Isikhwama esinezinhlangothi ezintathu sokuvala uziphu singathathwa njengokuhluka kwesikhwama se-aluminium foil esinezinhlangothi ezintathu esivala uphawu. Ngesisekelo sokubekwa uphawu ezinhlangothini ezintathu, i-zipper yokuzivala ifakwe emlonyeni wesikhwama. . I-zipper enjalo ingavulwa futhi ivalwe izikhathi eziningi futhi ingasetshenziswa izikhathi eziningi. Lolu hlobo lokupakisha lufaneleka kakhulu esimweni sokuthi usayizi wesikhwama mkhulu kancane, futhi imikhiqizo esesikhwameni ayikwazi ukusetshenziswa ngesikhathi esisodwa.
Isibonelo, izithelo ezomisiwe, amantongomane, izinongo ezomile, ukudla okuyimpuphu, nokudla okungenakudliwa ngesikhathi esisodwa kusetshenziswa kakhulu ezikhwameni zokupakisha zepulasitiki ezinoziphu noma izikhwama zepulasitiki ezizinamathelayo ezineglue. Izikhwama zokufaka ukudla ezifakwe uziphu kanye nezikhwama zokupakisha ezizinamathelayo ziyizikhwama zepulasitiki zokupakisha. Ngemva kokuvulwa kwesikhwama, singavalwa kabili. Nakuba ingakwazi ukufeza umphumela wokubekwa uphawu kokuqala, ingasetshenziswa njengobufakazi bomswakama nsuku zonke kanye nothuli ngesikhathi esifushane. Kusengenzeka.
Isikhwama se-zipper sokuvala uphawu esinezinhlangothi ezintathu singasetshenziswa ngabathengi ngezinga elikhulu, futhi sibiza kancane kunesikhwama se-aluminium se-aluminiyamu sokuvala izinhlangothi ezintathu, kodwa sithandwa kakhulu phakathi komphakathi ngenxa yokusebenza kwayo okulula nokulula. Kukhona futhi izinketho eziningi uma kuziwa ekwenzeni ngokwezifiso isikhwama.
Ukuvalwa koziphu okuvalekayo
Ibonisa ngale ukuze ibonise imikhiqizo esikhwameni
Yonke imikhiqizo ihlolwa ngokuyisibopho ngelebhu ye-QA esezingeni eliphezulu Futhi ithole isitifiketi selungelo lobunikazi.
