kwidatha yokuncipha. Baxhalabile ngakumbi ngendlela iifilimu ezisebenza ngayo kwimigca yokupakisha ekhawulezayo—nokuba ukuncipha kuyalingana, izitywini zigudileyo, kwaye amazinga okuqhekeka ayalawuleka. Kule meko, umqadi we-electron Ukukhanya kwemitha (EB) kuye kwavela njengeteknoloji ebalulekileyo kubavelisi beefilimu zePOF ukuphucula ukuhambelana kwemveliso nokuqinisa ukhuphiswano lwemarike.

Iifilimu zePolyethylene (PE) zezona zinto zisetyenziswa kakhulu ekupakisheni kwihlabathi liphela. Nangona kunjalo, ulwakhiwo lwazo lweemolekyuli oluthe tyaba luthintela iipropati eziphambili ezifana namandla oomatshini, ukumelana nobushushu, kunye nokumelana nokubhoboza. Njengoko ishishini lokupakisha liguqukela kwizisombululo ezilula, ezisebenza kakhulu, nezinokuphinde zisetyenziswe, utshintsho lwendabuko lokuxuba alunakwanela ukuhlangabezana neemfuno ezikhethekileyo.

Itekhnoloji yokukhanyisa i-electron accelerator iye yaba yimbangela yokuguqula iifilimu ze-PE ukusuka "kwizinto eziqhelekileyo" ukuya "kwizinto ezisebenzayo." Ngokudala inethiwekhi edibeneyo enamacala amathathu phakathi kweetyathanga zepolymer, imiqadi ye-elektroni ukuphucula kakhulu iipropati zefilimu ye-PE—ukuphucula ukumelana nokubhoboza, ukumelana nobushushu, ukufana kokuncitshiswa, kunye nokuphinda kusetyenziswe—ngaphandle kokutshintsha indlela esisiseko yokwenza.

Iifilimu ezidityaniswe ngobuninzi kufuneka zilinganisele ukuvalwa kobushushu, iimpawu zokuthintela, amandla, kunye nenkangeleko—ngokufuthi ngenxa yempawu enye okanye ezingaphezulu. Iifilimu zoshishino ezinzima, kwelinye icala, zifuna ukumelana nokubhoboza, ukumelana nokukrazula, kunye nokuqina kwemozulu, nto leyo enyanzelisa ukutshintshiselana okubuthathaka phakathi kobukhulu kunye neendleko. Njengoko iimfuno zabathengi zitshintsha ziye "kwincinci," "ziqinileyo," kwaye "ziphinda zisetyenziswe," ukulungiswa kwezinto zemveli akusafikeleli kuphawu.

Ukukhanya kwemisebe ye-electron Ukudibanisa macala omabini kunika isisombululo kule "nxantathu ingenakwenzeka" kwinqanaba leemolekyuli. Le teknoloji ayitshintshi izinto ezisisiseko kodwa endaweni yoko isebenzisa ii-electron ezinamandla aphezulu "ukudityaniswa" kweenethiwekhi ezinemilinganiselo emithathu phakathi kweetyathanga zepolymer. Le nkqubo yandisa iziphumo zentsebenziswano zezakhiwo ezineengqimba ezininzi kwaye iphucula kakhulu imida yokusebenza kweefilimu ezinzima.

Njengoko imfuno yokutya okulungele ukutyiwa kunye nokutya okulungisiweyo iqhubeka nokukhula, ukubulala iintsholongwane kubushushu obuphezulu kuye kwaba yindlela ebalulekileyo yokuqinisekisa ukhuseleko lokutya kunye nokwandisa ixesha lokuphelelwa. Ukubulala iintsholongwane (85-95°C) kusetyenziswa kakhulu kukutya okune-asidi ephantsi njengobisi, iijusi, kunye nebhiya, ngelixa ukubulala iintsholongwane kubushushu obuphezulu, okunoxinzelelo oluphezulu (121-135°C) kubalulekile kwinyama, iimveliso zesoya, kunye nokutya okuneproteni ephezulu okufuna ukungabi nantsholongwane kurhwebo. Olu nyango lobushushu lususa ngempumelelo iintsholongwane kodwa lukwabeka iimfuno ezibalulekileyo kwiifilimu zokupakisha - kufuneka zigcine ukuthembeka kwesakhiwo, ukuthembeka kokutywina, kunye nozinzo olulinganayo phantsi kobushushu obuphezulu.

Nangona kunjalo, iifilimu ze-thermoplastic zemveli zinemida yendalo ekumelaneni nobushushu. Umzekelo, i-polyethylene (PE) ine-Vicat softening point ephakathi kwe-90-110°C kwaye iqala ukuthamba kumaqondo obushushu angaphezu kwe-85°C. Nangona i-polypropylene (PP) inokumelana namanzi abilayo, isajongene nemingcipheko yokuguquguquka engaphezulu kwe-121°C. Itekhnoloji yokudibanisa imisebe ye-electroniye yavela njengotshintsho olukhulu, yandisa ukumelana nobushushu kwinqanaba leemolekyuli kwaye yajongana nale mingeni ngempumelelo.

Kwimigca yokuvelisa iipakethe ezikhawulezayo, umzuzwana ngamnye ubalulekile xa kufikwa ekusebenzeni kwefilimu. Ukutshintshatshintsha kwe-±5% kwisantya sokuncipha kweefilimu ezinciphileyo kunokukhokelela kwiilebheli ezingalungelelananga kakuhle, ukupakisha okukhululekileyo, kwaye ekugqibeleni, ukungasebenzi kakuhle kwemveliso. Ukuba umaleko wesitywino ulahlekelwa kukuqina kobushushu ngenxa yongcoliseko yioyile okanye uthuli, kunokubangela ukuvuza, ukungaphumeleli kweepakethe, kunye nexesha lokungasebenzi kwemveliso. Kumashishini afana nokutya kunye nokhathalelo lwempilo, apho ukuthembeka kweepakethe kungaxoxiswana khona, ukufikelela ekusebenzeni "okungaguquguqukiyo" kubaluleke kakhulu kunokuba neempawu "eziphambili".

Izixhobo zemveli ezisetyenziswa kwiifilimu ezinciphileyo kunye neengqimba zesitywina zihlala zijongene nemida ngenxa yokunyakaza kobushushu beetsheyini zazo zemolekyuli. Utshintsho kubushushu, ixesha lokugcina, kunye nesantya sokucubungula kunokukhokelela kwimiba efana nokushukuma kwesantya sokuncitshiswa, ukuncipha kokuthe tyaba, kunye namandla okutywina kobushushu angaguqukiyo. Itekhnoloji yokudibanisa imisebe ye-electronitshintshe umdlalo ngokuyitshixa i-microstructure yeefilimu kwinqanaba leemolekyuli, nto leyo eyenza ukusebenza okuqhubekekayo kube yinyani.

Ukususela nge-12 ka-Agasti 2026, uMthetho we-European Union wokuPakisha nokuPakisha iNkunkuma (PPWR) uza kuqaliswa ngokupheleleyo, nto leyo efuna ukuba zonke iipakeji ezibekwe kwimarike ye-EU ziphinde zisetyenziswe. Ngaloo mini, imida emitsha ye-PFAS (i-perfluoroalkyl kunye nezinto ze-polyfluoroalkyl) kwiipakeji zokudibanisa ukutya iya kuqala ukusebenza, apho i-PFAS nganye ingadluli kwi-25 ppb kwaye uxinano lulonke lungadluli kwi-250 ppb. Ukongeza, uxinano lulonke lwe-lead, i-cadmium, i-mercury, kunye ne-hexavalent chromium luya kulinganiselwa kwi-100 mg/kg. Okwangoku, umgangatho we-GB 4806.10-2025 waseTshayina uza kuqala ukusebenza ngoSeptemba 2026, unciphise kakhulu umda wokufuduka kwe-bisphenol A ukusuka kwi-0.6 mg/kg ukuya kwi-0.05 mg/kg. UMthetho we-EU woNxibelelwano lokutya wePlastics (EU) 2026/245, oqala ukusebenza ngoFebruwari 2026, uya kunyanzelisa imida yokufuduka eqinileyo kwizinto ezintandathu ezintsha.

Njengoko iingcamango "zokupakisha okucocekileyo" kunye "noqoqosho olujikelezayo" zitshintsha ukusuka kwimizamo yoshishino ukuya kwiimfuno ezinyanzelekileyo, umqadi we-electronItekhnoloji yokukhanyisa (EB) iyabonakala. Ngeempawu zayo "ezingenazo izongezo, ezingenantsalela, eziluhlaza, nezinekhabhoni ephantsi", itekhnoloji ye-EB ibonelela abavelisi bokupakisha ukutya ngesisombululo esihambelana ngokugqibeleleyo neendlela zokulawula zehlabathi kukhuseleko kunye nokuzinza.

Kwishishini lokupakisha, abathengi banemfuno ezahlukeneyo nezikhethekileyo zokusebenza kwefilimu. Ezinye zifuna iipropati zokuthintela eziphezulu kakhulu ukuze zandise ixesha lokuhlala eshelufini, ngelixa ezinye zifuna ukuguquguquka okungaqhelekanga ukuze zilungelelanise iimilo zokupakisha ezingaqhelekanga, okanye ukukwazi ukumelana neenkqubo zokubulala iintsholongwane ezishushu kakhulu. Iindlela zemveli zokuguqula iifilimu, ezinje ngokuxuba, ukukhupha iileya ezininzi kunye nokudibanisa iikhemikhali, zihlala zithintelwa ziifomyula ezizinzileyo, iifestile zenkqubo ezimxinwa, kunye nemijikelo yokulungisa emide, okwenza kube nzima ukuphendula ngokukhawuleza nangokufanelekileyo kwimfuno ekhulayo yezisombululo ezenzelwe wena.

Umqadi we-electronItekhnoloji yokukhanyisa (i-e-beam) inika indlela entsha nesebenza kakuhle kakhulu yokufezekisa "ukwenziwa ngokwezifiso" kweempawu zefilimu. Isebenza "njengenkqubo yokusebenza" echanekileyo, evumela abavelisi ukuba balungise isakhiwo sefilimu ngaphandle kokutshintsha indlela esisiseko yokwenza. Ngokulawula ngononophelo iiparameter ezifana namandla, idosi, kunye nendlela yokuskena, ukukhanyiswa kwemitha ye-e-beaminika umgangatho ophezulu wokuguquguquka, okuvumela ukutshintsha ukusuka kwimigangatho ukuya ekusebenzeni ngokwezifiso ngokuchanekileyo okugqwesileyo.
