Izinto ze-polythene, ezaziwa ngokujwayelekile njenge-polyethylene emibhalweni yezobuchwepheshe, zimelela umndeni obanzi wezinto ze-thermoplastic polymers ezisetshenziswa kakhulu ezimbonini. Le mbono ibonisa lokho abakhiqizi namathimba okuthenga okudingeka bakwazi mayelana ne-chemistry, izinga, kanye nokuma kwemakethe kwezinto ze-polythene. Izinto ze-polythene zihlukaniswa zibe phakathi kwe-polyethylene enezinga eliphansi, ethambile, ne-polyethylene enezinga eliphezulu, eqinile, futhi zifaka phakathi izinhlobo ezakhiwe njenge-polyethylene ebanzi yokuthambisa nokufaka. Ukuqonda umehluko phakathi kwalezi zinga kusiza amabhizinisi ukukhetha i-resin efanele yokupakisha, izingxenye ezimolded, noma izicelo ze-filimu. Kubakhiqizi abasebenza nabahlinzeki, ukusho kahle izici ezifana ne-melt index, amandla okudonsa, kanye nedensity kunciphisa umsebenzi ophindwayo futhi kuthuthukisa ukusebenza komkhiqizo. Izinkampani eziningi zokuhweba nabakhiqizi manje zishicilela amakhasi edatha anemininingwane ukuze zisize abathengi baqhathanise izinketho futhi baqinisekise ukuthi into ethile ye-polythene ihlangabezana nezidingo zomthetho nezidingo ezihambisana nezicelo.

I-Polyethylene enezinga eziphansi (LDPE) kanye ne-polyethylene enezinga eliphezulu (HDPE) yizigaba ezimbili eziphambili zokuhweba zezakhiwo ze-polythene, ngayinye ihlelwe ukuze isetshenziswe ngezindlela ezahlukene. I-LDPE inezakhiwo ze-polymer ezihlukanisiwe ezihlinzeka ngokuqina, ukuvuleka, nokusebenza kahle ezishisayo, okwenza kube kuhle kakhulu kumafilimu, ukupakisha okuguquguqukayo, kanye nezinye izifutho zokuphuma. I-High density polyethylene inezakhiwo ezilandelanayo, okuholela ekwandeni kokuphakama kokudonsa, ukumelana nezinto ezikhemikhali, nokuqinisa; i-HDPE isetshenziswa kabanzi ezimpahleni eziqinile, emaphaketheni, nasezikhwama ezifana namabhodlela e-polyethylene. Ngaphezu kwe-LDPE ne-HDPE, abakhiqizi bakhiqiza amazinga akhethekile afaka phakathi ama-foams e-polyethylene akhuphukayo ukuze akwazi ukumunca ukushayisana kanye nezinhlobo ezixhunywe ukuze kuthuthukiswe izakhiwo zokushisa. Ukukhetha uhlobo olufanele kudinga ukubuyekezwa kokucindezela kokusebenza, ukuvezwa kwemvelo, nezindlela zokucubungula ezifana nokuphuma komoya, ukucindezela, noma ukuphuma kwefilimu. Kubantu abahweba ngezinto zokwakha, ukusebenza nabahlinzeki abanamava abangahambisana nezinga le-resin nezinsiza zokucubungula kunciphisa amaphutha ekukhiqizeni futhi kuthuthukisa umkhiqizo.

Izinto ze-polythene zinikeza ukuhlanganiswa kwezici zokusebenza ezichaza ubukhona bazo ekwenziweni nasekupakisheni. Ukuhlala kwazo isikhathi eside nokumelana nemvula, amakhemikhali, nokushayisana kwenza i-polythene ibe ukukhetha okungabizi kwezingxenye ezihlala isikhathi eside nezokupakisha ezivikela. Ukuhluka kuyinzuzo enkulu enye: izixazululo nezithako zivumela ukulungiswa kokungaguquguquki, ukumelana ne-UV, umbala, nokumelana nomlilo ukuze kuhlangabezane nezidingo zomkhiqizo ezithile ngenkathi kugcinwa ukucubungula kahle. Ukusebenza kahle kwezindleko kuvela kumathuba okwakha asekelwe, ukutholakala okubanzi kwezinto zokwakha, kanye nezindlela zokuphinda zisetshenziswe ezingeni eliningi; lokhu kuholela ezindlekweni ezincintisanayo zokufika kwamabhizinisi ngezinga.
