AirJacket® Poly Bubble Mailers combine the tear, weather and puncture resistance of a courier envelope with the cushioning of a Durabubble lined mailer. Each mailer is made from 100% Polyethylene and is completely recyclable. The white outer surface is smooth for handwriting, labeling, or custom printing, and the self-seal closure makes packing quick and efficient for ecommerce, retail, office, and fulfillment shipments.
