Kuyambira 2020, zomera zoweta za polyethylene zalowa m'malo okulirakulira, ndipo mphamvu yopanga pachaka ya PE yoweta yakula kwambiri, ndikukula kwapakati pachaka kupitirira 10%. Kupanga polyethylene opangidwa m'nyumba kwakula mofulumira, ndi homogenization yoopsa ya mankhwala ndi mpikisano woopsa pamsika wa polyethylene. Ngakhale kufunikira kwa polyethylene kwawonetsanso kukula m'zaka zaposachedwa, kukula kwa kufunikira sikunakhale kofulumira ngati kuchuluka kwazomwe zimaperekedwa. Kuchokera mu 2017 mpaka 2020, mphamvu yatsopano yopangira polyethylene yapakhomo makamaka imayang'ana mitundu yotsika kwambiri komanso yozungulira, ndipo panalibe zipangizo zamagetsi zomwe zimagwiritsidwa ntchito ku China, zomwe zinachititsa kuti msika ukhale wolimba kwambiri. Mu 2020, kusiyana kwamitengo pakati pa LDPE ndi LLDPE kukukula pang'onopang'ono, chidwi cha zinthu za LDPE chinakula. EVA co Production unit ndi Zhejiang Petrochemical LDPE unit zidayamba kugwira ntchito mu 2022, zokhala ndi mphamvu zopanga zapakhomo zokwana matani 3.335 miliyoni monga tsiku lapitalo.
Mu 2023, msika wopanikizika kwambiri udawonetsa kusinthasintha komanso kutsika. Kutengera msika waku North China mwachitsanzo, mtengo wapakati wokwera kwambiri kuyambira Januware mpaka Meyi unali 8853 yuan/tani, kutsika kwakukulu pachaka kwa 24.24%. M'nyengo yapamwamba ya kufunikira kwa filimu ya pulasitiki m'gawo loyamba, mitengo ya mzere inali yamphamvu kwambiri. Mtengo wapakati wapakati kuyambira Januware mpaka Epulo unali 8273, kutsika kwapachaka kwa 7.42%. Kusiyana kwamitengo pakati pa voteji yayikulu ndi liniya kunachepetsedwa kwambiri. Pofika pa Meyi 23, msika wamsika waku North China unali 7700-7950 yuan/ton, pomwe mafilimu wamba omwe ali ndi vuto lalikulu adanenedwa kuti ndi 8000-8200 yuan/ton. Kusiyana kwamitengo pakati pa voteji yayikulu ndi liniya kunali 250-300 yuan/tani.
Cacikulu, ndi kukulitsa mosalekeza wa mphamvu zoweta polyethylene kupanga ndi kuwonjezeka pang'onopang'ono wa zoweta, vuto la oversupply mu makampani polyethylene chakula. Ngakhale mtengo kupanga kwa voteji mkulu ndi apamwamba pang'ono kuposa liniya, chifukwa substitutability wa liniya ndi metallocene m'madera kupanga, n'kovuta kuthandizira mitengo mkulu ndi phindu lalikulu panopa ofooka polyethylene msika, ndi kusiyana mtengo pakati voteji mkulu. ndipo linear yachepa kwambiri.
