UPM Cov Ntaub Ntawv Tshwj Xeeb thiab Eastman tau tsim cov ntim khoom rau cov ntawv thov zaub mov uas yuav tsum muaj kev thaiv cov roj thiab cov pa nrog cov txheej txheem biopolymer.
Cov tshuaj sib xyaw ua ke Eastman's bio-based thiab compostable Solus kev ua tau zoo ntxiv nrog BioPBS polymers los ua cov txheej nyias ntawm UPM cov ntaub ntawv compostable thiab recyclable barrier puag daim ntawv.
Vim hais tias cov txheej yog nyias nyias, cov tuam txhab hais tias cov tshuaj yog tsim los "recyclable" nyob rau hauv uas twb muaj lawm fiber recycling kwj.
"Peb txaus siab los nthuav tawm cov txiaj ntsig ntawm peb txoj kev koom tes nrog kev txhim kho Eastman," said Esa Saukkonen, Tus Thawj Saib Xyuas Kev Txhim Kho Kev Lag Luam, R & D, UPM Cov Ntawv Tshwj Xeeb. "Ua ke nrog peb cov neeg koom tes, peb tab tom txuas ntxiv thawb lub hnab ntawv ua haujlwm rau kev ntim khoom fiber ntau. Piv txwv li, cov txheej txheem biopolymer tshiab no muaj kev xaiv tshiab rau cov zaub mov nyuaj rau pob, los ntawm cov ntawv thov confectionery kawg rau mince pies hauv cov zaub mov khov. aisle."
Qhov kev daws teeb meem nthuav dav cov txiaj ntsig kev txhim kho ntawm UPM Solide Lucent thiab UPM Prego barrier puag cov ntaub ntawv. UPM Cov Ntawv Qhia Tshwj Xeeb hais tias nws muab "tseem ceeb" thaum tshav kub kub sealability thaum tuav thaiv kev tiv thaiv thaum tuav, ua rau nws tsim nyog rau kev ntim khoom yooj yim.
Tsis tas li ntawd, cov thev naus laus zis tau tshaj tawm tau tshaj tawm nrog cov pa LDPE (tsawg-density polyethylene) extrusion txheej khoom.
Kev lig kev cai, kev sib tw hauv kev sib txuas cov txheej txheem extrusion nrog ntawv yog qhov adhesion ntawm txheej rau daim ntawv, tshwj xeeb tshaj yog rau bio-based lossis biodegradable extrusion txheej. UPM Cov Ntaub Ntawv Tshwj Xeeb thiab Eastman ntseeg tias qhov kev daws teeb meem tshiab no pab daws qhov teeb meem ntawd.
"Los ntawm peb txoj kev koom tes nrog UPM Cov Ntawv Tshwj Xeeb, peb tau tsim ntau yam fiber ntau ntim cov kev daws teeb meem uas yog compostable thiab integrate smoothly nrog extrusion txheej khoom," said Bhuma Rajagopalan, CASE Innovation Market Manager ntawm Eastman. "Eastman Solus additives txo cov txheej tuab, yog li txo kev siv cov yas thiab ua cov khoom ntim rov ua dua tshiab. Cov additives no ua lub luag haujlwm tseem ceeb hauv kev tsav tsheb scalable, sustainable ntawv ntim rau hom."
Cov tshuaj ntim tau raug lees paub rau kev rov ua dua tshiab raws li PTS txoj kev (PTS-RH 021/97 cat II), thiab cov khoom sib xyaw ntawm cov tshuaj tau raug lees paub rau hauv tsev thiab cov khoom siv compostability.
