3.4oz/100ml 56-400 PET Single-Wall Straight Sided Jar with Cap

What this packaging is

A straight-sided silhouette with a 56-400 neck finish gives this 3.4oz/100ml PET jar a clean, stackable profile that works hard across skincare and hair care lines. The 3.4oz/100ml 56-400 PET Single-Wall Straight Sided Jar with Cap is compact at 2.06" tall and 2.36" in diameter, leaving a generous label area for branding. Part of an adjustable mold series, the design accommodates height variations to hit different capacity targets without retooling entirely. At just 15 grams, it keeps shipping costs in check. Built for face moisturizers, masks, scrubs, and hair treatments, it's a practical workhorse for brands ranging across multiple SKUs.

Why brands choose this

• Adjustable mold series spans multiple capacities: The height-adjustable mold design lets brand teams dial in different fill volumes without committing to a completely new tool, reducing development time and cost when ranging across product lines.
• Wide label surface supports strong shelf branding: The straight-sided profile maximizes usable label real estate, giving brands clean, flat space for full-wrap graphics, regulatory copy, and on-shelf storytelling — a real advantage in a competitive skincare aisle.
• Multi-category versatility across face and hair care: One jar format covering face moisturizers, masks, scrubs, and hair treatments means fewer vendors, simpler procurement, and easier visual cohesion across a product range — a genuine advantage for growing brand teams managing multiple SKUs.
