Pros:Lightweight, tear & puncture proof, water resistant.

Cons:more expensive than regular envelopes

The Bottom Line: More expensive than typical envelopes, but worth it. lightweight & I can know that the contents are safe from almost anything the postal service can do to my packages.


I started selling on ebay a few years ago. One of the biggest problems I came across was decent shipping envelopes. I wanted something that was sturdy, but light enough not to add any weight and increase shipping costs. I loved the performance of the Postal Services Priority envelopes. But there are often times that it's not cost effective for me to ship priority. Survivor Tyvek Envelopes gives me the same durability and lightweight material that I can use with parcel post or even 1st class.

The material

Tyvek looks like a fiberous piece of smooth, bright white, ultra thin paper. But unlike paper it cannot be ripped or torn. It is also water resistant. It is made from 25 percent post-consumer recycled content and is also recycleable itself.

From tyvek.com:

Made from very fine, high-density polyethylene fibers, TyvekŪ brand protective material offers all the best characteristics of paper, film and fabric in one material. This unique balance of properties, which cannot be found in any other material, makes TyvekŪ lightweight yet strong; vapor-permeable, yet water-, chemical-, puncture-, tear- and abrasion-resistant. TyvekŪ is also low-linting, smooth and opaque.

Performance

I have yet to have one open or rip in transit. Nothing inside is ever damaged. Keep in mind though that these are NOT padded envelopes. They are not meant for fragile items, unless you wrap the item well before putting it in the envelope. Most of the things I ship are clothing items and books.

They have something called a release strip feature, which is a section underneath the flap that is perforated so it's possible to open it easier. But personally, I don't like the thought that it's easier to open. I want it sealed up as tight as possible, so I usually make sure to place the flap in a position that does not allow the release strip to work.

The Bottom Line

They are more expensive than typical envelopes, but not by much (if you hunt the internet for good deals). But I think it's worth it because they are so lightweight they add so much less to the cost of shipping. Plus I can rest assured that the contents are safe from almost anything the postal service can do to my packages.
