Continuous spray that works at any angle
InSpec Solutions runs bag-on-valve and aerosol start to finish, including air-free continuous spray. Your formula stays clean, sprays upside-down or sideways, and never gets handed to a third-party filler, so you don't have to worry about who actually makes it.
A sealed bag inside the can keeps product and propellant apart
Product never touches propellant
In a traditional aerosol, the product and the propellant mix in the same chamber. In a BOV, the product fills an inner bag and the propellant surrounds it. They never touch. The result: no propellant in the formula, cleaner chemistry, and a spray that works upside-down, sideways, or any angle.
That air-free seal also means longer shelf life, better preservation of active ingredients, and no oxygen degradation, which is why BOV dominates in pharmaceutical topicals and premium sunscreen.
Higher usage, higher price point
Brands that move from pump or lotion to continuous spray report higher usage rates, which means customers finish the product and repurchase sooner. Continuous-spray formats also carry a $1-4 retail premium over equivalent pumps. The math favors the switch.
The hard part is finding a manufacturer who can run the format. Most can't, and the ones who can are usually at capacity with their existing clients.
How a bag-on-valve unit gets filled
Can filling
Product is filled into an inner bag inside the can, completely sealed from the propellant from the start.
Valve crimping
The valve is crimped to the can under controlled pressure, creating the hermetic seal that makes air-free dispensing possible.
Gas injection
Compressed gas (nitrogen or compressed air) is injected between the can wall and the bag, creating the pressure that drives consistent spray.
QC & fill-weight check
Every unit is weighed and checked for spray consistency. Out-of-spec units are pulled before they leave the line.
Eight categories we run on the BOV line
See formula library →One of the few US manufacturers running bag-on-valve commercially
There are thousands of contract manufacturers in the US. Only a small number run commercial BOV lines, and most of that capacity is already committed. A brand trying to enter continuous spray often has nowhere to run it.
InSpec has run BOV alongside everyday formats since before spray SPF became a category. If you're ready to move, we can talk timelines and minimums.
