200ML round-shoulder bottle（SF-218S1）

This premium 200ml cosmetic bottle is specially engineered for lightweight water-based skincare formulations, serving as an ideal packaging container for facial toners, pure floral hydrosols, and other gentle hydrating liquids. Distinguished by its smooth, round shoulder contours, the bottle boasts a soft and streamlined silhouette that replaces harsh angular designs, delivering a minimalist, sophisticated and modern aesthetic. The seamless transition from the rounded shoulder to the straight cylindrical body creates a balanced and elegant shape, which greatly enhances product visual appeal and brand grade. With a standard 200ml capacity, it perfectly accommodates daily household skincare routines while remaining lightweight and portable for travel, business trips and outdoor activities, meeting diverse consumer usage scenarios.

This bottle is fitted with a functional full-plastic flat top cap, adopting a scientific multi-component composite structure with categorized high-quality materials to ensure safety, durability and stable sealing. The flat top outer cap is crafted from high-rigidity ABS material, featuring outstanding hardness, abrasion resistance and structural stability. It resists deformation and cracking during daily use and long-distance transportation, and supports diversified surface finishing including glossy polishing, matte frosting, electroplating and custom color spraying, offering flexible personalized design options for cosmetic brands.

The cap is internally equipped with a food-grade PP lining that excels in chemical corrosion resistance. It remains stable when in long-term contact with toner and pure露 ingredients such as plant essences and dilute alcohol, preventing chemical reactions and impurity precipitation to protect the internal skincare liquid purity. Cooperating with the lining is a high-flexibility PE inner plug and a thickened PE gasket. The combination forms a tight dual sealing structure that closely fits the bottle mouth, effectively blocking liquid leakage even under shaking, squeezing or temperature fluctuation.

This exquisite all-plastic matching structure effectively isolates external air, dust and bacteria, inhibiting liquid oxidation and deterioration to prolong product shelf life. Boasting safe food-grade materials, elegant rounded modeling and practical leak-proof performance, this 200ml round shoulder bottle is highly compatible with mild plant-based skincare products, standing out as a cost-effective and versatile packaging solution for mainstream beauty brands’ toners and hydrosols.
