31.5oz /932ml 28-400 Boston Round PET Bottle

What this packaging is

A workhorse 28-400 neck finish and 932ml capacity make this PET round bottle one of the most cross-category flexible formats available at this size. The 31.5oz PET Round Bottle handles everything from cold brew coffee and plant-based milks to body wash, shampoo, dish soap, and laundry detergent — all in one clean, glossy silhouette that labels and hot stamps well. Compatible with a wide range of standard 28-400 closures, it removes sourcing complexity when scaling across multiple SKUs. Available with PCR content for brands with sustainability commitments. At nearly a liter of capacity, it's a natural fit for brands ranging product lines across both food and personal care.

Why brands choose this

• Multi-category range in a single bottle format: Spanning food and beverage (cold brew, juice, plant-based milks) through personal care (shampoo, body wash) and household (dish soap, laundry detergent), this bottle lets brand teams consolidate vendors and streamline development across very different product lines — a real advantage when ranging SKUs at speed.
• Standard 28-400 neck unlocks closure flexibility: The 28-400 neck finish is one of the most widely available closure standards on the market, meaning you're not locked into proprietary caps. Pump dispensers, flip-tops, disc caps, and screw closures all play well here, reducing lead time and vendor dependency as your line evolves.
• PCR-compatible for brands with sustainability targets: Available with PCR content for brands working toward recycled material commitments, this bottle supports a reduce story without requiring a format change. Paired with its recyclable PET construction, it gives product developers a credible, material-level sustainability narrative at a high-volume, everyday price point.
