What this packaging is

A wide 38-400 neck finish defines this round packer bottle, making it broadly compatible with standard closures and easy to source as a complete package. The 5oz/150cc 38-400 PET Vitamin Packer Bottle is built for the supplement aisle — proportioned to hold vitamins, capsules, gummies, antacids, and lozenges while fitting naturally on pantry shelves, in medicine cabinets, and gym bags. Its stackable, shipping-optimized profile keeps fulfillment efficient for both e-commerce and retail. For brands building out a supplement line or refreshing existing SKUs, this workhorse format delivers reliable, category-right packaging at scale.

Why brands choose this

• Category-right form factor, shelf to shelf: The round packer silhouette is the established consumer reference for vitamins and supplements — familiar enough to build immediate purchase confidence, and proportioned at 5oz to suit typical bottle counts across capsules, gummies, and lozenges without oversizing.
• 38-400 neck finish unlocks closure flexibility: A 38-400 neck is one of the most widely standardized finishes in the supplement category, meaning brands can pair this bottle with induction-seal caps, child-resistant closures, or desiccant-lined lids from multiple vendors without retooling or custom specs.
• Stackable geometry built for modern fulfillment: The bottle's dimensions and straight-wall packer shape are optimized for efficient stacking, making it a practical pick for high-volume e-commerce operations and retail shelf sets where space and shipping cost both matter.
