Introduction

Over the years, the market has seen a rapid rise in Bag on valve technology, especially in Household care items, pharmaceuticals, and personal care products. The system features a significant improvement over the traditional spray method.

When using it, you are sure that your product is fully protected, and you can discharge it at any time. It also uses non-flammable gas, which guarantees more safety. For more insights about it, continue reading this guide.

The History of Bag on Valve Technology

The initial spray-can was made in 1927 by Erik Rotheim, a chemical engineer from Norway. Other people started researching the idea, such as Julian Khan, but none was able to entirely develop the concept. However, a few years later, the system revived thanks to Willian Sullivan and Lyle Goodhue, who helped modernize the technology.

In 1982 the first bag on valve filling design patent was developed in Europe. It consisted of a flexible multi-layer bag, welded onto a valve. The gas-product was then filled in the pouch, which led to the growth of many present-day commercial aerosol products.

Bag on Valve Technology (BOV)

The bag on valve technology is a barrier packaging system utilized in viscous and liquid products. You will love the technology’s safety level since it completely separates the propellant gas and the material agent. It helps minimize the complexity of the formula, thereby reducing the impact on the environment and upholds safety standards.

You can use the BOV system with aluminum cans, leave a one-inch opening to the left to crimp the valve, and then wield it to a multi-layer lamination bag. Once the valve gets compressed, nitrogen cis usually filled between the can and the pouch. Separation of the products ensures it remains pure, and you don’t need to use preservatives.

How It Works

You may be thinking that the system works by just pressing the actuator, but there are more mechanics involved.

The pressure is a critical element in the design of the bag on the valve filing system. Compressed air or nitrogen is used as a propellant gas inside the canister at about 0.3 to 0.4Mpa. Further, after filling the formula liquid, the pressure levels can get to about 0.6 to 0.7Mpa to squeeze the bag tightly.

When using it, you need to press the actuator, which acts as a trigger to open the channel that passes the formula via the stem. The result is a fine mist spray that can continue as long as you press the activator until the liquid runs out. You can hold it at any angle since the bag gets pressure from every side.

To stop the spray, you just lift your finger from the actuator, leading to the channel’s closure. Further, when your bag is empty, the gas still stays inside.

Components of the Bag on Valve System

A finished product that utilizes the BOV technology may make you think that it consists of a simple system. However, it comprises several complementary components to bring out the final result as discussed below:

Aerosol Can

You can use two can varieties during bag on valve filling, either tin or aluminum type. The latter appears a bit costly, but it’s much healthier and cleaner than the former. The tin can easily rust, thereby affecting your aerosol product’s quality standards after a while.

Aerosol Actuator

The actuator acts as the activator to release the contents from the can. It’s the most used feature on the BOV packaging because you need to press it to eject the aerosol. Products from signature filling company come with the actuator conveniently positioned for more comfortable use.

Aerosol Valve

The system includes both the male and female aerosol valves and can be used effectively on the packaging. However, the latter is more expensive but has a faster filling speed than the former.

Vacuum Bag

Bag on Valve Filling Process

Filling aerosol products using the BOV procedure is a little bit different compared to other methods. The steps involved include;

Placing the Valve and Bag into the Can

The initial step is inserting both the bag and the valve in the can, which you can manage manually. Alternatively, you can use a feeding machine, especially when working with many products, but the cost is much higher.

Under Cup Gassing and Crimping

The most important part of the bag on the valve filling process is under cup gassing since an error will lead to poor results. You need to crimp the valve then fill the propellant-gas into the cans. Note that you should not get any element into the bag because the material and gas should be separated. Therefore, your speed and accuracy levels are vital at this stage.

For more efficiency, you can try using the automatic BOV aerosol filling machine for the entire process. It helps you get a high quality finished product at a faster rate.

Filling Contents into the Vacuum Bag

The next crucial task is getting materials into the pouch, which you also need a machine to make work easier.
