The core advantages of plastic vacuum bottles
Ingredient preservation
Fully sealed design: By isolating air and ultraviolet rays, it avoids oxidation and deactivation of active ingredients (such as VC and retinol), extending the shelf life.
No backflow pollution: The one-way valve design ensures that the contents only flow out and not in, preventing bacterial invasion.
user experience Optimization
Precise dosage control: the output is about 0.1-0.3ml per press, suitable for high concentration essence, and avoid overuse.
Extreme utilization: the residual liquid rate is less than 5%, which is more economical than the ordinary face cream bottle (residual liquid 15% -20%).
Brand value enhancement
Technological appearance: Transparent acrylic+metal pump head design fits high-end cosmetics and laboratory brand tone.
Environmental premium: PETG material is recyclable, and the replacement mode can increase the repurchase rate (such as a brand's replacement repurchase rate reaching 37%).
Cost effectiveness
Production adaptability: The injection molding process is mature, and the minimum order price for 100000 pieces can be controlled between 1.2-1.8 yuan (depending on the complexity of the structure).
Transportation safety: There is no risk of glass bottle breakage, and the logistics loss rate is reduced to below 0.3%.
Advanced application scenarios
Medical art post product: The vacuum sterile environment meets the packaging standards for Class II medical devices.
High volatility essential oil: The anti volatility design can reduce the loss of volatile components such as linalool by up to 80%.
Children's products: require a press lock design (rotating unlock) to prevent accidental contact.
