He aha te whakaurunga o te kirihouwhngā ilms?
Ko ngā kiriata kirihou he momo rauemi pūmua taketake e tohuhia ana e tō rātou āhua angiangi, ngāwari me te whānui o te mata. Ka hangaia ēnei rauemi hangarau mā te tukatuka i ngā kapia pūmua—i ahu mai i te hinu, i ahu mai rānei i ngā puna whakahou—kia waiho hei rau tonu me te matotoru, te whānui, me ngā āhuatanga miihini e tino whakahaeretia ana. Kua tino tipu te mākete kiriata kirihou o te ao mai i tōna tīmatanga i waenganui o te rautau 20, me te whakaputanga ā-tau neke atu i te 100 miriona tāne metrika puta noa i te ao.
Ko te maha o ngā āhuatanga o ngā kiriata kirihou e ahu mai ana i te huinga ahurei o ngā āhuatanga: he māmā engari he pakari, he ngāwari engari he kaha, ā, he mārama, he pōuri rānei i runga i ngā whakaritenga hanga. Nā ēnei āhuatanga, me ngā utu hanga iti, kua waiho ngā kiriata kirihou hei mea nui puta noa i ngā wāhanga katoa o te ahumahi hou me te oranga o ia rā. Mai i te tiaki i te hou o te kai ki te whakahohe i ngā hikohiko ngāwari matatau, he maha ngā mahi a ngā kiriata kirihou e kore e kitea e ngā kaiwhakamahi mutunga engari he mea nui ki te mahi me te pumau o te hua.
Nā ngā whanaketanga hou o te pūtaiao rauemi kua whānui ake ngā āheinga o ngā kiriata kirihou ki tua atu i ō rātou mahi tuku iho. Kei roto i ngā auahatanga ko ngā kiriata e whakarerekē ana i ngā āhuatanga hei whakautu ki ngā whakaohooho taiao, ngā momo whakakapi pirau-koiora ki ngā kirihou tuku iho, me ngā kiriata ārai mahi-teitei me ngā āheinga tiaki onge. I te wā kotahi, kua akiakihia e te tipu haere o ngā āwangawanga taiao te whanaketanga o ngā pūnaha hangarua porowhita-kati me ngā rauemi kiriata koiora-e pupuri ana i te mahi me te whakaiti i te pānga taiao.
He aha te momo kiriata kirihou?
Ngā Kiriata Tino Whānui
Ko ngā kiriata polyethylene te momo kiriata kirihou e whakamahia whānuitia ana, e 40% neke atu i te katoa o ngā kiriata kirihou e whakamahia ana. Ngā Momo me ngā Āhuatanga Matua o ngā Kiriata Polyethylene:
1. Kiriata Polyethylene Matotoru-Iti (LDPE)
Ko ngā kiriata LDPE he mea e kitea ai te ngāwari, te mārama, me te kore paitini, te kore kakara. He tino pai te ātete ki te wai, te ātete ki te makuku, me te pumau o ngā matū, e pai ai mō te tākai kai, rongoā, me ngā hua o ia rā. He pai hoki ngā āhuatanga hiri wera o ngā kiriata LDPE, ā, he maha ngā wā ka whakamahia hei paparanga hiri wera i roto i ngā kiriata hiato. Heoi, he ngoikore te ātete ki te wera, ā, kāore e pai mō te tākai tunu kai i te pāmahana teitei.
2. Kiriata Polyethylene Matotoru-Teitei (HDPE)
He mārō ake ngā kiriata HDPE, he āhua mārama, he mā te tae. He pai ake te kaha kume, te ātete ki te makuku, te ātete ki te wera, me te ātete ki te hinu ki te whakatauritea ki te LDPE. He pai te HDPE mō ngā takai pakari me ngā kiriata ahumahi engari he iti ake te mārama me te kanapa.
3. Kiriata Polyethylene Matotoru-Iti Raina (LLDPE)
Ka whakakotahi ngā kiriata LLDPE i te ngāwari o te LDPE me te kaha o te HDPE, e tuku ana i ngā āhuatanga totoro pai rawa atu me te ātete ki te poka. He whānuitia te whakamahinga o ēnei i roto i ngā kiriata totoro, ngā kiriata whakaitiiti, me ngā kiriata takai, he mea tino pai mō te takai aunoa tere-teitei.
4. Kiriata Polyethylene Raina Iti-Kōmaka Metallocene (mLLDPE)
Ka hangaia ngā kiriata mLLDPE mā te whakamahi i ngā whakakorikori metallocene, ā, he nui ake te kaha pānga, te kaha hua kume, me te māramatanga pai ake i te LLDPE tikanga. Ka taea e rātou te whakaiti i te matotoru o te kiriata mā te neke atu i te 15%, ā, ka whakaiti i ngā utu rauemi. He mea noa te whakamahi i te mLLDPE i roto i ngā kiriata kati kōtuhi, ngā kiriata takai taumaha, ngā kiriata whakaiti, me ngā rauemi takai kounga teitei.
Ētahi atu Kiriata Kirihou
1. Kiriata Polypropylene (PP): He mea rongonui mō tōna ira rewa teitei (160-170°C), ā, he pai mō ngā mahi whakakī wera me te takai haumaru mō te ngaruiti. He tino ātete ki ngā matū ngā kiriata PP, ā, he maha ngā wā ka whakamahia mō ngā takai kai paramanawa me ngā takai whakahoromata taputapu hauora.
2. Ngā Kiriata Polyvinyl Chloride (PVC): He mea nui mō te mārama me te ngāwari ki te tā engari kei te heke te whakamahinga nā ngā āwangawanga mō te taiao. Ko ētahi atu whakamahinga ko te takai mirumiru me ētahi kiriata piri.
3. Ngā Kiriata Polyester (PET): He mea nui ngā kiriata PET mō ngā hikohiko ngāwari, ngā rīpene aukume, me ngā takai kai ārai-teitei, nā te mea he kaha te kume me te pumau o te wera. He tino pai ake ngā āhuatanga miihini me te ārai o te PET Biaxially-oriented (BOPET).
Ngā Kiriata Pūmua Motuhake:
1. Polyamide (Nailona): Ngā āhuatanga ārai hāora tino pai mō te tiaki kai
2. Polyvinylidene Chloride (PVDC): He mahi tino pai ki te ārai i te makuku me te hāora
3. Waikawa Polylactic (PLA): He huarahi hou e ahu mai ana i te koiora me te kaha ki te whakapūkara, ahakoa he iti noa iho i te pakarukaru—kua puta mai i ngā whanaketanga hou ngā kiriata PLA ngāwari mā te whakauru tika i ngā kirihou polyether ki roto i te mekameka polymer.
Ngā Tikanga Hanga Kiriata Kirihou
1. Te Whakaputa Kiriata Pupuhi: Ko te tukanga matua mō ngā kiriata PE, ka whakaputaina te pūmua rewa mā roto i te mata porowhita, ka pupuhihia hei mirumiru, ka whakamataohia hei hanga i tētahi ngongo ka taea te whakapapatahi hei kiriata paparua. Mā tēnei tikanga ka taurite ngā āhuatanga miihini i ngā taha mīhini me ngā taha whakawhiti.
2. Te Whakaputa Kiriata Maka: Ka whakaputaina te whakarewa polymer mā roto i tētahi mata papatahi ki runga i tētahi rōra whakamatao, ka puta he kiriata tino mārama, he matotoru ōrite hoki. He mea noa mō ngā kiriata PP me PET ina he mea nui ngā āhuatanga whatu.
3. Te Whakamarama: E whakamahia ana mō ngā kiriata PVC, ka tukuna te matū pūmua mā roto i tētahi raupapa roera wera hei whakatutuki i te whakahaere matotoru tika. Ko ngā kiriata kua whakamarama he pai ake te āhua o te mata engari he iti ake te ōrite o ngā āhuatanga ā-ringa puta noa i te whānui.
4. Te Whakarewatanga Otinga: Whakamahia mō ngā kiriata motuhake ina kore e taea te tukatuka rewa i te tino ōritetanga, i te aro rānei ki te wera. Ka whakarewaina te pūmua ki roto i te whakarewa, ka whakarewaina ki runga i te whitiki, ka whakamarokehia hei hanga kiriata—he mea noa mō ētahi kiriata pirau-koiora me ngā tono kiriuhi.
5. Te Aronga Tuatoru-rua: Ka totorohia ngā kiriata ki ngā ahunga mīhini me ngā ahunga whakawhiti, i te raupapatanga (anga whakapūmau) i te wā kotahi rānei (tukanga mirumiru), ka tino whakapai ake i te kaha, te māramatanga, me ngā āhuatanga ārai. Ko ngā kiriata PP (BOPP) me PET (BOPET) e anga-rua ana ngā anga he paerewa ahumahi mō te takai mahi-teitei.
Ngā Auahatanga Hou me ngā Auahatanga i roto i ngā Kiriata Kirihou
Kei te whanake haere te umanga kiriata kirihou, me te aro nui ki te pumau, te mahi, me te whai huatanga. Ko ētahi o ngā auahatanga rongonui ko:
1.Ngā Kaihoko Paheke Kore-PFAS:He kaihoe paheke pumau e karo ana i ngā matū per- me polyfluoroalkyl (PFAS), e aro ana ki ngā hiahia mahi me ngā āwangawanga taiao.
2. Ngā Kaupapa Whakapūmau: Kua angitu ngā kamupene pēnei i a Fox Packaging ki te whakakore i te PFAS i roto i ā rātou kōwhiringa tākai ngāwari katoa, e hangai ana ki ngā ture whānui me ngā au ahumahi. Kua whakapumautia e te US FDA he herenga tūao ki te tango i te PFAS mai i ngā tākai kai, ā, ka whai wāhi ki te whakaiti nui i te pānga o te PFAS ki ngā kai.
Ko ngā otinga auaha mō te tukatuka kore-PFAS he āwhina i ngā kiriata kirihou mai i SILIKE
He huarahi matatau tā SILIKE ki te whakamahi i ana hua raupapa SILIMER, e tuku ana i ngā hua auahaNgā āwhina tukatuka pūmua kore-PFAS (PPAs)).
