Review of Hercules Sustain Freezer Bags Twin Zip Medium

I have been buying Hercules freezer and sandwich bags for a long time due to their lower price and ability to do the same job as more expensive brands. I recently started buying these Hercules Sustain Freezer Bags, which are made of 25 per cent plant based plastic. They seal well and have a panel to write the details on. They also prevent freezer burn.
