Packaging Technologies ‘Environmentally Friendly’ Aerosol solution

Packaging Technologies, KP Aerofill of Davenport, IA, USA has released a new pressure crimper designed specifically for BOV (bag-on-valve) technology, which provides aerosol customers with a totally green environmentally friendly production process.

The BOV system separates the product from the propellant with a hermetically-sealed, multi-layered laminated pouch. The BOV system is designed  for compressed air or nitrogen as a propellant, which does not produce any volatile organic compounds (VOCs), making it the most environmentally friendly production process, as compared to traditional technologies, that use propane or butane and eliminates the need for flammable propellants. The process is suitable for the filling of both liquids and higher viscosity products and can be used with standard actuators and aerosol cans.

The bag-on-valve is widely used in the packaging of cosmetics, pharmaceutical, household, pet care and other products that require complete separation between the product and the propellant.

Consumers benefit from:-

• 100% product evacuation

• Longer shelf life with less preservatives

• Even and controlled spraying pattern for optimal results

• No pumping motion necessary as on trigger sprayers

• Can be used at all angles

• Reduced spraying noise

The new pressure crimper technology makes it possible to pressurize under the cup of the BOV and fill nitrogen or air at low pressures before crimping the valve in place. The crimper heads have their own individual pressure transducers that monitor the pressure in the head and the container during pressurization, automatically rejecting the product, if the preset parameters are not achieved. The crimp depths and diameter adjustments have indexed, external, tool-less mechanisms that are exact, which save time for size changeovers. Older under the cup fillers can also be retro fitted in order to benefit from this technology.
