Ngā Whakamātautau Tāwhai o BOPP: Ngā Whai Hua Ārai Taiao

He aha te take i tēnei a BOPP te whakamātua o ngā whakamātautau whakamātātui pūrākau e whai ana i te taiao

Te iti o te rākau hāngā āhua me ngā hāngā hōu o te whakamātātui BOPP

Ko te whakamahinga o te BOPP (Biaxially Oriented Polypropylene) i tēnei wā he nui ngā whai hua mō te whakamātau, nā te whakamāhi i te hiko i te ara e pai ake ana. Ko ngā pākenga o tēnei wā kei te whakamāhi i ngā rākau hiko kia māhuhu ake i ngā hāpua hiko i ngā mahi, ā, kei te whakamāhi hoki i ngā mōtāhi hiko kia pai ake, ā, ko ēnei e rua i tahi rā ka whakamāmā i te whakamāhi hiko i te 20% i ngā pākenga ōtā, i te whakamātautau i ngā taputapu ōtā. Ko te mea e pai ake ana i tēnei, ko te BOPP he iti ake te whānuitanga o te whānuitanga o te hōhā i ngā whakamāhi ātārangi, nō reira he iti ake te hāngā i te hōhā i te wā o te whakamāhi. Ā, ko ngā hōhā hou o te whakamāhi i te whakamāhi i ngā rākau kia māhuhu ake, nō reira he iti ake te whakamāhi i ngā rākau tuatahi. Ko ngā whakamāramatanga katoa nei e mahi tahi ana kia whakamāmā i ngā hauārangi kīrea i tēnā tono i whakamāhinga. Ā, mēnā ko ngā kamupani e whakamāhi ana i ngā pākenga i ngā rākau hiko kia māhuhu ake, pērā i te hiko o te rā, o te hau rānei, ka whakamāmā ake anō te pānga ki te taiao. Nō reira i tēnei wā ko te BOPP he matūtū pū o ngā whakamāhi kia pai ake ngā mahi, ā, kia kore ai ngā pānga ki te ao.

Te Whakamāhinga o te Tāwhai Iti: Te Whakamāhinga Ahukore me te Whakamāhinga o ngā Rākau Iti

Ko ngā kōpae BOPP i te rārangi iti o te pākaro (āhua 9 ki te 30 micron te pākaro) he whakamāhua pai tonu, ā, he iti ake ngā rākau e whakamahinga ana i ngā kōpae mātua. I runga i ngā whakamārama i ngā tikanga whakamātua, kā taea e ngā kaiwhakamahi te whakamahi i ngā kōpae iti ake i te 9 micron, ā, he pai tonu ngā whakamāmā i te wai, i te hauā, i ngā rā whakamāhinga UV e whakamāhinga ana i ngā hua mātua. Ko ngā kōpae iti ake nei he 40% iti ake te pākaro o te pākaro i te kōpae tātai, ā, he mātua tonu ngā kōpae hei whakamāmā i ngā whakamāhinga, hei whakamāmā i ngā whakamāhinga i te whakamāhinga me ngā whakamāhinga. I tēnei, he iti ake te pākaro o te kōpae, he iti ake ngā utu mō te kaiwhakamahi i te huarahi, ā, he whakamāmā tonu i ngā whakamāhinga kōpae katoa. Inā he whakamāmā tonu ngā kōpae iti ake hei whakamāmā i ngā hua, ā, he whakamāmā tonu i te whakamāhinga o ngā rākau, ko ngā kōpae iti ake he whakamāmā tonu hei whakamāmā i ngā hua.

Te Whakamua i te Whakawhitiwhiti: Nga Whirihoranga Whakapaipai BOPP Ka taea te Whakapai Ake me te Whakapaipai

Ko nga Hanganga BOPP Mono-Material e taea ai te Tauhokohoko Miihini

Ko te huri ki nga hanganga BOPP-kotahi-katoa he tohu nui ki te hanga i nga kohinga ki te taiao. Ka whakakorea e ēnei rauemi ngā hoahoa matatini, maha-apa, he mea nui tonu ki ngā kaihanga. He aha te hua? Te tukurua miihini ngawari me te kore e hiahiatia he mahinga wehe motuhake. E kōrero ana mātou mō te whakatau i tētahi raruraru nui i konei mai i te 40% o ngā rauemi whakaranu ka mutu ka whakapoke i runga i te Packaging Digest i te tau kua hipa. Ka taea tonu e ngā kamupene te tiaki i ngā hua mai i te haumākū me te kino hāora mā te whakamahi noa i te BOPP, nō reira kāore he mea e whakahāwea mai i te kounga, i te mahi rānei. A, no te wā o te tukurua, ka pai ake te āhua o ngā mea. Na te pai ake o nga punaha kohinga puta noa i Uropi me Amerika ki te Raki, ko te nuinga o nga waahi kei te kite i nga reanga reanga 80% mo enei kohinga rauemi kotahi inaianei.

Ko nga momo BOPP Compostable kua whakamanahia (hei tauira, nga Kiriata PLA-Hau)

I te wā e iti ana ngā kōwhiringa tukurua, ka riro ngā kiriata BOPP whakamana e taea te whakangao hei tino kaiwhakawhiwhi i te mutunga o to rātau huringa ora. Ko ngā putanga ranunga PLA e paahitia ana e ngā whakamātautau ā-ao pēnei i te paerewa TÜV Austria OK Compost INDUSTRIAL. Ka pakaru katoa i roto i te 12 wiki mēnā ka tukuna ki ngā tipu whakangao tika, engari ka pupuri tonu i ngā āhuatanga pai katoa o te BOPP noa iho i runga i te āhua o te whakahaere i te wā o te hanga. He aha te mea e tino kitea ai ēnei kiriata? He tino pai te ātete ki te hinu me te ngako, he mea nui ki ngā tono mō te tākai kai. E whakaatu ana ngā rangahau ka whakaitihia e rātau te ururua o te rerenga ki te rua hautoru ina whakaritea ki ngā rākau rākau tuku iho. Kua tīmata ngā kaiwhakanao ingoa nui ki te hanga i ngā kōwhiringa pūngoi e mahi pai ana ina tae mai ki te taatiraa me te tā hei rauemi tawhito i runga i te pūngao kōhao.

Te Pānga Taiao-Tino-Tino: Me pēhea te BOPP e whakataurite ana ki ngā PET me ngā PVC Laminates

I te whakamātautau i te taumata o te whakamāhi i ngā rākau whakamātua, ka kitea ngā whai hua mātua o te BOPP. I te whakamātautau i tēnei ki ngā kōpae PET me PVC, ka whakaatu te BOPP i ngā whakamāhi i te wā o te ora he iti ake nui. Ko ngā whakamāhi i te hāora i te wā o te hanganga o ngā kōpae PVC he 40% ake i te BOPP i runga i te whakamāhi i te hāora o te whakamāhi i te kōrere, ā, ko te PET he 25% ake ngā whakamāhi i te hāora i te wā o te hanganga (Rangahau i te Whaihua o ngā Pōlymē, 2023).

He pai hoki te BOPP i ngā āhuatanga o te mutunga o te wā o te whakamāhi:

• Te whakamāhi anō: Ka mau tonu te BOPP i tōna āhua i ngā rere o te whakamāhi anō āhua, rānei, ākine, kāore he rere o te whakamāhi anō āhua mo te PVC, ā, i te whakamāhi i te ahi ka whakawhitinga ngā dioxin kino
• Te whakamāhi i ngā rākau: Ko ngā kōpae BOPP iti te pākaha, ā, e whakamāhi ana i ngā āhua rite ki ngā kōpae PET iti ake, ā, he iti ake te whakamāhi i ngā rākau matua i te 30%
• Te whaiwhai o te rere pū, ā, he rere pū: Ko ngā whakamāhi o ngā whakamāhi BOPP kia kotahi te rākau e whakamāhi ana i te whakamāhi o ngā kōpae PET, ā, e whakamāhi ana i te whakamāhi o ngā kōpae PET

I tēnei whakamātautau ā-ōrite i te tau 2023 mō te Whakamātautau o te Hāngā Ora, kua kitea ko ngā papa o BOPP i whakamāmā i ngā whakawhitinga o te hāngā o te hokohoko umi ake o ngā hāngā o PET, nā te iti ake o te wāhanga o te wāhanga o te hokohoko me ngā hāngā o te whakamāmā i te whakamāhi i te hiko.

Ngā raraunga kua kohia mai i ngā whakamātautau ā-pūrākau mō te oranga o ngā pōlymēr (2021–2023)

Ko tēnei pātaka whakamātautau e whakakaha ana i te BOPP hei whirinaki pai rawa atu i te taiao hei whirinaki mō te whakamāhi, e whakamāhi ana i te whakamāhi pai hoki i te whakamāhi pai o te taiao i te hāngā katoa.

Te Whakamāhi i te Auāhutanga: Ngā Whakamāhi Pūmanawa o ngā Whakamāhi o te Lamination o BOPP e whakamāhi ana i te taiao

Te Tauākī mō te Pakihi Kai: Te Whakakaha i te Wā o te Whakamāhi, ā, te Whakamāmā i ngā raraunga

Kei te huri ngā rongoā whakairo taiao BOPP i te āhua o te tiaki i ngā kai mā ngā kiriata whakarewa tino angiangi e 9 ki te 30 microns te matotoru. Ka hanga ēnei kiriata i ngā arai tino nui ki te hāora, te makuku, me ngā hihi UV kino. Ka roa ake te 40% o ngā hua i runga i ngā papa ina takaihia i tēnei ara, ko te tikanga he iti ake te kai e kino ana i mua i te taenga atu ki ngā papa toa, ki ngā tēpu kaihoko rānei puta noa i te mekameka tuku katoa. I tua atu, he iti rawa te taumaha o ēnei rauemi, ā, e 35% te iti o te kirihou e whakamahia ana i ia tākai, i te mea he iti ake i ngā papa papanga noa. Ko te mea e tino kitea ana tēnei huarahi ko te pai o te whakakotahi i te tiaki o te hua ki te whai i te whakaaro o te ohanga porohita. Ka kite ngā kamupene i ngā moni moni moni tūturu i runga i ō rātou raina o raro i te wā kotahi me te whakaiti i te ururua. He aha te hua whakamutunga? Ka whiwhi ngā kaihoko i ngā taonga hou, kāore i te nui ake te tākai e hiahiatia ana e ngā tikanga tuku iho.

Ngā Pātai e Patai Pūnoa Ana

He aha te BOPP, he aha hoki i kiia ai he taiao?

Ko te BOPP he pāpātanga mō te Biaxially Oriented Polypropylene, ā, he rārangi o ngā kōpae pōlymēr e mōhiotia ana i tōna whakamātautau i te hiko me tōna whakamātau i te whakamātau. He kaiwhakamātau ake i te taiao nā tōna iti i te whakamātautau i te kāpāri karabōn, te whakamātautau pai o ngā rākau, me tōna wāhi ki te whakamātau i te whakamātau.

He aha te whāinga o te BOPP i te whakamātautau i te pānga o te taiao i ngā PET me ngā PVC?

Ko te BOPP he iti ake ngā whakamātautau o te wā o te ora i te whakamātautau i ngā PET me ngā PVC. I tēnei hoki, he pai ake ngā whakamātautau o te whakamātau, ā, he māmā ake te whakamātau i ngā rākau.

Mā te whakamātau, he whakamātau, he whakamātau rānei ngā kōpae BOPP?

Āe, mā te whakamātau ngā kōpae BOPP i tō rātou hanga kotahi. I tēnei hoki, he āhua o ngā kōpae BOPP i tāwhai i te PLA, he whakamātau ā-ture.
