Ukudla okubandayo kulula ukulondolozwa nokusetshenziswa kabanzi emkhiqizweni, ezokuhamba, nokugcinwa kokudla okungonakali njengenyama, izinkukhu, ukudla kwasolwandle, ubisi, amaqanda, imifino nezithelo; Izakhamzimba, lula, inhlanzeko kanye nomnotho; Isidingo semakethe siphezulu . Ukuze sikwazi ukulungiselela isitoreji, silondoloze inhlanzeko kanye nokuhlanzeka, kudingeka ukuthuthukiswa kwezinto ezifakwe iqhwa, okushayela ukuthuthukiswa komkhakha wokupakisha we-vacuum {
1. Ukudla okubandayo empumalanga kusebenzisa izinto ezivuthayo ze-PP izithako zazo, eziphephile, ezingezinhle, nezindinganiso zokuqina kokudla, kanye nokuphikiswa kokugqwala kwamakhemikhali, nokumelana nokugqwala okuphezulu kwemikhiqizo ye-PP vacuum eyenziwe . Izinto zokusetshenziswa ze-PP zilungele ukufakwa kokudla okuqandisiwe, njengamabhokisi e-ayisikhilimu, amabhokisi okulahla, amabhokisi okulahla amanzi, njll {.
2. ukuvikelwa okuhle, okucacile nokunembile, okulula ukuyisebenzisa, kanye nekhwalithi elula .
3. Ngemuva kokupakishwa kwe-vacuum, izinto zihlotshisiwe, ikhwalithi iyathuthuka, futhi amakhasimende anesifiso esikhulu sokuthenga .
4. Uma i-nitrogen ingezwe ebhokisini lokufaka iqhwa ngemuva kokulifaka uphawu ngefilimu, lizoba nomthelela othile ekugcinweni kokudla, kanye nempilo ejwayelekile yeshalofu yi- . .}
5. uqhwa ebhokisini lepulasitiki elisungulwe, elihlanzekile nenhlanzeko, ukugcinwa kanye nokufaka, ukusindisa isikhala, ukuthuthwa okulula .
