Topside Embossing
Topside embossing is similar to backside embossing and has many of the same inherent
advantages and potential applications. In the case of topside embossing the pattern is
defined by a “parent” film. The parent film may be a roll or a continuous loop. It should
be designed to resist damage from EB exposure and also cleanly release the coating upon
curing. The pattern on the parent film is accurately reproduced on the new substrate upon
curing.
Conclusions
EB technology may be used in wide variety converting applications. EB provides
environmental and energy saving advantages compared to thermal curing processes. The
nature of EB technology can enable unique converting processes. The development of
smaller, lower cost equipment makes EB an attractive technology for expanded use in
converting applications.
