Ukususela ngo-2020, izityalo ze-polyethylene zasekhaya zingene kumjikelo wokwandiswa okuphakathi, kwaye amandla okuvelisa ngonyaka we-PE yasekhaya anyuke ngokukhawuleza, ngesantya sokukhula sonyaka esiphakathi esingaphezulu kwe-10%. Imveliso ye-polyethylene eveliswe ekhaya inyuke ngokukhawuleza, kunye nokuhlanganiswa okukhulu kwemveliso kunye nokhuphiswano olukhulu kwimarike ye-polyethylene. Nangona imfuno ye-polyethylene ikwabonakalise umkhwa wokukhula kwiminyaka yakutshanje, ukukhula kwemfuno akukhange kube ngokukhawuleza njengesantya sokukhula kobonelelo. Ukususela ngo-2017 ukuya ku-2020, amandla amatsha okuvelisa i-polyethylene yasekhaya agxile kakhulu kwiindidi ze-voltage ephantsi kunye ne-linear, kwaye bekungekho zixhobo ze-voltage ephezulu ezisetyenzisiweyo eTshayina, nto leyo ebangele ukusebenza okuqinileyo kwimarike ye-voltage ephezulu. Ngo-2020, njengoko umahluko wamaxabiso phakathi kwe-LDPE kunye ne-LLDPE usanda kancinci, ingqalelo yeemveliso ze-LDPE yanda. Iyunithi yemveliso ye-EVA kunye neyunithi ye-Zhejiang Petrochemical LDPE zaqaliswa ukusebenza ngo-2022, kunye namandla okuvelisa asekhaya aphezulu eetoni eziyi-3.335 yezigidi ukusukela ngosuku oludlulileyo.
Ngowama-2023, imakethi enoxinzelelo oluphezulu ibonakalise umkhwa otshintshatshintshayo nowokwehla. Xa sithatha imakethi yaseMntla China njengomzekelo, ixabiso eliphakathi loxinzelelo oluphezulu ukusuka ngoJanuwari ukuya kuMeyi yayiyi-8853 yuan/ton, ukwehla okukhulu konyaka nonyaka kwe-24.24%. Kwixesha eliphezulu lemfuno yefilimu yeplastiki kwikota yokuqala, amaxabiso alinganayo ayenamandla. Ixabiso eliphakathi eliphakathi ukusuka ngoJanuwari ukuya ku-Epreli yayiyi-8273, ukwehla konyaka nonyaka kwe-7.42%. Umahluko wamaxabiso phakathi kombane ophezulu kunye nomgca wawuncitshisiwe kakhulu. Ukusukela ngoMeyi 23, i-linear mainstream yasekhaya kwimakethi yaseMntla China yayiyi-7700-7950 yuan/ton, ngelixa i-high-pressure ordinary film mainstream yasekhaya ibikwe kwi-8000-8200 yuan/ton. Umahluko wamaxabiso phakathi kombane ophezulu kunye nomgca wawuyi-250-300 yuan/ton.
Lilonke, ngenxa yokwanda okuqhubekayo kwamandla emveliso ye-polyethylene yasekhaya kunye nokwanda kancinci kobonelelo lwasekhaya, ingxaki yokubonelela ngokugqithisileyo kwishishini le-polyethylene iye yanda. Nangona iindleko zemveliso ye-voltage ephezulu ziphezulu kancinci kune-linear, ngenxa yokutshintshwa kwe-linear kunye ne-metallocene kwezinye iindawo zemveliso, kunzima ukuxhasa amaxabiso aphezulu kunye nenzuzo ephezulu kwimarike ye-polyethylene ebuthathaka yangoku, kwaye umahluko wamaxabiso phakathi kwe-voltage ephezulu kunye ne-linear uye wancipha kakhulu.
