What is a Poly Mailer?


Poly mailers are the lightest way to ship items while also protecting the goods. The PE material (polyethylene) used is co-extruded making them puncture and tear-resistant during the shipping process. These bags help protect non-fragile goods from moisture and provide security by being sealed with a heavy-duty adhesive strip. Not only are our stock white mailers self-sealing, and gray on the inside for opacity for an added level of privacy of the contents inside. Ink, stamps, and labels adhere easily. 

What items work best with these Poly Mailers?


You can use poly envelope mailers to ship a wide variety of individual products/items and is one of the less expensive and best ways for online for companies to mail customers orders. What makes poly mails great for shipping soft goods is they are puncture-resistant, tamper-evident. Being a waterproof envelope they do not only protect your goods from moisture but they help prevent returns orders due to water damage. Items like books, shoes, apparel, accessories, fabrics, and blueprints are perfect for shipping with our standard stock white flat mailers and envelopes. Here are some tips and common sized mailers for shipping common style items packaged in a mailer bag

The first question to ask is, "Are you shipping something fragile?" Very fragile things should consider cardboard boxes and other packaging methods. The best mailer option for semi-fragile items would be our that are bubble-lined mailers. Inside the mailer is lined with 3/16bbubble to protect package contents during shipping. . Sealed the way as the standard flat mailers with the tear-off adhesive strip bubble mailers offer the most protection for softer products and goods.

Another question you should ask Yourself to determine the best size mailer is the size (L, W, and  D) of the measuring the object you are shipping. As a rule of thumb, if an object that's being shipping is bigger than an extra-large pizza box then expansion poly mailers would be your best option

Also, the shape of the object is important to consider for what you are shipping in poly mailing bags. Is the object pretty bulky like a teddy bear? If yes, then you probably won't want to use a poly mailer. Maybe a smaller stuffed animal could possibly fit in our longest poly mailer 13" x 45" Long Poly Mailer.

Poly mailers ship well when they are being used to ship the right individual item. Avoid packaging several different items in the same poly mailer. We have a wide variety of corrugated products for this purpose, like corrugated mailers and boxes.
