ALOKSAK bags have been certified waterproof in excess of 60 meters (approx. 200 feet) for over two weeks by the SSI (formerly NASDA), and passed the submergence/thrash/pull test conducted by the US Navy Experimental Diving Unit. These leak proof products offer unparalleled water-tightness in a recloseable cost-effective bag.
The 6 mil. film of the bag is on par with PVC of the same thickness in terms of durability, but has a lower cold-crack tolerance (minus 60 F.) than that of PVC / Vinyl (0 degrees F.) ALOKSAK is protected by four patents covering the materials, the closure, and the manufacture of the finished product.
ALOKSAK bags are the perfect solution to the most common and important problems associated with storage, transport, and safekeeping. Most electronics can be used while protected in the ALOKSAK. Digital cameras can be used under water in an ALOKSAK as well. While the bag is the best dry bag of its kind in the world, it also offers air tight protection for metals, food storage and electronic equipment above sea level. Due to its waterproof, dust proof, and humidity proof hermetic seal, it is rated as a biohazard hermetically sealed bag.
The bags make great ice packs and also protect food from melting ice while in a cooler. They can be also be blown up to make a nice pillow or seat cushion. Opened food will not go stale because it is not exposed to humidity. The possible uses are almost endless.
See specific size for the number of bags per package. The multipack contains one (1) each of the 4.5x7, 6.75x6, 9x9, and 12x12.
