Eco Clear Protective Closure Bags are the perfect sustainable packaging solution for crafts, cards, art prints, stickers, cosmetics, food, and more. Measuring 4" x 7 1/2", GC4E7HPC is made from plant-based PLA (Polylactic Acid) material that is food safe and high clarity. Each bag comes with a reusable adhesive strip located on the body of the bag. This design ensures that the adhesive does not come in contact with your product while keeping it visible and protected. Going green can happen one bag at a time!
