Electron Beam Technology for Converting Applications

Electron beam (EB) technology has been used in converting applications for more than

30 years. The use of EB is driven by a number of factors including: product

performance, product consistency, high throughput, energy savings, and the absence of

solvent. The nature of EB technology can also enable unique converting applications that

are not possible by other means.

A new generation of lower cost, more compact EB equipment has been recently

introduced (Figure 1). This equipment operates in the range of about 70 to 125 kV. This

equipment is well suited for curing of inks and coatings used in package printing

applications. A number of articles have been written focusing on these printing

applications. It is perhaps somewhat less well known that this same new generation EB

equipment is also well suited for a variety of non-printing converting applications. For

the purpose of this discussion, converting applications are grouped into seven basic

processes which are described below.
