1oz/30ml 37-400 HDPE Straight Sided Supplements Container

What this packaging is

Compact at just 1.48" tall and 1.61" in diameter, this 1oz/30ml HDPE straight-sided supplements container is built for single-serve and travel-size supplement formats. The 37-400 neck finish opens up a wide range of closure compatibility, making it easy to spec the right cap for vitamins, capsules, lozenges, powders, or pills without starting from scratch. Single-wall HDPE construction keeps weight and cost down while delivering solid protection for dry formats. Custom color options are available with an 8–10 week production lead time — a practical lever for brands looking to differentiate across SKUs or build a recognizable product line.

Why brands choose this

• 37-400 neck finish unlocks broad closure options: The standard 37-400 finish is compatible with a wide variety of cap styles — from child-resistant to flip-top — so your sourcing team isn't locked into a single vendor or closure type, which keeps both development timelines and costs flexible.
• Compact format matches the single-serve supplement trend: At 1oz/30ml, this container hits the sweet spot for travel-size and daily-dose supplement packaging — a format consumers actively seek out for vitamins and capsules, and one that performs well in DTC and trial-size retail channels.
• Custom color availability supports multi-SKU brand architecture: With color customization available on production runs, brands can use shade differentiation to signal product variants — think flavor, dosage, or formula — which is a practical and cost-effective tool for building a cohesive supplement line on shelf.
