1. Ngenxa yokuthi ubhiya uqukethe izithako eziphilayo ezinjengotshwala, kanti ipulasitiki esemabhodleleni epulasitiki ingeyezinto eziphilayo, lezi zinto eziphilayo ziyingozi emzimbeni womuntu.Ngokomgomo wokuhambisana okuningiliziwe, lezi zinto eziphilayo zizoncibilika kubhiya.Izinto eziphilayo ezinobuthi zingena emzimbeni, ngaleyo ndlela zibangele ukulimala emzimbeni womuntu, ngakho ubhiya awupakishwa emabhodleleni epulasitiki.
2. Amabhodlela engilazi anezinzuzo zezakhiwo ezinhle zokuvimbela igesi, ukuphila isikhathi eside kwesitoreji, ukukhanya okuhle, nokugaywa kabusha okulula, kodwa kunezinkinga ezifana nokusetshenziswa okuphezulu kwamandla ekukhiqizeni, ukuba nzima, nokuqhuma kalula nokulimala.
Muva nje, ukuthuthukiswa kanye nocwaningo lwamabhodlela e-PET anezithiyo eziphezulu afakwe ubhiya njengoba okuhlosiwe okuyinhloko sekuphenduke indawo eshisayo embonini, futhi inqubekelaphambili enkulu yenziwe ngemuva kwesikhathi eside somsebenzi obanzi wocwaningo.Ubhiya uzwela kakhulu ekukhanyeni nakwi-oxygen, futhi impilo yeshalofu ngokuvamile ifinyelela izinsuku ezingu-120.I-oxygen permeability yebhodlela likabhiya iyadingeka ukuthi ingabi ngaphezu kwe-1 × 10-6g ezinsukwini ezingu-120, futhi ukulahlekelwa kwe-CO2 akukho ngaphezu kuka-5%.
Le mfuneko izikhathi ezingu-2 ~ 5 zempahla yesithiyo yebhodlela le-PET elihlanzekile;Ngaphezu kwalokho, ezinye izinkampani ezikhiqiza utshwala zisebenzisa indlela yokuphuza ubhiya, edinga ukuthi izinga lokushisa eliphakeme lifinyelele ku-298 ℃, kuyilapho amandla, ukumelana nokushisa, isithiyo segesi sebhodlela le-PET elihlanzekile Izakhiwo azifinyeleleki ezidingweni zamabhodlela kabhiya, ngakho-ke, abantu umjaho wokucwaninga nokuthuthukisa izinto ezintsha nezinqubo ezintsha zezithiyo nezithuthukisi ezihlukahlukene.
Njengamanje, ubuchwepheshe bokushintsha amabhodlela engilazi namakani ensimbi kabhiya ngamabhodlela e-polyester sebukhulile, futhi inqubo yokuthengisa isiqalile.Ngokwesibikezelo sikamagazini i-Modern Plastics, eminyakeni emi-3 kuya kweyi-10 ezayo, u-1% kuya ku-5% wobhiya womhlaba uzoguqulwa ube yi-PET bottle package.
