Electron Beam Technology for Food Packaging, PepsiCo
As consumers, NGOs and governments worldwide continue to seek innovative solutions for the development of a circular economy, PepsiCo is leading the way by working with the flexible-packaging supply chain to develop advanced materials and processes for food packaging.
As part of these PepsiCo initiatives, the company is exploring electron-beam curing, as a fast, clean and energy savings way to dry inks, coatings and adhesives for its flex-pack operations. Todd Fayne, a PepsiCo Project management and execution specialist for packaging materials and processes, has engaged the EB community and RadTech, offering invaluable expertise and knowledge to assist the industry in advancing food-packaging sustainability efforts.

The drive to smaller, faster and more versatile electronic devices such as smartphones has accelerated innovation in state-of-the-art computer chips. With the urgent need to reduce the overall size of the chips while at the same time maintain extremely tight tolerances on the thickness of the new generation chips, breakthroughs in process control are required.
Recently UV-based in-process endpoint technology has made multiple-film, real-time processing possible. The system requires a UV-permeable polymeric film to achieve the required performance. Applied Materials has integrated a high-energy stationary UV-cure system to fabricate the UV-transparent polymer films. Current films have the capability to exhibit extremely high transmittance in UVA and UVB. However, as the thickness of the chips continues to be reduced, there is a need to further extend the transmittance of the film to the UVC region to allow the use of novel materials chemistries and cure systems. The optical uniformity of the film and time to cure makes UV curing a critical technology for these processes. Beyond semiconductor-chip manufacturing, this method of control has applicability in a wide range of industrial-processing systems where precision is critical to the product success and in emerging technologies like Augmented and Mixed Reality.
