How the Bag-On-Valve Works

The Bag-On-Valve (B.O.V.) is a barrier packaging technology for liquid or viscous products. The product is completely separated from the eco-friendly air or nitrogen propellant. This separation keeps the product pure. B.O.V. packaging is 100% recyclable and offers both convenience and reliability for the consumer.

Typically B.O.V.’s are used in aluminum cans with a one inch opening for crimping the valve which is welded to a foil based packaging bag with multi-layer film laminate. Once the valve has been crimped compressed air or nitrogen is filled into the area between the bag and can. This process is called under the cup gassing and keeps the product and propellant separate at all times.

Bag On Valve Technology

Are you looking for a packaging solution for your aerosol products? such as cosmetic and beauty products, food products, pharmaceutical products, fire extinguisher etc. Or you just tired of using traditional aerosol packaging technology? Then why not try to use bag on valve technology to fix your packing issues?

Reasons?

1. Better Quality Of Finished Aerosol Products.

The finished aerosol product with bag on valve technology has better spray effect, mainly reflected in the wider spray range, the spray molecular weight is more even and finer, and it is easier to be absorbed.

2. No Limited Substances.

The gas and the material in the traditional aerosol spray technology must be mixed, so the choice of the substances is limited. The gas and substances in the bag on valve packaging technology are separated, there would be no limit for the used material.

3. Safety Guarantee.

The most commonly used gas in traditional aerosol spray packaging is propane, which is very easy to explosive in high temperature or high pressure environment.

Therefore, the traditional aerosol spray packing can not be taken on the plane. The gas in the bag on valve package is usually nitrogen or compressed air, these kind of gases are safe.

4. More Environmentally Friendly.

The gas and material of the bag on valve package are separated. The material is filled into an vacuum bag, but the compressed air is filled between the bag and the cans.

The compressed air squeeze the bag to spray the material, thereby avoiding pollution caused by direct contact.
