What is bag aerosol valve?
Bag on valve technology is a new trendy packaging technology for aerosol products. It is a multi-protective packaging system consisting of aerosol valves, vacuum bag, tin cans or aluminum cans, actuators, caps.
How does a bag valve work?
The Bag-on-Valve system is built around an aerosol spray valve welded to a sealed poly-laminated aluminum bag. When filled with product, the bag is placed inside a tinplate or aluminum can that is then pressurized with compressed air or nitrogen propellant as valve is fitted under pressure.
Is BOV considered aerosol?
As a pressurized packaging consultant, I can assure you all B.O.V.’s are pressurized systems, the same as aerosol products are pressurized systems, but all B.O.V.’s are NOT Aerosol! uses liquid gas propellants (Hydrocarbons) to compress the B.O.V.
What are some examples of aerosol cans?
If a can is designed to spray out its contents, it is an aerosol can. Examples include spray paint, hair spray, room deodorizers, and many more.
How does an aerosol can valve work?
The liquid product is poured into the can. Then, after the can is sealed, the gas is pumped in at high pressure which causes it to push down on the product. When you press down on the button, the valve opens and reduces the pressure at the top of the can.
What does bag on valve mean?
The Bag-On-Valve (B.O.V.) is a barrier packaging technology for liquid or viscous products. 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.
How are aerosol cans filled?
Some cans, such as spray-paint cans, have a ball bearing inside. If you shake the can, the rattling ball bearing helps to mix up the propellant and the product, so the product is pushed out in a fine mist. When the liquid flows through the nozzle, the propellant rapidly expands into gas.
What’s in aerosol cans?
In the United States, the most common propellants are naturally occurring hydrocarbons. A few products, about 10% of today’s aerosols, use compressed gases like carbon dioxide and nitrous oxide as propellants. The final element is the container, which is usually a steel or aluminum can.
Why are aerosols bad?
One of the worst aerosol environment effects is air pollution. VOCs, contained in traditional aerosol cans affect the environment by constantly contributing to the formation of ground-level ozone.
What makes aerosol cans spray?
The air inside the top of the bottle is at higher pressure than the air in the tube, so it pushes down on the liquid. The liquid is forced up the tube toward the pump mechanism. The liquid leaves as a fine mist of aerosol spray.
Why do you have to shake aerosol cans?
A few aerosols need to be shaken before you use them. This is to make sure that the product and the propellant are well mixed. Many propellants aren’t miscible in the product. Without a good shake, you’ll be left with a pool of propellant when the product runs out; this doesn’t make very good body spray!
How are aerosol cans pressurized?
Will aerosol cans explode in checked luggage?
Aerosols. Aerosol toiletries such as hairspray or mousse are exempt from the TSA ‘s ban on aerosol products in carry-on and checked baggage. The TSA notes that passengers can bring such products on a plane in “limited quantities,” but an exact number is undefined. Travelers are probably safe with a couple of cans,…
Can you carry aerosols in checked baggage?
Hairsprays contained in aerosol cans are not restricted in checked in baggage. It is only important to remember that the quantity should not exceed three ounces and the container should be packed in a plastic bag with a zip seal.
What not to pack in checked luggage?
Important Documents. The last thing you want to do is leave your passport and travel documents in the bag that gets packed away on the plane.
Can You pack Hairspray in checked luggage?
Though plastic bags with zip locks are not mandatory for packing hairspray in checked-in luggage, you can always use them to prevent accidental leaks. Do not place the hairspray in the outside pockets of the checked-in luggage; there is every chance that the container may be damaged when the luggage is being handled.
