Poly zip envelopes are made from durable polyethylene or polypropylene film with a resealable zipper-style closure — like a heavy-duty ziplock bag engineered for professional document use. The zipper opens and closes multiple times, protecting contents from moisture, tearing, and rough handling. Unlike paper envelopes, poly zip envelopes are water-resistant, tear-resistant, and often semi-transparent for easy content identification. See how the zipper closure works in the guide below.
