①Pepa-plastiki inoumbwa zvinhu. Pepa rine maitiro akanaka ekudhinda, kunaka kwemhepo kupinza, kusamira zvakanaka kwemvura, uye deformation mukubata nemvura; firimu repurasitiki rine kumira zvakanaka kwemvura uye kusimba kwemhepo, asi kusadhinda kwakashata. Mushure mokunge maviri acho asanganiswa, zvinhu zvakasanganiswa zvakadai sepurasitiki-pepa (plastiki firimu sechinhu chepamusoro), pepa-plastiki (pepa sechinhu chepamusoro), uye plastiki-pepa-plastiki inoumbwa. Iyo pepa-plastiki inosanganiswa zvinhu inogona kuvandudza kunyorova kwepepa, uye panguva imwechete ine kumwe kupisa kuvharika. Inogona kusanganiswa nekuoma kusanganisa maitiro, kunyorova kusanganisa maitiro uye extrusion kusanganisa maitiro.

②Plastiki inoumbwa zvinhu. Plastic-plastic composite zvinhu ndiyo inowanzozivikanwa yemhando yezvinhu zvinosanganiswa. Mafirimu epurasitiki akasiyana-siyana ane zvakanakira uye zvisingabatsiri. Mushure mekuvasanganisa, icho chitsva chine zvinhu zvakanakisa senge mafuta kuramba, hunyoro kuramba, uye kupisa kuvharika. Mushure mekugadzirwa kwepurasitiki-purasitiki, maviri-layer, matatu-layer, mana-layer uye zvimwe zvinhu zvinosanganiswa zvinogona kuumbwa, senge: OPP-PE BOPET - PP, PE, PT PE-evoh-PE.

③Aluminium-plastiki inoumbwa zvinhu. Kusimba kwemhepo uye zvipingamupinyi zvealuminium foil zviri nani pane zvefirimu repurasitiki, saka dzimwe nguva purasitiki-aluminium-plastiki inoumbwa, yakadai sePET-Al-PE, inoshandiswa.

④Pepa-aluminium-plastiki inoumbwa zvinhu. Iyo bepa-aluminum-yepurasitiki inoumbwa zvinhu inoshandisa yakanaka kudhindwa kwebepa, yakanaka-inoratidza hunyoro uye kudziya kwealuminium conductivity, uye yakanaka kupisa-kuvharika kwemamwe mafirimu. Kuzvibatanidza pamwe chete kunogona kuwana chinhu chitsva chakaumbwa. Zvakadai sepepa-aluminium-polyethylene.

Fexo muchinazvisinei kuti imhando ipi yezvinhu zvakaumbwa, zvinodikanwa kuti iyo yekunze ine printability yakanaka uye mechanical properties, iyo yemukati layer ine yakanaka kupisa-sealing adhesion, uye yepakati layer ine zvinhu zvinodiwa nezviri mukati, senge kuvharika kwechiedza. , mwando chipingamupinyi uye zvichingodaro.
