Raws li lub hauv paus ntim nruab nrab rau niaj hnub nrawm- txav cov khoom siv (FMCG), cov khob ntawv tau hloov pauv tas li los ntawm kev hloov kho thev naus laus zis tsom rau kev ua haujlwm ntawm cov khoom siv thiab cov kev xav tau ib puag ncig. Tam sim no, cov khoom lag luam tseem ceeb tau nias los ntawm cov khoom noj -qib nkauj xwb ntoo pulp lossis bagasse fiber. Ib qho - txheej txheej tsim yog tsim rau cov dej txias, thaum ob npaug - txheej txheej (nrog rau txheej sab hauv ntawm PE lossis PLA) qhov teeb meem xau thiab rwb thaiv tsev rau cov dej kub. PE-coated ntawv khob, thaum qis- tus nqi, tuav 80% kev ua lag luam, tab sis lawv tsis yog{10}} degradability ua rau lawv muaj kev cuam tshuam loj rau ib puag ncig. Emerging PLA bio-raws li txheej txheej yog degradable nyob rau hauv industrial composting tej yam kev mob. Txawm hais tias muaj 30% -40% tus nqi tsim khoom ntau dua, lawv tau dhau los ua qhov kev xaiv zoo tshaj plaws rau kev ua raws li European thiab Asmeskas kev lag luam.
Technical barriers nyob rau hauv kev lag luam yog feem ntau pom nyob rau hauv cov txheej txheem luam ntawv. Yuav kom ua tau raws li cov qauv kev nyab xeeb ntawm cov zaub mov, cov khob ntawv feem ntau yog luam tawm nrog dej -raws li cov flexographic inks thiab UV kho tshuab kom txo qis cov organic compound emissions. Nano-silicon txheej thev naus laus zis tsim los ntawm lub tuam txhab Nyij Pooj tso cai rau lub khob ntawv tuaj yeem tiv taus qhov kub ntawm 85℃yam tsis muaj txheej txheej, qhov kev ua tiav uas tuaj yeem hloov kho cov txheej txheem tsim khoom ib txwm muaj. Tuam Tshoj, lub ntiaj teb no tus loj tshaj plaws daim ntawv khob tsim, yuav ntau tshaj 60 billion khob nyob rau hauv 2023. Txawm li cas los, recycled pulp account rau tsawg tshaj li 5% ntawm raw khoom, ho poob luv luv ntawm EU qhov yuav tsum tau 30% recycled fiber ntau quota.
Kev ua lag luam tam sim no yog polarized: cov khoom noj ceev ceev nyiam khob nrog 0.08-0.12mm lub cev tuab dua rau kev tuav tau zoo, thaum lub khw kas fes cov khw muag khoom ua kom tiav matte tiav thiab kev cai- zoo li tuag- txiav cov txheej txheem. Qhov tseem ceeb, cov dej-raws li acrylic nplaum tau tsim los ntawm Henkel Group ntawm lub teb chaws Yelemees ua tiav kev sib txuas ntawm cov txheej txheej thiab cov ntawv hauv paus, tuav cov txheej txheem kev ncaj ncees ntawm qhov kub ntawm -20℃txog 120℃. Raws li kev txwv cov yas thoob ntiaj teb hnyav zuj zus, xyoob fiber ntau daim ntawv khob nrog traceable carbon footprints thiab compostable txheej thev naus laus zis yuav dhau los ua qhov tseem ceeb ntawm cov khoom sib tw tom ntej. Qhov no xav kom cov tuam txhab lag luam ib txhij txhim kho cov saw hlau pob tshab thiab cov kev daws teeb meem kev lag luam ncig.
