Ngā kiriata whakakotahi wera me te makariri

He aha ngā Kiriata Whakakotahi Wera me ngā Kiriata Matao?

Ko ngā kiriata hiato wera me te makariri he kiriata kirihou maha-paparanga i hangaia hei mahi i raro i ngā tukanga here wera me te pēhanga taiao.
Ko te tikanga he mea hanga mai i ngā rauemi pēnei i te PET, BOPP, PE, CPP, Nylon rānei kua whakakikoruatia ngātahi mā te whakamahi i ngā piripiri, i te whakakotahitanga rānei.
He whānuitia te whakamahinga o ēnei kiriata i roto i ngā mahi takai, tā, whakakikorua, me te whakamahana nā te mea he ngāwari ki te wera me te hanganga.

He aha ngā rerekētanga matua i waenga i ngā kiriata hiato wera me ngā kiriata hiato makariri?

Ko ngā kiriata hiato wera e hiahia ana ki te wera me te pēhanga hei hono—e whakamahia whānuitia ana i roto i ngā mahi whakapiri wera, hiri wera rānei.
I tētahi atu taha, ka taea te whakamahi i ngā kiriata hiato matao mā te whakamahi i ngā piripiri tairongo-pēhanga me te kore wera, kia pai ai mō te whakapiri matao, ngā mahi pāmahana iti rānei.
Ko ētahi kiriata hiato he mea hanga hei tautoko i te hononga wera me te makariri, e tuku ana i ngā tikanga tono maha.

He aha ngā rauemi e whakamahia whānuitia ana i roto i ngā kiriata hiato wera me te makariri?

Ko ngā hanganga rauemi noa ko:
• PET/PE
• BOPP/CPP
• Nailon/PE
• BOPP/PE me te EVA, ngā piripiri whakarewa rānei.
Ka whakaratohia e ēnei huinga ngā āhuatanga e hiahiatia ana pērā i te tiaki ārai, te ātete wera, te mārama, me te āheinga ki te hiri.

He aha ngā whakamahinga noa o ngā kiriata hiato wera me te makariri?

He whānuitia ngā ahumahi e whakamahia ana ngā kiriata hiato, tae atu ki:
• Ngā takai kai ngāwari (ngā putea kai mātao, ngā kai tio, ngā putea miraka)
• Te whakakikoruatanga wera o te pepa, kāri, ngā takai ngāwari rānei
• Te hiri o ngā putea rongoā me te hauora
• Te takai whakamarumaru, te takai tiaki rānei
• Ngā tapanga, ngā rauemi pānuitanga, me ngā pāpāho tā kua whakakikoruatia
Nā te ngāwari ki te urutau ki ngā pāmahana, he mea pai mō ngā tukanga aunoa, ā-ringa rānei.

He pai ēnei kiriata hiato mō ngā takai kai?

Ae, he maha ngā kiriata whakakotahi wera me te makariri e hangaia ana me ngā kapia me ngā piripiri haumaru mō te kai.
Ka tutuki i a rātou ngā ture whakapā kai a te FDA, EU, me te GB, ā, he pai rawa atu hoki ngā āhuatanga ārai ki te makuku, te hāora, me te kakara.
He mea whakamahi noa i roto i ngā putea korehau, ngā putea retort, me ngā takai kai.

He aha ngā painga o te whakamahi i ngā kiriata whakakotahi wera me te makariri?

• He kaha ā-mīhini teitei me te ātete poka
• He tino pai te tā me te maeneene o te mata
• He kaha te piri ki te pepa, ki te papa, ki ētahi atu kiriata rānei
• Ātete ki te hinu, te ngako, me ngā matū
• Hototahi ki ngā tukanga hiri-wera me te whakamaroke-makariri
• He mahi ārai ka taea te whakarite me ngā paparanga whakarewa, paparanga paninga rānei

He aha ngā matotoru e wātea ana mō ngā kiriata hiato wera me te makariri?

Ka rerekē te matotoru i runga i te hanganga kiriata me te whakamahinga, mai i te 20 maikorona ki te 150 maikorona.
Ko ngā kiriata angiangi (hei tauira, 25–40 maikorona) ka whakamahia mō te whakapiripiri, mō ngā paparanga o roto rānei, ko ngā kiriata matotoru (neke atu i te 80 maikorona) ka pai ake te kaha me te hiri mō te takai o waho.
Ka taea e ngā kiriata maha-paparanga te whakakotahi i ngā inenga rerekē mō te arotau i te mahi.

Ka taea te tā, te whakakikorua rānei i ēnei kiriata?

Ae, ko te nuinga o ngā kiriata hiato ka taea te tā mā te gravure, flexographic, matihiko rānei.
Ko ngā putanga whakarewa (pērā i te PET whakarewa, BOPP rānei) ka whakarato i ngā āhuatanga ārai whakarei ake me ngā pānga tirohanga mō ngā takai kounga teitei. Ko
te maimoatanga corona, te maimoatanga matū rānei ka whakarite kia kaha te piri o te waituhi me te whakaputa tae kanapa.

Ka taea te hangarua anō i ngā kiriata wera me ngā kiriata makariri?

Kei te hanganga o te rauemi te tikanga.
He ngāwari ake te hangarua i ngā hanganga rauemi-kotahi pēnei i te PE/PE, PP/PP rānei.
He uaua ake te hangarua i ngā kiriata hiato rauemi-maha (hei tauira, PET/PE, BOPP/Nailona rānei) engari ka taea te hanga kia pai ake te taiao mā te whakamahi i ngā piripiri kore-whakarewa, i ngā paparanga pirau-koiora rānei.
Kei te piki haere te tuku a ngā kaihanga i ngā kiriata hiato rauemi-kotahi, ka taea rānei te hangarua mō ngā otinga tākai tauwhiro.

He aha te roa o te ora me te roa o te rokiroki e taunakitia ana?

I raro i ngā tikanga rokiroki tika—he matao, he maroke, ā, he tawhiti atu i te rā tika—ko te roanga o te ora o ngā kiriata whakahiato he 12 ki te 18 marama.
E taunakihia ana te rokiroki i roto i te taiao e whakahaerehia ana te pāmahana (15–25°C) hei ārai i te piko, te ngaronga o te piri, te pirau rānei o te tānga.
