5.3oz / 156ml PET Plastic Erlenmeyer Flask Bottle with Baffled Bottom, Graduated Markings & Ribbed Screw Cap

What this packaging is

An Erlenmeyer flask silhouette in a consumer packaging context is a genuine standout — and this 5.3oz / 156ml PET bottle leans into that fully. The baffled bottom creates structural interest while improving stability, and the graduated markings make fill-level monitoring practical for both production teams and end consumers. A ribbed screw cap with a 32-410 neck finish keeps the format functional across face toners, hair treatments, and surface cleaners. Lightweight at 28.5g, it's built for efficient shipping and storage. Available with PCR content for brands building toward more responsible sourcing. A smart pick for brands that want a distinctive silhouette without sacrificing utility.

Why brands choose this

• Ownable flask shape that stands out on shelf: The Erlenmeyer silhouette is rare in consumer beauty and personal care, giving brands an immediately distinctive presence in toner, scalp treatment, and cleanser categories where standard cylinder and oval bottles dominate.
• Graduated markings add functional credibility: Visible fill-level markings align with the clinical, efficacy-forward positioning trending across skincare and hair care — giving consumers a precision cue that reinforces ingredient transparency and measured application.
• PCR content available for responsible sourcing goals: Brands working toward sustainability commitments can spec PCR material into this bottle, supporting reduce-and-reuse narratives without changing the format or consumer experience.
