The 50ml round-shoulder & round-bottom serum bottle stands out as a sophisticated and versatile packaging solution tailored for premium skincare and cosmetic products. Its distinctive design features smoothly curved shoulders and a rounded base, creating a seamless and elegant silhouette that not only enhances ergonomic comfort during handling but also exudes a sense of luxury. This curved profile eliminates sharp edges, making it easy to grip and store, while also providing ample space for diverse customization options such as silk-screen printing, hot stamping, frosting, or gradient coating. Such flexibility allows brands to showcase their unique identities and product highlights, making the bottle a perfect fit for mid-to-high-end beauty lines seeking to differentiate themselves in a competitive market.

Complementing its elegant design is a high-performance 20-thread full-plastic double-layer dropper, engineered to deliver precise dispensing and reliable product protection. A key highlight of this dropper is its TPE rubber bulb, an eco-friendly material that is free from harmful substances such as phthalates, BPA, formaldehyde, and heavy metals. This ensures the bottle’s safety for use with skincare and cosmetic products, and it also meets international safety standards including FDA and RoHS, making it suitable for food contact and even medical applications. Additionally, the production process of the TPE rubber bulb requires no vulcanization, resulting in low energy consumption, and its waste is recyclable, aligning with global environmental protection trends and catering to the growing consumer demand for sustainable packaging.

The dropper’s other components further enhance its functionality and durability. The outer cap, made of AS/MS material, offers excellent rigidity and impact resistance, and it can be customized in transparent or colored options to match brand aesthetics. The PP threaded cap ensures a tight and secure fit with the bottle’s 20-thread neck, effectively preventing leakage and preserving product freshness. The glass dropper tube guarantees chemical stability, making it compatible with a wide range of formulations, including those with active ingredients.

With a 50ml capacity that is ideal for full-size daily-use products, this bottle is suitable for packaging various skincare and cosmetic items such as serums, emulsions, and liquid foundations. Its compatibility with standard 20mm screw-neck finishes also provides flexibility for alternative closure options if needed. Crafted to meet global cosmetic packaging regulations, the 50ml round-shoulder & round-bottom serum bottle combines aesthetic appeal, functional performance, and environmental sustainability, making it an excellent choice for brands looking to elevate their product packaging and meet consumer expectations for quality and eco-friendliness.
