Company invents fire-suppressant, paper-packaging wrap for lithium-ion batteries

PACT Thermo Shield is a lightweight, pleated paper material treated with a non-toxic moisture vapor application.

Packaging and Crating Technologies (PACT) in Connecticut (U.S.) has created what it says is the world’s first fire-suppressant paper packaging wrap, designed specifically to control dangerous lithium battery thermal runaways.

“Lithium-ion batteries are in almost every electronic device we own,” said Rodger Mort, President of PACT LLC. “They can become dangerous if damaged or defective, potentially causing devastating fires. Our PACT Thermo Shield is a protective and affordable solution quickly becoming essential when traveling, shipping, storing or disposing of products containing lithium-ion batteries.”

PACT Thermo Shield is a lightweight, pleated paper material treated with a non-toxic moisture vapor application. This treatment prevents thermal runaway, an uncontrollable self-heating state triggered by high temperatures, vibration or puncturing during transit. This phenomenon can lead to the ejection of toxic gas, shrapnel, smoke and fire.

When thermal runaway occurs, PACT Thermo Shield cools the package’s internal environment while reducing the oxygen supply, preventing the event from spreading and suppressing a potential fire. The wrap can withstand temperatures up to 800 degrees Celsius (nearly 1,500 degrees Fahrenheit) while maintaining the outside temperature at 60 degrees Celsius (140 degrees Fahrenheit), the company says.

“Lithium-ion battery fires are hard to extinguish and often smolder for hours, emitting lethal fumes and gases,” Mort says. “Our product’s ability to contain both the fire and residual smoke within the protective wrap is vital.”
