Vacuum negative pressure bottom fill perfume bottle

Vacuum negative pressure bottom-fill perfume bottles are upgraded, high-end, reusable fragrance packaging products, specially developed to solve the oxidation and fragrance deterioration problems caused by air contact in traditional perfume sub-bottles. Unlike ordinary press-fill bottles, this upgraded version adopts an integral vacuum sealing process and an optimized negative pressure pipeline structure, which can discharge almost all internal air during filling and maintain a long-term sterile and oxygen-free storage environment inside the bottle. Traditional top-filling and ordinary bottom-filling bottles will inevitably leave a small amount of air in the cavity, leading to slow oxidation of perfume, fading of top notes, and turbidity of the liquid after long-term placement. The vacuum negative pressure model completely eliminates this problem, realizing 100% air-isolated fragrance storage. Made of thickened high-borosilicate glass and an anti-corrosion stainless steel pump core, the bottle body is pressure-resistant, drop-resistant, and corrosion-resistant, compatible with all types of perfume, cologne, and fragrance mist. It fully complies with global sustainable packaging standards and aviation travel carrying regulations, and is widely used in brand sample customization, high-end gift sets, and cross-border retail. It is the most cost-effective high-end packaging choice for modern fragrance brands.
