100ml triangle glass bottle（SF-217S4）

This 100ml triangular cosmetic bottle is a trendy and functional packaging solution tailored for water-based skincare products, including facial toners, pure floral hydrosols, and other mild hydrating skincare liquids. Featuring a unique three-sided triangular bottle body, it breaks the traditional round and square bottle stereotypes on the market, presenting a stylish, three-dimensional and distinctive visual effect. The innovative triangular shape delivers strong recognition and differentiated brand display effects on retail shelves, greatly attracting consumers’ attention. With a compact 100ml standard capacity, it is perfectly optimized for portable use, ideal for daily skincare, business trips, travel and outdoor outings, balancing practical daily use and lightweight carrying demands.

The bottle is matched with a high-quality full-plastic flat top cap, adopting a multi-layer composite assembly structure with premium classified materials to ensure excellent durability and reliable sealing performance. The outer flat cap is made of high-rigidity ABS material, which features superior hardness, wear resistance and anti-deformation performance. It can effectively avoid cracking and damage during transportation and daily twisting, and supports various customized surface treatments such as matte frosting, glossy finish, electroplating and color spraying, providing diverse personalized design options for cosmetic brands.

Equipped with a food-grade PP inner lining, the cap possesses excellent chemical stability and corrosion resistance. It can withstand long-term contact with plant extracts, mild alcohol and other conventional ingredients in toners and pure hydrosols, effectively preventing chemical reactions and harmful substance precipitation to ensure the safety and purity of internal skincare liquids. Meanwhile, the matched PE inner plug and PE gasket work together to form a precise and tight sealing system. The flexible PE materials fit the bottle mouth closely, filling all gaps thoroughly to achieve outstanding leak-proof effects.

This professional sealing structure effectively prevents liquid leakage caused by shaking and extrusion, and isolates external air, dust and bacteria to slow down liquid oxidation and deterioration, extending the product shelf life significantly. Combining unique triangular aesthetics, safe food-grade materials and stable functional performance, this 100ml bottle is a versatile and high-cost-performance packaging option, perfectly suitable for mass packaging of mild plant-based toners and hydrosols for skincare brands.
