The market has witnessed a rapid growth of Bag on Valve (BOV) technology these years, especially in the field of pharmaceutics, personal care, and household care.
Bag on valve technology shows its outstanding advantages in many aspects. It can isolate the product from the propellant gas, thus prolonging the shelf life dramatically. It uses non-flammable gas(Nitrogen or compressed air) as the propellant gas, which is much safer than the traditional aerosol technology. It is also able to eliminate the deterioration of product quality caused by the loss of solvent and decomposition of propellant.
It has been widely used in personal care, household care, food and beverage, pharmaceutics, etc.
The first Bag on valve technology was developed in Japan in the 1990s, and then it got very popular in Asia. It is still expanding rapidly in the European market. As a leader in this field, Nidec-Mitsui developed BOV technology for various industries (pharmaceuticals, cosmetics, etc.) over 10 years. The company based on its own rich experience and latest technologies proposed a wide range of BOV products to satisfy various needs of customers. Nidec-Mitsui’s BOV products are now exported to more than 50 countries/regions around the world with a high reputation among customers for their excellent quality and competitive price.
Pressure-free spray container (PFS) is a new type of spray container which has two parts: the bottle and the cap. The bottle is made of high-quality transparent material, such as polypropylene(PP), polyethylene(PE), polystyrene(PS), or polycarbonate (PC). The cap has a valve for controlling the spray direction. It is pressurized by air or nitrogen, which makes the liquid inside it be sprayed out through the valve. This kind of spray container can be used in all kinds of applications that are normally carried out with aerosol cans, such as household care products, personal care products, food products, etc. Thanks to its pressure-free design and other unique features, it offers many advantages over traditional aerosol cans.
Bag on Valve technology provides an excellent solution to many issues regarding aerosols. It eliminates all problems related to conventional aerosols. See Terco’s superior implementation of Bag on Valve BOV aerosol machines.
Bag On Valve aerosol technology is a new way of packing your products. Are you looking for a packaging solution for your aerosol products? Such as cosmetic and beauty products, food products, pharmaceutical products, fire extinguisher etc. Or you just tired of using traditional aerosol packaging technology? Then why not try to use bag on valve aerosol technology to fix your packing issues?
Conventional aerosol spray technology
Conventional aerosol packaging combines three elements:
- Product to be sprayed: blending active and inactive ingredients.
- Propellant: a gaseous compound mixed with the product to ‘push’ it out as spray or foam. In some cases, the propellant also acts as a solvent to keep the product in desired form. Usually, the propellants is a naturally occurring hydrocarbon, like propane, isobutane, normal butane or ethane, or a hydrofluorocarbon like HFC 134 or HFC 152.
- Canister: steel or aluminum leak-proof can, fitted with push-button spray valve, to keep product/propellant mix contained under pressure,
- Pressing the actuator button opens the valve. Differential pressure between can contents and outside atmosphere allows propellant to expand, pushing the product out through the valve as fine mist or jet spray.
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.
In use, the propellant exerts pressure on the outside of the bag, ‘squeezing’ product through nozzle in a mist or jet spray when the valve is actuated.
There are three key differences between a standard aerosol and BoV spray delivery:
- Product and propellant remain physically separate eliminating the risk of adulteration or contamination
- Less aggressive propellants can be used
- The product undergoes less chilling from the propellant and emerges closer to room temperature.
Why Bag on valve aerosol products spray
- Better Quality Of Finished Aerosol Products.
The finished aerosol product with bag on valve technology has better spray effect, mainly reflected in the wider spray range, the spray molecular weight is more even and finer, and it is easier to be absorbed.
- No Limited Substances.
The gas and the material in the traditional aerosol spray technology must be mixed, so the choice of the substances is limited.
The gas and substances in the bag on valve packaging technology are separated, there would be no limit for the used material.
- Safety Guarantee.
The most commonly used gas in traditional aerosol spray packaging is propane, which is very easy to explosive in high temperature or high pressure environment.
Therefore, the traditional aerosol spray packing can not be taken on the plane. The gas in the bag on valve package is usually nitrogen or compressed air, these kind of gases are safe.
- More Environmentally Friendly.
The gas and material of the bag on valve package are separated. The material is filled into an vacuum bag, but the compressed air is filled between the bag and the cans.
The compressed air squeeze the bag to spray the material, thereby avoiding pollution caused by direct contact.
The whole filling process are finished in the aseptic workshop, and the whole process guarantees aseptic operation.
You may have heard of the term “Bag on valve” aerosol cans and wondered to yourself what the difference is between this and traditional aerosol cans. Well, for starters, Bag on Valve aerosol cans, or BoV as it is commonly referred to, has a much longer shelf life than traditional aerosol cans. You don’t have to be an environmental enthusiast to realize that there are many ways that BOV aerosol cans are superior to their traditional predecessors.
BoV technology instantly separates propellants (nitrogen or compressed air) from the product by using flexible FDA-approved product filled laminated bags. These bags are placed inside of the aluminum or steel can and the propellant fills out the space between the bag and the can. Specialized BoV technology uses the energy of the propellant to push the product out of the bag when the actuator is pressed.
Because of this technology, BoV aerosol cans are effortlessly able to provide consumers with product and makes product emptying a lot easier. In fact, BoV technology can provide up to 99-100% of product emptying! BoV aerosol cans are able to level up traditional cans in this category because BoV aerosol cans are able to separate the product from the propellant and use the propellant to squeeze the product out. Traditional aerosol cans do not have this feature. As a result, traditional cans generally run out of propellant before the entire product is used, meaning there is leftover, unattainable, wasted product!
BoV technology also uses the separation of product and propellant to protect the product from oxygen exposure with air-tight cans, because of this, products have an extended shelf life!
Types of Product
The advanced BoV technology has given various companies the freedom to place virtually any form of product in these cans. From gels to liquids, ointments, and creams BoV has made it possible to dispense many forms of product! Being able to place multiple forms of product in these cans can also increase brand recognition.
Having products placed into BoV aerosol cans makes life easier for the consumer. There are plenty of benefits that come with BoV technology like reduced spray noise, even dispensing at all angles (including the unheard of upside-down angle) and eliminates the need for pumping motion!
Non-Flammable & Environmentally Safe
Having non-flammable products is a great feature and you can bet your bottom dollar that Bov is non-flammable as well! What separates BoV aerosol cans apart from traditional aerosol cans in this category is that with traditional cans the propellants are mixed with the product, whereas BoV’s propellants are separated! The mixture of these two makes them flammable.
The use of, or in this case disposal of, non-flammable products makes getting rid of discarded cans safer and easier.
Another beautiful feature of BoV technologies is that these cans are sterile, hygienic and are generally free of preservatives. Because you don’t have to touch the product or even come in contact with it to dispense it ensures that these products are safe for the customer and pure in dispensing form.
So whether or not you’re a consumer or a manufacturer, BoV’s innovative technology continues to bring aerosol cans forward and have helped to bring overall consumer confidence and satisfaction back to aerosol cans!
LCN Series Dispensing Nozzle
Terco Announces LCN Series Filling Nozzle Development
Terco Inc., the Bloomingdale, IL (USA) manufacturer of aerosol and liquid filling equipment, announces the development of the Large Capacity Nozzles, otherwise known as the LCN Series. The nozzle series is an addition to the company’s current selection of dispensing nozzles.
The LCN Series was developed to handle products that are either foamy or of higher viscosities than can be easily handled by conventional filling nozzles. The units feature a larger dispensing orifice to increase the ratio of liquid cross section to atmosphere contact area, thus reducing the amount of agitation and air entrapment in the product stream. The nozzle is mounted to an articulated mounting that allows for adjustment to facilitate sidewall filling.
These improvements allow for faster filling times to increase line production speeds. Initial field production tests on aerosol glass cleaner products showed over a 40% reduction in the time required to liquid fill the product as compared with traditional filling nozzles.
In addition to being offered as upgrade options on all of the company’s standard products, the nozzles are designed for retrofitting to machines already in field service. This includes the advantage of being able to be fitted onto other manufacturers filling equipment.
According to the company “… the LCN Series nozzles represents our commitment to use the experience we have gained over the past 35 years to further improve the production output of the modern filling operation. Given the present economy and the increasing need for production line efficiencies, the nozzles offer a viable low cost solution to increasing the capacity of any filling operation.”
The LCN Series nozzles are constructed from either 300 Series or 316 Stainless Steel and feature anti-drip design. They also feature Terco’s dynamic seal technology that allows for adjustment of minor seal wear without the need to replace or rebuild the dispensing nozzle.
