Idealpak 3.4oz/100ml 56-400 PET Straight-Sided Jar

What this packaging is

Wide-mouth and straight-sided, this 3.4oz/100ml PET jar is built for effortless filling, clean labeling, and fingertip-friendly dispensing — exactly what skincare and haircare brands need from a workhorse jar. The 56-400 neck finish supports a broad range of closure options, and the cylindrical silhouette gives decorators a flat, consistent surface for silk screen printing, heat stamping, spray coating, or embossing. At 2.36 inches in diameter and just 15g, it packs a generous 100ml capacity into a compact, shelf-efficient footprint. Available with PCR content for brands with sustainability commitments. A reliable, decoration-ready format for moisturizers, masks, scrubs, and hair treatments.

Why brands choose this

• Wide-mouth format built for thick formulas: The 56-400 opening makes filling and consumer dispensing genuinely easy for dense textures like scrubs, masks, and hair treatments — reducing production friction and matching the tactile ritual consumers expect from these categories.
• Flat cylindrical walls that decorators love: The straight-sided profile delivers a consistent, uninterrupted decorating surface compatible with silk screen printing, heat stamping, spray coating, and embossing — giving brand teams real flexibility to build shelf presence without switching suppliers.
• PCR content available for sustainability-minded brands: As clean beauty and responsible sourcing continue to drive purchasing decisions, the option to incorporate PCR material lets brands align this jar with their environmental commitments without changing the format or sourcing process.
