Lightweight Poly Bubble Mailers
Poly Bubble Mailers are plastic (also known as poly) envelopes lined with air-filled plastic bubbles that provide cushioning. They can mail accessories, books, bulky items and even some fragile objects in bubble envelopes. The cushioning provides some protection for the item being mailed, particularly from bumps and scratches. Bubble envelopes are a great alternative to paper padded envelopes, as they are more lightweight and thus you can save on your postage, and also don't leave messy padding residue when they are opened. Using bubble envelopes is a convenient and inexpensive way to send items through the mail. It is fine to do bubble-envelope mailings for air mail and overseas mail. Most importantly Poly Bubble Mailers can waterproof your contents.
