Superior Barrier Protection
The hallmark feature of blister alu alu packaging lies in its exceptional barrier properties, achieved through its unique dual-aluminum construction. The cold-formed aluminum base layer, typically ranging from 45 to 50 microns in thickness, creates an impenetrable barrier against external elements. When combined with the aluminum lid foil, which usually measures 20 to 25 microns, the package provides complete protection against moisture, oxygen, and light. This level of protection is particularly crucial for moisture-sensitive pharmaceuticals, where even minimal exposure to humidity can compromise product efficacy. The aluminum structure maintains a constant internal environment, preventing oxidation and degradation of sensitive compounds, thereby ensuring product stability throughout its intended shelf life.
