BOV (Bag-on-Valve)

img

Novopharm is a specialist in the development and manufacturing of final medical products using the Bag-On-Valve (BOV) spray technology, is an advanced packaging system and enables the dispensing of liquids, creams, gels, or foams in a more efficient, hygienic, and environmentally friendly way compared to traditional aerosol systems.

How Bag-on-Valve Technology Works

  1. Structure:
    • The BoV system consists of a flexible bag (typically laminated) inside a can, which is surrounded by compressed gas or air.
    • The product (e.g., liquid, cream, or gel) is stored inside the bag, while the pressurized gas remains outside the bag.
  2. Mechanism:
    • When the valve is pressed, the pressurized gas pushes the product out of the bag through the nozzle without mixing with the product.
  3. Key Components:
    • Canister: The outer shell containing the pressurized gas and the bag.
    • Bag: Stores the product, ensuring no direct contact with the propellant.
    • Valve: Controls the release of the product.

Bag-On-Valve technology is revolutionizing pharmaceutical packaging by enhancing product safety, usability, and environmental sustainability, making it a preferred choice for Novopharm with modern pharmaceutical applications

Advantages

  1. Preservation of Product Integrity:
    • The four layers laminate bag offers a superior barrier which eliminates the possibility of contamination, oxidation, or contact with the propellant making it ideal for products of concern.
    • Suitable for oxygen- or moisture-sensitive formulations.
  2. Hygienic and Sterile:
    • Ensures the product remains sterile throughout its shelf life, making it ideal for pharmaceuticals like wound sprays, saline solutions, and nasal sprays.
  3. Consistent Dispensing:
    • Provides controlled and uniform dosing without wasting the product.
  4. Environmentally Friendly:
    • Uses compressed air or nitrogen as the propellant, reducing reliance on harmful chemical propellants.
  5. Extended Shelf Life:
    • The sealed system minimizes the risk of microbial contamination, extending product durability.
  1. Multi-Position Use: 360 Spray from any angle; 360° actuation
    • Can dispense effectively at any angle, even upside-down, ensuring convenience for the user.

7. Minimized Residue:

    • The system allows nearly 100% evacuation of the product, reducing waste.
