Bag On Valves: benefits

- High impermeability: exclusive, patented valve-bag seal

4-layer (one in polyamide) film bag, valve body in POM resin: seal provides better impermeability
than with polyethylene body. The system was adopted in the late 80's for nail guns cartridges.

This positive experience led Coster to develop the BOV system for pharmaceutical and cosmetics applications.

- High drop withstand

The form of the bag is designed to enable high drop withstand. With BOV2, to increase drop test resistance, fixation of the bag was improved with the introduction of a polyethylene ring welded to the multi-layer film
at the point of juncture with the valve.

- Uses standard cans: both product & propellant filled through valve

The same machines can be used to fill cans equipped with either standard or BOV valves.

- All materials, including bag and seal, are FDA-approved

- Content utilization up to 99%

- Wide range of actuators: sprays, gels and other viscous products

- Filling lines available in a wide range of speeds

- Traceability of production lots
