Bag-on-valve sprays are modern and eco-friendly alternatives to conservative spray cans. Although these aerosol packing technologies share similar objectives, they differ in functionality and safety. BOV has a longer shelf life and contains no toxic elements capable of causing adverse environmental contamination. Conventional canisters have volatile organic compounds (VOCs) as the main components, such as non-decomposable metallic substances and petroleum products. Contemporary aerosols use space-age technologies to keep the chlorofluorocarbon-free compounds under control. They offer better spray packaging solutions with minimal environmental impact. Keep reading to know how the packaging solutions vary and why environmentally friendly aerosol cans are safer alternatives.

Aerosols History and Evolvement

The aerosol concept initially emerged in the 1790s in France as a carbonated drink self-pressurization contrivance. In 1837, Perpigna reinvented the concept by introducing a valve-based soda siphon. About 30 years later, the first heavy-steel metallic canisters were invented. In 1899, Pertsch and Helbling, famous inventors of their time, patented ethyl and methyl chloride-propelled aerosols. However, the current selection of environmentally friendly aerosol cans didn’t exist until the mid-20th century. William Sullivan and Lyle Goodhue developed the original model of the present-day environmentally friendly aerosol cans. It was a miniature-sized canister propelled by liquefied gas, which they released in 1943, and was mainly utilized by armed forces during the Second World War II. Although soldiers used bug repellent spray during the Second World War, they weren’t available to civilians until 1947. But the old-style aerosols didn’t last long as many American aerosol manufacturers substituted the harmful CFC propellants with eco-friendly alternatives in the 1970s. This happened after Dr. Mario Molina and Dr. F. Sherwood Rowland raised the alarm about the environmental impact of CFCs. In response to Rowland and Molina’s findings, the U.S. EPA debarred CFC propellants’ production and use. Over the last few years, many advanced and eco-friendly alternatives to traditional vaporizers have been introduced. One of the most eco-friendly and cost-effective technologies used by many aerosol packaging companies is the bag-on-valve technology. In 1953, Robert H.Ablanalp filed the first-ever aerosol-related crimp-on valve patent and the beginning of the Precision Valve Corporation, which mass-produced aerosol valves. 1982 saw the filing of the first-ever BOV design patent in Europe, which involved using sodium bicarbonate and citric acid as propellants. In 1985, NASA created a Pepsi drink packaged in BOV environmentally friendly aerosol cans.

Adverse Environmental Effect of Conventional Aerosols

Traditional atomizer cans have many shortcomings that make them unsuitable for modern-day applications. The science-backed negative effects surrounding the cans spearheaded environmental health campaigns against their use. The harmful effects of these spray canisters include:

Depletes the Ozone Layer

VOCs emitted by conventional spray canisters have a damaging influence on the stratosphere. The VOC reacts negatively with nitrogen oxides forming ground-level ozone. Molecules emitted by the ground-level ozone hazardously react with ultraviolet rays to proliferate the ground-level ozone layers. This intensifies problems related to this stratosphere stratum, mainly during hot days. CFCs in spray canisters are stable composites that don’t dissolve in water. When discharged into the atmosphere, they stick around for hundreds of years. Although the ozone undergoes self-destruction and renewal, CFCs upset the balance, making the destruction rates higher than the recreation rates. Similarly, the spray canisters intensify levels of smog and air pollution. These canisters comprise VOCs, which reduce atmospheric visibility.

Emits Hazardous Gases

Aerosols emit dust and fumes that are suspended in the air. These particles can be absorbed by your skin or inhaled. Inhaled for extended periods, the gases can have serious health effects. They can pollute your space, making it hazardous while worsening asthmatic conditions. Harmful gases generated during aerosols’ packing often cause long-standing infirmities and even death. Exposing age-sensitive people, specially babies and adults to these harmful environmental conditions increases the mortality rates. For this reason, aerosol packaging companies no longer use conventional canisters as they threaten their employees’ well-being.

Causes Radiation Problems

Aerosols directly or indirectly interact with the planet’s radiation climate and budget. In direct interactions, they disseminate sunlight directly into space. In indirect situations, those placed low in the atmosphere modify the cloud particles affecting sunlight absorption and reflection of the natural cloud. That negatively affects the earth’s energy budget. These harmful elements also offer stable conditions for chemical reactions to occur. The most popular of the reactions are the ones that destroy the stratospheric ozone. During winter in the Polar Regions, aerosols propagate to create polar stratospheric clouds. They act as sites for chemical reactions that trigger huge amounts of reactive chlorine and ozone layer destruction.

Problematic and Hazardous to Dispose of

Disposing of aerosols is a hazardous and tricky process, whether in liquid or pressurized liquid form. Disposing of the canisters with some particles of the harmful substance can have a detrimental effect on the environment and people. The perfect way to dispose of the cans is by donating or selling them to scrap metal collectors to recycle them properly. As everyone is concerned about ecological conservation, aerosol packaging companies have welcomed the ingenuity of alleviating the impacts of these compounds on the atmosphere through recycling the canisters. Aerosols are chemically impulsive compounds. If not properly disposed of, they could trigger fires, polluting the surrounding air and soil.

What are Bag-On-Valve Cans and How Does It Really Work?

The bag-on-the-valve (BOV) is a 4-layer-film canister welded to an aerosol stopcock. It’s a packaging technology commonly utilized by aerosol packaging companies to package liquid and vicious products. The four-layer technology splits up the stored product from the biodegradable propellant. This preserves the product purity while offering 100% recyclability, a feature not available in conventional cans. The BOV environmentally friendly aerosol cans are mostly made of metals. They have an inch opening when the valve crimps. The valve crimp is soldered to a foil vessel with a laminated film with multiple layers. After the valve is crimpled, aerosol packaging companies add compressed air/nitrogen into the space between the systems bag and canister. This occurs in a process known as under-the-cup gassing. It’s a multi-secure system featuring things such as aluminum-made cans, vacuum bags, and aerosol valves. The bottles are the outer part the BOV packaging, which are divided into three options based on whether they are created of PET, tinplate, or aluminum materials. The dual-chamber packaging technology has become a favorite for aerosol packaging companies operating in different industries. Key players in the cosmetic industry use these environmentally friendly aerosol cans to safely package things such as self-tanners, creams, and more. You’ll realize that most contemporary body and skin care products have the BOV packaging. In addition, the food industry largely depends on BOV containers to package everyday items, including cooking oils, vinegar, and salad dressings.

Benefits of Bag on Valve Cans

The benefits of bag-on-valve technology are divided into three segments: end-user, manufacturing & sales, and environmental health and safety.

Benefits to the End User

When aerosol packaging companies use environmentally friendly aerosol cans, one of the principal beneficiaries is the end-user. These containers offer a 99.9% empty rate, so the end user consumes most of the content inside the bag. Therefore, you’ll use everything you paid for, getting maximum value for your money. The bags have a 360-degree spray capacity, meaning you can spray them from any angle, including upside down, which reduces product misappropriation. Another benefit of environmentally friendly aerosol cans is their ease of control and versatility. As the end user, you’re allowed maximum controllability. The canisters are efficiently designed to offer smooth and even dispensation of the content inside, giving you clear-cut control over the product administration. The advanced technology eliminates the noise made by traditional canisters while the propellant is escaping. Additionally, these canisters offer smooth and continual dispensation of the product. You don’t have to constantly press the actuator to dispense your product. Most importantly, the cans don’t have the chilling gas discharge familiar with conventional aerosols.

Environmental and Safety Benefits

Using environmentally friendly aerosol cans by aerosol packaging companies also benefits the atmosphere. Aerosol packaging companies mostly use non-VOC pure N2 or air as a propellant, which is friendly to the atmosphere. The packaging comprises vacuumed food-grade bag, requiring fewer preservatives, which makes it healthier for consumers. Aerosol packaging companies use non-flammable gas, so there are no threats of explosion problems like in the case of hydrocarbons. The 4-layer environmentally friendly aerosol cans have a laminated pouch offering an impermeable and superior barrier. This barrier is not affected by ambient temperature. The compacted propellant used in the packaging is inert, so its pressure is stable and won’t change with a temperature change.

Sale and Manufacturing Benefits

Aerosol packaging companies enjoy more manufacturing and sale benefits when they use environmentally friendly aerosol cans. They offer longer shelf-life for all oxygen-sensitive products, thanks to the isolating bag that keeps them safe from compressed air. Despite its ability to prolong the life of products, bag on the valve packaging technology is cheaper for the sellers. BOV technology is compatible with all product types, including viscous and liquid products. It means more possible application areas and business opportunities for aerosol packaging companies. The eco-friendly aerosol packaging solutions have standard aerosol cans and actuators, so they don’t need additional tooling for cans and actuators. Aerosol packaging companies and product sellers also save on infrastructure costs.
