100ML round-shoulder bottle（SF-57D6）

This refined 100ml cosmetic bottle features exquisitely rounded shoulder lines that deliver a soft, smooth and integrated silhouette. Different from rigid angular bottle designs, its natural curved shoulder creates a gentle, modern and premium aesthetic, perfectly aligning with the minimalist and elegant styling trends of contemporary skincare packaging. Boasting a standard 100ml capacity, the container achieves an ideal balance of compact portability and practical storage capacity, well suited for daily home skincare routines, commercial shelf displays and on-the-go travel use. The sleek and versatile bottle body presents a clean high-end look that adapts to diverse brand positioning and visual design styles.

This bottle is fitted with a premium anodized aluminum flat cap with a professional multi-layer matching structure for stable sealing performance. The outer shell is made of high-quality ALM aluminum material, which features delicate metallic luster, outstanding wear resistance, oxidation resistance and anti-fading properties, greatly enhancing the overall packaging grade and texture. It is paired with a durable PP threaded tooth cover that ensures precise thread engagement, tight connection and excellent structural stability. Equipped with a standard sealing gasket and a high-toughness PE inner plug, the cap assembly forms a fully enclosed leak-proof system. This scientific structure effectively blocks external air, dust and moisture, preventing liquid volatilization, leakage and ingredient oxidation to maintain the freshness and activity of internal skincare contents.

Crafted with cosmetic-grade safe materials, this bottle is exclusively designed for low-viscosity water-based skincare formulations. It serves as an ideal packaging container for facial toners, pure floral waters, soothing essences and other similar liquid skincare products. All components in direct contact with liquids are non-toxic, odorless and skin-friendly, complying with global cosmetic safety regulations. The smooth bottle surface supports various personalized customizations including screen printing, hot stamping and label branding. Combining elegant rounded shoulder aesthetics, high-grade metallic texture, reliable sealing performance and wide applicability, this 100ml bottle is a timeless and cost-effective packaging solution for skincare brands.
