Ka tsoelopele ea theknoloji le ho phahama ha lipapali tsa kantle,litafole tse phuthang tsa polasetikibutle-butle li fihlile mahlong a batho.E hapile kamohelo ea batho bakeng sa molumo oa eona o monyane haholo, boima bo bobebe le tšebeliso e bonolo kamora ho mena.Tafole e phuthang e entsoe ka phanele le foreimi.Kajeno ke tla hlahisa thepa ea tafole e phuthang.
Polyethylene e phahameng haholo (HDPE), phofo e tšoeu kapa sehlahisoa sa granular.Ha e na chefo, e sa latsoeheng, e kristale ea 80% ho isa ho 90%, ntlha e nolofatsang ea 125 ho ea ho 135 ° C, mocheso oa tšebeletso ho fihlela ho 100 ° C;
ho thatafala, matla a tsitsitseng le ho qhekella ho molemo ho feta polyethylene e tlaase;

botsitso bo botle ba lik'hemik'hale, bo ke keng ba qhibiliha ka har'a li-solvents leha e le life ka mocheso oa kamore, kutu e hanyetsanang le li-acids, alkalis le matsoai a sa tšoaneng;
filimi e na le permeability e tlaase ho mouoane oa metsi le moea, le ho monya metsi Ho tlaase;
khanyetso e mpe ea botsofali, khanyetso ea khatello ea tikoloho ha e ntle joalo ka polyethylene e tlase-tlaase, haholo-holo oxidation ea mocheso e tla fokotsa ts'ebetso ea eona,
kahoo li-antioxidants le li-absorber tsa ultraviolet li tlameha ho kenngoa ho resin ho ntlafatsa khaello ena.
Filimi e phahameng ea polyethylene e na le mocheso o fokolang oa mocheso tlas'a khatello ea kelello, kahoo tlhokomelo e lokela ho nkoa ha u e sebelisa.
Lekholong lena la lilemo, tsoelo-pele ea phetoho e etsahetse tšimong ea liphaephe, ke hore, "ho nkela tšepe sebaka ka polasetiki".Ka tsoelo-pele e potlakileng ea saense le thekenoloji ea thepa ea polymer, ho teba ha nts'etsopele le tšebeliso ea liphaephe tsa polasetiki, le ntlafatso e tsoelang pele ea theknoloji ea tlhahiso, liphaephe tsa polasetiki li bontšitse ka botlalo ts'ebetso ea tsona e babatsehang.
Kajeno, liphaephe tsa polasetiki ha li sa nkoa ka phoso e le "liphaephe tse theko e tlaase" bakeng sa lipeipi tsa tšepe.Phetohelong ena, liphaephe tsa polyethylene li ratoa 'me li ntse li khanya ka ho eketsehileng.Li sebelisoa haholo phetisong ea khase, phepelo ea metsi, phallo ea likhoerekhoere, nosetso ea temo, lipalangoang tse ntle tse tiileng merafong, hammoho le masimong a oli, lik'hemik'hale, poso le likhokahano tsa mehala, joalo-joalo, haholo-holo masimong a joalo ka ha a ntse a sebelisoa haholo. sepalangoang sa khase.
