From a recent CE/CR meeting:
Meme's question on folding bags in package level 3 could be a problem?
We don't do folded in half. We do tri-fold. Folded for rolls only. We do this so you can take out 1 at a time. Answer: The folding checkbox will only be clickable for for rolls with certain dimensions. Although this option will only be activated for a narrow set of products, having it visible (albeit grayed out) all the time could be a problem; it might encourage customers to ask for this.
