Poly mailers are a good investment for business or even home use when you need to send a lot of things that don't want to be opened during shipping.
This type of plain poly mailer is unique because of the material it is made up of that is polyethylene. Polyethylene is extremely durable and practically tear-resistant. This makes it ideal for any sensitive document you want to send by post.
Millions of people lose something in the mail every year for one reason or another. This could be due to losses by postal service providers or simply due to illegal opening. To avoid such situations, polyurethane prints have a unique adhesive and are much stronger than your standard envelopes or other postal items.
You can usually find polyethylene mailers in a variety of sizes. They are made in sizes to fit from standard documents to whole big documents.
They are often much more expensive than standard envelopes, but the added security they offer is well worth it. If you buy it for business purposes, there are specialist manufacturers who will sell it to you.
Whether for business or personal use, poly mailers are a good investment. It might cost a little more money to buy, but you can rest easy knowing that whatever you put in one of these letters and seals will get to your destination safely.
