I’ve done fruit by the foot and fruit roll ups. I personally prefer fruit roll ups. I think the fruit by the foot turns out too hard due to its thickness. Shame because it’s so much easier to handle!

I too use mylar for the more durable candies and tubs for the fragile items. I have found that using the shrink wrap bands do little to make containers any more air tight. However, I have used stretch wrap (think thin Saran Wrap) around the lid and have been surprised how long some delicate items have stayed crisp. I also used a boba type cup sealing machine and have keep products fresh for weeks. Just know that I haven’t done any formal testing/documenting of results. FYI-I live in a high humidity climate. In regards to bags…test your bags. I’ve filled some with air, zipped them shut and heat sealed them. I then place them underwater to find that there is a leak either at or below the zipper! Just another reason not to bag until close to sale date!
