Mukati meFDA: Maonero Akazara eFDA eKutevedzera Mutemo weFood-Contact Paper nePE Coated Paper
Kana wawana PE yakaputirwa bepa, Kapu yeChirongo, kana feni yekapu yepepa“Kutevedzera mitemo yeFDA” kazhinji ndiyo nzira yekutanga iyo mutengi wese wekuUS anoisa.
Paperjoykambani inotengesera PE- inobva kuChinaPepa Rakafukidzwa, feni yekapu yemuto wekapu uye yepepa inoshandira vanopinza chikafu kuNorth America nevagadziri vemakapu. Asi zvinorehwa ne “FDA compliance” chaizvo, kana chitupa chiripo, uye kuti ungachisimbisa sei zvakapoteredzwa nengano. Gwaro iri rekuti “Inside the FDA” rinotsanangura hurongwa hweUS hwekubata chikafu, mitemo yakasiyana yepepa kana polyethylene coating, zvinoreva chaizvo chiratidzo chikuru – chloroform-soluble extractives – uye kuti vatengi vanogona sei kusefa vatengesi “venhema-compliance” padanho rekutaura.
Sei Uchifanira Kufamba “Mukati meFDA” – US Food-Contact Regulatory Landscape
Kutarisirwa kweUS kwezvinhu zvinobata chikafu (FCM) kunoenderana neFood and Drug Administration (FDA), kwakavakirwa paFederal Food, Drug, and Cosmetic Act (FD&C Act). 1958 Food Additives Amendment yakasimbisa musimboti mukuru wekuti chero chinhu chinowedzerwa muchikafu nemaune chinoda mvumo yekutanga – pokutangira mutemo weFood Contact Substance (FCS).
FDA haipe “chitupa” chepepa kana roll chaiyo ye PE yakaputirwa bepa; pachinzvimbo pezvo inosimbisa mitemo yakapararira pa21 CFR 170–189. Kuti uishandise, sarudza nzira nhatu dzekutevedzera mitemo:
– Chikumbiro Chekuwedzera Chikafu (FAP): nzira yekare, inoda humbowo hwakasimba hwekuchengetedza hwakatumirwa kuFDA nematanho marefu ekuongorora.
– Chiziviso Chekuonana Nezvekudya (FCN): nzira huru kubvira muna 1997. Kambani inotumira chiziviso; kana FDA isingapikise mukati memazuva 120, chiziviso chacho chinova “chinoshanda.” MaFCN anochengeta mafomura acho akavanzika uye anoshanda chete kune anozivisa.
– GRAS (Inozivikanwa Seyakachengeteka): yezvinhu zvine kuchengetedzeka kwazvo kunowanzo zivikanwa nenyanzvi dzakanyatso kwanisa, kuburikidza nemhedziso yeGRAS kana chiziviso cheGRAS.
Zvimwe zvekudya zvisina kunanga — bepa, bhodhi repepa, uye mapurasitiki — zviri mu21 CFR 175–178. Pepa Nepepabhodhi iri ndere 21 CFR 176; mapurasitiki nemapolymer ari ndere 21 CFR 177. Ndiyo nzira chaiyo yekutonga yepepa rakasanganiswa rakaita sePE coated (paper base + PE coating).
Chitsauko Chepepa: Kupatsanurwa Kwakazara kwe21 CFR 176
21 CFR 176 yakatsaurirwa kuzvikamu zvemapepa nebhodhi, zvine zvikamu zvakakamurwa zvakajeka:
– 21 CFR 176.100: zvirevo zvakajairika, zvinotsanangura chiyero uye zvinosungirwa zvemapepa nebhodhi remapepa.
– 21 CFR 176.110: runyoro rwakanaka rwezvinhu zvinogona kushandiswa zvakachengeteka sezvikamu zvepepa nebhodhi remapepa — zvinhu zvinoisa saizi, zvinozadza, pigments, nezvimwewo.
– 21 CFR 176.170: inodzora zvikamu zvepepa nebhodhi repepa zvinosangana nezvikafu zvine mvura nemafuta, ichishandisa zvinonyunguduka zvinonyungudika mu chloroform sechiratidzo chezvose zvinogona kuburitswa – chiyero chinowanzo kumbirwa muUS chepepa rekubata chikafu.
– 21 CFR 176.180: inonyora zvinhu zvinotenderwa zvinogona kushandiswa sezvikamu zvepepa nebhodhi repepa zvakagadzirirwa kusangana nechikafu chakaoma, nemiganhu yekushandisa yakatarwa zvichienderana nehuremu. Cherechedza: chikamu chino hachiise nhamba dzekubvisa nhatu dze0.5 / 0.04 / 0.08 mg/in² — iyo miganhu yekubvisa ndeyezvikamu zve21 CFR 178 adjuvants (semuenzaniso, 178.2010 / 178.3120), kwete 176.180.
– 21 CFR 176.200 / 176.210: zvivharo zvakasara uye kutamiswa kwemishonga inobvisa mabhakitiriya uye mishonga inorwisa utachiona muchigadzirwa chapera.
Pfungwa huru: 176.170 inodzora huwandu hwese hwezvinhu zvakasikwa zvinoburitswa papepa rapera, nepo 176.110/176.180 ichidzora kana zvinhu zvakawedzerwa mukati zvichibvumirwa — kumberi nekumashure, zvinovhara denderedzwa riri pahwaro hwepepa.
Imba Yepamutemo yePolyethylene Coating: 21 CFR 177.1520 (Olefin Polymers)
Bepa rakaputirwa nePE harisi “pepa” rimwe chete asi rinosanganisira chigadziko chepepa pamwe nefirimu repolyethylene (PE). Chikamu chepepa chinowira pasi pe21 CFR 176, nepo firimu rePE, sejira reolefin polymer, rinofanira kugutsa 21 CFR 177.1520 (Olefin Polymers) zvakasiyana.
177.1520 inogadza kuchena uye zvinodiwa zve polyethylene nedzimwe olefin polymers, kusanganisira density ranges uye extractive ceiling (semuenzaniso, n-hexane extractives). Nemamwe mashoko, bepa rakafukidzwa nePE rinoenderana rinofanira kusangana ne176.170 (zvese zvinobviswa zve organics zvepazasi pepepa) uye 21 CFR 177.1520 (kuchena kwepolymer kwePE coating) — hapana mutsetse wega wakakwana.
Chimwe chinhu chinowanzo bvunzwa: PE inogona kushandiswa pakugadzira chikafu chinosanganiswa nefood-contact layer here? Kwete pasina kuongororwa uye mvumo yeFDA. FDA hairambidze zvachose PE inoshandiswazve, asi mapolymer akagadziriswazve anogona kushandiswa chete mukushandisa chikafu chinosanganiswa nefood-contact applications mushure mekuongorora kwakazara kweFDA, izvo zvinowanzoita kuti FDA ipe FDA No Objection Letter (NOL) yemaitiro chaiwo ekugadzirisa. PE yakajairwa isina kuongororwa haigone kushandiswa zvakananga pakugadzira chikafu chinosanganiswa nefood-contact. Ndosaka vatengesi vemapepa akaputirwa nePE vane mvumo vachisimbisa “resin yemhando yepamusoro yefekitori yePE” – inodzivisa kusava nechokwadi kwemutemo wezvinhu zvakagadziriswazve.
Muganho Mukuru: Chloroform-Soluble Extractives, Tsananguro
Bvunzo ye176.170 chloroform-soluble extractives ndiyo inonyanya kutariswa mupazano remapepa. Haipime chinhu chimwe chete; inofungidzira huwandu hwese hwezvinhu zvakasikwa zvinogona kutama kubva pamusoro pechikafu – chinhu chinochengetedza tsika yekufamba kwese.
Pfungwa yacho:
1. Sampuro inochekwa panzvimbo inozivikanwa kuti inosangana nechikafu uye yonyikwa mumudziyo wakakodzera wekudya panguva yakatarwa yekupisa nenguva yakatarwa.
2. Simulant inobviswa yopwanyika kusvika yaoma; zvasara zvinotorwazve ne chloroform.
3. Chikamu chechloroform chinobviswa huremu husingachinji uye chinoyerwa, zvichipa huwandu hwezvinhu zvinonyungudika mu chloroform.
4. Govanisa nenzvimbo ine chikafu kuti uwane mg/in², wobva waenzanisa nemuganhu.
Chloroform inoshandiswa kwete mvura nekuti inoburitsa zvinhu zvakasiyana-siyana zve organics zvisiri zve polar uye zvisina simba – lipids, polymers dzine huremu hushoma, nezvimwe zvinobatsira pakugadzira – zvichimiririra zviri nani huwandu hwezvinhu zve organics zvinogona kutamira muchikafu.
Muganho we176.170 i0.5 mg/in² — asi nemutemo unorambidza: pasi pe21 CFR 176.170 https://www.ecfr.gov/current/title-21/part-176/section-176.170(c), nhamba iyi ye0.5 mg/in² inoshanda kumagaba anoshandiswa kamwe chete ≤1 galoni (≈3.785 L); magaba makuru anoshandiswa kamwe chete anotevera 1.8 mg/in², uye zvinhu zvinoshandiswa kakawanda zvine miganhu yakasiyana. Makapu epepa nembiya zvinowira muchikamu che ≤1-galoni, saka 0.5 mg/in² ndiyo kukosha kweindasitiri — asi musiyano wemutemo haufanirwe kusiiwa. Muchiyero: 1 in² = 6.4516 cm², saka 0.5 mg/in² ≈ 0.0775 mg/cm². Mutemo uyu unotsanangurawo mamiriro ekubvisa chikafu zvichienderana nerudzi rwechikafu (chemvura, chine acid, chinwiwa …
“ND (Hazvina Kuonekwa)” zvinoreva kuti mhedzisiro iri pasi pemuganhu wekuzivisa nzira, kwete zero chaiyo — zvinoratidza kuti mwero uri pasi pekugona kwekuona kwemuchina uye uri pasi pemuganhu we0.5 mg/in². Kune vanotenga, ND zvinoreva mwero wakakwana wekuchengetedza pasi pemamiriro ezvinhu akajairika ekubata chikafu.
FDA Inomhanya Ne “Kuzvitevedzera” – Ngano dzeChitupa vs. Chokwadi
Pfungwa imwe chete inonyanya kukosha mubhuku rino rekuti “Inside the FDA”: FDA haiburitse “chitupa chekutevedzera mitemo” yezvinhu zvinosangana nechikafu. Mashoko emusika akadai sekuti “chigadzirwa chakasimbiswa neFDA” kana kuti “nhamba yechitupa cheFDA” haana kunyatsojeka panyaya yemutemo. FDA inoshandisa nzira yekuzvitevedzera – mutoro neuchapupu zviri mukambani, uye kutevedzera mitemo kunobva pamitemo chaiyo nemishumo yebvunzo dzevamwe, kwete gwaro rekubvumidza zvachose.
Pfungwa nhatu dzinowanzo vhiringidzwa:
– Chigadzirwa “chitupa cheFDA”: hachipo. FDA haipe zvitupa zvekutevedzera mitemo yezvigadzirwa.
– Kunyoresa Nzvimbo (FDA Food Facility Registration): pasi peMutemo weBioterrorism, kunyoresa kunodiwa kunzvimbo dzinogadzira, dzinogadzira, dzinorongedza, kana kuchengeta chikafu chevanhu — kwete zvega zvega pachirimwa chekudya chete. Chigadzirwa chinogadzira bepa rakaputirwa chete hachifanirwe kunyoreswa, kunyangwe vazhinji vanotenga zvinhu kunze kwenyika muUS vachiri kukumbira segwaro rekuwedzera. Iri igwaro renzvimbo, kwete chitupa chechigadzirwa.
– Kuzivisa kweFCN: kunoshanda nekusaita chimwe chinhu, kwete kubvumidzwa kwechigadzirwa chakapedzwa; mafomura acho anoramba ari epachivande uye FCN inoshanda chete kune anozivisa. Cherechedzawo nzira yekusunungurwa yeThreshold of Regulation (TOR) – zvinhu zvine huwandu hwekufamba husingapfuure 0.5 zvikamu pabhiriyoni (ppb) uye zvisiri zvinokonzera kenza zvinogona kukodzera TOR uye kudzivirira FCN yakazara; hapana kutumirwa kweFCN kwakakodzera kana TOR ikashandisa.
Saka vatengi vanofanira kutarisa chii? Chiratidzo chaicho igwaro rekambani rekutevera mitemo:
1. Zviziviso zvechinhu/musanganiswa zvinosimbisa zvikamu zvinowira mukati merunyorwa rwe176.110 rwakanaka uye 177.1520 specs.
2. Maitiro Akanaka Ekugadzira (GMP) uye humbowo hwemhando yepamusoro.
3. Chitupa chekuongorora chega chega (COA) chine girama, huremu hwekufukidza kwePE, hunyoro, kuomarara, nezvimwewo.
4. Mushumo wekuyedzwa kwekufamba kwe176.170 kubva kurabhoritari yechitatu-bato inotenderwa neISO/IEC 17025 (SGS, Intertek, Eurofins, nezvimwewo).
5. Gwaro rekambani rekuti chigadzirwa chinoenderana nemutemo / Tsamba yekushanda zvinoenderana nemutemo wakatarwa.
Mushumo webvunzo wevamwe vanhu ndiwo musimboti wekuzvitevedzera — asi mugumisiro webvunzo, kwete mvumo yeFDA. Ngatiti “inotevedzera FDA 21 CFR 176.170,” kwete “yakabvumidzwa neFDA.”
