17oz /500ml 28-400 Cosmo Round PET Bottle

What this packaging is

A 28-400 neck finish on a 500ml PET round bottle opens up a wide world of compatible pumps, disc caps, and flip-tops — making the 16.9oz / 500ml 28-400 PET Round Bottle one of the more closure-flexible options in this size range. Built from durable, lightweight PET, it handles everything from body lotion and shampoo to dish soap, surface cleaners, and automotive washes without skipping a beat. Hot stamping and label decoration keep branding options open. For brands with sustainability targets, PCR content is available to reduce virgin plastic use. A workhorse format that earns its place across personal care and household product lines alike.

Why brands choose this

• One neck finish, endless closure compatibility: The 28-400 finish is one of the most widely stocked neck sizes in the industry, meaning pumps, flip-tops, disc caps, and lotion pumps are all on the table — reducing sourcing friction when you're developing or scaling a product line.
• Spans personal care and household without missing a beat: From shampoo and body wash to dish soap and automotive washes, this bottle's format handles high-viscosity and low-viscosity fills equally well — a real advantage for brand teams developing ranges across more than one category.
• PCR content available for brands with material reduction goals: Virgin PET is the default, but PCR content can be incorporated for brands looking to reduce their reliance on fossil-based plastic — a credible, tangible sustainability story that resonates with increasingly materials-conscious retail buyers and consumers.
