Filmguard Bags are designed to protect film from exposure to harmful x-rays during airport security and custom checks. These lead lined bags protect unprocessed film and other sensitive media against the low dosage x-ray machines that are used in airports around the world. Without this type of protection, unprocessed film can become fogged or streaked, resulting in lost photographs. The triple layer construction includes and outer shell of water resistant ballistic nylon, a lead-impregnated vinyl sheet and smooth interior nylon lining. Full length 1-1/2" hook and loop closures and water resistant materials keep dust and moisture out.
