Are your bags freezer-safe?
We have a line of Liquid/Freezer Stand-Up Pouches in stock. You can check the out here: https://www.clearbags.com/bags/barrier/pouch/liquid-freezer-stand-up-pouches
We do have customers that use other bags for frozen products like popsicles. That being said, we encourage customers to request samples of bags that work with their products. Test the bag with the product in the freezer and see what the results are.
Typically, for long-term freezer storage, you want to find a bag with nylon added into the material. This will allow the bag to expand and contract to different temperatures and the items inside of the bag. While we don't sell nylon additive bag stock, we do custom nylon additive bags all the time. Contact a customer packaging expert for more details.
Additionally, we have a blog post that should be able to help inform your freezer bag decision: PICKING THE BEST FREEZER BAG: 4 TIPS TO PREVENT FREEZER BURNED PRODUCTS
