Unfortunately, most are NOT RECYCLABLE. These bags are typically layers of different materials and once those layers are together, it's hard to get components separated so that they can be recycled. Still not sure? Do the 'tear test'....if you can easily tear the bag and don't see a plastic film layer mixed with the paper, it's good to go for recycling. This holds true for some paper plates and gift wrap too.
