Why brands choose this

• Built-in child resistance for regulated categories: The ribbed PP child-resistant cap addresses a non-negotiable compliance requirement for pharmaceutical and supplement brands, removing the need to source closures separately and simplifying your component stack.
• 37-400 neck finish broadens your closure options: A 37-400 thread finish is one of the most common standards in supplement packaging, meaning this bottle works with a wide range of existing closures — useful when you're ranging across multiple SKUs or want flexibility in cap style without retooling.
• PCR material availability supports sustainability goals: For brands with commitments around recycled content, this bottle is available with PCR-inclusive HDPE — giving your product development team a tangible material story to build on without switching formats.
