I te tau kua hipa (2024), nā te whanaketanga o ngā ahumahi pēnei i ngā motuka me te takai, kua piki haere tonu te ahumahi polyolefin i ngā rohe o Āhia me te Moana-nui-a-Kiwa me te Waenganui Rawhiti. Kua piki ake te hiahia mō ngā kaihoko nucleating.

(He aha te matū whakatupu?)

Hei tauira, ko te pikinga ā-tau o te hiahia mō ngā matū whakatipu matū i roto i ngā tau e 7 kua pahure ake nei kei te 10%. Ahakoa kua paku heke te tere tipu, he nui tonu te pūmanawa mō te tipu ā-muri.

I tēnei tau, e matapaetia ana ka eke ngā kaihanga Hainamana ki te 1/3 o te wahanga mākete o te rohe.

Ki te whakatauritea ki ngā kaiwhakataetae o Te Hononga o Amerika me Hapani, ahakoa he tauhou ngā kaiwhakarato Hainamana, he painga utu kei a rātou, e wero ana i te kaha hou ki roto i te mākete kaihoko whakatipu katoa.

Tō mātoungā kaihoko whakatupukua kaweakehia ki ngā whenua tata maha, tae atu ki ngā whenua o Türkiye me te Moana-a-Kiwa, ā, he rite tonu te kounga ki ngā puna tuku iho o Amerika me Hapanihi. He katoa ā mātou hua, ā, he pai mō ngā rauemi pēnei i te PE me te PP, e whakarato ana i ngā kōwhiringa maha atu ki ngā kiritaki.
