Idealpak 0.3oz/9ml 20-400 HDPE Mini Packer Bottle for Sampling & Trial

What this packaging is

At just 0.3oz/9ml, this HDPE Mini Packer Bottle is built for the moments before a customer commits — sampling programs, clinic giveaways, subscription box inserts, and travel kits. The 20-400 neck finish gives you genuine closure flexibility, from child-resistant caps to flip-tops, making it a practical fit for vitamins, supplements, pills, and capsules. HDPE construction delivers solid moisture and impact resistance, which matters when bottles are moving through e-commerce fulfillment or third-party logistics. Compact dimensions — 1.81 inches tall, 0.98-inch diameter — keep things tight in any secondary packaging. For brands using trial formats to drive conversion, this little bottle does the heavy lifting.

Why brands choose this

• 20-400 neck keeps closure options wide open: Child-resistant, flip-top, disc-top — the 20-400 finish is one of the most widely stocked neck finishes in the industry, so sourcing closures stays simple and cost-efficient as your program scales.
• Format matches the supplement sampling ritual exactly: Single-dose or short-supply trial packs are a proven conversion tool in the vitamins and supplements category — this bottle's capacity and form factor align directly with how brands in that space are acquiring and retaining customers.
• HDPE durability built for e-commerce and clinic distribution: Impact resistance and low moisture permeability mean product integrity holds up across shipping, handling, and storage — critical when trial units are moving through fulfillment centers or being handed out in clinical settings.
