What is postal packaging?

As the name suggests, its primary use is to protect products through transit. You’ll see this type of packaging used by e-commerce retailers, as the name can encompass many different styles. For example, postal tubes, mailing bags and cardboard envelopes are all types of postal packaging.

Choosing the right postal solution for you

The best postal packaging solution for your products depends on several factors. Below is a handy overview of the main types and their applications to assist you in making an informed decision:

  • Bubble envelopes – If you’re shipping small items that require lightweight protection, bubble envelopes are an ideal postal packaging option. Many bubble envelopes come in letterboxable sizes, so they’re ideal if you’re looking for packing materials that fit Royal Mail postage formats.
  • Plastic mailing bags – Perfect for posting items that don’t need heavy-duty protection. A popular choice for fashion and clothing brands. They’re also a waterproof option!
  • Paper mailing bags  – Paper mailing bags are a recyclable alternative to traditional plastic mailing bags and can be used for similar applications. They come with a self-seal strip for easy closure.
  • Postal boxes – Our postal boxes are suitable for items that meet Royal Mail small parcel guidelines. They are an eco-friendly postal packaging option that contains high recycled content and can be recycled.
