17.5-410 Monomaterial PP Auto-loading Push Button Dropper

What this packaging is

Metal-spring-free and built entirely from PP, the 17.5-410 Monomaterial PP Auto-loading Push Button Dropper replaces traditional spring components with a PP/TPE spring — making it a genuinely mono-material dropper that simplifies end-of-life sorting. Manufactured in South Korea by FS Korea, this push-button dropper delivers precise, controlled dispensing through an auto-loading mechanism that resets cleanly after each press. The 17.5-410 neck finish, 3.94" height, and 1.21" diameter keep the profile sleek and shelf-ready. Available with PCR content for brands with material reduction commitments. Ideal for face serums and hair oils where dosage control and elevated presentation both matter.

Why brands choose this

• True monomaterial construction supports recyclability goals: Unlike most droppers that combine PP with metal springs, this component swaps metal for a PP/TPE spring — keeping the material stream cleaner and making it easier for brands to substantiate responsible packaging claims. Available with PCR content for brands tracking material reduction targets.
• Push-button auto-loading mechanism matches high-demand serum rituals: The format mirrors what consumers already expect from premium face serum and hair oil packaging — controlled, drip-free dispensing with no pump fatigue. As skincare consumers increasingly scrutinize application precision, a dropper that resets reliably after every press removes a common friction point at the moment of use.
• South Korea manufacturing brings design precision and quality consistency: FS Korea's ADR Series reflects the tight tolerancing and finish quality that Korean component manufacturing is known for — especially relevant for brands sourcing prestige skincare and hair care packaging where surface detail and mechanism reliability directly affect perceived product value.
