Surface adhesion of inkjet printing on HDPE/LDPE and LDPE/PET multilayer packaging

Key Points

• The inkjet printing achieved enhanced adhesion on HDPE/LDPE compared to LDPE/PET multilayers, indicating significant material differences.
• Adhesion strength was quantitatively assessed, revealing superior performance metrics during tests of surface bonding in multilayer configurations.
• Analysis of surface properties revealed critical interactions between inkjet inks and polymer layers, which inform best practices for printing.
• These findings may enable advancements in packaging technologies, especially for products requiring durable print quality and adherence.
