There are a lot of things to consider about Manila, like why they are called Manila, or what the right sizes for your documents are, and what the standard sizes available in the market are. Let’s delve deep and explore them all. 

Why does the Manila envelope have a unique name?

The name of the envelope comes from its origin, where it’s manufactured. Manila Paper is made of Manila fibre, so the same name is used for the envelope as well. These envelopes can be customized regarding colors, materials, and sizes, but it will cost you more during the shipping process.

Durability and Protection

The sturdy paper stock of the Manila envelope makes it strong enough to withstand tearing, bending, and creasing. You can keep your important documents flat and secure easily.

Size and Capacity

Manila envelopes do not bind you to one size only, like standard #10 envelopes. You can get the right envelope, like letter size, legal size, or whatever you need. 

Mailing vs. Organization

The unique design of the Manila envelope makes it ideal for physical organization. You can use them at the office or at home for filing, storing, and transportation.

Clasp or String & Button Envelopes

You can stick with a gummed flap, if you want, but many Manila envelopes have a string tie or metal clasp. Many businesses use these secure and reusable closures to keep their documents from damage.

What are the Disadvantages of not using Standard sizes for Manila envelopes?

Limited Availability and Higher Cost

When it comes to manufacturing, the standard sizes are produced in bulk and are readily available that making them a more affordable choice. You need to custom-order your non-standard size, leading to an increase in the cost per unit.
