Mahi Tinta Pāpātihana ki runga i ngā Paparanga Pāpātihana Parau

Te Āhua o te Tinta Pāpātihana me te Tere Whakauru ki ngā Tautoheke o te Rangi Ipu Pāpā

Ko te mata o ngā ipu pepa he iti noa ngā pōro rānei me ngā ahua mātātoko e hiahiatia ana ētahi ahuatanga motuhake mō te inika hei tā karapu. He pai rawa te mahi a te inika waiarai e torotoro ana pea i te whakamātau e whakamahia ana i te wā o te tā, engari ka pakari anō rānei i te wā e pā ana ki te mata. Ka taea e tēnei ahuareka te rere haere tonu o te inika ki roto i te pepa kaua ko te nuinga o te rere. I runga i te papahiko taumaha ake (e 300 hākari ia mitarau tapawhā), ka tango inu te inika tino marie, heoi anō i roto i te haurua hoki, e āwhina ana i ngā tae kia tu pū atu ai, ā, kaitea atu ngā tohumotu hākinakina e kīia nei ko te 'dot gain'. Ko te aha e paingia ana he tino maama ake i te tirohanga matātoko: ko te waiarai o te inika e tāwhai ana ki ngā kowhatu, ā, ko ngā pārtihikara tae kei runga, ā, ka hangaia ngā whakaahua maama kore noa i te whakamāki i te hanganga o te ipu. Mō te nuinga o ngā kaitā, ka mōhio rātou ko te taurite e waenganui ana i te tāwhai me te here ki te mata he mea matua herekau mō te hua kounga ki ēnei momo matātoko pakipaki.

Takitahi Whakamātau: Tinta Water-Based Flexo ki te Paparanga Penei 350 gsm (Kaihanga Kōpae Matua, 2023)

I whakaatu tētahi whakamātau 2023 me tētahi kaihanga kōpae matua i te pono o te tinta water-based flexo ki te paparanga penei mō kai. I ngā rēiti 10,000-ironga, kua eke te takotoranga ki:

• 40% he harapiro ake i ngā kōwhiringa tuanui
• Kāore he korarora i muri i ngā tāwhai whakamātau mō ngā inu hauhake

Kua pupū te ata (94.5 L* uara) o te mata 350 gsm ahurea, ahakoa te kī tonu ki te tinta, ka whakatairangia te whaiwāhi o flexo ki ngā pūkoro kai herekore. I heke te waihanga whakaputa umanga 18% tau-a-tau—ka whakapumautia te āheinga mo ngā tono rahi.

Ngā Takotoranga Tinta Flexo Haumaru mō Kai: Te Arataki, Te Titenga Tārua, me te Arataki Herehere

FDA 21 CFR §175.105 me ngā Tōaitanga EU 10/2011 mō te Whakapā atu ki te Kai

Me whai ngā inika Flexo e pā ana ki te kai i ngā ture ā-ao kia ārai ai i ngā matū e neke ana ki roto i ngā mea e kai ana te tangata. E whai ture ana te FDA i raro i te wāhanga 21 CFR 175.105 e here ana i ngā mea e pā ana ki te kai takotoranga, ā, i roto i Ūropi, ko te Ture 10/2011 e tautapa ana i ngā parakirini anuanu mō ngā mea kino pērā i ngā mōrearea e hua ai te matepukupuku, arataki noa i te 0.01 miramita pera i te kilokaramu. I puta he raru nui i te tau 2005 ināia nei i tīmata ai ētahi hua taranata ki te tango mai i ngā tepu nā te nuinga o ētahi matū mai i ngā inika UV e rewa ana ki roto i a rātou. Me whakamahi ēnei tari whakahaere i ngā toihau whakamātautau takatoru hei tiro whakaaetia, e whakamahia ana hauhake motuhake e te FDA. Mō ngā kai hinu ka whakamahia ngā horo'uta etanola, engari mō ngā kai horoiwhare, ka pai ake ngā horo'uta e pā ana ki te wai.

Te Take E Dominant Ana Te Inika Flexo Hora Wai Nā Te Itinga Iti O Ngā Horo'uta Uru Auraki Me Te Mōrearea Neke

Kua wehe kē ngā karaihe takotoranga parakirini (VOCs) e mōhiotia ana mātou kua kino ana mō te hauora me te taiao ki te whakamahi i ngā rāwekenga pāpāho e tuhinga ana ki te wai i te tā kupiki anuanu. E ai ki te rangahau mai i te Pūnaha Tākirihana, Pūtaiao Pakihi i te tau 2023, kua penapena ake ēnei kōwhiringa e 92% te whakaiti i ngā tūponotanga o te nekenga ki te atamira tāpiri i te tā kupiki arataki. He aha te take e pai ai ēnei? Ko ngā tae e whakamahia ana he matotoru ake te inenga molekīhia nā reira ka pakari ake ki ngā muka pepa engari kāore i te noho pakuwekawe pērā i ngā tā takotoro, e waiho nei i ngā toipoto parakirini. Kotahi atu herenga nui ko te aukati i te "tā kaupeka inaianei" ina uru katoa ngā ipu, ka tākarotia ngā mea kāore e hiahiatia i tētahi ki tētahi. Anō hoki, kei te pai tonu rātou i te wera i ngā mahi tāpoko hauwera, ā, kei raro tonu ngā rāwekenga kāore i te wehea i raro ika 0.1 ngā wāhi i ngā piriona i te roanga o ngā huinga whakangao.

Te Ōrite o ngā Momo Tā Flexo mō ngā Ipu Pepa me ngā Paripari

Tinta UV-Curable Flexo: Mākae me te Tere ki te Tere, engari He Herenga ki ngā Tautohe

Ko ngā inika māmā UV e tu ana tonu pea mō te pupuri i te mata kua whakapuruia me te horapa tino rapa – ko te mea hiahiatia e ngā kaihanga mō ngā rorohiko rahi o ngā kapu pepa e neke ana i te 500 mita i ia meneti. Ko te ara e māmā ai ngā inika tūmatanui ki raro i te āhua UV kia kaua ai e pakaru pea ka tuia, nō reira ka noho paku, ka noho ma te takotoranga tuhituhi ahakoa kei runga papahou kua paopaoia. Engari he take kei te mahi me ngā paraka penei rawa mai i te pepa neke ake i te 350 karamu i ia mita tapawhā. E hāngai ana ēnei matapara ki te porowhewa, kia wera ai te āhua UV kia tae atu ki ngā ipo katoa mō te māmātanga tika. He aha te take e uru mai nei? Nō reira, he piri ake te tikanga o ngā inika e kore ai e hinga roa ki roto i ngā whatu engari e pupuri ana i ngā īngoa pātata pai. Ko ngā toihau tuhituhi e noho ana ki ēnei wero e kitea ana e rerekē ana i ngā rāwekenga, e rerekē ana i ngā tautuhinga taputapu kia taea ai te huinga o ngā putanga e whakaae ana.

Tinta Pāpāhua Pāpā: He Iti Haere Te Whakamahi Nā Te VOCs Me Te Tōmuri Herehere

Kua tata te wā mō ngā inka paraihe pātui mā te paraihe i ngā kōpae kai, nā te mea ka tuku aua hua i te nuinga o ngā VOCs. Kei te tata ki te 250 grama ia litra te rārangi, e toru ngā wā te nui ake i te mea e whakaae ana te EPA hei haumaru. Kua raru hoki te whakahaere ā-motu i tēnei take. Hei tauira, ko te Rārangi Whakaputanga a te EU mō ngā Hua Whakaputanga, ka taea e ngā kamupene te ririhau tae atu ki te $740,000 ā, e ai ki ngā ripoi hou ake mai i te Rōpū Ponemon. Hei tētahi atu raru hoki kei konei. Ka taea e te toluene me te xylene e waiho ana i muri i te tuhinga teka ki roto i ngā inu, nō reira e kore e tika ngā inka paraihe mō ngā mea e whakapā ana ki te kai tūturu. Ahakoa kua pakari ki ngā paparanga paraihe peita i mua, kāore he take ake tēnei anuanu. Kua huri tino te takotoranga o te mākeke i ngā tau kua pāhua nei. I ngā kaihanga, i ngaro te haurua o rātou pakihi mai i te whakamahi i ēnei inka tuku iho mai i te tau 2018, i rere atu rātou ki ngā kōwhiringa mā te wai e ū ana ki ngā paerewa FDA (21 CFR §175.105) me ngā tikanga a te European Union (EU 10/2011).
