WHAT’S A DRY GEL ICE PACK?https://www.alibaba.com/product-detail/Factory-ODM-OEM-best-ice-packs_1601380249348.html?spm=a2747.product_manager.0.0.513c71d26B9Ifm The key ingredient of the World-bio dry gel ice pack is Sodium Polyacrylate which is an amazing water absorber. It can absorb 200 to 300 times its own weight in tap water (even more if the water is distilled) and stores it in a gel form. The benefit of this is that the gel does not release any fluid so you can create an ice substitute which doesn't thaw like normal block ice does.
