Stock & Custom Mailer Boxes, Tubes, and Envelopes

Mailers have become an incredibly popular option for shipping products due to the switch to dimensional weight charges for shipping. They are great for shipping smaller products that don’t need a traditional box. The term “mailers” actually refers to a wide range of packaging solutions:

  • Mailer boxes are easy to assemble due to their interlocking flaps and take up much less space and material than regular boxes.
  • Mailer tubes are incredibly rigid and work great for paper items. They’re also space-efficient, which can create savings on shipping costs.
  • Mailer envelopes are lightweight, durable, and can be padded inside or water-resistant. They work great for small, light, or slim products.

Depending on the type of product you want to ship, Preferred Packaging has several options available to help you find the best fit for your shipping needs.

  • One Piece Folders (OPF)

    One Piece Folders (OPF)

    One Piece Folders (aka OPFs or One Piece Mailers) are made from one piece of cardboard that easily folds into shape. They usually have several layers of cardboard on each end, giving them increased stacking strength and protection. They are great for shipping books, picture frames, and other slim objects.Get Quote

  • Five Panel Folders

    Five Panel Folders

    Similar to OPFs, Five Panel Folders are made from one piece of cardboard, but are divided into five panels or sections. Their construction provides extra stacking strength and protection on the sides, and they're commonly used for shipping long, slim items such as picture frames, metal parts, or MDF pieces (e.g. bookshelf kits).Get Quote

  • Mailing Tubes

    Mailing Tubes

    Mailing tubes are cylindrical containers commonly used to ship posters, documents, and other items that are too wide for an envelope, but too thin to justify a box. They are usually made from corrugated cardboard or plastic and have reinforced end caps. The cylindrical shape makes them incredibly sturdy and prevents them from bending or collapsing during shipping.Get Quote

  • Triangular Tubes

    Triangular Tubes

    When you need extra protection for artwork, blueprints, or other important paper documents during shipping, triangular tubes may be the right choice. Triangular mailing tubes are very similar to cylindrical mailing tubes, but their corners act as extra reinforcements and prevent the packages from rolling around during shipping.Get Quote

  • Padded Mailers

    Padded Mailers

    When your products are too small for boxes or mailers but still need extra protection, padded mailers can be a great solution. Also known as cushioned mailers, these offer much-needed protection from drops, shocks, and vibrations. Common types include Padded Envelopes, Foam Mailers, and Bubble Mailers.Get Quote

  • Non-Padded Mailers

    Non-Padded Mailers

    Non-padded mailers refer to mailer envelopes that don't have any sort of padding or reinforcement. They can be made of Kraft paper or plastic. These are simple, cost-effective, and work well for items that don't need any added protection.Get Quote

  • Disk Mailers

    Disk Mailers

    Disk mailers are very slim and envelope-like. They are made for shipping CDs, DVDs, and BluRays. Disk mailers can usually fit three 3.5" disks or one disk with a case. They have a redi-strip closure that creates a seal to keep out water and dust. There are even mailer boxes made specifically for shipping vinyl records.Get Quote

  • Reinforced Mailers

    Reinforced Mailers

    Reinforced mailers are usually made from Kraft paper and reinforced with heavy-duty nylon threads. This makes them water-proof, tear-resistant, and durable.
