Idealpak 56-400 PP Straight Sided Flat Cap

What this packaging is

A clean flat-top profile and smooth straight sides make this 56mm cap a natural fit for wide-mouth personal care containers. The 56-400 PP Straight Sided Flat Cap is a polypropylene threaded closure with a 400-finish thread, sized at 2.32 inches in diameter and weighing just 6.2 grams — secure and functional without adding unnecessary bulk. The flat surface is label-ready, giving brand teams an easy path to on-pack decoration. Manufactured in China, it's a well-priced, reliable choice for face moisturizers, body butters, hair treatments, and pomades where a no-fuss, professional finish is the goal.

Why brands choose this

• Label-ready surface streamlines on-pack branding: The flat-top profile provides a clean, uninterrupted surface that accepts labels without contouring challenges — letting brand teams execute consistent, professional decoration across a full product range without additional tooling or process steps.
• 400-finish thread ensures broad container compatibility: The industry-standard 56-400 neck finish means this cap is compatible with a wide range of stock containers, reducing sourcing friction and making it easy to swap or scale across SKUs without retooling or requalifying components.
• Lightweight PP construction matches category expectations: At just 6.2 grams, this cap keeps material use lean while still delivering a secure, confident closure — well suited to the tactile norms of everyday-use formats like moisturizers, body butters, and pomades where lightweight functionality drives repeat consumer interaction.
