"Mylar" Bags - MVP Marvelseal Long Term Storage Pouch - Faraday Bag
These pouches are made of exact specifications to meet very low moisture vapor transmission requirements. Our bags meet the MIL-PRF-131K specification, class 1. Each bag has 3 layers of protection. One layer is Film (Polyethylene for sealing) and one is aluminum. The third layer is a film. They work great inside of a time capsule to protect contents both inside and outside of the bag. For instance, some customers may wish to place an item whose inherent longevity is unknown (a Twinkie, a leather item, a rubber ball, a bottle of wine). Best way to handle this is to pack it inside of an MVP pouch (seal according to instructions - you can use a common household iron as specified).
Each order comes with at least one set of instructions, a sample piece of the MVP material to test on your heat sealing device, and seal release paper (to place in between your iron and the material to keep the material from sticking on your iron). Per Pouch or Roll of Sleeving.
Material used for making the bags: Laminated Film/Foil/Poly. Some vendors call these metallized poly bags. These are a thicker version and are safe for food as well as artifacts. They provide superior protection for items in long term storage, and can be used for EMP bags. Some of the bags have quality control printing on the outside. Bags were made in the USA. All of our bags are safe for food or artifacts. New - we now offer a roll of sleeving - open on two ends - sold in 10 feet lengths (see below).
