Iteyiphu yesalathiso soxinzelelo lomphunga yenziwe ngephepha elithungwe njengesiseko sezinto, ezenziwe ngeedayi ezikhethekileyo zekhemikhali ezingeva bubushushu, abaphuhlisi bemibala kunye nezixhobo zabo ezincedisayo kwi-inki, zigqunywe nge-inki etshintsha umbala njengesalathiso sokuvala inzalo, kwaye igqunywe ngoxinzelelo. I-adhesive-sensitive adhesive ngasemva Iprintwa kwi-tape ekhethekileyo yokubambelela kwimizila ye-diagonal;phantsi kwesenzo se-steam egcweleyo kwiqondo lokushisa elithile kunye noxinzelelo, emva komjikelezo wokuvala inzala, isalathisi siba grey-black okanye mnyama, ngaloo ndlela sisusa umsebenzi wesalathisi seBacteria.Isetyenziselwa ngokukodwa ukuncamathisela kwipakethe yezinto eziza kwenziwa inzala kwaye isetyenziselwa ukubonisa ukuba ipakethe yezinto iphantsi koxinzelelo lwenkqubo yokuvala inzala, ukuze kuthintelwe ukuxutywa kunye nepakethe yezinto ezingavalwanga.
