35mm 1.4-4.1oz (40ml-120ml) PE Airless Serum Pump Tube with PP Overcap

What this packaging is

Vacuum-pump mechanics inside a flexible PE tube body — that's the defining story of the 35mm 1.4–4.1oz PE Airless Serum Pump Tube with PP Overcap. The bottom-up evacuation system achieves over 95% product evacuation, making it a smart pick for oxidation-sensitive formulas like retinoids, peptide serums, and SPF. Available in 40ml to 120ml capacities with monolayer or co-extruded PE constructions, it comes in glossy, matte, or soft-touch finishes to fit a range of brand aesthetics. TSA-friendly sizing makes it easy to position across travel retail. From face serums to body oils and foundations, this airless tube keeps formulas potent from first use to last.

Why brands choose this

• Bottom-up airless evacuation protects high-performance actives: Retinoids, peptide complexes, and vitamin C serums degrade fast when exposed to air. The bottom-up piston mechanism in this tube isolates product from oxygen throughout its entire use life — not just at first pump — keeping efficacy intact and reducing consumer waste.
• Over 95% product evacuation turns premium formulas into premium value: As brands invest more in high-cost actives, dead-space waste is a real cost. Achieving 95%+ evacuation means consumers actually get what they paid for, which supports brand trust, repeat purchase, and fewer complaints about "empty" tubes with product still inside.
• Multi-category versatility from a single tube platform: One component spanning face serums, body oils, foundations, concealers, eye creams, spot treatments, and SPF gives brand teams real ranging efficiency. Testing and qualifying one format across multiple SKUs simplifies development timelines and consolidates sourcing without sacrificing category-specific positioning.
