Chisimbiso chinoputika chinogadzirwa nefirimu inofema uye Heat induction seal (HIS) kuburikidza ne ultrasonic kana inopisa melt welding, iyo inonyatsozadzisa mhedzisiro ye "kufema uye isina kubuda".Chisimbiso chakavharwa chine dhizaini yakapusa, yakanakisa kupenya kwemhepo uye yakanakisa kuramba kune surfactants.Ichi chigadzirwa chinogadzirwa kudzivirira mudziyo wekuzadza (bhodhoro) kubva pakuzununguswa kana kuiswa pane tembiricha dzakasiyana kuti uburitse gasi mushure mekuzadza imwe mvura, nekudaro zvichiita kuti mudziyo uparare kana kuti chivharo chebhodhoro.
Vented liner ndiyo yakanakisa kufefetera kwemhepo muindasitiri, akawanda venting sarudzo inozadzisa akasiyana mashandiro ekuita.Inopihwa muchidimbu furo kana zvidimbu zviviri wakisi yakasungirirwa pahura.
