Health chakudya ma CD zipangizo alibe ogwirizana muyezo panopa zoweta osati kupanga ogwirizana, yovomerezeka ntchito ya zipangizo thanzi chakudya ma CD, ndi ochepa mankhwala mu muyezo malamulo, monga kusintha ma CD wa GB/T10004 & ndash;
2008 atanyamula filimu gulu pulasitiki, thumba, youma pawiri extrusion pawiri, 'zizindikiro za zotsalira zosungunulira mu lolingana makonzedwe.

Miyezo yambiri yaukhondo ya zinthu zolongedza chakudya sikugwira ntchito pakali pano mitundu yochulukirachulukira ya mapaketi a chakudya.
Kwa zosungunulira zotsalira kudziwika, mayiko osiyanasiyana pa mipherezero ya makonzedwe ake.
Mu GB/T10004 & ndash;
2008 kulongedza pulasitiki gulu filimu, thumba, youma pawiri extrusion pawiri, 'waukulu makonzedwe mu muyezo zosungunulira yotsalira kuchuluka si oposa 5 mg/m2, koma sanatchule mtundu wa zosungunulira, mu osiyanasiyana 5 mg/m2 onse mitundu ya zosungunulira kuchuluka komanso sapanga mwatsatanetsatane magawano.
Muyezo wa National Health umaletsanso kugwiritsa ntchito zinyalala za pulasitiki ngati zopangira zopangira zakudya zamapulasitiki.
Koma palinso kubisa kuopsa, amapangidwa ndi mafakitale zopangira pulasitiki chakudya muli.
Kuti mulingo wa index wa chidebe cha pulasitiki ukhale wotayirira kwambiri, komiti yapadziko lonse lapansi ikugwira ntchito yokonzanso ndi kukonza ntchito yokhazikika.

Ambiri ma CD katundu mankhwala mfundo si gawo lofunika kwa zosungunulira zatsalira kudziwika muyezo kufotokoza ena yosavuta zomverera, monga kulongedza katundu sayenera kukhala ndi fungo lachilendo, kunyamula akuwukha madzi sangakhale ndi fungo lachilendo, etc. palibe zizindikiro za kuchuluka kwachulukidwe zomwe zimayikidwa patsogolo.
Kupaka chakudya m'kati mwa kupanga ndi kosapeweka kulipo zosungunulira zotsalira.
Mu gravure kusindikiza pulasitiki gulu zinthu ndi zosungunulira youma pawiri ndondomeko, ayenera kugwiritsa ntchito zambiri zosungunulira organic monga toluene, ethyl acetate ndi ethyl ketone, etc. kukhala nthunzi, koma pazifukwa zosiyanasiyana mu kupanga kwenikweni padzakhala zambiri kapena zochepa si kwathunthu kosakhazikika zosungunulira, wotchedwa zosungunulira zotsalira.
Zosungunulira zotsalira ndi kuphatikiza mitundu ingapo ya zosungunulira, nthawi zambiri pamene zili zotsalira zosungunulira pansi pa mtengo wina wa fungo la anthu sangamve kukhalapo kwake, koma zotsalira za zosungunulira zambiri zomwe anthu amazimva amatha kuzizindikira.
Monga PVC (

Kukulunga kwa pulasitiki ku khansa kwadzetsa zovuta m'banja.
Mtengo wa GB9681—
1988 chakudya ma CD PVC akamaumba mankhwala muyezo thanzi 'mwachindunji, vinilu kloridi monoma zili zosakwana kapena wofanana 1 mg pa kilogalamu.
A vinyl chloride monomer zikuchokera zili PVC chodyera filimu, pambuyo zimathandizira kuti thupi la munthu ndi carcinogenicity.
European Union ndi United States, Japan, aletsa izi zomwe zimagwiritsidwa ntchito ngati chakudya.
Kusinthidwa kangapo, koma makamaka kuti ena mwa magawowa asinthe.

Zochitika zamafilimu a Cling & ponseponse;
Apanso adavumbulutsa kuti miyezo yoyenera yadziko lathu idapereka kuchedwa kwantchito.
Chifukwa chake zinthu zolongedza chakudya kuti zifufuze zotsalira za zosungunulira kuti mupange index ya kuchuluka ndikofunikira.
