He rauemi takai ngāwari mārama pai rawa atu te kiriata polypropylene whakahāngai rua (he kiriata BOPP te whakarāpopototanga). He painga nui te kiriata polypropylene whakahāngai rua, arā, he kaha ā-tinana, he māmā, he kore paitini, he ātete ki te makuku, he whānui te whānuitanga o te tono, ā, he pumau te mahi. E ai ki ngā whakamahinga rerekē, ka taea te wehewehe i te kiriata polypropylene whakahāngai rua ki te kiriata hiri wera, te kiriata tapanga, te kiriata matte, te kiriata noa me te kiriata pūnga.
He rauemi mata nui te polypropylene mō te kiriata polypropylene e rua ngā taha. He kapia hangai kirihou wera te polypropylene, he tino pai te mahi. He pai ōna painga o te pumau o ngā taha, te ātete wera nui me te pai o te whakamarumaru hiko, ā, he nui te tono i roto i te mara tākai. I te tau 2021, ka eke te putanga polypropylene (PP) o tōku whenua ki te 29.143 miriona tana, he pikinga tau-ki-te-tau o te 10.2%. Nā te nui o ngā rauemi mata, kua tere te whanaketanga o te umanga kiriata polypropylene e rua ngā taha o tōku whenua, ā, kei te piki haere tonu tana putanga. E ai ki ngā raraunga mai i te Tari Tatauranga ā-Motu, ka eke te whakaputanga kiriata polypropylene e rua ngā taha o tōku whenua ki te 4.076 miriona tana i te tau 2021, he pikinga tau-ki-te-tau o te 8.7%.
Ko ngā tikanga whakaputa o te kiriata polypropylene whakahāngai rua ko te tikanga kiriata ngongo me te tikanga kiriata papatahi. Nā te koretake o te kounga me te iti o te whai huatanga o ngā hua i hangaia e te tikanga kiriuhi ngongo, kua āta tangohia e ngā umanga nui. Ka taea te wehewehe i te tikanga kiriata papatahi ki te tikanga totoro rua-axial i te wā kotahi me te tikanga totoro rua-axial i te taahiraa. Ko te tukanga totoro rua-axial taahiraa-i-te-taahiraa koia ēnei: rauemi mata → whakaputa → maka → totoro whakaroa → kuti taha → maimoatanga korona → takai → hurihuri kiriata nui → koroheketanga → haehae → hua oti. I tēnei wā, ko te tikanga totoro rua-axial āta whakamahia e te nuinga o ngā umanga nā ōna painga o te hangarau pakeke, te whai huatanga whakaputa teitei, me te pai mō te whakaputa papatipu.
He whānuitia te whakamahinga o te kiriata polypropylene whakahāngai rua i roto i ngā rauemi tākai pēnei i te kākahu, te kai, te rongoā, te tā, te tupeka me te waipiro. I tēnei wā, kua āta whakakapia ngā kiriata tākai noa pēnei i te polyethylene (PE), te polypropylene (PP), me te polyvinyl chloride (PVC) e te kiriata polypropylene whakahāngai rua. Ko tōku whenua te whenua tākai tuarua nui rawa atu o te ao, ā, kei te tipu haere tonu te tono mō ngā tākai. E ai ki ngā tatauranga mai i te China Packaging Federation, ko te moni whiwhi katoa o ngā umanga kei runga ake i te rahi kua tohua i roto i te umanga tākai o tōku whenua ka eke ki te 1,204.18 piriona yuan i te tau 2021, he pikinga tau-ki-te-tau o te 16.4%. Me te tere o te whanaketanga o te umanga tākai o tōku whenua, ka whai tirohanga whānui te kiriata polypropylene whakahāngai rua hei rauemi tākai nui.
I kī ngā kaitātari ahumahi o Xinsijie, mā te nui o ngā rauemi mata me te pakari o te hangarau whakaputa, he nui te pūmanawa whanaketanga o te umanga kiriata polypropylene e rua-axial o tōku whenua. Mā te tere o te whanaketanga o te umanga tākai ka akiaki i te whānui ake o te mākete kiriata polypropylene e rua-axial o tōku whenua. Mā te hohonu haere o te ariā o te kai matomato, ka whakapai ake ngā kaihoko i ngā whakaritenga kounga o ngā rauemi tākai, ā, ka noho ko te kiriata polypropylene e rua-axial, e penapena ana i te kaha me te pai ki te taiao, hei mea matua o te mākete.
