Cov khoom noj pov tseg thoob ntiaj teb ua rau muaj kev poob nyiaj txiag ntau dua $ 400 billion txhua xyoo. Tsis tas li ntawm tus nqi nyiaj txiag, nws yog ib qho tseem ceeb uas ua rau muaj kev hloov pauv huab cua. Raws li UN Food and Agriculture Organization (FAO), kwv yees li 13.2% ntawm cov khoom noj ploj ua ntej mus txog rau kev muag khoom, thiab lwm 19% raug pov tseg ntawm cov neeg siv khoom.

Ntawm Interpack 2026, qhov kev pib ua SAVE FOOD tau hais txog qhov xav tau ceev ceev rau cov kev daws teeb meem ntim khoom kom txav mus los ntawm "kev tiv thaiv tsis siv neeg" mus rau kev khaws cia nquag. Lub teeb hluav taws xob(EB) thev naus laus zis irradiation tab tom tshwm sim los ua ib qho cuab yeej muaj zog los txo cov khib nyiab ntawm ob sab: txhim kho kev ua haujlwm ntim khoom thiab kho cov khoom noj ncaj qha. Qhov kev tsim kho tshiab raws li nuclear-science no tsim kev tiv thaiv ob txheej tiv thaiv kev puas tsuaj - los ntawm cov khoom ntim mus rau cov khoom noj sab hauv.

Ntawm Interpack 2026 hauv Düsseldorf, Lub Tebchaws Yelemees, qhov kev tsom mus rau qhov kev sib tshuam ntawm kev ua haujlwm thiab kev ruaj khov hauv kev ntim khoom. Txij li BASF cov polymers bio-based mus rau SABIC cov khoom siv rov ua dua tshiab, thiab los ntawm Fraunhofer's MATE4MEAT antimicrobial packaging project mus rau SAVE FOOD initiative's "Reducing Food Waste", kev lag luam ntim khoom thoob ntiaj teb tab tom nrawm nrawm mus rau kev lag luam ncig.

Txawm li cas los xij, cov tuam txhab ntim khoom ntsib teeb meem tseem ceeb: yuav ua li cas kom txo tau qhov cuam tshuam rau ib puag ncig thaum tseem tswj tau kev ua haujlwm tiv thaiv, lub sijhawm khaws cia, thiab kev ua haujlwm zoo.

Lub teeb hluav taws xob(EB) irradiation thev naus laus zis, ib qho txheej txheem kev lag luam uas tau ua pov thawj rau ntau xyoo lawm, tab tom tshwm sim ua ib qho tseem ceeb. Los ntawm kev ua kom muaj kev sib txuas ntawm lub cev, kev hloov kho qhov chaw, thiab kev ua tiav kev sib xyaw ua ke yam tsis muaj cov tshuaj ntxiv, EB irradiation tso cai rau kev ntim khoom kom ua tau:

Nyias nyias dua yam tsis poob zog,

Ib yam khoom siv uas muaj kev ua tau zoo zoo li sib xyaws, thiab

Koom tes nquag hauv kev txuas lub neej txee.

Hauv cov lag luam xws li sab hauv thiab sab nraud ntawm lub tsheb, cov khoom siv hauv tsev, cov khoom ntim khoom siv rau tus kheej, thiab cov khoom ua si, ib qho teeb meem uas rov tshwm sim yog "xim pleev xim tev tawm tom qab txau rau ntawm PP (polypropylene) lossis PE substrates." Txawm tias muaj cov txheej txheem kho ua ntej zoo ib yam, qee cov khoom dhau qhov kev tswj xyuas zoo thaum lwm cov tsis ua tiav. Feem ntau, qhov ua rau muaj teeb meem yog ib kauj ruam tseem ceeb: seb cov txheej primer puas tau siv kom raug.

Cov dej PP, cov neeg sawv cev kho PP, cov tshuaj pleev PP—cov lus paub zoo no txhua tus taw tes rau tib qho kev daws teeb meem: chlorinated polypropylene (CPP) resin. Tab sis vim li cas CPP resin zoo heev rau kev txhim kho kev nplaum rau ntawm cov yas "nyuaj rau kev sib txuas" xws li PP? Nws ua li cas thiaj tsim tau kev sib txuas ruaj khov ntawm cov txheej thiab cov khoom siv?

Hauv kev lag luam ntim khoom cua sov, POF (multilayer co-extruded polyolefin) shrink zaj duab xis tau dhau los ua lwm txoj hauv kev zoo dua li cov zaj duab xis PVC ib txwm muaj. Nws cov pob tshab siab, shrinkage zoo heev, tiv taus txias, thiab cov yam ntxwv zoo rau ib puag ncig ua rau nws zoo tagnrho rau kev ntim khoom thiab kev tiv thaiv qhov chaw hauv cov khoom noj, dej haus, tshuaj, thiab kev siv rau tus kheej.

Txawm li cas los xij, vim tias kev lag luam ntim khoom thoob ntiaj teb xav tau kev ua haujlwm zoo dua, kev sib xws zoo dua, thiab qis dua qhov tsis zoo, cov neeg yuav khoom tsis tsuas yog tsom mus rau cov ntaub ntawv shrinkage xwb. Lawv txhawj xeeb ntxiv txog seb cov yeeb yaj kiab ua haujlwm li cas ntawm cov kab ntim khoom ceev ceev - seb shrinkage puas sib npaug, cov foob du, thiab cov nqi tawg tuaj yeem tswj tau. Hauv qhov xwm txheej no, lub teeb hluav taws xob (EB) irradiation tau tshwm sim los ua ib qho thev naus laus zis tseem ceeb rau cov tuam txhab tsim zaj duab xis POF los txhim kho cov khoom lag luam sib xws thiab txhawb kev sib tw ua lag luam.

Cov yeeb yaj kiab Polyethylene (PE) yog cov khoom siv ntim khoom siv dav tshaj plaws thoob ntiaj teb. Txawm li cas los xij, lawv cov qauv molecular linear txwv cov khoom tseem ceeb xws li lub zog kho tshuab, tiv taus cua sov, thiab tiv taus qhov tho. Raws li kev lag luam ntim khoom hloov pauv mus rau qhov sib dua, ua haujlwm siab, thiab cov kev daws teeb meem rov ua dua tshiab, kev hloov pauv sib xyaw ua ke tsis txaus kom ua tau raws li cov kev xav tau tshwj xeeb.

Kev siv tshuab hluav taws xob ua kom nrawm dua tau dhau los ua lub zog tsav tsheb tom qab hloov cov yeeb yaj kiab PE los ntawm "cov ntaub ntawv dav dav" mus rau "cov ntaub ntawv ua haujlwm." Los ntawm kev tsim cov network sib txuas peb-seem ntawm cov saw polymer, cov teeb hluav taws xob ua kom cov khoom ntawm zaj duab xis PE zoo dua qub—txhim kho kev tiv thaiv kev tawg, kev tiv thaiv cua sov, kev sib npaug ntawm kev ntsws, thiab kev siv rov qab tau—yam tsis hloov cov qauv hauv paus.

Cov yeeb yaj kiab uas muaj ntau txheej sib koom ua ke yuav tsum sib npaug rau kev kaw cua sov, cov yam ntxwv ntawm kev thaiv, lub zog, thiab qhov tsos - feem ntau ntawm tus nqi ntawm ib lossis ntau yam ntxwv. Cov yeeb yaj kiab kev lag luam hnyav, ntawm qhov tod tes, xav tau kev tiv thaiv kev tho, kev tiv thaiv kev tsim kua muag, thiab kev ruaj khov ntawm huab cua, yuam kom muaj kev sib pauv ntawm qhov tuab thiab tus nqi. Raws li cov neeg siv khoom xav tau hloov mus rau "nyias dua," "muaj zog dua," thiab "rov ua dua tshiab," kev hloov kho cov khoom siv ib txwm tsis ua tau raws li qhov ntsuas.

Kev siv hluav taws xob los ntawm lub teeb Kev sib txuas ua ke muab kev daws teeb meem rau qhov "peb sab uas tsis yooj yim sua" no ntawm theem molecular. Cov thev naus laus zis no tsis hloov cov ntaub ntawv tseem ceeb tab sis siv cov hluav taws xob muaj zog heev los "weld" cov tes hauj lwm peb-seem ntawm cov saw polymer. Cov txheej txheem no ua rau cov teebmeem synergistic ntawm cov qauv ntau txheej thiab ua rau cov kev txwv kev ua tau zoo ntawm cov yeeb yaj kiab hnyav.

Raws li qhov kev thov rau cov zaub mov npaj txhij thiab cov zaub mov npaj txhij txuas ntxiv nce siab, kev tua kab mob kub siab tau dhau los ua ib txoj hauv kev tseem ceeb rau kev ua kom muaj kev nyab xeeb ntawm cov zaub mov thiab ua kom lub txee ntev dua. Kev tua kab mob Pasteurization (85-95 ° C) yog siv dav rau cov zaub mov uas muaj kua qaub qis xws li mis nyuj, kua txiv hmab txiv ntoo, thiab npias, thaum kev tua kab mob kub siab, siab siab (121-135 ° C) yog qhov tseem ceeb rau cov nqaij, cov khoom lag luam taum pauv, thiab cov zaub mov muaj protein ntau uas xav tau kev tua kab mob hauv kev lag luam. Cov kev kho cua sov no tshem tawm cov kab mob me me tab sis kuj tseem muaj qhov xav tau ntau rau cov zaj duab xis ntim khoom - lawv yuav tsum tswj hwm kev ruaj khov ntawm cov qauv, kev ntseeg siab ntawm lub foob, thiab kev ruaj khov ntawm qhov loj me hauv qab qhov kub siab.

Txawm li cas los xij, cov yeeb yaj kiab thermoplastic ib txwm muaj cov kev txwv hauv kev tiv taus cua sov. Piv txwv li, polyethylene (PE) muaj qhov taw tes Vicat softening ntawm 90-110 ° C thiab pib mos ntawm qhov kub siab tshaj 85 ° C. Txawm hais tias polypropylene (PP) tuaj yeem tiv taus dej npau, nws tseem ntsib kev pheej hmoo deformation siab tshaj 121 ° C. Kev siv tshuab electron beam crosslinkingtau tshwm sim los ua tus hloov pauv kev ua si, txhim kho kev tiv thaiv cua sov ntawm qib molecular thiab daws cov teeb meem no kom zoo.

Hauv cov kab ntau lawm ntim khoom ceev ceev, txhua ob feeb suav tias yog qhov tseem ceeb rau kev ua haujlwm ntawm zaj duab xis. Kev hloov pauv ntawm ± 5% ntawm qhov nrawm ntawm cov zaj duab xis ntsws tuaj yeem ua rau cov ntawv lo tsis sib xws, cov ntim khoom xoob, thiab thaum kawg, kev tsim khoom tsis zoo. Yog tias txheej foob poob nws qhov kev kaw cua sov vim muaj roj lossis hmoov av, nws tuaj yeem ua rau xau, pob khoom tsis ua haujlwm, thiab lub sijhawm tsim khoom tsis ua haujlwm. Hauv kev lag luam xws li zaub mov thiab kev kho mob, qhov twg kev ntim khoom ruaj khov tsis tuaj yeem sib tham tau, kev ua tiav "sib xws" kev ua tau zoo yog qhov tseem ceeb dua li tsuas yog muaj cov yam ntxwv "siab heev".

Cov ntaub ntawv ib txwm siv rau hauv cov zaj duab xis ntsws thiab cov txheej kaw feem ntau ntsib kev txwv vim yog kev txav mus los ntawm cua sov ntawm lawv cov saw hlau molecular. Kev hloov pauv ntawm qhov kub thiab txias, lub sijhawm khaws cia, thiab kev ua haujlwm ceev tuaj yeem ua rau muaj teeb meem xws li kev hloov pauv ntawm tus nqi ntsws, txo qhov tiaj tiaj, thiab lub zog kaw cua sov tsis sib xws. Kev siv tshuab electron beam crosslinkingtau hloov qhov kev ua si los ntawm kev xauv cov qauv me me ntawm cov yeeb yaj kiab ntawm qib molecular, ua rau kev ua tau zoo tas mus li.

Txij li thaum Lub Yim Hli 12, 2026, European Union txoj Cai Tswjfwm Kev Ntim Khoom thiab Kev Pov Tseg Khoom (PPWR) yuav raug siv tag nrho, yuav tsum tau kom txhua yam khoom ntim uas muab tso rau hauv kev lag luam EU rov ua dua tshiab. Nyob rau tib hnub ntawd, cov kev txwv tshiab rau PFAS (perfluoroalkyl thiab polyfluoroalkyl tshuaj) hauv cov khoom ntim khoom noj yuav pib siv, nrog rau PFAS ib leeg tsis pub tshaj 25 ppb thiab tag nrho cov concentration tsis pub tshaj 250 ppb. Tsis tas li ntawd, tag nrho cov concentration ntawm lead, cadmium, mercury, thiab hexavalent chromium yuav raug txwv tsis pub tshaj 100 mg / kg. Lub caij no, Tuam Tshoj tus qauv GB 4806.10-2025 yuav pib siv rau lub Cuaj Hli 2026, txo qis qhov kev txwv kev tsiv teb tsaws chaw ntawm bisphenol A los ntawm 0.6 mg / kg mus rau 0.05 mg / kg. EU txoj Cai Tswjfwm Kev Sib Txuas Khoom Noj Plastics (EU) 2026/245 uas tau hloov kho dua tshiab, siv tau rau lub Ob Hlis 2026, kuj tseem yuav siv cov kev txwv kev tsiv teb tsaws chaw rau rau yam khoom tshiab.

Raws li cov tswv yim ntawm "kev ntim khoom huv" thiab "kev lag luam ncig" hloov zuj zus los ntawm kev pib ua lag luam mus rau qhov yuav tsum tau ua, lub teeb hluav taws xob(EB) thev naus laus zis irradiation sawv tawm. Nrog nws cov yam ntxwv "additive-free, zero-residue, ntsuab, thiab qis-carbon", EB thev naus laus zis muab cov chaw tsim khoom ntim khoom noj nrog cov kev daws teeb meem uas sib haum xeeb zoo kawg nkaus nrog cov qauv kev cai lij choj thoob ntiaj teb hauv kev nyab xeeb thiab kev ruaj khov.

Hauv kev lag luam ntim khoom, cov neeg siv khoom muaj ntau yam kev xav tau thiab tshwj xeeb rau kev ua yeeb yaj kiab. Qee qhov xav tau cov khoom thaiv siab heev kom ntev lub txee lub neej, thaum lwm tus xav tau kev ywj pheej tshwj xeeb los pab txhawb cov duab ntim tsis sib xws, lossis lub peev xwm los tiv taus cov txheej txheem sterilization kub siab. Cov txheej txheem ib txwm rau kev hloov kho cov yeeb yaj kiab, xws li kev sib xyaw, ntau txheej co-extrusion, thiab tshuaj crosslinking, feem ntau raug txwv los ntawm cov mis ruaj khov, cov txheej txheem nqaim, thiab cov voj voog hloov kho ntev, ua rau nws nyuaj rau teb sai thiab zoo rau qhov kev thov loj hlob rau cov kev daws teeb meem customized.

Lub teeb hluav taws xob(e-beam) irradiation thev naus laus zis muab txoj hauv kev tshiab thiab ua tau zoo heev los ua tiav "kev hloov kho raws li qhov xav tau" ntawm cov khoom zaj duab xis. Nws ua haujlwm ua tus "kev ua haujlwm programmer," uas tso cai rau cov chaw tsim khoom kho cov qauv ntawm zaj duab xis yam tsis hloov pauv cov qauv yooj yim. Los ntawm kev tswj hwm cov kev txwv xws li lub zog, koob tshuaj, thiab txoj kev luam theej duab, kev siv hluav taws xob e-beammuab qib siab ntawm kev ywj pheej, ua rau muaj kev hloov pauv ntawm tus qauv mus rau kev ua haujlwm raws li qhov xav tau nrog qhov tseeb tshwj xeeb.
