0.51oz / 15ml PP Double-Wall Rounded Square Balm Jar with Flush Cap & PP Sealing Disc

What this packaging is

A rounded-square silhouette sets this jar apart from the standard cylinders and ovals dominating balm shelves. The 0.51oz / 15ml PP Double-Wall Rounded Square Balm Jar features a flush cap and PP sealing disc for a clean, seamless profile that reads premium at a glance. Double-wall PP construction adds structural integrity and helps insulate temperature-sensitive formulas like eye creams, lip balms, and lip masks. Every component — body, inner jar, cap, and sealing disc — is produced from the same polypropylene resin, keeping the material story simple. For brands developing compact, tactile balm packaging with strong shelf presence, this jar delivers a distinctive form factor in a right-sized 15ml format.

Why brands choose this

• Ownable shelf geometry in a crowded balm category: The rounded-square footprint breaks from the circular jars that dominate lip balm and eye cream fixtures, giving brands a distinct silhouette that's immediately recognizable on-shelf and hard for competitors to replicate at a glance.
• Double-wall construction protects temperature-sensitive formulas: Eye creams and lip masks often contain actives or butters that degrade with heat fluctuation. The double-wall PP build creates a buffer layer that adds both structural rigidity and a degree of thermal insulation — a meaningful functional benefit beyond aesthetics.
• Mono-material PP simplifies end-of-life messaging: Jar body, inner cup, cap, and sealing disc are all polypropylene, so brands working toward cleaner material stories can communicate a single-resin package to retailers and consumers without the asterisks that come with mixed-material designs.
