I live in the south and it's humid. These bags work perfectly. They hold a 1kg roll and I easily fit two 500lb rolls in one bag. I've opened and sealed them a dozen times and had no problems. Just remember to slide the roller into the corner of the bag opposite the valve and then place the pump on the valve on a flat surface and you're done!
