Unique protective bubble mailers are made from a durable, moisture resistant, tear and puncture resistant, multilayer blend of co-extruded polyethylene film. Exterior film is laminated to a resilient interior bubble material for effective cushioning, with a bottom fold and strong side heat seals for superior bursting strength. Pressure-sensitive self-seal adhesive closure is reliable, tamper-evident and easy to use. Each bubble mailer weighs less than one ounce to save on shipping costs. Ideal for mailing CDs, DVDs, books, jewelry, pharmaceuticals and more.
