Seal freezer bag 100% waterproof
If you want liquids, e.g. Soups in freezer bags Freeze, you get the bag with the usual clips not completely waterproof and in the freezer can leak something. This can not happen with this trick:
Cut the thread with the lid from a plastic bottle. You can still give the bottle, because the banderole is not damaged.
Then pull the bag through the thread, "fold" the bag and screw the lid over the bag. It can be a bit tricky in the beginning, but it certainly works. So the bag is 100% waterproof.
