Cut Postage While Protecting Your Documents

Lightweight and sturdy. Elegant yet virtually indestructible. Tyvek® envelopes hold up in even the most rigorous of mailing conditions, keeping the elements out and your important contents safely inside. A lighter alternative to traditional paper envelopes, Tyvek envelopes can cut postage rates when mailing your heaviest, most important documents.

DuPont is the sole producer of Tyvek, a sheet material made from spun-bonded polyolefin fibers. It is not a paper, but a plastic with long fibers that give it exceptional strength and tear resistance.  

  • Perfect for bulky mailings - Tyvek’s combined quality of being lightweight and high strength appeals to organizations that have frequent mailings of bulky materials, often in the insurance, financial or legal industry. 

  • Lightweight -  A Tyvek envelope weighing half as much as a comparable Kraft envelope will easily handle twice as much material.
  • Recyclable - Current Tyvek material is completely recyclable and contains an average of 10 percent post-industrial content.

Tyvek is easily recognized by its distinguished look and feel. But don’t let its lightweight appearance fool you. Tyvek envelopes provide a barrier that a paper envelope cannot. Water and moisture resistant, tear and puncture resistant, you can trust Tyvek to deliver. With the highest durability, tear-resistance and moisture-resistance ratings, choose a Tyvek envelope for your heavy mailings. Try to tear a Tyvek® envelope – we bet you can’t!

What Tension Customers are Saying

Tension has a desire to help us help our customers. You don’t get that with every printer or envelope plant. They go above and beyond consistently to help out in whatever way they can.

Jim Laird , Vice President AccuSource Solutions

The team at Tension treats us as though we are their number one client. They treat us like they are a small mom and pop shop, but actually they are a large long-standing national company, and we get that backing. You don’t get that kind of customer service from other large envelope manufacturers.
