Your Options For Small Shipping Boxes

Small shipping boxes come in many shapes, sizes and materials. Prices vary based on size and material, while some are 100% free.

Here are the most common types of small shipping boxes used in eCommerce.

1. Corrugated Cardboard Boxes

Corrugated cardboard boxes are the most popular type of small shipping box. Cardboard makes a study container for smaller items, including fragile items. You can get small cardboard boxes that fold open, slide open, and more.

Small cardboard shipping boxes are available at small, extra small, and mega-tiny. You can buy boxes made for shipping items like jewelry or even DVDs (thanks, USPS). A few common box dimensions you’ll find include:

  • 3 x 3x 1.5”
  • 3 x 3 x 3”
  • 4 x 4 x 4”
  • 6 x 6 x 2”

Every shipping company accepts cardboard boxes for shipments.

2. Custom Small Shipping Boxes

Custom boxes are personalized to your brand. Typically made of cardboard, the box exterior is stamped with your company logo or other messaging. Doing so helps your customers to remember their unboxing experience, which leads to customer loyalty and repeat purchasing.

Custom boxes can be ordered as small as you like. For example, the custom box company Uprinting lets you set your box dimensions as small as 3 x 2 x 1, as seen here:

Custom boxes aren’t cheap, as far as packaging goes. You’ll pay somewhere around $1 per box at the least. That said, wowing customers with a specialty box may be vital to a repeatable brand experience – and totally worth the spend.

3. Insulated Shipping Kits

Insulated shipping kits are actually two boxes in one. There's an outer cardboard box, and the styrofoam/polyurethane container that fits inside. The dual box design keeps the inner container air-sealed and temperature-controlled for up to five days. You can use insulated small shipping boxes to send delicate items, including medical supplies or food.

Small insulated shipping boxes are more expensive than regular boxes. That said, how else are you going to ship ice cream?

4. Poly Mailers

A poly mailer is a lightweight yet sturdy plastic bag designed to ship non-fragile products. Just affix the shipping label to the bag exterior, and the top is self-sealing.

Poly mailers come in a variety of smaller sizes, including:

  • 4 x 8”
  • 5 x 10”
  • 6 x 10”

Poly mailers are an inexpensive alternative to small shipping boxes. They come in a variety of sizes, colors, and materials. Using a poly mailer instead of a box can help reduce your package weight, which, in turn, helps reduce your shipping costs.

Poly mailers are best for sending items that won’t break in transit, like apparel or pre-packed items. Most locations that sell small shipping boxes also offer poly mailers.

Where to Buy Small Shipping Boxes

Where can you buy small shipping boxes? Well, almost everywhere that offer shipping boxes also offers small shipping boxes. Here’s the Easyship shortlist of ways to get cheap small shipping boxes.
