40ML aluminum bottle（JH-42Y）

Crafted with high-quality glass, the bottle body ensures excellent chemical stability— it does not react with the active ingredients in serums (such as hyaluronic acid or vitamin C) or essential oils (like lavender or tea tree oil), effectively preserving product purity and efficacy. What sets it apart is the aluminum sleeve that covers the outer surface of the glass body: this sleeve serves two key purposes. First, it acts as a robust protective layer, significantly reducing the risk of breakage during transportation, storage, or daily use, which is crucial for fragile glass containers. Second, it offers extensive customization potential—supports processes like anodizing, silk-screen printing, hot stamping, or laser engraving, allowing brands to add logos, product information, or unique patterns to align with their visual identity and enhance market competitiveness.

Complementing the bottle body is a well-engineered dispensing system, starting with an electrolytic aluminum dropper. This dropper features a three-layer structure: an inner PP (polypropylene) lining that meets food-grade and cosmetic safety standards, ensuring no harmful substances leach into the product; an aluminum oxide shell that boosts durability and a sleek, premium look; and a 20-thread trapezoidal NBR (nitrile butadiene rubber) cap that provides airtight sealing to prevent liquid volatilization and contamination. Paired with the dropper is a 20# guide stopper made of PE (polyethylene), which not only facilitates smooth insertion and removal of the dropper but also adds an extra layer of sealing to maintain the product’s freshness over time.

With its balanced 40ML capacity—ideal for both travel-sized convenience and regular use—combined with reliable protection, customizable design, and safe, precise dispensing, this bottle stands out as a versatile and attractive choice for brands looking to elevate their serum or essential oil packaging.
