Umkhakha womhlaba wonke wezinto ze-polythene ubhekene noshintsho olusheshayo njengoba abakhiqizi, abacwaningi, nabalawuli besabela ezidingweni zemakethe eziguqukayo kanye nezingcindezi zemvelo. Lesi sihloko sihlanganisa izibuyekezo eziphathiswe igunya, ukuqonda kwezobuchwepheshe, kanye nemiphumela yebhizinisi ukusiza izinkampani ukuthi zihlale zinolwazi mayelana nempumelelo kubuchwepheshe be-polythene kanye nemikhuba esimeme. Ihlanganisa umehluko phakathi kwe-low density polyethylene ne-high density polyethylene, intuthuko ezinhlelweni ze-recycled polyethylene ne-expanded polyethylene, kanye nezinga lemithetho elithinta izinto ezithunyelwayo kanye nokuklama imikhiqizo.

Izimemezelo zakamuva zenkampani zigcizelela ukwanda kokutshalwa kwezimali kwingqalasizinda yokugaywa kabusha kanye nesayensi yezinto ukuze kuthuthukiswe impilo yezinto ze-polythene. Abadlali abaningi bemboni baye bandisa imizamo yokugaywa kabusha ngomshini nangamakhemikhali ukuze bakhiqize udoti wangemuva komthengi ube yi-polyethylene egaywe kabusha esezingeni eliphezulu efanelekayo ukupakisha nezingxenye zezimboni. Lezi zinhlelo azigcini nje ngokushukunyiswa yimigomo yezemvelo kodwa futhi zishukunyiswa izikhuthazo zezentengiselwano ukunciphisa izindleko zezinto ezingavuthiwe kanye nokuqinisekisa ukuzinza kokuhlinzekwa. Ezebhizinisi, ukuhlala unolwazi ngezitatimende zabahlinzeki kungaveza amathuba okuthola ama-resin agaywe kabusha noma ukuthuthukisa ndawonye imigqa yemikhiqizo eyindilinga.

Izindaba ezintsha ezithinta ubuchwepheshe zivame ukuba nezindaba ngezi-foam ze-polyethylene (EPE) ezandisiwe ezisetshenziselwa ukugcwalisa nokufakelwa, lapho abakhiqizi belungisa khona ubuningi kanye nesakhiwo samaseli ukuze balethe imikhiqizo elula, eqinile. Izinkampani ziphinde zibonise imiqondo yokupakisha ebolayo eyenza izithako ezihlanjululwayo zihlanganiswe nezakhiwo ezijwayelekile ze-polythene ukuze kusheshe ukubola kwemvelo ngaphansi kwezimo ezilawulwayo. Ngenkathi izixazululo ezinjalo ezixubile zingathuthukisa ukusebenza ekupheleni kwempilo, abakhiqizi kufanele bahlole ngokucophelela ukwamukelwa kwemithetho kanye nokuqinisekiswa ukuze bagweme ubungozi bokuhlaza okotshani. Abasebenzisi bokuqala bavame ukutshala imali kumamodeli wokuhlola kanye nokuqinisekiswa ngabantu besithathu ukuze babonise ukuthobela.

Umehluko phakathi kwe-low density polyethylene (LDPE) ne-high density polyethylene (HDPE) uhlala ubalulekile ekukhetheni izinto. I-LDPE inikeza ukuguquguquka okungcono, ukucaca, nokukwazi ukubopha, okwenza kube yinto ekhethwayo kumafilimu, izikhwama, nokupakisha okuguquguqukayo. Ngokuphambene, i-HDPE inikeza amandla aphezulu okudonsa, ukuqina, nokumelana namakhemikhali, okwenza kube kuhle ezitsheni eziqinile, imibhobho, nezingxenye ezakhiweyo. Ukuqonda lemihluko eyisisekelo kusiza abaklami bemikhiqizo ukuthi bahambisane nezidingo zokusebenza—njengokuvimbela izinto, ukumelana nokushisa, noma ukusebenziseka kabusha—nomndeni ofanele we-resin. Ukwenza kahle amafomula kuvame ukubandakanya ukuhlanganisa izingxenye ze-HDPE ne-LDPE noma ukwengeza izithako ezisebenzayo ukuze kulungiswe ukusebenza.

Ngokombono wokucubungula, i-LDPE ngokuvamile idinga izinga lokushisa eliphansi lokuncibilika kanye nezinye izindlela zokukhipha kunama-HDPE, futhi lokhu kuthinta ukukhethwa kwemishini nokusetshenziswa kwamandla. Ezinkampanini ezihlola ukushintsha phakathi kwezinhlobo ze-resin, ukugijima kwezivivinyo kanye nokuhlolwa kwe-rheological kubalulekile ukubikezela ukuziphatha lapho kwandiswa. Ngaphezu kwalokho, ukuhambisana kwezinhlobo ze-polyethylene ezisetshenziswe kabusha ne-LDPE noma i-HDPE entsha kufanele kuhlolwe ukuqinisekisa ukusebenza ekugcineni kanye nokuthobela imithetho, ikakhulukazi ezinhlelweni zokuthintana nokudla.
