ABSTRACT
In this review paper we are going to study about future of aerosol packaging and also focus on definition, Manufacturing, working principal, advantage, disadvantage, current market and its future. Aerosols cans used in mostly all packaging industries, pharmaceuticals, cosmetics, chemicals, food etc. The global aerosol market size was 15.48 billion units in 2015 and is expected to witness substantial growth over the next eight years on account of its growing usage in household and food sector.
Keywords: liquefied gas propellant, pressurized packages
I Introduction
Aerosol spray is a type of dispensing system which creates an aerosol mist of liquid particles. This is used with a can or bottle that contains a payload and propellant imder pressure. When the container's valve is opened, the payload is forced out of a small hole and emerges as an aerosol or mist. As propellant expands to drive out the payload, only some propellant evaporates inside the can to maintain a constant pressure. Outside the can, the droplets of propellant evaporate rapidly, leaving the payload suspended as very fine particles or droplets. Typical payload liquids dispensed in this way are insecticides, deodorants and paints. The concepts of aerosol probably go as far back as 1790. An Aerosol also called as Pressurized Packages, Pressure Package or Pressurized dosage forms. The term pressurized package is generally used when referring to the aerosol container or completed product. Pressure is developed to the aerosol system through the use of one or more liquefied or gaseous propellants. The first aerosol cans were heavy steel "bombs," consisting of two shells about 0.090 in. (2.3mm) thick, brazed together at the lateral centerline. They were known at least since the early work of Eric A. Rotheim (Oslo, Norway, 1931) and gained fame during 1943-1945 as insecticides forU.S, troops fighting in such places as Guadalcanal and other South Pacific areas. After the war, these products were made available to the public, but acceptance was very poor, due to the high initial expense and the aspect of having to return the emptied unit for refilling. It was obvious that a lightweight, disposable can was needed. In 1946-1947, Harry E. Peterson developed sucha can in the laboratories of the Continental Can Corporation in Chicago. It consisted of a 2.68-in.-diameter...
