In BOV, the product is in a bag separate from the propellant, which prevents alteration. This is because the technology behind this formulation does not require mixing with the gas for the product to be dispersed.

The bag on valve aerosol packaging does not require pumping to spray—press the button to get a continuous spray. This differentiates it from the traditional methods requiring you to shake and assist the product before dispensing.

As long as the product viscosity is low to allow passage through the valve, you can fill this kind of bag with your products.

Stainless steel is one of the best metals for making a pressurized can as it requires no coating and is highly inactive. Due to its sterilized heat, epoxy coating is the best to use. These cans are very expensive, although they last longer and do not rust.

The cans are suitable for refilling aerosol products, although the aluminum type costs more but is much safer. Tin cans are prone to rust and therefore tend to cost less.

Plastic is slowly gaining popularity amongst cosmetic and home cleaning products industries. They are, however, highly permeable to vapor, thus increasing oxidative degradation in the formulation.

With bag on valve, you can use up to the last drop of your product. There is no need to tilt the can to a specific side when using BOV technology.

Like stainless steel containers, aluminum is very light in weight. They are used in disinfectants, air fresheners, and insecticide sprays industries.

Bag on valve aerosol packaging technology is an example of a product that meets environmental safety requirements while giving you value for your money. This is because the valve in the bag allows you to use your product 100% and without shaking before use.

BOV aerosol packaging is suitable for liquids and any viscous product. They are also improved to handle oxygen-sensitive and sterilized products.

Of course to determine the image location, only a pair of incident and reflected rays need to be drawn. It is customary to select a pair of rays that is easy to draw. Of the five pairs of incident and reflected rays in the diagram above, two correspond to the rays that are customarily drawn. In fact, they may closely resemble the two rays that were used in concave mirror ray diagrams. Recall from Lesson 3 that there were two rules of reflection for concave mirrors. They are:

Glass containers are best used when a low amount of propellant and low pressure is used. They are best used in packaging topical and MDIs, and they don’t rust. However, there are two types of glass containers: Coated and uncoated.

This is the best part of the bag on the valve aerosol packaging system. You’ll need no intense effort to press this actuator.

Throughout this unit on Reflection and the Ray Model of Light, the definition of an image has been given. An image is the location in space where it appears that light diverges from. Any observer from any position who is sighting along a line at the image location will view the object as a result of reflected light. Each observer sees the image in the same location regardless of the observer's location. As the observer sights along a line, a ray of light is reflecting off the mirror to the observer's eye. Thus, the task of determining the image location of an object is to determine the location where reflected light intersects. The diagram below shows an object placed in front of a convex mirror. Light rays originating at the object location are shown approaching and subsequently reflecting from the mirror surface. Each observer must sight along the line of a reflected ray to view the image of the object. Each ray is extended backwards to a point of intersection - this point of intersection of all extended reflected rays is the image location of the object.

Bag on valve technology is flexible! It has given industries the freedom to choose and place many forms of product in these cans. In the current world, products ranging from cooking oil to cleaning detergents can be packed in pressurized cans for effortless dispensing.

Aerosols can be packaged using containers made from different materials. They generally range from glass, metal, and plastic, speedily becoming a favorite amongst pharmaceutical and cosmetic industries.

The diagram at the right depicts a convex mirror. In Lesson 3, a convex mirror was described as a portion of a sphere that had been sliced away. If the outside of the sphere is silvered such that it can reflect light, then the mirror is said to be convex. The center of that original sphere is known as the center of curvature (C) and the line that passes from the mirror's surface through the sphere's center is known as the principal axis. The mirror has a focal point (F) that is located along the principal axis, midway between the mirror's surface and the center of curvature. Note that the center of curvature and the focal point are located on the side of the mirror opposite the object - behind the mirror. Since the focal point is located behind the convex mirror, such a mirror is said to have a negative focal length value.

While most consumers preferred traditional aerosol packaging methods due to low price, bag on valve technology maintained its stand on quality and safety.

Bag on valve packaging technology separates the product and the propellant, which protects exposure to oxygen by using an airtight pressurized can, resulting in a longer shelf life. The traditional packaging method exposes the product to more oxygen, which can make it degrade faster.

Aerosol containerdefinition

Further, in the aluminum pressurized can or bottle, a long tube spreads the valve to ensure it touches the content inside. For the product to be easily dispersed, it’s mixed with a propellant that’s vaporized as it is released. Let’s look at the different kinds of aerosol packaging.

Traditional aerosol packaging releases a lot of noise because the gas mixes with the product directly and fills the pressurized can, which is very dangerous. Again, the spray button needs exerted effort to function.

A convex mirror is sometimes referred to as a diverging mirror due to the fact that incident light originating from the same point and will reflect off the mirror surface and diverge. The diagram at the right shows four incident rays originating from a point and incident towards a convex mirror. These four rays will each reflect according to the law of reflection. After reflection, the light rays diverge; subsequently they will never intersect on the object side of the mirror. For this reason, convex mirrors produce virtual images that are located somewhere behind the mirror.

Aerosol containertypes

It includes a male and female aerosol valve, which can be used for BOV packaging. The only difference is the filling speed and cost, which is higher in females than in males.

The BOV aerosol packaging technology does not release gas due to the isolation of gas material. It is gas propellant safe, and the pressurized can has compressed air that doesn’t have explosive components, meaning it is highly safe when performing.

The bag on valve aerosol packaging technology has an even and continuous fan-shaped spray. Again, it does not harbor sediments, so it can be sprayed at any angle because the valve is long and touches the bottom of the pressurized can.

These cans look classy and unique, which increases brand recognition. The products are also clean and free from contamination because you don’t touch the product even when holding the pressurized can.

The image in the diagram above is a virtual image. Light does not actually pass through the image location. It only appears to observers as though all the reflected light from each part of the object is diverging from this virtual image location. The fact that all the reflected light from the object appears to diverge from this location in space means that any observer would view a replica or reproduction when sighting along a line at this location.

The BOV technology ensures that the bag is four-layered to extend the product’s shelf life. The product also doesn’t come into contact with any oxygen, which can help extend its shelf life as well.

Components of aerosols

If you’re a beginner, you might wonder about the major differences between traditional and bag on valve technology. We’ve detailed six of them here. Read on:

Bag on valve packaging technology allows you to empty the pressurized can to the last drop with ease. It provides up to 100% product emptying because the propellant is separated from the product, thus exerting pressure on the product bag and fully emptying it.

Bag on valve technology is based on advanced filling machines, which are automatic and semi-automatic for you to choose from. Since these filling machines are much improved, they lead to different production effectiveness in terms of design and manufacturing.

The traditional aerosol packaging method has a poor spray effect and a large impact force, making it difficult to be absorbed. The pressurized can harbors sediment, therefore, necessitating shaking before use. You’ll need to press the release button several times during use and maintain a specific horizontal angle when holding the pressurized can.

However, consumer needs are now on par with bag on valve packaging technology — safety first! This has therefore increased the demand for this type of product, and it has a variety of benefits to both the consumer and the business people selling it.

On the other hand, the traditional aerosol packaging method mixes the product with the propellant. As a result, the propellant gets depleted faster, leaving the unused product in the bottle. This means chances of wastage when using traditional aerosol packaging methods are very high.

Unlike traditional aerosol packaging technology, where the propellant is mixed with the product when spraying, the BOV technology dispenses the product only. This is because the bag is soldered to the aerosol valve and dipped inside the aluminum or steel pressurized can.

In the diagram above, the second and third (from the top) blue incident rays exemplify these two rules of reflection for convex mirrors. Using this pair of incident and reflected rays will greatly simplify the task of drawing ray diagrams and determining the location of images. In the next section of this Lesson, such ray diagrams will be shown.

Lesson 3 focused on the reflection of light by concave mirrors and on the formation of images by this reflected light. In that lesson, it was shown that concave mirrors can produce both real and virtual images, depending upon the object location. In Lesson 4, we will follow a similar pattern of inquiry for convex mirrors: investigating how convex mirrors reflect light and produce images. We will also investigate how ray diagrams can be used to estimate image location, size, orientation, and type for objects placed in front of convex mirrors. Finally, we will use the mirror equation to calculate numerical information about image distance and size if given an object distance, object size and focal length.

When spraying, you get an even and fine mist because the BOV technology allows good aerosol formulation and valve. The fineness of the spray lets it be absorbed fast and completely.

When bag on valve was first introduced, consumers thought it was expensive and not meeting the basic requirements of aerosol packaging. Later on, the narrative changed, and the consumers are now searching for products in terms of safety and not cost.

Bag on valve packaging technology can pack viscous and liquid products, including oil, car cleaning foam, insecticide, etc.

Bag on valve has no noise when spraying because the propellant controls air movement around the pressurized can or bag with the product.

The product is then put in the bag, and the propellant is placed in the remaining space between the bag and the walls of the can. This allows the product inside the bag to be squeezed by the propellant when you press the actuator.

On the other hand, traditional aerosol packaging mixes with gas agents, which are released together when you press the spray button. These gases are highly flammable and can cause explosions and burning, making the packaging unsafe for the environment.

Because of this technology, the aerosol packaging is suitable for liquids, creams, and gels that need to be pure. However, BOV technology is not used for products that settle at the bottom and thus require shaking before use.

Aerosol containerexample

They are easily decorated and can be used for different aerosols, including cleaning detergents, disinfectants, and inhalation aerosols. The material is light and suitable for home use and pharmaceutical products, especially those used on the go.

The many issues that the traditional aerosol packaging method had have been resolved by the BOV system, marking major growth in the packaging industry. Below are the common products that use bag on valve aerosol packaging technology.

Since its development in 1941, aerosol packaging has been in use throughout the years. Companies in the medical, pharmaceutical, cosmetics, and home cleaning field have been using aerosols in their packaging.

This is the new and trending technology for packaging aerosols. It consists of aerosol valves, a vacuum bag, an aluminum pressurized can, an actuator, and caps.

Aerosol containerparts

The propellant and the material agent are packaged separately in different containers. This eases formulation and ensures that when in use, it does not release the propellant, thus reducing environmental and safety impact, making it a safe packaging technology.

Metal containers are the most popular in aerosol packaging industries. The cans are light and last longer compared to glass and plastic, which risks breaking. They come in three different types:

The pressurized can is coated by an electrolytic process using three sheets which are joined using the soldering method. They are then coated with epoxy or vinyl to prevent further reaction due to the heating process. The cans are mainly used for packaging topical aerosols.

Traditional aerosol packaging methods limited the type of products you could place in such pressurized cans because of product safety. This is due to the mixing of the propellant and the product, which causes contamination.

Aerosol products are easy to use throughout the household and even when on the go. The most common products are air fresheners, disinfectants, and hairsprays. The containers come in aluminum bottles or cylinders that distribute the product inside in a foam or mist spray. You start this process by pushing a button or valve.

Bag on valve technology is used in packaging many other products, and it’s widely used. Besides, it’s the best because it does not emit gases, thus protecting the environment, unlike the traditional packaging methods, which emit gases with every dispensing.
