Cooler Shock vs. Regular Water
Ice starts out at freezer temperature and will warm fairly quickly to its melting point (32 degrees F). Once at melting point, the ice will stay at the same temperature during the whole process of melting. After fully melting, the liquid starts to warm normally again.
Cooler Shock ice packs also start out at freezer temperature, and will warm pretty quickly, but it’s melting point is at a much lower temperature — 18 degrees F. During the whole process of melting, Cooler Shock stays at this lower temperature. This lower melting point means that when ice begins melting and warming in your cooler, Cooler Shock packs still stay cold, even as they begin to thaw.
Frequently Asked Questions (FAQ)
- Do I need to refill the packs? No, you do not need to refill your Cooler Shock packs. Once they are sealed, they should not be opened or emptied.
- Can I use my Cooler Shock packs in the refrigerator? Cooler Shock packs are expertly designed to provide the best cooling energy when frozen. We do not recommend using Cooler Shock packs in the refrigerator because your fridge does not usually get below 32 degrees F (a.k.a. freezing temperature).
- What is the difference between the zipper packs and the screw cap packs? Essentially, nothing. The packs contain the same ingredients. The only difference is how you fill and seal the packs at home. The zipper packs require an iron to seal, whereas the screw cap packs use a funnel and cork (provided) to create a leak-proof seal.
- How long should Cooler Shock packs be frozen before use? We recommend 48 hours for large packs, 24 hours for mid-size packs, and 12 hours for lunch-size packs for best results.

DIY Reusable Bags — Just Add Water Once
Cooler Shock ice packs are shipped dry with a proprietary cooling gel mixture inside that turns into a solid block when frozen. Just add water at home, shake, and seal to create reusable ice packs that can be used over and over.
Choose from two closure types:
- Screw cap with cork and included funnel for filling.
- Zipper version that’s sealed permanently shut with an iron.
Thin, Durable Construction
Cooler Shock’s flexible, multi-layer bags are made with aluminum and polyethylene to keep the contents secure and reinforced with thin nylon to help strengthen the pack.
Measuring about one-fifth the thickness of rigid ice packs, Cooler Shock’s thin walls (8 mils, or about 0.2 mm) freeze quickly without losing cold-transferring effectiveness.
