Frequently Asked Questions
about Designing Custom Shipping Boxes

Choosing a Shipping Box

Should I choose a shipping box or a mailer?

If you are shipping something heavy or bulky, or if you typically ship a combination of different items at a time, shipping boxes are likely the best fit for your business. We also recommend shipping boxes - especially custom printed shipping boxes - to companies that really want to deliver an exceptional, unique delivery experience (though we do believe branded mailers can wow your customers as well). If you’re debating between a mailer and a shipping box for your business, it is helpful to remember that mailers are less expensive, use less material (making them more sustainable), and allow for a lower cost of shipping to your customers. Learn more.

What style of shipping box should I use?

EcoEnclose offers a handful of box styles. Big picture, they fall into three categories: presentation style boxes (which include tab locking and literature mailers), standard boxes (regular slotted containers, five-panel folds), and flat boxes (one-panel fold boxes). Read on for details of each and when we recommend using one over the other.

custom shipping box - tab locking style
Tab Locking Box (TL)

These are the boxes we recommend the most and sell the most. This is the classic presentation style box that is used by many brand-conscious eCommerce businesses to create a wonderful unboxing experience for the customer. Their logo and branding look great on the lid of the box. The locking tabs create a clean seal for the box and get the sealing tape on the bottom corner of the box versus the top edge of a Literature Mailer or the across the top of a Regular Slotted Container. These are ideal for most eCommerce products, including apparel, accessories, cosmetics, small toys, outdoor wear. Avoid the TL when shipping large boxes (greater than 15” x 15”) or heavy goods (>15lbs).

custom shipping box - literature mailer style
Literature Mailer (LM)

Very similar in design to the TL box, this box style can be used for the same items. Because the material footprint is essentially the same, we offer the same price for LMs and TLs. Thus, for most customers, the choice between a TL and LM is based on aesthetic preference. The LM has the seam on the top edge of the box versus the bottom edge of the TL. The LM’s lid rests on the sides of the box, which hides the side seams and folds that see on a TL. However, the LM is quicker to assemble due to the lid folding into the box versus the TL’s two tabs that fold into slots.

custom shipping box - regular slotted container style
Regular Slotted Container (RSC)

RSCs are the traditional industrial box seen throughout life. Think moving boxes and Amazon boxes. Each side has a tab that folds over and the seam is taped shut on the top and bottom of the box. RSCs are great for heavy products (>15lbs) and deep box sizes (>6”). Many customers use RSCs when packing wrapped fragile items in packaging paper or packing heavy items such as books, liquids, or ceramics.

custom shipping box - five-panel folder style
Five-Panel Folder (FPF)

Very similar in design to the RSC, except FPFs have an extra inside flap that reinforces the structural integrity of the box. This design is best for tall or long items such as a wooden sculpted Statue of Liberty, a skyscraper model, or a baseball bat.

custom shipping box - one panel fold style
One Panel Fold (OPF)

In a class all by itself, the OPF is a great box for slim to flat items such as picture frames, prints, books, and jump ropes. The OPF flaps each fold around the product and meets on the backside of the box, creating a very clean front panel with no seams. The OPF looks great when printed. Several variations can make these boxes very quick to pack. For example, we have developed a wrap-around OPF that allows you to wrap the product versus folding over each of the four sides. The OPF is a great way to quickly package large volumes of the right product.

custom corrugated pads for shipping
Corrugated Pads

These typically serve one of three purposes:product divider, additional compression protection to your product, or increase rigidity of a print: Used frequently by artists when shipping with mailers, a corrugated pad adds additional rigidity to your print to reduce the chance of bending during transit. Scored pad dividers can separate two or more products within your box and provide more visibility, attention, and protection to each piece

Shipping Box Sizing

How do I measure my custom boxes for shipping my products?

EcoEnlose is focused on providing completely customized boxes so they are the exact size you need them to be. This helps you minimize extra, unnecessary air within a box – for more eco-friendly shipping that is less expensive and more visually appealing.

If your vision is to make the box fit perfectly around your items, then a simple guideline would be to add 0.125" to the length and 0.125” to the width (and keep the height the same). If you are going to use void fill, then consider what type and how much fill you plan on using, and add this “cushion” to your dimensions.

Note that the dimensions you input on our site for boxes refer to the inside dimensions of the box you’ll receive. If you have any doubts, we recommend that you order a sample prior to stocking up.

Why can't I order certain size shipping boxes?

Due to the capabilities of our machinery, there are some restrictions on the sizes of corrugated boxes we are able to cut and the sizes we can custom print. If you input box dimensions that we cannot cut or cannot print, you will see an error message. To learn more about our parameters and what we offer, contact us here.

Why are large shipping boxes expensive to ship?

We ship our shipping boxes flat. As such, oversize boxes can often be cut, but are extremely expensive to ship.

Shipping Box Strength, Fluting, and Folding

What is fluting, and which should I choose for my mailer boxes?

Fluting refers to the characteristics of a corrugated sheet's actual middle (wavy) layer. Flutes vary in two main characteristics – their height (which creates the thickness of the cardboard sheet) and how tightly or loosely they are waved or “fluted.” EcoEnclose offers B flute, C flute, and E flute, and a range of strengths (which refers to the amount of weight that can be placed on a corrugated sheet standing straight up and down).

We recommend 32ECT E as the best fluting for presentation-style mailer boxes (Tab Locking Boxes and Literature Mailers), particularly for smaller dimensions. B flute works better for large presentations mailer boxes (as B flute doesn’t bow the way E flute will on a large box). For RSC or FPF boxes, choose 32C if your shipment is fairly light and 44C if you are shipping very heavy items and/or needing very large boxes. Learn more.

How do you fold a shipping box?

If you’ve never folded a tab locking box and aren’t sure where to start – our tutorial videos are for you. As a bonus, they will work for our ecofriendly literature mailers as well.

Shipping Box Custom Printing

What is your most sustainable printing ink?

Even the most sustainable (water and soy-based) inks are made with carbon-based pigments. We are proud to offer Algae Ink for black box prints.

Algae Ink, made by Living Ink Technologies, is the world's most sustainable ink. It is a water-based (i.e. water is the carrier) ink whose pigment is made with algae cells, rather than carbon. This exciting advancement in ink has actually been shown to be a carbon negative technology. Algae Ink captures more carbon than is used to produce it! If you're interested in using Algae Ink for your custom printed shipping boxes, select ALGAE INK as your color option.

Still not sure why Algae Ink is so cool? Explore Algae Ink for a rundown.

How much do your printing plates cost?

We have a tiered pricing structure for printing plates, based on the type and size of your box and the number of panels you intend to print. Plate prices start at $95 for a single panel print, average about $200 for a mid-coverage print, and can be $300-1750 for a full coverage print. A plate cost is incurred for each printed color and printed side of the shipping box.
