1.0oz /30ml 43-400 Straight-Sided PS Jar

What this packaging is

A straight-sided profile and 43-400 neck finish define this 1.0oz / 30ml PS jar, giving it a clean, consistent surface that works well for labels and offset printing. The 43mm diameter opening is wide enough for easy finger-dip access, making it a natural fit for face masks, balms, and tinctures in small-format rigid packaging. Made in the USA, this polystyrene jar supports shorter lead times for domestic brands sourcing 1oz components. Available in white with offset print capability for direct on-body branding, it covers the essentials for cosmetic and wellness SKUs that need a compact, no-fuss jar.

Why brands choose this

• Wide-mouth 43-400 finish suits finger-dip formats: The 43mm opening hits the functional sweet spot for face masks and balms, giving consumers easy, full-access application without the frustration of a narrow neck — a small but meaningful detail that shapes how a product is experienced at home.
• USA manufacture keeps timelines tight: Produced domestically, this jar sidesteps the long ocean-freight lead times that can stall a launch. For brands building out 30ml rigid-packaging SKUs, that sourcing proximity is a real operational advantage when speed-to-market matters.
• Offset print-ready surface opens direct branding options: The straight-sided geometry creates consistent, flat-plane registration that makes offset printing reliable and predictable. Brands can put copy or graphics directly on the jar body without relying solely on labels, which can peel or shift in humid bathroom environments.
