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
It’s to keep them from drying out.
Raisins are also sold in other types of packing without that bag and don’t dry out… Like the cardboard cylinder shape canister things
Dehydrated grapes drying out is a concern?
There’s a range of ideal moisture content. Same with weed.
There you go, “sealed well between uses” lol, those dumb bags are not conducive to proper resealing at all
