Zvakajairika zvinodhaka kurongedza isu zvakanyanya kana zvishoma tichasangana nazvo, semuyenzaniso, common cold medicine packaging surface is a layer of aluminium foil yekurongedza, vanhu vazhinji vanofunga kuti dhizaini iyi yealuminium foil ingori chikamu chakasiyana chealuminium foil film, saizvozvo, kunyangwe ichiita seyakaonda kwazvo chidimbu chealuminium, asi chimiro chayo chakasiyana-siyana chezvigadzirwa zvemubatanidzwa.

Chimiro chezvakajairwa mishonga yekurongedza zvinhu zvakakamurwa kuita: surface layer (kudhinda layer), barrier layer (aluminium foil), yemukati layer (kupisa chisimbiso layer) adhesive (VC) multi-layer structure. Nheyo imwe neimwe inogadzirwa nezvinhu zvakasiyana uye inoshandisa chinangwa chakasiyana. Iwo matatu akaturikidzana akabatanidzwa pamwe chete neadhesive. Uye kudhinda kwakakamurwawo kuita kudhinda kwemukati uye kudhinda kwekunze, kudhinda kwemukati kunowanzo kudhindwa padivi remukati rebarrier layer, Kudhinda kwekunze kunogona kudhindwa padivi remukati remupendero wepamusoro unogona zvakare kudhindwa padivi rekunze rebarrier layer..

Aya akaturikidzana ane mabasa akasiyana uye hunhu hwezvinhu, aluminium foil surface ine yakanakisa kudhinda uye kushongedza, kupikisa kupisa kwakasimba, kupfeka kuramba. Kana yakapetwa kaviri kana yakawanda-layer yakaoma, iyo yepamusoro pedenga inogonawo kutamba chipingamupinyi; Iyi dhizaini yezvinhu zvinowanzoshandiswa ndeye PET, BOPP, PT, bepa, GADZIRA, etc., kazhinji zvinoenderana neyakasiyana zvigadzirwa kusarudza yakakodzera zvinhu.

Yepakati barrier layer: chikuru ndechekuita chipingamupinyi basa, iyi layer yezvinhu kuti ikwanise kudzivirira kupinda mukati nekunze gasi kana mvura, kuchengetedzwa kwemishonga yemukati. Panguva imwe, zvinodikanwawo kuve nekudzivirira kwakanaka kwechiedza kudzivirira mamwe madhiragi ekudzivisa chiedza kubva pakusangana nezuva. Zvose zvipingamupinyi zvinofanira kunge zviri pedyo nekuputira sezvinobvira. Iyi layer yezvinhu zvinowanzo shandiswa ialuminium foil kana firimu realuminium, GADZIRA, EVOH, PVDC, etc.

Inner layer: iyo yemukati layer ichave yakanangana nemushonga, iyi layer haidiwe kuti idyidzane nekurongedza kuti ibudise ngura kana kupinda; Iyo yemukati yakatsetseka uye inogona kumira kupisa kana kutonhora. Zvinowanzoshandiswa zvinhu PE, PP, EVA uye zvichingodaro.

Adhesive: Adhesive layer inoshandiswa kuita kuti chisungo chiri pakati pezvikamu zviwedzere uye chisimbise. Kazhinji inoumbwa nezvinhu zvinonamira, kurapa mumiririri, solvent, zvimwe zvinowedzera (plasticizer, filler, defoaming agent).
