Idealpak 1.4oz/40ml 18-410 PET Boston Round Cosmetic Bottle

What this packaging is

The classic boston round silhouette gives this 1.4oz/40ml PET bottle an instantly recognizable profile that fits naturally into serum, facial oil, and CBD oil rituals. At just 1.28" wide and 2.95" tall, the compact footprint keeps things shelf-friendly and travel-ready. The 18-410 neck finish opens up a wide range of closure options — pumps, droppers, disc tops — without locking brands into a single dispensing format. Decoration via silk screen or embossing translates cleanly onto the curved surface. Part of a boston round family spanning 30ml to 1000ml, it supports cohesive product line ranging for brands scaling across categories.

Why brands choose this

• Range-ready silhouette across a full size family: The 18-410 boston round format runs from 30ml to 1000ml, letting brand teams develop a cohesive visual line across multiple SKUs without switching suppliers or silhouettes — a real advantage when ranging serums, face oils, or CBD products together.
• Flexible dispensing through a widely compatible neck finish: The 18-410 neck finish works with pumps, droppers, and disc-top closures, so brands can test different dispensing formats on the same bottle before committing — useful for category expansions or consumer testing phases.
• Sustainable sourcing available for material-conscious brands: PCR content can be incorporated into the PET for brands with material reduction or sustainability commitments, giving this accessible format a credible story beyond its standard spec.
