20mm Bag on Valve Airless Dispensing System for Pharma & Cosmetics

Product Description:

The PureFlow 20mm Bag on Valve (BOV) system represents the pinnacle of advanced, airless dispensing technology. By completely separating your product in an internal pouch from the inert propellant gas, it ensures unparalleled protection against oxygen, contamination, and degradation. This makes it the ultimate choice for preserving the efficacy and integrity of sensitive pharmaceuticals, premium cosmetics, and even food products. The system delivers consistent, precise dosing with 99%+ product evacuation—minimizing waste and maximizing value. Its 20mm configuration offers easy integration, making it the perfect barrier packaging solution for brands that refuse to compromise on purity and performance.

Bullet Points:

• Airless Dispensing: Keeps product and propellant entirely separate, preventing contamination and preserving formula efficacy without preservatives.

• 99%+ Evacuation: Dramatically reduces product waste, ensuring customers receive full value from premium and expensive formulations.

• Oxygen-Safe Barrier: Protects oxygen-sensitive ingredients (like vitamins, peptides, live cultures) from degradation, significantly extending shelf life.

• 20mm Industry Standard: Allows for easy integration into existing production lines and packaging formats.

• Versatile Formulation Compatibility: Excellent for liquids, creams, serums, purees, and viscous products, from low to high viscosity.

• 
  

Specific Application Scenarios:

This 20mm BOV is the gold standard for products where purity, precision, and preservation are paramount:

• Pharmaceuticals & Vaccines: Ensures sterile, precise dosing for nasal vaccines, topical sprays, and sensitive medications requiring absolute purity.

• Premium Skincare: Perfect for preserving the potency of vitamin C serums, antioxidant-rich formulas, and peptide treatments vulnerable to air.

• Advanced Cosmetics: Used for high-end hair serums, scalp treatments, and leave-in conditioners that benefit from airless, waste-free dispensing.

• Food & Nutraceuticals: Ideal for oxygen-sensitive products like olive oil sprays, vitamin supplements, and baby food purees.

• Industrial & Electronic Applications: Provides pure, uncontaminated dispensing of sensitive solvents, lubricants, and coatings.
