(1) intambo ye-polyethylene isetshenziswa kakhulu ekudobeni, imvamisa ihambisana nenethi yokudoba, ayifakwa ngokugcwele kwezinye izimboni.
(2) Akuvunyelwe ngokuphelele ukuthintana ngqo nezinto ezicijile, njengombese, isikele uma ungafuni ukuthi inqanyulwe.
(3) Intambo ye-polyethylene inezici ezinhle ze-asidi nezici zokumelana ne-alkali.Kodwa sicela ungavumeli intambo ukuthintana ne-asidi, i-alkali nokunye okulimazayo isikhathi eside.
(4) Intambo ye-polyethylene enamandla amakhulu, ukumelana nokugqwala, izinga lokushisa eliphansi, umswakama kanye nokusebenza kahle.
(5) Kufanele ihlole ngokucophelela ngaphambi kokusebenzisa intambo ye-polyethylene lapho ingaphezulu lomfaniswano lingagqoki ngaphezu kwama-30% ububanzi, lingabi ngaphezu kuka-10% elinengxenye ephambanayo yobubanzi bokulimala kokuthinta kwendawo, ingasetshenziswa ngokuvumelana ububanzi noma ukusika okuncane.Njengokulimala kokuthintwa kwendawo kanye nokugqwala kwendawo kubi kakhulu, kungasikwa engxenyeni eyonakele yepulaki.
