Chinese soup-based foods are prone to packaging damage during delivery due to bumps or squeezing, resulting in soup leakage.
Improving the puncture resistance of aluminum foil tissue paper requires comprehensive design from multiple dimensions, including materials, structure, process, thickness, surface treatment, and environmental adaptability.
The cleanliness, temperature, and humidity of the production workshop can affect the surface condition of aluminum foil and the stability of the stamping process.
The coefficient of friction test is a core indicator, and the dynamic friction performance of aluminum foil and aluminum foil tissue paper needs to be evaluated by simulating actual use scenarios.
Aluminum foil surfaces are typically anodized or coated to form a dense oxide film or functional coating.
Passivation treatment is a process that uses chemical reagents to form a thin and dense passivation film on the surface of aluminum foil, thereby improving its corrosion resistance.
