30ml Serum Bottle（JH-181Z）

This 30ml slender straight round bottle is a classic and minimalist container ideal for serum, essential oil and other skincare formulations. Featuring an elongated slim silhouette, the bottle presents an elegant, refined visual effect, easy to grip and perfectly compatible with routine cosmetic packaging designs.
It is matched with a press dropper assembly with complete standardized accessories. The set includes a middle collar, ABS press button, PP inner liner, 20-tooth press dropper and NBR rubber cap. The 20# PE guide plug is equipped to achieve stable flow control during use. Each component is carefully selected for outstanding chemical resistance. The NBR cap delivers reliable sealing performance to effectively prevent liquid leakage, isolate air and extend the shelf life of essential oils and active ingredient serums. The ABS press button offers smooth, comfortable pressing feedback, bringing users a convenient and controllable dispensing experience. The PP inner liner strengthens the assembly tightness and avoids looseness during long-distance transportation.
With a 20-thread specification, the bottle mouth ensures precise matching with the supporting dropper set. The PE guide plug can limit outflow volume, preventing excessive waste of high-value raw materials such as essences and essential oils. The entire packaging set supports assembly in advance, greatly simplifying your filling and production workflow.
Suitable for private label customization, this container works well for facial serums, plant essential oils, repair essences and concentrated skincare liquids. Its simple cylindrical shape leaves sufficient space for silk-screen printing, labeling and hot stamping. The stable structure minimizes collision damage during transit. We support bulk wholesale and can cooperate on customized surface treatments to meet differentiated brand positioning, becoming a cost-effective packaging choice for mid-to-high end skincare brands.
