Study on Interfacial Bonding Strength of SiO₂/PET Composite Packaging Film

Abstract:

SiO₂/PET composite packaging film was prepared by depositing SiO₂ on PET film substrates through magnetron sputtering technology. The state of SiO₂ particles and its dispersion properties in PET substrates were characterized by scanning electron microscope (SEM) and bonding strength tester. The effects of the sputtering process parameters and intermediate layer on the bonding strength of the coating-substrate system were investigated. Results show that the bonding strength of coating-substrate system firstly increases and then decreases with the increase of sputtering process parameters. It is up to a maximum at the argon flow of 10 mL/min, radio-frequency power of 250 W and sputtering time of 70 min; and it is 0.14 MPa, 0.22 MPa and 0.19 MPa, respectively. The bonding strength of coating-substrate system increases with the increasing background pressure. Meanwhile, we find that the bonding strength of coating-substrate system is improved by depositing A1₂O₃ intermediate layer between SiO₂ film and PET substrates.
