An aerosol is a suspension of fine solid particles or liquid droplets in a gas. The criteria for packaging of aerosols involves speed, simplicity, spray projection, cleanliness, freshness. Aerosol comes in metal containers (tin, aluminum) but now a days metal containers are replaced with plastic containers as it provides advantages like light weight (lower storage and transport costs, improved ergonomics and user friendliness), increased safety (no highly flammable propellants, no poisonous gases that might be inhaled) , environmentally friendly ( no propellants and no volatile organic hydrocarbons, less household chemical waste and possible reuse, transparency , no rust ,compatible with current filling lines, it can be decorated by new ways like shrink labels etc. It provides benefits for consumers in having different designs, texture and touch appeal. It provides secondary advantages which are not decisive at the time of purchase) like shelf-life, accuracy of the dose delivered, ease of use while carrying. These attributes give the plastic aerosol market a radiant future, particularly in the case of non-flammable, low-pressure products. PET is used as a major raw material as it is good barrier, cheap, pressure-resistant material, it has less energy-intensive production and it has new artwork possibilities like sleeving , labelling etc. Plastic aerosol cans fulfils the same requirements and have the same maximum brimful volume as metal cans (1000 ml) and can be filled the same way as metal cans (maximum pressures of 13.5 bar at 55°C, adapted in US 160 psig at 130°F and Canada 1105 kPa=11.03 bar at 55°C).

Dolcera report focuses on finding the key innovators and the industry ecosystem through relevant patents, clinical trials and university data encompassing the plastic container for holding aerosol content under pressure. Mostly includes a one-piece integrally molded plastic body having a base, a sidewall and a neck finish. A pressure container having an extruded plastic body portion is described mostly in relevant patents. The keywords used in the search were obtained after an extensive study of relevant patents. The class codes for the search were obtained from the control patents and more class codes with manual search of classification index. The report highlights year-wise patent activity (trend line) along with the key industrial players in the field. Patents are categorized on the basis of patent focus- aerosol container whose body is made up of plastic material (example PET, PEN etc.). The categorized patents were further analyzed to determine the key players under each category. A comprehensible result in the form of Dolcera dashboard has been given. Dashboard links the companies in each category to their patents, hence making an interactive platform for analysis. Furthermore, patents have been mapped to commercially available products produced by the respective assignees and other licensees.


Aerosol is used by a wide range of industries: health, cosmetics, food, automobile and household chemicals. Plastic aerosol containers provide numerous benefits for consumers: lightweight, lower storage and transportation costs, design, texture, transparency, user friendliness and possible reuse. They are suitable for non-flammable, low pressure products. Plastic aerosol provides significant environmental benefits to metal packaging as there is no volatile organic carbon. The Keltec dispensing systems convert a liquid into foam by using pressurized air instead of a propellant. The new shapes and the artwork possibilities make them very attractive for the packaging of new products. The European aerosol federation (FEA) has developed new requirements for plastic aerosols. There are tests for the empty container and filled aerosol. Graham packaging has developed a PEN aerosol for a body hygiene product in 2002 and have recently developed a PET product because PET is cheap and is a pressure resistant material. The main advantage of a plastic aerosol are no rust, no BPA (bisphenol-A), easier working, compatibility with current filling lines, and new ways of decorating the product such as shrink labels.
