18 x 48 Long Poly Mailer 25/Case

These mailing envelopes are made from 4 Mil polyethylene. They have a self-sealing closure on one end, which makes them super easy to use. They're water-resistant, so your items stay dry. They're also lightweight and puncture-resistant, providing great protection for your mailed goods.

Using these poly mailers is a breeze. Just open the self - seal closure at one end, put your item inside, and then seal it up. Make sure your item isn't too big to fit properly to avoid any tears. When handling, be careful not to scratch the surface with sharp objects as it may reduce the puncture - resistance. You don't need to do any special maintenance for these mailers. Just store them in a dry place away from direct sunlight. They'll stay in good condition for a long time and be ready for your next mailing needs.
