PE yog cov ntawv luv ntawm polyethylene ntawm qhov kub thiab txias tsis kam. Feem ntau, daim ntawv thov ntau yam ntawm PE yeeb nkab rau cov kav dej yog qis dua 40 ℃, yog li nws tsis tuaj yeem siv rau cov kav dej kub xa mus. PE yeeb nkab yog ib hom siab crystallinity, uas tsis yog-polar thermoplastic resin. Cov tsos ntawm thawj HDPE yog milky dawb thiab translucent rau qee yam hauv ntu nyias. PE muaj kev tiv thaiv zoo rau feem ntau cov tshuaj hauv tsev thiab kev lag luam.
