How long will a Henry & Henry Filling bag (rasp. & strawberry) last after I've opened it? How should I store it?

I think you can reseal and freeze the left over sleve fillings.. but someone with more experience may know better than i..

I've actually been wondering this myself. I thought I had read somewhere on here that you can keep them up to six months in the fridge after opened but I'm not 100% sure about that....anyone else?
