The one problem I keep running into is any food with sharp edges poking through my food sealer bags. It causes the bag to leak and loose it’s seal. The following cause the most problems.
So, My solution is quite simple. I take a used fast food bag or even an index card or sheet of paper and line the bag. Be sure to put the date and item contents on the index card facing out! I usually include my own best by date or expiration date. Sometimes it is best to use a paper towel at the top of the bag if I am sealing raw meat to help suck up any liquids during the vacuum process. If the food is going to be stored for a long time then go ahead and take the time to double seal both ends for extra protection.
