Izikhwama zokufaka amaswidi zivame ukusetshenziselwa ukuthwala amaswidi anambitheka ehlukahlukene kanye nokuma futhi ziwagcine ehlanzekile futhi eqinile. Ngokuvamile zenziwe ngezinto ezihlukahlukene, njenge-PE, PET, CPP, ukuvikela amaswidi ekungcoleni nasekuwohlokeni. Izikhwama zokufaka uswidi zivame ukuphrintwa ngamaphethini ahlukahlukene akhangayo, amaphethini namalogo ukuze adonse ukunaka kwamakhasimende. Isikhwama sokupakisha uswidi siphinde sakhiwe ngefasitela elisobala, okuvumela abathengi ukuthi babone ngqo uswidi ngaphakathi kwephakeji, okwandisa isilingo sokuthenga.
