30ml Serum Bottle（JH-24Y）

This 30ml cosmetic bottle features a sleek and slender rectangular bottle shape with a moderate capacity, achieving a perfect balance of aesthetic presentation and practical application. The streamlined slender structure delivers a neat, high-end visual effect, which is different from conventional round bottles, bringing a unique and premium product texture. With moderate volume design, it is neither too bulky for daily storage nor too small for frequent use, making it highly versatile for diversified cosmetic packaging scenarios. This bottle is specially suitable for packaging skincare essences, hair care essential oils and other high-value liquid products, meeting the daily use and commercial sales needs of beauty and hair care brands.
The product is equipped with a premium anodized aluminum dropper set with standardized and reliable accessory configurations to ensure safe storage and convenient use of internal liquids. The complete matching accessories include PP inner lining, alumina shell, 20-tooth trapezoidal NBR rubber cap and 20# PE guide stopper. Adopting high-quality cosmetic-grade materials, all accessories possess excellent chemical stability, corrosion resistance and sealing performance. The sturdy alumina shell enhances the texture and durability of the dropper, while the PP inner lining effectively isolates liquid contact with metal materials, avoiding ingredient deterioration and ensuring product safety and purity.
The 20-tooth trapezoidal NBR rubber cap provides excellent elasticity and airtightness, cooperating with the PE guide stopper to realize precise liquid output and effective leak-proof and anti-volatilization effects. This structural design effectively prevents external air and dust from entering the bottle, locks the activity of essence and essential oil ingredients, and prolongs the product shelf life. In terms of mass production customization, this product has a unified and standardized minimum order quantity. The MOQ for conventional electroplated rubber caps and customized special-color rubber caps is both 50,000 pieces. With unique appearance, stable quality and wide applicability, this 30ml slender rectangular bottle is an ideal packaging solution for skincare and hair care liquid products.
