Bag on valve (BoV) is a popular and proven packaging technology with advantages that have defined the benchmark in the cosmetics industry, mainly for shaving foams and creams. But the food industry has begun to rely on the same system as well. It is environmentally friendly and requires no propellant gases.
The BoV system combines a hygienically pure aluminium pouch with an in-welded valve inside a pressurized spray can. The barrier properties of the three- and four-play POLIALUVEL® laminates protect the product against the ingress of light, oxygen, and water vapour. They fulfil the strictest hygiene requirements and assure high safety standards as regards the protection of the chemical and aggressive products. The laminates are suitable for low- and high-viscosity products. Standard spray heads and spray cans can be used.
The BoV system offers the consumer many advantages. The pouch content is dispensed almost entirely, no pumping action is needed, and the product can be sprayed in any orientation. Wipf AG has already successfully implemented projects in Europe and the USA.
