PFAS - yomwe nthawi zambiri imatchedwa "mankhwala osatha" - ikuyang'aniridwa padziko lonse lapansi. Ndi EU's Packaging and Packaging Waste Regulation (PPWR, 2025) yoletsa PFAS m'mapaketi okhudzana ndi chakudya kuyambira Ogasiti 2026, ndi US EPA PFAS Action Plan (2021-2024) yolimbitsa malire m'mafakitale, opanga ma extrusion akukakamizidwa kuti alowe m'malo mwa fluoropoly-PFA-PFAsfreemer njira zina

Chifukwa chiyani kuli kofunikirakuchotsa PFAS mu polymer extrusion?

Per- ndi polyfluoroalkyl substances (PFAS), gulu lamankhwala omwe amasokoneza endocrine, omwe amalumikizidwa ndi khansa, matenda a chithokomiro, komanso zovuta zakubala. PFAS yakhala ikugwiritsidwa ntchito m'makampani ndi zinthu zogula kuyambira 1940s. PFAS imapezeka paliponse m'chilengedwe chifukwa cha kukhazikika kwawo kwamankhwala. Zomwe zimatchedwa "mankhwala osatha", apezeka m'nthaka, m'madzi, ndi mpweya.8 Kuwonjezera apo, PFAS yapezeka muzinthu zosiyanasiyana (monga, zophika zopanda ndodo, nsalu zosasunthika, thovu lozimitsa moto), chakudya, ndi madzi akumwa, zomwe zimapangitsa kuti anthu ambiri azidziwika (> 95%).
Chifukwa chake, kuipitsidwa kwa PFAS kwapangitsa kuti pakhale malamulo okhwima ogwiritsira ntchito pazowonjezera za polymer extrusion. Kwa opanga mafilimu, mapaipi, ndi zingwe, ma PPA achikhalidwe amakhala pachiwopsezo pakutsata komanso mbiri yamtundu.

M'munsimu muli zosintha zenizeni ndi zoyambitsa zomwe zikuthandizira kusinthaku, kutengera zomwe zilipo:

1. European Union (EU) Regulatory Actions:

• Kuletsa kwa PFAS (2023) kwa ECHA: Mu February 2023, European Chemicals Agency (ECHA) inakonza zoti pakhale ziletso zambiri pa per- and polyfluoroalkyl substances (PFAS) pansi pa lamulo la REACH. Malingalirowa amayang'ana mitundu yambiri ya PFAS, kuphatikiza ma fluoropolymers omwe amagwiritsidwa ntchito ngati polima polima (PPAs). Ngakhale makampani amtundu wa fluoropolymer akufuna kuti anthu asakhululukidwe, malangizo owongolera ndi omveka bwino: zoletsa zikuyendetsedwa ndi kulimbikira kwachilengedwe komanso zoopsa zomwe zingachitike paumoyo wa PFAS. Cholinga ndikuchepetsa kupanga, kugwiritsa ntchito, ndi kuyika kwawo pamsika, zomwe zimapangitsa kuti mafakitale azitengera njira zina zopanda PFAS.

• EU Chemicals Strategy for Sustainability: Dongosolo la EU likutenga njira yothanirana ndi ngozi za PFAS, kuyika patsogolo kuchotsa zinthu zovulaza ndikulimbikitsa chitukuko cha njira zina zopanda fluorine, kuphatikiza zopangira polima. Izi zakulitsa luso la ma PPA aulere a PFAS, makamaka kuwonetsetsa kuti akutsatira malamulo okhudzana ndi chakudya komanso kakhazikitsidwe.

• European Union Packaging and Packaging Waste Regulation (PPWR) 2025: Lofalitsidwa mu European Official Journal pa Januware 22, 2025, PPWR ikuphatikiza kuletsa kugwiritsa ntchito PFAS pakupakira chakudya kuyambira pa Ogasiti 12, 2026. zipangizo, kuphatikizapo zipangizo polima processing ntchito pulasitiki filimu extrusion. Kuphatikiza apo, PPWR ikugogomezera zofunikira zobwezeretsedwanso - malo omwe ma PPA opanda PFAS amapereka mwayi wowonekera bwino - potero kulimbikitsanso kusinthira ku mayankho okhazikika.

 2. United States Regulatory Developments

• EPA's PFAS Action Plan (2021–2024): Bungwe la US Environmental Protection Agency (EPA) lakhazikitsa njira zingapo zothetsera kuipitsidwa kwa PFAS:

• Kutchulidwa kwa PFOA ndi PFOS Monga Zinthu Zowopsa (Epulo 2024): Pansi pa Comprehensive Environmental Response, Compensation, and Liability Act (Superfund), EPA idasankha perfluorooctanoic acid (PFOA) ndi perfluorooctanesulfonic acid (PFOS)—mankhwala ofunikira a PFAS omwe amagwiritsidwa ntchito muzinthu zowopsa za PPA. Izi zimakulitsa kuwonekera komanso kuyankha pakuyeretsa komanso kulimbikitsa mafakitale kuti asinthe njira zina zomwe si za PFAS.

• National Drinking Water Standard (Epulo 2024): EPA inamaliza mulingo woyamba wamadzi akumwa wovomerezeka mwalamulo wa PFAS, ndicholinga chochepetsa kuwonekera kwa anthu pafupifupi 100 miliyoni. Lamuloli mosalunjika limakakamiza mafakitale kuti achotse PFAS pakupanga, kuphatikiza ma PPA, kuti aletse kuipitsidwa kwa magwero amadzi.

• Toxics Release Inventory (TRI) Zowonjezera (Januwale 2024): EPA inawonjezera PFAS zisanu ndi ziwiri ku TRI pansi pa lamulo la 2020 National Defense Authorization Act, lomwe likufuna kupereka malipoti a 2024. Izi zimawonjezera kuwunika kwa ma PPA omwe ali ndi PFAS komanso kulimbikitsa kutengera njira zina zopanda PFAS.

• Resource Conservation and Recovery Act (RCRA) Proposals (February 2024): EPA inakonza malamulo oti awonjezere PFAS zisanu ndi zinayi pamndandanda wa zigawo zoopsa zomwe zili pansi pa RCRA, kukulitsa ulamuliro woyeretsa ndikukankhiranso opanga ku mayankho opanda PFAS.

• Ziletso za Boma: Maiko monga Minnesota akhazikitsa zoletsa zinthu zomwe zili ndi PFAS, monga zophikira, zomwe zikuwonetsa kuphwanya kwakukulu kwa zinthu zochokera ku PFAS, kuphatikiza ma PPA omwe amagwiritsidwa ntchito polumikizana ndi chakudya. Maiko ena, kuphatikiza California, Michigan, ndi Ohio, anenapo kusowa kwa boma ngati oyendetsa malamulo a PFAS aboma, kulimbikitsanso kusintha kwa ma PPA opanda PFAS.

3. Ntchito Zapadziko Lonse ndi Zachigawo:

• Canada's Regulatory Framework: Canada yakhazikitsa malamulo amphamvu ochepetsera ndikuwongolera kupanga ndi kugwiritsa ntchito PFAS, zomwe zimalimbikitsa opanga padziko lonse lapansi kuti alowe m'malo mwa PFAS-based PPAs ndi njira zina zopanda fluorine.

• Stockholm Convention: Kukambitsirana kwapadziko lonse pa malamulo a PFAS, makamaka perfluorooctanesulfonic acid (PFOS) ndi mankhwala ogwirizana nawo, kwakhala kukuchitika kwa zaka zopitirira khumi. Ngakhale si mayiko onse (mwachitsanzo, Brazil ndi China) omwe amaletsa kwathunthu PFAS ina, zomwe zikuchitika padziko lonse lapansi pakuwongolera zimathandizira kukhazikitsidwa kwa ma PPA opanda PFAS.

• Kudzipereka kwa 3M's Phase-Out (2022): 3M, wopanga wamkulu wa PFAS, adalengeza kuti isiya kupanga PFAS kumapeto kwa chaka cha 2025, zomwe zidapangitsa kuti ma PPA omwe si a PFAS alowe m'malo mwazinthu zopangira ma fluoropolymer m'mafakitale monga mafilimu ndi kutulutsa mapaipi.

4. Kugwirizana ndi Chakudya:

Malamulo ochokera ku US Food and Drug Administration (FDA) ndi European Food Safety Authority (EFSA) akugogomezera ma PPA aulere a PFAS pamapulogalamu okhudzana ndi chakudya.

5. Kupanikizika kwa Msika & Makampani

Kupitilira malamulo owongolera, kufunikira kwa ogula pazinthu zokomera zachilengedwe komanso zolinga zokhazikika zamabizinesi zikukakamiza eni ake ndi opanga kuti atengere ma PPA opanda PFAS. Izi zikuwonekera makamaka m'makampani onyamula katundu, pomwe mayankho opanda PFAS amafunidwa kuti azitha kuyika, mafilimu owombera, ndi makanema oponyedwa kuti akwaniritse zomwe msika ukuyembekezeka ndikupewa kuwononga mbiri.

Kuyankha Kwamakampani: PFAS-Free PPAs

Othandizira ma polima akuluakulu monga Silike, Clariant, Baerlocher, Ampacet, ndi Tosaf ayankha popanga ma PPA opanda PFAS omwe amafanana kapena kupitilira magwiridwe antchito a fluoropolymer. Njira zina izi zimathandizira kuchepetsa kusungunuka kwa fracture, kufa kumanga, ndi kuthamanga kwa extrusion, ndikuwonetsetsa kutsatira malamulo okhudzana ndi chakudya komanso kuthandizira zolinga zokhazikika.

Mwachitsanzo,Silike SILIMER Series Polymer Extrusion Additives imapereka PFAS-free, mankhwala opanda fluorinekuthana ndi mavuto processing. Zopangidwira mafilimu owulutsidwa, oponyedwa, ndi ma multilayer, ulusi, zingwe, mapaipi, masterbatch, kuphatikizira, ndi zina zambiri, zimatha kupititsa patsogolo ntchito ya ma polyolefin osiyanasiyana, kuphatikiza koma osangokhala mLLDPE, LLDPE, LDPE, HDPE, PP, ndi polyolefin zobwezerezedwanso.

Kodi ma PPA opanda PFAS a FDA ndi EFSA amagwirizana? → Inde, mayankho ochokera ku Silike, etc. amakumana ndi malamulo okhudzana ndi chakudya.

Ndi mafakitale ati omwe amagwiritsa ntchito ma PPA opanda PFAS? → Kuyika, filimu yowombedwa, filimu yoponyedwa, chingwe, ndi kutulutsa chitoliro.

Kodi zotsatira za kuletsa kwa EU PFAS pakupanga zidakhudza bwanji? → Kuyika kwazakudya kuyenera kukhala kopanda PFAS pofika Ogasiti 2026.

Kutuluka kwa PFAS-based PPAs sikungathekenso-ndizotsimikizika. Ndi malamulo a EU ndi US akuyandikira, komanso kukakamiza kwa ogula, opanga ma extrusion akuyenera kusintha kupita ku PFAS-free polima zothandizira polima kuti akhalebe ampikisano, omvera, komanso okhazikika.

Mtsogolo-umboni wanu extrusion ndondomeko.Onani ma PPA opanda SILIKE PFAS lero kuti muwongolere magwiridwe antchito komanso kutsata.
