If you’ve ever mailed anything besides a letter (or worked in logistics, for that matter) then you’re likely well aware that there are many different types of envelopes (and shipping containers!) that are specialized to the needs of the post or the freight being shipped.
Case in point: expansion envelopes, which look like regular mailing envelopes, but which have a few distinguishing features that make them more suitable for mailing larger, bulkier (though generally still light) parcels.
Here’s what you need to know, per some of Google’s top searches.
What Is an Expansion Envelope?
In many ways, expansion envelopes are like regular paper mailing envelopes and are even available in many of the same standard sizes, such as 5”x11” and 9”x12” (among others).
However, expansion envelopes are made with side gussets that enable them to expand as needed. For this reason, these types of envelopes are often categorized with a third dimension, that you can see among their specifications. For instance, there are 9”x12”x”2” envelopes that expand 2” to accommodate larger parcels.
What Are Expansion Envelopes Used for?
Expansion envelopes, like regular paper envelopes, are used to mail small parcels, typically consisting of paper or other documentation. However, they can also be used to mail other light, thin packages, such as thin clam packs.
The design of expansion envelopes makes them perfect for:
● Large, thick packets
● Binders and portfolios
● Catalogs and magazines
● Books
● Computer reports
● And even small packages
What Are They Made from?
While many expansion envelopes are made from paper, there are many other different styles of envelopes to consider.
In addition to paper, many envelopes are made from synthetics and post-consumer recycled materials, such as FibercraftⓇ, which is an environmentally-friendly, partially-recycled material that is tear resistant and fairly rigid. Another commercially popular synthetic material is HerculinkⓇ, which is not only tear and burst-resistant, but water-resistant as well.
Other expansion envelopes are made of polyethylene which is cheap, affordable, and strong. Moreover, there are special bubble expansion envelopes that are more suitable for mailing small packages and parcels that are slightly more fragile, but which do not necessarily need to be shipped in a box.
Expansion Envelope Sizes?
The common search on Google is “what is the size of an expansion envelope?” but that is a cumbersome query, so instead we will offer some of the standard sizes, which include but are not limited to:
● 5”x11”x2”
● 9”x12”x1”
● 9”x12”x2”
● 10”x12”x2”
● 10”x12”x4”
● 10”x13”x1”
● 10”x13”x2”
● 10”x15”x2”
● 12”x15”x3”
● 12”x16”x2”
However, even though these are some of the more common sizes, there are many other sizes available.
