Great question! Our goal when choosing our packaging materials is to always maximize the convergence of being environmentally friendly, having an efficient combination of materials, and cost effectiveness.
Our gel packs can be reused (you can even store them defrosted in your pantry and freeze when you need to use them!) or donated to local YMCA's, food banks, churches, etc.
The gel is a mixture of 2% sodium polyacrylate (salt) and water. To recycle, cut open the pack and dump the gel into the trash. Rinse the plastic and sort with other #4 recyclables according to your local and state guidelines.
Our liners are made of natural fiber liner pads and poly film on the outside.
