Mai i te tau 2020, kua uru ngā wheketere polyethylene ā-rohe ki tētahi huringa whānui pokapū, ā, kua tere te pikinga o te kaha whakaputa ā-tau o te PE ā-rohe, me te tere tipu ā-tau toharite neke atu i te 10%. Kua tere te pikinga o te hanga polyethylene ā-rohe, me te whakakotahitanga hua nui me te whakataetae nui i roto i te mākete polyethylene. Ahakoa kua whakaatuhia hoki te ia tipu o te tono mō te polyethylene i ngā tau tata nei, kāore te tipu o te tono i tere rite ki te tere tipu o te tuku. Mai i te tau 2017 ki te 2020, ko te kaha whakaputa hou o te polyethylene ā-rohe i aro nui ki ngā momo ngaohiko iti me ngā momo raina, ā, kāore he taputapu ngaohiko teitei i whakamahia ki Haina, i hua ake ai he mahi kaha i roto i te mākete ngaohiko teitei. I te tau 2020, i te mea ka piki haere te rerekētanga utu i waenga i te LDPE me te LLDPE, ka piki ake te aro ki ngā hua LDPE. I whakahaerehia te wāhanga whakaputa tahi EVA me te wāhanga LDPE Petrochemical Zhejiang i te tau 2022, me te kaha whakaputa pehanga teitei ā-rohe o te 3.335 miriona tana i te rā o mua.
I te tau 2023, i whakaatuhia e te mākete pēhanga teitei he ia hurihuri me te heke. Hei tauira, ko te mākete o Te Tai Tokerau o Haina, ko te utu pēhanga teitei toharite mai i Hānuere ki Mei he 8853 yuan/tana, he hekenga nui i ia tau o te 24.24%. I te wā tino nui o te tono mō te kiriata kirihou i te hauwhā tuatahi, he kaha ngā utu raina. Ko te utu toharite raina mai i Hānuere ki Āperira he 8273, he hekenga i ia tau o te 7.42%. I tino whakawhāitihia te rerekētanga utu i waenga i te ngaohiko teitei me te raina. I te 23 o Mei, ko te raina matua ā-rohe i roto i te mākete o Te Tai Tokerau o Haina he 7700-7950 yuan/tana, ko te kiriata noa pehanga teitei ā-rohe i pūrongohia i te 8000-8200 yuan/tana. Ko te rerekētanga utu i waenga i te ngaohiko teitei me te raina he 250-300 yuan/tana.
I te nuinga o te wā, nā te whānui haere tonu o te kaha whakaputa polyethylene ā-whare me te piki haere haere o te tuku ā-whare, kua kaha ake te raruraru o te tuku nui rawa atu i roto i te umanga polyethylene. Ahakoa he paku teitei ake te utu whakaputa mō te ngaohiko teitei i te raina, nā te mea ka taea te whakakapi i te raina me te metallocene i roto i ētahi wāhi whakaputa, he uaua ki te tautoko i ngā utu teitei me ngā hua nui i roto i te mākete polyethylene ngoikore o nāianei, ā, kua tino whaiti te rerekētanga utu i waenga i te ngaohiko teitei me te raina.
