Why Bag on Valve Filling Becoming a Trending in Deodorant Spray

2025-03-11

Compared with traditional dedorant spray filling machine, bag on valve deodorant filling machine is more safety, this article litsed the advantage of bag on valve filling machine which used in deodorant spray. It will help you to know the trend in deodorant spray.

Deodorant sprays have long been a favoured product in the personal care sector, bringing freshness and confidence to people. As technology continues to advance, the way deodorant sprays are produced has changed significantly, with traditional aerosol line production facing the challenge of bag on valve deodorant sprays produced on BOV filling lines.

From material

Aerosols typically use LPG as propellants. This is flammable, and to ensure safety, there are strict restrictions on the formulation of the contents. Many ingredients that are beneficial to the skin but chemically active cannot be added, like some natural plant essential oils, although they have a unique aroma and skincare efficacy, they are difficult to apply because they may react with the propellant or affect the stability of the product, which greatly restricts the innovation and optimisation of the product formulation.

But BOV packaging places the contents and propellant in separate chambers without contacting each other, which makes the content formulation more flexible. More natural and efficient ingredients can be added, such as high concentration of plant extracts, active skin care factors, etc., which not only enhances the quality of the aroma, but also achieves multiple effects such as moisturising and soothing the skin.

From production

Aerosol filling requires an explosion-proof environment, and in the event of an accident, the consequences are unimaginable.

For the BOV filling line, it is relatively simple to operate and does not require an explosion-proof environment. First fill air through under cup which between the bag and bottle, and then fill the material into the bag, reducing the operational difficulties and safety risks, while improving the filling accuracy and production efficiency.

From environmental

The traditional aerosol propellants have a destructive effect on the ozone layer. Early use of chlorofluorocarbons (CFCs) propellants, has been proved to be one of the main culprits of the hole in the ozone layer, although it is now gradually replaced by hydrochlorofluorocarbons (HCFCs) and hydrofluorocarbons (HFCs), but still has a certain negative impact on the environment. Moreover, aerosol cans are difficult to recycle and become solid waste when discarded, further aggravating the environmental burden.

Compared with aerosol filling line, the propellant of the BOV deodorant spray more use of air, nitrogen and other gases, these gases are non-flammable, harmless, non-destructive to the ozone layer, in line with the current concept of environmental protection. Moreover, the outer can and BOV is relatively single, more convenient for recycling and classification processing, reducing the pollution of the environment.

Conclusion

Although the traditional aerosol line production of deodorant spray has a certain market base, but because of its own limitations, in product innovation and environmental protection and other challenges. BOV deodorant spray by virtue of the advantages of BOV packaging production, in terms of content innovation, production convenience and environmental protection and other aspects to stand out, is gradually becoming the new favourite of the deodorant spray market, leading the industry in a new direction.
