Tyvek® is a synthetic material, more specifically highly-dense polyethylene fibers, created by the DuPont company in 1955. What makes the Tyvek® material so unique is the combination of its ability to be both lightweight and strong. The light coating provides a protective seal to a number of items such as car covers, medical packaging, protective apparel, and, of course, envelopes.

Tyvek Envelope Sizes 

Because Tyvek envelopes are most often used to mail large, heavy documents, they often come in large and extra-large open end and open side envelope sizes, such as 6×9, 9×12 and 10×13.   

Tension specializes in custom envelope sizes for our entire product line. Tyvek envelopes from Tension are no different; they’re available in any size to fit your project needs. 

Benefits of Tyvek Envelopes

So what exactly are the benefits of using a Tyvek® envelope?

  1. Lightweight and strong

They are lighter than standard issue envelopes, yet they offer a strong coating.

2. Water and Moisture-Resistant

The coating acts as a barrier to water or moisture making it the perfect envelope to fight the elements.

3. Puncture-Resistant

The special coating allows Tyvek® envelopes to withstand wear and tear. They are puncture-resistant, which means they are great for interoffice mail practices where you have to reuse the same envelope again and again.

4. Printing and Writing

Even with the synthetic coating, you can still print and write on these envelopes. They will work in most standard inkjet printers.

5. Recyclable

Even with the coating, these envelopes can be recycled. However, you cannot just throw them into your office’s blue recycling bin. You have to dispose of them through their nationwide recycling program managed by Waste Management.

Reasons to Use a Tyvek Envelope

Tyvek envelopes are ideal for: retailers or wholesalers who send large, heavy catalogs; insurance companies who send thick policy documents; financial companies who send year-end reports. Builders and construction companies also prefer Tyvek envelopes to protect important documents in environments where they’d otherwise be susceptible to the elements. 

  1. Save on Shipping Cost

Since the coating makes the envelopes so durable, many items can be shipped in smaller Tyvek® envelopes rather than bigger, more expensive boxes.

2. Promotional Materials

The unique appearance that the Tyvek® coating provides gives the envelopes a more distinctive look and feel. They come in a number of colors and sizes that are great for sending out promotional material for your business. You can print your company logo right onto the envelope to give it a unique pop of detail.

Now that you know what a Tyvek® envelope is, get out there and use some for your next mailing promotion, or replace the worn out manila  interoffice mailing envelopes with a more durable alternative.

How much does a PO box cost

How to add Priority Mail Tyvek Envelopes 12″ x 15″ as a shipping option

Question: This envelope is not in the drop-down. When I try to add it as a custom option, Etsy forces me to enter a height measurement, which then calculates the price as a package, not as an envelope. So, it wants me to pay more for shipping as a package even though I’m trying to ship an envelope.

Answer:

For calculated shipping on package preferences, you select custom to enter the size 15″ x 11″ and a height.

You have to enter a height. No way around it. Everything has a height even if just a fraction of an inch.

The rates calculated for the Priority Tyvek envelope are “package” rates.
There is not an envelope rate for these. It doesn’t matter if you ship a flat card in them, fabric, small items, item in a box, it’s still considered a package.

The Priority Tyvek is considered a package/thick envelope and the postage costs is based on the weight and buyer’s zip code.

I don’t know what you’re selling but whatever you’re going to mail in them has to have a height.

You enter the item dimensions + any padding. Do not enter the Tyvek envelope size for the item dimensions.
The calculator uses your item size to suggest a package size from your list in package preferences.

If you have an item that is 13x9x2 and you can get 2 of them in the Tyvek envelope then you need to put the height on the envelope 4″ so the calculator will “fit” 2 in it. Friends, If you only put a 1″ height, then the calculator won’t suggest it at all. If you put 2″ then the calculator will only “fit” 1 item in it.

eBay Sellers; Misuse of USPS supplies can lead to angry customers and fines

An eBay home business is their first experience with any home business for many eBay sellers. They may not realize all the nuances and legalities involved in running a home business, such as tax implications or liability issues for selling recalled or defective products.

One area that newer sellers often misunderstand is USPS mail supplies when shipping. There are several misconceptions about free USPS mail supplies, and all sellers should do their due diligence to understand how these free supplies are used. Misuse of USPS supplies can result in fines from the US government, unhappy eBay customers, and negative feedback.

Usps priority mail supplies

USPS Priority Mail supplies are accessible at the Post Office. These supplies are marked with the USPS logo and “Priority Mail” wording and may only be used for Paid Priority Mail shipping service. Continued misuse may result in the post office charging everyone for these supplies in the future.

The disclaimer on each priority mailbox and envelope reads: 

“This package is the property of the United States Postal Service and is provided solely for use in sending Priority Mail shipments. Misuse may be a violation of federal law. This package is not for sale.

Turning boxes inside out

You’re not as smart as you think, intelligent eBay sellers. It has been going on for years where eBay sellers believe they can outsmart the post office by turning free priority mail supplies inside out so the priority mail branding and USPS logo won’t show.

The Post Office began sealing the inside of its free boxes and Tyvek envelopes with the Priority Mail mark so that if the package is turned inside out, it’s still pronounced what has been done. Countless sellers still tell others to use this strategy to ship items First Class, Select Parcels, or International First Class without paying for their packaging.

Get the right supplies you need to start with. If money is tight, there are several ways to get free shipping supplies in your community. You should also check the profitability of your items for sale and make sure you are selling products that have enough profit to cover the costs of shipping supplies and make a fair profit.

Using USPS envelopes as packing material

Another common misuse of USPS supplies is using the envelopes for packing material. For example, a seller may wrap a small, fragile, lightweight item in a flat rate priority mail-branded padded envelope and then put it inside a simple, low-cost polybag mailer and ship it using the service first class mail.

The USPS prohibits Priority Mail Flat Rate Envelopes or Priority Mail Tyvek Envelopes as packing or packaging material for more oversized boxed items. You are also not allowed to order in bulk or take supplies from the post office to use them as packing material. This type of unethical behavior is costly for the USPS and will contribute to them having to charge for priority mail supplies at some point in the future.

Alter flat rate boxes

Frankensteining boxes are common practice and are allowed when using any non-flat rate box. For example, suppose you are shipping a lamp, and the light is too large to fit in any priority mailboxes.

If you are shipping the lamp using the priority mail service level, you can take several 8x8x12 priority mailboxes and “telescope” them or put them together to make one long tube box. This process is entirely legal. Just not with flat fee boxes. Why? Because Priority Mail shipping charges are calculated using weight, and flat rate prices have already been calculated for each specific size flat rate box.

The same situation applies to padded and cardboard flat-rate mailers. Item must fit entirely inside an ad must close on its own without additional tape. 

Covering priority mailboxes with paper 

It is another big no-no. Covering a box with paper is not a good idea for any shipping service because the form can get caught in the processing machines during transit and be ripped off. The parcel will end up in the undeliverable parcel graveyard. It cannot be returned to the seller or delivered to the buyer because there is no information about the parcel anymore.

As for priority mail supplies, covering them up in paper is a blatant attempt to dodge paying priority mail fees. Just don’t do it.

Fines, unhappy customers, and poor quality shipments

The USPS may assess a fine for customers who misuse Priority Mail supplies, clearly stated in the supplies disclaimer. So maybe you won’t get caught when your poorly packed item is mailed out or picked up by the postman, but the buyer can pay the price.

When priority mail supplies are misused, the item may be delivered to the customer postage due. The buyer will notify to pick up the package at their post office and be charged a fee for postage upgraded to priority mail due to the supplies used.

By taking this shortcut to save a few cents, sellers have buyers with a trip to the post office and demand that the buyer pay more to get their item. It is an effective way to get negative customer feedback and low ratings on your eBay account. 

Get the supplies you need early when you sell on eBay. Find out what boxes and packing materials are required by listing the item and arranging to purchase them. Being prepared is an integral part of being a successful entrepreneur. 

Conclusion:

One in an occasional series to highlight popular products. “Made of high-density polyethylene fibers, Tyvek® has introduced new dimensions of protection, security, and safety in a wide variety of applications.” 

That’s how the innovators at Dupont describe Tyvek. When used for envelope applications, this heavy-duty lightweight can be huge for mailers. 

DuPont’s Tyvek has been around for many years and has a reputation for durability and functionality in the mailing world. It’s a synthetic material which is also used as a first layer to wrap houses which gives you an idea of the durability part.

Tyvek is more expensive than regular paper envelopes but it has one property that makes it well worth considering for mailings; it’s a lot lighter than paper.  Most large envelopes used for mailings are either 28# or 32# weight.  Tyvek’s most common weight is 14#.  So simple math says it’s half the weight or less of paper envelopes.  Going to the next ounce in postage costs around 21 cents per ounce.  So for 1,000 envelopes, you’re saving around $210 per thousand in postage by avoiding the increase in weight of the mail piece – pretty impressive.

The sleek look and smooth feel of Tyvek is pretty much guaranteed to get your mail opened.  It prints really well – even with full ink coverage.  Your brand will stand out and be noticed and the recipient will understand that this is not just any mailing, but rather something important that deserves his attention.

What is a USPS Priority Mail Tyvek Envelope?

It’s virtually impossible to tear which makes it ideal for mailing anything that has rough or sharp edges; like a spiral bound booklet for instance.  It’s also water resistant which ensures it will hold up and look better when delivered especially if it’s raining!

Tyvek is available in a wide range of sizes; from small, credit card size envelopes up through jumbo sizes as large as 22 x 27 inches. Tyvek envelopes are also available with side expansions up to 5 inches for bulky packages. 

 And, perhaps surprisingly, Tyvek is 100% recyclable. A nationwide recycling program collects used envelopes and recycles them into other useful materials. Tyvek itself is contains an average of 10% post-industrial waste content.
