Mapaketi osinthasintha a chakudya cham'zitini ayenera kutchedwa mapakiketi osinthasintha okhala ndi zipilala zambiri, kutanthauza kuti, okhala ndi zojambulazo za aluminiyamu, aluminiyamu kapena ma flakes a alloy, ethylene vinyl alcohol copolymer (EVOH), polyvinylidene chloride (PVDC), oxide-coated (SiO3 kapena Al2O3) acrylic resin layer kapena Nano-inorganic substances ndi gawo lotchinga, ndipo kuchuluka kwa mpweya wolowa m'malo mwa unit mkati mwa maola 24 ndi kochepera 1mL pansi pa kutentha kwa 20℃, kuthamanga kwa mpweya kwa 0.1MPa ndi chinyezi cha 85%. phukusi la. Chakudya cham'zitini chosinthika chiyenera kutchedwa chakudya chosinthika chokhala ndi zipilala zambiri, chomwe nthawi zambiri chimatchedwa chakudya chofewa cham'zitini, chomwe chimagwiritsa ntchito ziwiya za aluminiyamu-pulasitiki kapena pulasitiki zosakanikirana kwambiri mutakonza zinthu zopangira monga ziweto, nkhuku, zinthu zam'madzi, zipatso, ndiwo zamasamba, ndi tirigu zomwe zikukwaniritsa zofunikira. Chakudya chomwe chatsekedwa (chodzazidwa), chotsekedwa, chosawilitsidwa kapena chodzazidwa ndi aseptic kuti chikwaniritse zofunikira za malonda. Pakadali pano, pali chakudya chofewa cha m'zitini chochulukirachulukira m'dziko lathu, makamaka chakudya chosangalatsa cha m'zitini kuti chikwaniritse zosowa za ogula paulendo wawo komanso moyo wawo wachangu. Nthawi yomweyo, ukadaulo wosinthasintha wa kukonza ma CD mdziko langa wakula pang'onopang'ono, ndipo chitukuko cha zipangizo zosinthika zosungira ndi zotengera chawonjezeka makamaka chifukwa cha kuyambitsa ukadaulo wakunja. Komabe, dziko lathu silinagwire ntchito yochuluka pakuwunikira zoopsa ndi kupanga zinthu zosinthika zosungira. Pakadali pano, miyezo yoyenera yowunikira komanso miyezo yotetezeka ya chakudya ikukhazikitsidwa.
