PFAS—yomwe nthawi zambiri imatchedwa “mankhwala osatha”—ikuyang'aniridwa kwambiri padziko lonse lapansi. Ndi lamulo la EU la Packaging and Packaging Waste Regulation (PPWR, 2025) loletsa PFAS mu ma CD okhudzana ndi chakudya kuyambira mu Ogasiti 2026, ndi US EPA PFAS Action Plan (2021–2024) lolimbitsa malire m'mafakitale, opanga ma extrusions akukakamizidwa kuti asinthe ma polymer processing aids (PPAs) okhala ndi fluoropolymer ndi njira zina zopanda PFAS.

N’chifukwa chiyani kuli kofunikirakuchotsa PFAS mu polymer extrusion?

Zinthu za Per- ndi polyfluoroalkyl (PFAS), gulu la mankhwala osatha omwe amasokoneza endocrine, ndipo amagwirizanitsidwa ndi khansa, matenda a chithokomiro, ndi mavuto obereka. PFAS yakhala ikugwiritsidwa ntchito m'mafakitale ndi zinthu zogulira kuyambira m'ma 1940. PFAS ili paliponse m'chilengedwe chifukwa cha kapangidwe kake kokhazikika ka mankhwala. Monga mankhwala otchedwa "forever chemicals", amapezeka m'nthaka, m'madzi, ndi mumlengalenga.8 Kuphatikiza apo, PFAS yapezeka m'zinthu zosiyanasiyana (monga, zophikira zosamata, nsalu zosabala, thovu lozimitsa moto), chakudya, ndi madzi akumwa, zomwe zimapangitsa kuti anthu ambiri azitha kukumana ndi matendawa (>95%).
Chifukwa chake, kuipitsidwa kwa PFAS kwapangitsa kuti pakhale malamulo okhwima okhudza kugwiritsa ntchito kwawo mu zowonjezera za polima. Kwa opanga mafilimu, mapaipi, ndi zingwe, ma PPA achikhalidwe amakhala ndi zoopsa pakutsata malamulo ndi mbiri ya kampani.

Pansipa pali kusintha kwa malamulo ndi njira zomwe zathandizira kusinthaku, kutengera zomwe zilipo:

1. Zochita Zoyang'anira za European Union (EU):

• Choletsa cha PFAS Chomwe Chikuperekedwa ndi ECHA (2023): Mu February 2023, European Chemicals Agency (ECHA) idapereka chiletso chokwanira pa zinthu za per- ndi polyfluoroalkyl (PFAS) motsatira malamulo a REACH. Cholingachi chikukhudza mitundu yosiyanasiyana ya PFAS, kuphatikizapo fluoropolymers zomwe zimagwiritsidwa ntchito ngati zothandizira polima (PPAs). Ngakhale makampani opanga fluoropolymer akufuna kuti asachotsedwe, malangizo oyendetsera ntchito ndi omveka bwino: zoletsa zikuyendetsedwa ndi kupirira kwa chilengedwe komanso zoopsa zomwe zingachitike chifukwa cha PFAS paumoyo. Cholinga chake ndikuchepetsa kupanga, kugwiritsa ntchito, ndi kuyika kwawo pamsika, motero kupangitsa mafakitale kugwiritsa ntchito njira zina zopanda PFAS.

• Ndondomeko ya Mankhwala a EU Yothandizira Kukhazikika: Ndondomeko ya EU imagwiritsa ntchito njira yonse yothanirana ndi zoopsa za PFAS, kuika patsogolo kuthetsa zinthu zoopsa ndikulimbikitsa chitukuko cha njira zina zopanda fluorine, kuphatikizapo zomwe zimagwiritsidwa ntchito polima. Izi zathandizira kwambiri kupanga zatsopano mu ma PPA opanda PFAS, makamaka kuonetsetsa kuti malamulo okhudzana ndi kukhudzana ndi chakudya ndi ma paketi akutsatira.

• European Union Packaging and Packaging Waste Regulation (PPWR) 2025: Yofalitsidwa mu European Official Journal pa Januwale 22, 2025, PPWR ikuphatikiza kuletsa kugwiritsa ntchito PFAS mu ma CD olumikizirana ndi chakudya kuyambira pa Ogasiti 12, 2026. Lamuloli likufuna kuchepetsa kuwononga chilengedwe kwa ma CD ndikuteteza thanzi la anthu poletsa PFAS mu ma CD olumikizirana, kuphatikiza zida zothandizira kukonza ma polymer zomwe zimagwiritsidwa ntchito potulutsa filimu ya pulasitiki. Kuphatikiza apo, PPWR ikugogomezera zofunikira zobwezeretsanso - dera lomwe ma PPA opanda PFAS amapereka mwayi wowonekera - motero kumalimbikitsa kusintha kwa njira zosungira ma CD.

 2. Zochitika Zokhudza Malamulo ku United States

• Ndondomeko ya Ntchito ya EPA ya PFAS (2021–2024): Bungwe la US Environmental Protection Agency (EPA) lakhazikitsa njira zingapo zothetsera kuipitsidwa kwa PFAS:

• Kusankhidwa kwa PFOA ndi PFOS ngati Zinthu Zoopsa (Epulo 2024): Motsatira Comprehensive Environmental Response, Compensation, and Liability Act (Superfund), EPA idasankha perfluorooctanoic acid (PFOA) ndi perfluorooctanesulfonic acid (PFOS)—mankhwala ofunikira a PFAS omwe amagwiritsidwa ntchito mu PPAs—ngati zinthu zoopsa. Izi zimawonjezera kuwonekera bwino komanso kuyankha pa ntchito yoyeretsa ndipo zimalimbikitsa mafakitale kusintha njira zina zomwe sizili za PFAS.

• Muyezo wa Madzi Akumwa Wadziko Lonse (Epulo 2024): EPA idamaliza muyezo woyamba wovomerezeka wa madzi akumwa wa PFAS, cholinga chake ndi kuchepetsa kufalikira kwa madzi kwa anthu pafupifupi 100 miliyoni. Lamuloli likukakamiza mafakitale kuti achotse PFAS mu njira zopangira, kuphatikizapo PPAs, kuti apewe kuipitsidwa kwa magwero a madzi.

• Zowonjezera mu Toxics Release Inventory (TRI) (Januware 2024): EPA inawonjezera PFAS zisanu ndi ziwiri ku TRI motsatira lamulo la National Defense Authorization Act la 2020, zomwe zimafuna malipoti a 2024. Izi zimawonjezera kufufuza pa ma PPA okhala ndi PFAS ndipo zimathandizira kugwiritsa ntchito njira zina zopanda PFAS.

• Malingaliro a Lamulo Losunga ndi Kubwezeretsa Zinthu (RCRA) (February 2024): EPA idapereka malamulo oti awonjezere PFAS zisanu ndi zinayi pamndandanda wa zinthu zoopsa zomwe zili pansi pa RCRA, kulimbikitsa ulamuliro woyeretsa ndikupititsa patsogolo opanga njira zothetsera mavuto opanda PFAS.

• Ziletso Pamlingo Wa Boma: Mayiko monga Minnesota akhazikitsa ziletso pa zinthu zomwe zili ndi PFAS, monga mbale zophikira, zomwe zikusonyeza kuti pakufunika kuletsa kwambiri zinthu zomwe zili ndi PFAS, kuphatikizapo ma PPA omwe amagwiritsidwa ntchito polumikizana ndi chakudya. Mayiko ena, kuphatikizapo California, Michigan, ndi Ohio, atchula kuti palibe chomwe boma lachitapo ngati choyambitsa malamulo a PFAS pamlingo wa boma, zomwe zikulimbikitsanso kusintha kwa ma PPA opanda PFAS.

3. Ntchito Zapadziko Lonse ndi Zachigawo:

• Ndondomeko Yoyendetsera Ntchito ku Canada: Canada yakhazikitsa malamulo amphamvu ochepetsera ndikuwongolera kupanga ndi kugwiritsa ntchito kwa PFAS, zomwe zapangitsa opanga padziko lonse lapansi kusintha ma PPA okhala ndi PFAS ndi njira zina zopanda fluorine.

• Msonkhano wa ku Stockholm: Kukambirana kwapadziko lonse pankhani ya malamulo a PFAS, makamaka a perfluorooctanesulfonic acid (PFOS) ndi mankhwala ena ofanana nawo, kwakhala kukupitilira kwa zaka zoposa khumi. Ngakhale kuti si mayiko onse (monga Brazil ndi China) omwe amaletsa kwathunthu PFAS zina, njira yapadziko lonse yoyendetsera malamulo imathandizira kukhazikitsidwa kwa ma PPA opanda PFAS.

• 3M's Phase-Out Commitment (2022): 3M, kampani yayikulu yopanga PFAS, yalengeza kuti isiya kupanga PFAS pofika kumapeto kwa chaka cha 2025, zomwe zapangitsa kuti pakhale kufunikira kwakukulu kwa ma PPA omwe si a PFAS kuti alowe m'malo mwa zothandizira zochokera ku fluoropolymer m'mafakitale monga mafilimu ndi mapaipi.

4. Kutsatira Malamulo Okhudzana ndi Chakudya:

Malamulo ochokera ku US Food and Drug Administration (FDA) ndi European Food Safety Authority (EFSA) akugogomezera ma PPA opanda PFAS pakugwiritsa ntchito mankhwala okhudzana ndi chakudya.

5. Kupsinjika kwa Msika ndi Makampani

Kupatula malamulo okhwima, kufunikira kwa ogula pazinthu zosawononga chilengedwe komanso zolinga zokhazikika kwa makampani kukukakamiza eni ake amakampani ndi opanga kuti agwiritse ntchito ma PPA opanda PFAS. Izi zikuwonekera makamaka mumakampani opanga ma PPA, komwe njira zopanda PFAS zimafunidwa kuti ma plugged osinthika, mafilimu osokonekera, ndi mafilimu ochita sewero akwaniritse zomwe msika ukuyembekezera ndikupewa kuwonongeka kwa mbiri.

Yankho la Makampani: Ma PPA aulere a PFAS

Ogulitsa zinthu zowonjezera ma polima monga Silike, Clariant, Baerlocher, Ampacet, ndi Tosaf achitapo kanthu mwa kupanga ma PPA opanda PFAS omwe amafanana kapena kupitirira momwe zinthu zothandizira zochokera ku fluoropolymer zimagwirira ntchito. Njira zina izi zimathandiza kuchepetsa kusweka kwa melting, kufa, ndi kuthamanga kwa extrusion, pomwe akuwonetsetsa kuti akutsatira malamulo okhudzana ndi chakudya ndikuthandizira zolinga zokhazikika.

Mwachitsanzo,Silike SILIMER Series Polymer Extrusion Additives imapereka zopanda PFAS, njira zopanda fluorinekuti athetse mavuto okonza zinthu. Yopangidwira mafilimu opangidwa ndi blown, cast, ndi multilayer, ulusi, zingwe, mapaipi, masterbatch, compounding, ndi zina zambiri, imatha kupititsa patsogolo magwiridwe antchito amitundu yosiyanasiyana ya polyolefins, kuphatikiza koma osati kokha mLLDPE, LLDPE, LDPE, HDPE, PP, ndi polyolefins zobwezerezedwanso.
