Kraft daim ntawv tais yuav tsum ua raws li * Kev Nyab Xeeb Kev Nyab Xeeb Hauv Tebchaws - Cov Khoom Siv thiab Cov Khoom Siv Paperboard thiab Cov Khoom Uas Xav Tau Los Ntawm Cov Khoom Noj * (GB 4806.8-2022). Yog tias lawv muaj txheej txheej txheej (lamination), lawv yuav tsum tau ua raws li * Kev Nyab Xeeb Kev Nyab Xeeb Hauv Tebchaws - Cov Khoom Siv Yas thiab Cov Khoom Uas Yuav Tsum Tau Los Ntawm Cov Khoom Noj * (GB 4806.7-2016). Lub teb chaws tus qauv tam sim no rau * Ntawv Tableware * (GB/T 27591-2025) kuj yuav tsim cov kev cai rau lawv. Cov ntsiab lus yog raws li nram no:
1. **Base Standard (GB 4806.8-2022):** Raws li cov khoom siv ntawv npaj rau kev sib cuag zaub mov, kraft ntawv tais yuav tsum ua raws li GB 4806.8-2022. Cov txheej txheem no tsim kom muaj cov kev xav tau meej txog cov khoom siv raw, cov khoom ntxiv, cov yam ntxwv ntawm lub cev, thiab cov cim physicochemical (xws li kev siv poov tshuaj permanganate thiab hnyav hlau tsiv teb tsaws txwv) los xyuas kom meej tias cov khoom siv ntawv tsis tso cov khoom tsis zoo thaum sib cuag nrog cov zaub mov, yog li tiv thaiv kev nyab xeeb ntawm zaub mov. Piv txwv li, tus qauv txwv tsis pub kuaj pom cov tshuaj fluorescent nyob rau hauv cov ntawv cov khoom kom tsis txhob muaj kev pheej hmoo rau kev noj qab haus huv.
2. ** Txheej Txheej Txheej Txheem (GB 4806.7-2016):** Yog tias lub tais ntawv kraft nta cov txheej tsis muaj dej (xws li polyethylene / PE zaj duab xis), nws yuav tsum ua raws li GB 4806.7-2016. Cov txheej txheem no teev cov kev txwv xws li tag nrho cov kev txwv kev tsiv teb tsaws chaw (OML), cov kev txwv kev tsiv teb tsaws tshwj xeeb (SML) rau cov khoom xws li cov hlau hnyav (xws li, lead, cadmium), thiab kev noj cov poov tshuaj permanganate, tiv thaiv kev tso tawm cov khoom tsis zoo los ntawm cov txheej yas nyob rau hauv siab - kub lossis acidic. Piv txwv li, tus txheej txheem tau teev tseg tias tag nrho cov kev tsiv teb tsaws ntawm cov txheej yas yuav tsum tsis pub tshaj 10 mg / dm² kom muaj kev nyab xeeb thaum siv . 3. Cov Qauv Yav Tom Ntej: Lub teb chaws tus qauv GB/T 27591-2025, "Paper Tableware," yog teem rau siv rau lub Kaum Ob Hlis 1, 2025. Cov txheej txheem no imposes stricter npaum li cas, raws li qhov yuav tsum tau muaj gradation, thiab cov kev xav tau load-bearing muaj peev xwm. Piv txwv li, tus nqi biodegradation yuav tsum ua kom tau raws li qhov tshwj xeeb los txo cov pa phem ib puag ncig, thiab lub peev xwm thauj khoom yuav tsum ua kom tau raws li cov txheej txheem kom ntseeg tau tias lub tais tsis yooj yim deform lossis tawg thaum siv. Txawm hais tias tus qauv tseem tsis tau muaj zog, cov tuam txhab lag luam yuav tsum ua tib zoo mloog tam sim no thiab kho lawv cov txheej txheem tsim khoom kom ua raws li cov kev xav tau yav tom ntej.
