Keyuan Packaging 3.4oz/100ml 24-400 PET Round Bottle with Smooth Straight Sided PP Screw Cap

What this packaging is

A straight-sided, round PET bottle with a 24-400 neck finish, this 3.4oz/100ml format is built for the kind of multi-closure versatility that product developers actually need. The 24mm neck accommodates screw caps, lotion pumps, disc tops, and flip caps, so one bottle works across formulation stages and retail configurations. At 108mm tall and 44mm in diameter, the proportions are compact enough for travel retail and TSA-compliant sets without feeling insubstantial on shelf. The included smooth straight-sided PP screw cap keeps things clean and minimal. Purpose-built for face toners, light serums, and rinse-off formats, it's a reliable workhorse for brands building out a skincare range.

Why brands choose this

• Multi-closure compatibility accelerates development timelines: The 24-400 neck finish works with screw caps, lotion pumps, disc tops, and flip caps — meaning brand teams can test different dispensing formats on a single bottle without re-tooling or switching components mid-development.
• Compact proportions nail the travel retail opportunity: At 100ml and 108mm tall, this bottle hits the TSA carry-on limit exactly, making it a natural fit for travel-size SKUs, trial packs, and travel retail channel entries — a fast-growing segment for toners and prep-step skincare.
• Decoration-ready surface supports brand buildout: Compatible with silk screen printing, hot stamping, and label application, the straight-sided round profile gives brand teams clean, flat real estate for decoration — practical for both startup launches and larger retailers requesting branded secondary packaging.
