PFE tested a bag made with two layers of film and a polyethylene closure. The outer layer, made of Scholle IPN’s RecShield®, is a barrier film specifically designed to keep unwanted flavors from migrating through the film into the water. The inner layer consists of Scholle IPN’s proprietary film technology, known as 2Pure™, which contains scavenging technology that protects the taste of the packaged water.
