Kusukela ngo-2020, izitshalo ze-polyethylene zasekhaya zingene emjikelezweni wokwanda ophakathi, futhi amandla okukhiqiza wonyaka we-PE yasekhaya akhuphuke ngokushesha, ngesilinganiso sokukhula sonyaka esimaphakathi esingaphezu kuka-10%. Ukukhiqizwa kwe-polyethylene ekhiqizwe ekhaya kukhuphuke ngokushesha, ngokuhlanganiswa okukhulu komkhiqizo kanye nokuncintisana okukhulu emakethe ye-polyethylene. Nakuba isidingo se-polyethylene sibonise ukuthambekela kokukhula eminyakeni yamuva nje, ukukhula kwesidingo akukaze kube ngokushesha njengesilinganiso sokukhula kokuhlinzekwa. Kusukela ngo-2017 kuya ku-2020, amandla okukhiqiza amasha e-polyethylene yasekhaya agxile kakhulu ezinhlotsheni ezinama-voltage aphansi kanye neziqondile, futhi bekungekho madivayisi ane-voltage ephezulu asetshenziswa eShayina, okwaholela ekusebenzeni okuqinile emakethe ene-voltage ephezulu. Ngo-2020, njengoba umehluko wentengo phakathi kwe-LDPE ne-LLDPE wanda kancane kancane, ukunakwa kwemikhiqizo ye-LDPE kwanda. Iyunithi yokukhiqiza ye-EVA kanye neyunithi ye-Zhejiang Petrochemical LDPE kwaqala ukusebenza ngo-2022, ngomthamo wokukhiqiza wasekhaya onengcindezi ephezulu wamathani ayizigidi ezingu-3.335 kusukela ngosuku olwedlule.
Ngo-2023, imakethe yokucindezela okuphezulu ibonise ukuthambekela okushintshashintshayo nokwehla. Uma sibheka imakethe yaseNyakatho China njengesibonelo, intengo ephakathi yokucindezela okuphezulu kusukela ngoJanuwari kuya kuMeyi yayingu-8853 yuan/ton, ukwehla okukhulu konyaka nonyaka okungu-24.24%. Esikhathini esiphezulu sokufunwa kwefilimu yepulasitiki kwikota yokuqala, amanani aqondile ayeqinile. Intengo ephakathi kusukela ngoJanuwari kuya ku-Ephreli yayingu-8273, ukwehla konyaka nonyaka okungu-7.42%. Umehluko wentengo phakathi kwamandla aphezulu kanye namanani aqondile wancishiswa kakhulu. Kusukela ngoMeyi 23, amandla amakhulu angaphakathi emakethe yaseNyakatho China ayengu-7700-7950 yuan/ton, kuyilapho amandla amakhulu angaphakathi angaphakathi angaphakathi abikwa ku-8000-8200 yuan/ton. Umehluko wentengo phakathi kwamandla aphezulu kanye namanani aqondile wawungu-250-300 yuan/ton.
Sekukonke, ngokwandiswa okuqhubekayo kwamandla okukhiqiza i-polyethylene yasekhaya kanye nokwanda kancane kancane kokuhlinzekwa kwekhaya, inkinga yokuphakelwa ngokweqile embonini ye-polyethylene ikhule kakhulu. Nakuba izindleko zokukhiqiza i-voltage ephezulu ziphakeme kancane kune-linear, ngenxa yokufakwa esikhundleni kwe-linear kanye ne-metallocene kwezinye izindawo zokukhiqiza, kunzima ukusekela amanani aphezulu kanye nenzuzo ephezulu emakethe ye-polyethylene ebuthakathaka yamanje, futhi umehluko wentengo phakathi kwe-voltage ephezulu kanye ne-linear unciphile kakhulu.
