For explosive materials, it is difficult to fill and being packed. Because explosive materials are sensitive to heat. If the welding method gives more heat to the package, it can burn or explode. Because of this reason, explosive and some chemical raw materials are being packaged by ultrasonic welding machines as cold sealing method. When the chemical are so sensitive to heat, the same process is still valid. Because heat can activate the chemical during hot welding so it is important to use cold welding and because of speed and easy to use, ultrasonic welding is preferred in explosive industry.
