What is Bag On Valve？

The Modern Standard for Pure Dispensing

Sac sur valve (BOV) is a superior barrier packaging technology that completely separates your product from the propellant.

Unlike traditional aerosols, the product is sealed inside a multi-layer FDA-approved pouch, while compressed air or nitrogen fills the space between the bag and the can. This ensures the formulation never touches the propellant, guaranteeing 100% pureté and extending shelf life.

Why Brands Choose FANXUN BOV:

360° Application: Sprays continuously at any angle, même à l'envers.
99.9% Evacuation: Consumers get every last drop—zero waste.
Écologique: Powered by clean air, not flammable chemicals.

Bag On Valve Aerosol Filling Process

STEP 1

Precision placement of the BOV system into the can.

STEP 2

Injecting compressed air or nitrogen into the can.

STEP 3

Hermetically sealing the valve to the can body.

STEP 4

Forcing the liquid product into the bag through the valve stem.

STEP 5

100% leakage detection for safety assurance.

STEP 6

Fitting the nozzle and overcap for the final finish.

Bag On Valve Vs Aerosol

	Traditional Aerosol	BOV (Sac sur valve) Technologie
Scellage	Poor sealing; no barrier between product and gas.	Protection supérieure; 4-layer vacuum bag isolates the formula.
Pureté	Propellants mix with ingredients; purity is compromised.	Ingredients are separated from propellants; 100% pure formula.
Atomisation	Inégal, coarse spray.	Continu, brume fine (Nano-atomization).
Commodité	Must shake before use; requires repeated pumping.	No shaking needed; continuous spray anytime.
Angle de pulvérisation	Upright use only.	360° All-angle spray (même à l'envers).
Utilization	High residue and waste.	>98% Product evacuation.
Noise Level	Loud hissing sound.	Silent / Whisper-quiet.
Sécurité & Écologique	Flammable propellant expelled with product.	Propellant stays in can; Ininflammable & Écologique.
Propergol	Hydrocarbures (GPL).	Compressed Air or Nitrogen.
Coût	Économique / Low Cost.	Prime / Coût plus élevé.
Filling Process	Product first, then propellant.	Propellant first, then product.
