Premium Eco Clear Bags are an eco friendly alternative to a traditional poly bag. They are made from 1.6 mil PLA material and are certified compostable. These bags are clear and ideal for packaging items like photos, notecards, recipe cards, and more. GC4X6 measures 4 1/4" x 6 1/8" and has a resealable adhesive strip on the flap of the bag. This allows the bag to be folded over for a tight fit. Food safe.
