What Are USPS Plastic Shipping Bags?

  • Weather Resistance: Plastic film provides a strong barrier against moisture, dust, and dirt, protecting items in various shipping conditions.
  • Secure Closure: Many USPS-approved mailers feature tamper-evident adhesive seals that enhance product security.
  • Space Saving: Their slim design reduces bulk, maximizing storage and making them easier to transport.

Applications Across Industries
