Custom Mailer Boxes: Branded Shipping Packaging for E-Commerce

Custom mailer boxes are custom-made boxes made of corrugated cardboard with a flip-top lid for your product, featuring your branding. They are simple to ship, can be put together inside of seconds, and secure orders in transit. 

They are easy to ship, can be assembled within seconds, and secure orders during transit. Select single-wall kraft or white board to use lightweight products and add an insert to the fragile products.

All online orders culminate in one thing: a customer opens a box. When the box is generic, the brand vanishes. When it is printed, made to fit the product, and constructed to withstand a carrier network, the box does marketing, protection, and retention simultaneously. Empress Packaging is a USA-based manufacturer of bespoke mailer boxes, created to be e-commerce brands around the real product, and the volume of orders rather than a volume chart.

What are Custom Mailer Boxes?

A Mailer boxes is a corrugated cardboard box that is intended for shipping a product without an outside carton. It is unfolded, folds up without the aid of tape or glue and folds or snaps its lid shut. Print is attached to the box, which is the shipping container itself.

The most common type is the flip-top mailer, or roll-end tuck-top box. The lid is hinged and fits like a book, but can be secured with a tuck flap. Typically mailers are made of corrugated board, in kraft or white, and the thickness of the fluting (the wavy layer between the layers) will determine amount of cushioning and quality of print.

Why Not Use Custom Mailer Boxes as a Replacement for Standard Shipping Boxes?

The warehouse is constructed with standard shipping boxes. They guard a product between the dock and doorstep and do not do anything to enhance the customer experience. There are three things that printed mailer boxes alter:

  • Fit: A box cut to your product eliminates the air that allows things to move around, and it does not incur carrier fees due to air.
  • Presentation: Printing transforms the initial physical touchpoint into a branded experience, and this is where unboxing begins.
  • Efficiency: Flat-shipped mailers occupy a portion of the warehouse space that pre-assembled boxes would require, and are easy to assemble when packing.

Benefits of Custom Printed Mailer Boxes

  • Branding: Cardboard Mailer Boxes present your logo, colors and message on every and each doorstep and each and every unboxing photo, with no additional insert or sticker.
  • Protection: The box is the same size as the product, the correct flute, and an insert is used if required, helps to prevent any shifting or crushing, the number one cause of damage claims.
  • Right-size Boxes: Will save on void fill material and have the potential to save on dimensional weight charges (which are based on volume as well as weight).
  • Materials: Recyclable corrugated, recycled content board, and FSC certified materials are available. The printing that is used is water based, and the box does not contain plastic lamination, simplifying its recycling.
  • Customer experience: Easy to open and looks like it`s meant for something, leads to higher perceived value and repeat purchases.

Applications of Custom Mailer Boxes.

Lightweight Flip Top Mailer Packaging are used by apparel and accessories brands, and they can have tear strips to facilitate returns. Bottles and jars are placed in mailers with inserts to keep them in place at beauty and skincare brands. Subscription companies consider the mailer as the whole brand experience, as the box is the first thing that a subscriber views every cycle. Kraft mailers provide a natural appearance at an affordable cost to candle, food gift, and home goods brands. Sellers of electronics accessories combine mailers with paperboard or foam inserts to prevent movement without bulk.

Customization Options

  • Material and board: There are kraft, white, and printed corrugated stock. Selection of flute varies with the product: thinner flutes give more printable results, whereas thicker flutes are more cushioning.
  • Size: Boxes are cut to the product and typical order combination. It is important to get the size correct prior to production, as an oversized box will waste the material, whereas a tight box can damage the product.
  • Printing: Prices go as low as one-color branding on kraft to full-color exterior and interior prints. The cost-effective method of placing a message or pattern on the unboxing is printing it on the inside of the lid.
  • Finishes: Finishes can be either matte or gloss, and both finishes influence recyclability, so decisions on finishes are verified against any sustainability claims you are going to make.
  • Inserts: Products are held fixed in die-cut corrugated inserts, paperboard dividers, and foam options.
  • Closures: Depending on your requirements for returns and wearability, there are standard tuck, tear-strip, and reinforced seam options.

How to Choose the Right Mailer Box?

Start with the product, not the artwork. The board strength is determined by weight and fragility. The volume of orders determines the print technique that is economically viable. And the sales channel will determine the amount of finish to pay an interior print subscription brand will be well-served by a rich interior, whereas a high-volume apparel store might be better served by a single-color brand on kraft. Just in case, request sample proofs of two alternatives prior to a full run.
