This pack of OPSAK Waterproof Bags from Loksak contains two 12 x 20" odor proof, waterproof, airtight bags to protect your electronics, documents, or other items that need shelter from the elements. With resistance to high temperatures, these bags may be used to rehydrate or cook food with boiling water – however, the bag cannot be used as a boil-in bag or sous vide bag. A double-zipper closure creates a hermetic seal, which prevents any air, dust, or micro-organisms from leaving or entering the bag once it is sealed.
The recyclable and reusable OPSAK bags are made from FDA- and NSA-approved medical grade polyethylene that is safe for both food and biohazard storage. You can make and receive calls, and use touchscreens from phones or tablets within the bag. They are certified waterproof up to 200', and remain effective from -40° to 170°F.
