Tetra Pak: Electron beam package sterilization

Tetra Pak has launched a filling machine that uses electron beams, not hydrogen peroxide, to sterilize packaging material; the E3 delivers a range of benefits to customers, including the potential to run up to 40,000 portion packages/hr.

Compared with the existing Tetra Pak A3/Speed platform, Tetra Pak E3 machines will also provide lower operational costs, improve environmental performance and increase production flexibility.

eBeam sterilization technology works by focusing a controlled beam of electrons onto the surface of packaging material as it runs through the filling machine, killing any bacteria or micro-organisms present. The use of eBeam removes a long-time physical limitation to carton packaging speed: the hydrogen peroxide sterilization process. With eBeam, speeds of up to 11 packs per second can be achieved, and market tests have shown this increased capacity can save beverage manufacturers as much as 20% in operational costs.
