Le mveliso ithatha ulwakhiwo olunemigangatho emininzi, kunye nokusebenza okunamandla okuthintelwa okuphezulu. Izinto eziphathekayo zomgangatho ophakathi yi-aluminium foil, enobungqina bomswakama, ubungqina bokukhanya, kunye ne-insulation efanelekileyo yamanzi, umsebenzi wokufakelwa kwe-oxygen. Enye into embindini wengxowa yinayiloni. Inamandla aphezulu okuqina, kodwa ikwanazo ukumelana nobushushu, ukumelana nokubanda, ukuxhathisa kwe-oyile kunye nokumelana ne-solvent ye-organic, ukumelana nokunxiba, ukuxhathisa okugqwesileyo kokugqobhoza.
