Two histories, two consumer expectations
Collapsible aluminum tubes still signal pharmacy heritage and certain color categories. Plastic squeeze tubes dominate mass personal care for resilience and decoration speed. Choosing between them is partly chemistry, partly brand semiotics.
Internal coatings and pH
Aluminum requires internal lacquers matched to pH and polarity. Getting that wrong shows up as corrosion pits or off-taste in oral-adjacent products. Plastic avoids metal corrosion but may need barrier upgrades for the same actives.
Logistics and decoration
Aluminum dents; plastic rebounds. Decoration cycles differ: metal often favors certain ink systems and emboss paths, while plastic opens wide CMYK plus soft-touch coatings. Factor scrap rates and line speeds into unit economics, not only piece price.
Takeaway
Pick aluminum when collapse behavior, perceived purity, or heritage cues matter. Pick plastic when toughness, complex art, or lightweighting dominates. Hybrid launches should be rare—support both supply chains only when the margin truly allows.
