Automated Aerosol Packaging System for Efficient Production
What is Aerosol Packaging?
A pressurized packaging system, which can dispense the product out of a container and create an instant aerosol (spray).
Aerosols are those particles or droplets, ranging in size from about 0.15 to 5 microns, which are suspended or dispersed in gaseous media such as air, fog, dust, and smoke. Natural aerosols are examples of these.
A unique packaging concept acceptable in many consumer products. In this system, the economic container and value system work. The aerosol pack needs product, and the propellant is under higher pressure; the opening of the container is fitted with a special mechanism known as an aerosol valve. The valve is fitted with a plastic tube that reaches to the bottom of the container.
Aerosol Packaging Used For
As long as the product is non-corrosive and the particle size is lower than 50 microns, it can be packed in an aerosol.
- Personal care– perfumes, antiperspirant, Hair setting mousse
- Household- furniture polish, disinfectant spray, glass cleaner, oven cleaner, carpet cleaner, room freshener.
- Pharmaceutical-Inhalers, inhalation therapy for asthma is totally packed in aerosol. First-aid spray, pain-reliever spray, cooling spray.
- Industrial- lubricant, silicon spray, Electronic cleaning spray, spray paints, carburetor cleaner, car starting fluid spray, tyre inflator, and sealing.
Types of Aerosol (Containers)
- Three-piece tin-plated steel cans with one inch value opening. They are available in sizes from 50ml to over 1000ml
- aluminum move block cans are extruded from an aluminum lug. After outside printing, the top part is rolled into a narrow dome and value opening forms (Necking Procedure). These cans are available in a wider range, from 10ml to over 1000ml
- Glass bottles as aerosol containers offer a wide variety of designs and good transparency.
- Steel (Stainless) can be used in special cases of pharmaceutical applications.
- Plastic containers are used but not very popular (acceptable).
Benefits of Aerosol Packaging
Convenient of use- just by pressing the actuator, one can get the desired product in the form of a five-spray, streamlined jet, foam, or cream.
- No wastage of products / avoid the mess
- Controlled rate and quantity of product.
- Unique use– The effect of five sprays of perfume or a thin layer of hair spray cannot be achieved by any other means of packaging.
- Quick-drying spray paint and metered dose of inhalation medicine are only possible in aerosol form
- The aerosol package is hermetically sealed (higher pressure than the atmosphere), and there is no chance of anything entering it
- No contamination &adulteration is possible
- Easy to open and close.
Types of Aerosol System
- Solution system
- Water-Based System
- Suspension of dispersion system
- Intranasal aerosolsÂ
Foam System
1. Aqueous stable foams
2. Non-aqueous stable foams
3. Quick breaking foams
4. Thermal foams
Limitations of Aerosol Packaging
- Aerosols are costly preparations
- some of the propellants are very toxic.
- The cooling effect of highly volatile propellants may cause discomfort on injured skin.
- A lot of difficulties are faced in aerosol formulation when the drug is not soluble in the propellant.
