15g 30g 50g 100g Round PS Double Wall Airless Pump Face Cream Jar New Design

Key Components

• Outer Jar & Cap: Made of PP for its durability, chemical resistance, and excellent surface for printing and finishing. Often made opaque to protect light-sensitive ingredients.

• Piston/Diaphragm: The moving floor of the container. Made from flexible, impermeable materials like LDPE or specialized plastics.

• Pump Mechanism: The internal pump housed under the dispenser head.

• Base: Often has a small hole or valve that allows air to enter behind the piston (not into the product chamber) to equalize pressure and allow the piston to rise smoothly.

  

  

  Advantages of PP Airless Jars

  1. Superior Product Preservation (The #1 Benefit):

     • Airless: Prevents oxidation, which can degrade active ingredients like Vitamins C and A (retinol).

     • Contamination-Free: Prevents bacteria, dirt, and fingers from contaminating the product, making it more hygienic and extending its shelf life.

     • Protects Volatile Ingredients: Seals in fragrances and other volatile compounds.

  2. 100% Product Evacuation:

     • The piston pushes up all the product until it is completely empty. This reduces waste and allows consumers to use every last bit, which is crucial for high-end, expensive formulations.

  3. Dosage Control:

     • Dispenses a consistent, measured amount with each press, preventing overuse.

  4. Premium Consumer Perception:

     • The innovative mechanism, combined with a high-quality feel, conveys value, efficacy, and scientific advancement, which justifies a higher price point.

  5. Material Safety: PP is known for being a safe, stable, and chemically resistant plastic, making it ideal for cosmetic formulations.
