The Difference Between Tube Valve Aerosol Packaging and BOV Aerosol Packaging

While the two may seem similar, the differences are huge: the wrong choice can lead to spoiled contents, safety hazards, and even failure to pass compliance testing. Next, we break down the core differences from structure, safety, stability to application scenarios to help you match the most suitable solution.

When developing a new aerosol product, choosing the right packaging is key - but are you stuck: should you use Tube Valve or BOV aerosol packaging?

1.Structural composition  

Tube Valve Aerosol Packaging:

Consists of a container, valve system, and propellant and contents together form a closed space. The contents and propellant are mixed and stored in the same container.

Bag on Valve Aerosol Packaging:

Consisting of two independent containers, one container is used to store the contents, the other container stores the propellant, and the two are mixed and sprayed out at the time of use through a special valve structure.

2.Working Principle

Tube Valve Aerosol Packaging:

Relying on the pressure of the propellant itself, the mixture of contents and propellant is sprayed out directly after opening the valve. Propellant in the whole process both to provide pressure power, and direct contact with the contents.

Bag on Valve Aerosol Packaging:

In use, the contents and propellant are mixed in a specific ratio and sprayed out through the control of a valve system. The pressure of the propellant is primarily used to propel the contents to be ejected, rather than mixing with the contents over time.

3.Safety

Tube Valve Aerosol Packaging:

Since the propellant and the contents are always mixed together, there may be some safety risks under certain circumstances. For example, if the container is affected by external factors such as high temperature and impact, it may lead to excessive pressure and explosion and other dangerous situations.

Bag on Valve Aerosol Packaging:

Relatively safer. Because the contents and propellant are stored separately, the risk of possible chemical reactions due to mixing of the two is reduced. Even if the container is subjected to a certain degree of external influence, it is less likely to have serious safety accidents.

4.Product quality and stability

Tube Valve Aerosol Packaging:

The propellant may have a certain effect on the contents, such as affecting the chemical stability of the contents, taste, color, etc.. Long-term storage process, there may be content and propellant interactions that lead to product quality degradation.

Bag on Valve Aerosol Packaging:

As the contents and propellant are mixed only before use, the original nature of the contents can be better maintained and the product quality is more stable. The proportion and effect of spraying can be more accurately controlled to ensure consistent performance of the product each time it is used.

5.Application areas

Tube Valve Aerosol Packaging:

Relatively safer. Because the contents and propellant are stored separately, the risk of possible chemical reactions due to mixing of the two is reduced. Even if the container is subjected to a certain degree of external influence, it is less likely to have serious safety accidents.

Bag on Valve Aerosol Packaging:

Mainly use for water base aerosol product，More often used in the field of product quality and safety requirements of high quality, such as pharmaceutical aerosol, high-grade cosmetics aerosol

In summary, Tube Valve Aerosol Packaging is a cost-effective choice for everyday, low-risk products, while BOV Aerosol Packaging is the go-to for products demanding safety, purity, and long-term stability—especially in pharmaceuticals, cosmetics, and food-grade applications.
