100ml triangle lotion bottle（SF-198S4）

This premium 100ml cosmetic triangular bottle is a distinctive and functional packaging solution tailored for mild water-based skincare products, including facial toners, pure floral hydrosols and other hydrating liquid cosmetics. Differing from conventional round and square bottle designs, its unique triangular bottle body creates a three-dimensional, stylish and modern visual effect, delivering outstanding shelf differentiation and brand recognition. The sleek, smooth bottle walls present a minimalist and premium texture, while supporting diverse personalized craftsmanship such as screen printing, hot stamping, labeling and frosting, allowing brands to showcase brand logos, product information and unique styling freely. The compact 100ml capacity strikes a perfect balance between daily household use and lightweight portability, well-suited for daily skincare, business trips, travel and outdoor scenarios.

This bottle is equipped with a high-performance full-plastic flat top cap, adopting a multi-component composite material structure to integrate aesthetic appearance, structural durability and reliable sealing performance. The flat outer cap is manufactured from high-rigidity ABS material, featuring excellent hardness, scratch resistance and impact resistance. It effectively resists deformation, cracking and wear during daily twisting, storage and long-distance transportation, and supports customized surface treatments including glossy finishing, matte frosting and color spraying to meet diverse brand packaging design needs.

Fitted with a durable PP inner lining, the cap assembly possesses excellent chemical stability and corrosion resistance. It can maintain stable performance during long-term contact with plant extracts, mild alcohol and other common ingredients in toners and hydrosols, avoiding chemical reactions and impurity precipitation to protect the purity and activity of internal skincare liquids. Cooperating with the lining, the matched PE inner plug and PE gasket form a precise, tight sealing structure. The flexible PE materials fit the bottle mouth closely to eliminate gaps thoroughly.

This professional sealing system provides excellent leak-proof performance, effectively preventing liquid leakage caused by shaking, extrusion and temperature changes. It also isolates external air, dust and bacteria, slowing down liquid oxidation and deterioration to extend product shelf life significantly. Combining innovative triangular aesthetics, safe skin-friendly full-plastic materials and stable practical functions, this 100ml bottle is a versatile and cost-effective packaging option, ideal for formal packaging and mass production of various gentle hydrating skincare toners and pure hydrosols.
