Is there some kind of “law” in choosing ply widths regarding to tubes and if so, would the tubes have the best properties possible?
Ply width usually depends on what characteristics are needed in a core. If beam strength, also called bow strength, is what is desired the wider the ply the better. If a flat crush is desired narrower widths are usually desired. It should also be noted that excellent adhesion is needed to get the desired results and paper grades will play a large part in core strength.
