From The Manufacturer

Xpak bubble mailers provide outstanding low cost shipping protection for a wide variety of products. Xpaks are made from poly film with the cushioning of a Duroabubble lining. The poly film is gray on the inside for privacy protection. Xpaks provide excellent tear, weather and puncture resistance. Xpak also has the added security of a tamper evident seal (Hot-melt self-seal closure). An economic alterniative to shipping products in cartons.

An Overview On Bubble Poly Mailers

Whether you’re running your own Etsy shop or you just need to mail a birthday gift to a faraway relative, you probably have a need for some bubble poly mailers. These padded mailers are packed full of useful features. They’re typically built to resist tampering, accidental tearing and water exposure — all in a lightweight build.

Best of all, you can buy bubble poly mailers in a variety of colors. Instead of the standard whites and tans typically seen with paper mailers, poly mailers come in bright pastels that stand out. This is especially useful for business owners trying to establish a brand. Simply use a stamp to place your logo prominently on the mailer somewhere and, combined with the color, your customers will come to recognize your items in the day’s delivery.

But not all poly mailers are equal. First, it’s important to pay attention to the material itself. It should be thick polyethylene to provide full water- and tamper-resistance. Second, look for an adhesive seal on the flap that will keep your mailer secure and tamper-proof no matter what it encounters on its route from your place to your recipient.

You’ll also want to look at the interior. Most poly mailers come with internal bubble wrap insulation. You’ll want one that’s thick enough to allow room for your items while also offering the protection you need.

The Bubble Poly Mailer Buying Guide

  • One of the most important factors to consider when you’re choosing poly mailers is size. You can always squeeze smaller items in a bigger mailer, so it’s best to choose one that handles your biggest items. If you regularly ship items in a variety of sizes, consider buying multiple sets to cover everything.
  • Bubble wrap is measured in grams per square meter, or GSM. The higher the number, the better. If you’re looking for smaller, densely-packed bubbles, a mailer that has 40 GSM should do it, but you can find bubble wrap as thick as 300 GSM.
  • Although poly mailers are great for shipping everything from trinkets to books, they don’t provide protection against being bent or folded. If you’re mailing something that needs to be kept flat, insert thick cardboard. Also consider writing or stamping “Do Not Bend” on the outside of the envelope near the address label.
  • If your items weigh under 13 ounces, the U.S. Postal Service is the least expensive option. As you drift above that, you should consider pricing FedEx and USPS. If you’re selling products of the same size, and your plan is to ship those items regularly, it’s well worth pricing multiple carriers and packaging options to make sure you’re giving your customers the lowest shipping costs possible.
