12oz / 355ml 38-400 PET Square Juice Bottle

What this packaging is

A square silhouette sets this bottle apart on shelf where round formats dominate. The 12oz / 355ml 38-400 PET Square Juice Bottle is built for beverage brands that want a clean, structured look without sacrificing practicality. The wide 38-400 neck finish makes filling and capping straightforward, and the flat-sided geometry gives labels excellent surface area to work with. At 2.13" wide and 6.25" tall, it's compact enough for single-serve formats. Made in the USA, it's a strong fit for juice, non-dairy milk, mixers, and similar refrigerated or shelf-stable drinks. Stock availability supports smaller orders for test launches.

Why brands choose this

• Square format earns shelf presence round bottles can't: Flat-sided geometry is genuinely rare in the single-serve beverage aisle, giving brands an ownable structural silhouette. As consumers scan crowded cooler shelves, a square profile creates an immediate visual break from standard round bottles.
• Wide 38-400 neck finish supports fast, flexible filling: The 38-400 neck opening accommodates a range of capping equipment and filling speeds, reducing line changeover friction. It's equally practical for thicker pours like oat milk and thinner juice blends, making it a versatile format across multiple SKUs.
• USA manufacturing keeps lead times tight for domestic brands: Produced in the USA, this bottle sidesteps the long ocean freight windows and customs complexity that come with overseas sourcing. For emerging beverage brands or regional co-packers, that speed to shelf is a real operational advantage.
