Buy some clear liquid gorilla glue in a metal tube.. get some sand paper 200-400 grit and scuff 1/2 inch around the outside of the hole. Insert a piece of wax paper in the bag where the hole is.. fill the hole and smear the gorilla glue flat and overlap the hole by 1/2 and inch. Let it sit 24 hours.. peel the wax paper off and bag should be good to go. Should have a bag that is usable again.
