In your daily life, you must have bought aerosol spray! But do you really know these tips?

An aerosol can is a complete pressure packaging cans composed of valves, cans, and contents (including products, spray propellants, etc.). When press the valve button, the contents are released at a predetermined pressure in a controlled manner.

Aerosol is a new type of aerosol product produced in the modern fine chemical industry. Its production and filling require the use of professional aerosol filling machines, which have the advantages of small volume, convenient portability, simple use, fine sprayed materials, uniform distribution, and full application effectiveness. There are two types of materials used in aerosol cans: aluminum and sheet metal. The propellant used in aerosol filling machines mainly includes propane, butane, or dimethyl ether, and some pharmaceutical aerosols are temporarily filled with Freon.

The packaging of aerosol is divided into normal packaging and bag-on-valve packaging:

Normal Aerosol Packaging,propellants and materials are mixed in an aerosol can. Propellants are used to pressurize to promote the spraying of materials and assist in the atomization of materials. They are sprayed together with the materials. If propane butane is seen in the composition list of ordinary spray, it is an ordinary aerosol. Propane butane is a flammable gas, so it is not very safe or environmentally friendly.

Bag-on-Valve Packaging: Bag-on-valve packaging is a multiple protective packaging system composed of valves, bags, Aluminum cans, or Aerosol tin cans. The material and propellant are packaged separately in their respective containers, reducing the complexity of the formula and not releasing the propellant during use, thereby reducing the impact on safety and the environment.

Can aerosol spray carry on the plane, subway and high-speed railway?

Compression spray with flammable signs: no consignments, no boarding.

Compressed spray without flammable signs: it can be checked in, and it is forbidden to carry it on the aircraft.

Ordinary spray can: it can be checked&carried on the aircraft (must be less than 100ml)
