What is Tyvek Envelope: Origins
The Tyvek envelope comes from the vaunted DuPont company, and it leases the use of the material to several brands of envelope makers.
To refresh your memory, the DuPont brand is behind some of the world’s most crucial inventions.
This is the company responsible for nylon, Lucite (Plexiglas), freon (AC cooling agent), Kevlar (bulletproof armor), Teflon (nonstock cooking utensils), and Lycra (elastic polyurethane fabric for sportswear).
The Tyvek envelope was actually developed way back in 1955, and these poly mailers still set the benchmark for envelope toughness even now.
What is Tyvek Envelope: How Is It Made?
This envelope isn’t made of regular paper, though it may seem that way at first glance.
It’s really made from extremely dense polyethylene fibers.
The fibersgo through a special patented flash spinning process developed by the Dupont company.
It is then laid out in a web pattern and set on a moving bed.
The process applies pressure and heat to the fiber web.
This leads to a sheet of dense PE fibers that can be shaped into envelopes.
What is Tyvek Envelope: What Are the Benefits?
Lots of people opt for a priority Tyvek envelope for several reasons:
It’s Extremely Tough
Comparing a Tyvek envelope to a regular paper envelope is like comparing a Navy Seal to a regular out-of-shape Joe in the street.
The Tyvek envelope is simply a lot stronger and much more durable.
It’s much less likely to rip or tear while in transit.
Remember how postmen aren’t supposed to be deterred by rain?
The same goes for the Tyvek envelope as it’smoisture resistant.
All of these envelopes are coated with a special compound that protects against moisture.
That means if you’re sending crucial documents like contracts and birth certificates over the mail, you minimize the risk of water damage along the way.
These envelopes do not puncture very easily.
This is in contrast with regular envelopes, which may tear when brushing against sharp edges.
Flimsy envelopes may even tear if it contains heavy-papercatalogs with pointed corners.
But with the Tyvek envelope, this risk is reduced due to that water-resistant coating.
That coating also adds another layer of strength, which minimizes the wear and turn.
That’s why you may even find yourself reusing Tyvek booklet envelopes.
There have been movies that sometimes show unscrupulous criminals opening and resealing envelopes being sent through the mail system.
In these movies, they’re able to reseal the envelopes without leaving any trace that it’s been opened.
But with the Tyvek envelope, that’s not going to happen at all.
If you open a sealed Tyvek envelope, it will be very obvious that you removed the seal.
There’s no way to surreptitiously seal it back again.
Lots of companies these days are into recycling programs, and these include DuPont.
DuPont has a recycling program for these envelopes, so that the materials don’t just end up in the dump.
In this day and age when people are more concerned about recycling, it’s a crucial feature.
With all of its touted toughness and durability, something like the Tyvek USPS may seem heavy.
But it’s actually lightweight, so it’s even cheaper to send it over the mail system.
What is Tyvek Envelope: What Is the Main Disadvantage?
The Tyvek envelope isn’t perfect, however.
One of the main disadvantages is that it’s not always easy to set the recipient address (or the sender address) on it.
You can use a permanent marker, and some ballpoint pens and pencils may work.
But some kinds of ink may run on the surface of the envelope fibers.
Can’t Use with Laser Printers
You also can’t use it with laser printers, at least not directly.
Using a laser printer results in heat production, which melts the fibers of the envelope.
This may even damage the laser printer itself.
If you still want to use the printer, print the address on adhesive labels that you can then stick to these envelopes.
