These Sealed Air Mail Lite Tuff bags measure 350 x 470mm and are made from high quality, durable polyethylene material, ensuring your products are protected from water and outdoor weather. The bag is lined with protective AirCap bubbles, which create a special air retention barrier to seal each bubble against air loss. This provides cushioning support to your products, ensuring they remain well protected against in transit damage. Plus, because these recycled padded envelopes are made from single material, they are also 100% recyclable after use. Featuring a peel and seal adhesive closure for fast and efficient packing.
