This is from a description of pesticide use and the harm that it can cause honey bees. They are doing different tests:

"Per le prove sono state utilizzate delle gabbiette sperimentali munite di un **foglio cereo** e di un alimentatore a siringa".

Any ideas if there is a specific term for this foglio? Is it simply wax sheet?

Thanks, I appreciate your input.
