Damn, it’s like they don’t want you to get at the raisins. There must be a better way… You either mutilate the bag and your fingers, or cut it with scissors (or a knife - not recommended lol) , either way can’t be resealed without additional apparatus
Idk I do not trust any nowadays, bugs can get inside even the thick ones by making holes, like the pantry moths and start infesting…
Everything goes to thick solid plastic or glass containers as long as I have available. An infestation it still possible but much more difficult plus they get stuck on the recipient they infested and not infesting everything by the time you notice.
