What is a “48hrs item”?

When you order online, your boxes will be ready to ship 48 hours after you approve the spec. This is available on all of our custom boxes style. Look for the purple 48hrs banner on the pictures. See all the details here (link to the 48hours custom boxes page).

Why aren’t all the styles available to ship in 48hrs?

To ensure we can deliver on our 48hr promise, we chose styles of boxes that are most common and fastest to manufacture. We also excluded any special corrugated (white liner, water resistant and other special coatings, etc) which take longer to produce or require a higher minimum quantity. These options are all available through our regular manufacturing service, with a 5-10 business days lead time.

What if I don’t need to receive my boxes in 48hrs?

Use coupon code “NORUSH” at checkout to receive 10% off your order. Please note that this coupon code will only apply to the items which are eligible for 48 hour shipping. Your boxes will ship between 5-10 business days.

How do I measure a box?

When measuring a box, always use the inside dimensions. If your box is already assembled, take a ruler or a tape measure and measure the inside distance between each side of the box. If your box is flat, measure from the middle of the score (fold) to the next score. With each box style, there is a diagram showing where to measure, whether your box is flat or assembled. If you are having difficulties, contact us and we will help you get the measurements right. It is important that you measure your box correctly because we are not responsible for boxes that are ordered with the wrong dimensions.

What is the flute and how is it important?

When you look at a corrugated cardboard sheet from the side, the arches that you see are called the flute. Flutes are denominated by the letters A, B, C, E and they can be combined to give the corrugated sheet more strength. This will create a double-wall corrugated cardboard denominated by 2 letters: BC, AC, etc. The letter is associated with the number of “arches” by linear foot and the height of those arches as detailed in the table below.

Flute Designation Flutes per linear foot Flute thickness (in) Flutes per linear meter Flute thickness (mm)
E flute 90 1/16 295 1.5 mm
B flute 47 1/8 154 3 mm

C flute

39

3/16

128

4 mm

BC flute

-

9/32"

-

7 mm

In order words, the flute represents the overall thickness of the cardboard and its strength when force is applied parallel to the flute. Combined with the ECT (edge crush test) number, the flute is used to identify exactly which type of corrugated board is used to create a box (or pad, divider, tray, etc). This information is typically found on the bottom of the box, in the “Class Stamp”.

How is this important? First you need to identify whether you need a single wall, or double wall box. Single wall will be identified by only one letter, and double wall will be identified with 2. Depending on the class stamp, it might also be identified with the words “single wall” or “double wall”. If this information is not available to you, we recommend you use double wall if you plan to ship your products by courier (FedEx, UPS, regular mail, etc). If you ship your products on pallets, single wall is commonly used, but depending on the weight you put in boxes, you will have to choose between different ECT or Edge Crush Test

What are board test / ECT, and how do I know which to choose?

The board test or Edge Crush Test (ECT) is the amount of force in psi (lbs per square inch) that can be applied to the cardboard, parallel to the flute. This will be identified with a 2 digit number on the class stamp. Here is a table of the most commonly used ECTs in the packaging industry:

 

Edge Crush Test

Mullen Test

Maximum weight (box and contents) in lbs

Maximum outside dimension (length , width, and height added) in inches

In order to decide which ECT to choose, there are 3 critical pieces of information you need:

1. Will you be using Single wall or double wall?

As a rule of thumb, choose single wall if shipping your boxes on a pallet, and double wall if you plan to ship by courier (FedEx, UPS, Postal service). See our flute section

2. What is the weight of the items you will be packing in your box?

How much will your box weigh when filled? (in pounds)

3. What are the maximum outside dimensions?

To calculate the maximum outside dimension, add together the rough dimensions of the item you are packing in inches (length + width + height)

Using this information, you can use the table above to determine which ECT you need.

This table is used as a reference only. Keep in mind that if you are shipping something very heavy / expensive / fragile, it is always better to get in touch with one of our designers to ensure you get the best packaging. Protective packaging is our specialty and our design services are

The ETC information should also appear on the box’s class stamp. If you see a 3 digit number on the class stamp, it is referencing an older system for measuring box strength called the Mullen Test. You can use the table above to find the equivalent ETC number. For example, a box labeled “200 C” will be equivalent to a 32C in the ETC system.

Still not sure which ECT you should choose?

The higher the number, the stronger your box will be. This means that you can stack more boxes on top of each other without the risk of them collapsing and crushing your products.

If you are using single wall and shipping your boxes on a pallet, 32 is the most commonly used. If you know your products are heavy, 44 will provide the best stacking strength. If your products are light and you want a budget friendly box, you can choose 29. If your products are not so heavy but you know they will be stacked, 40 would be a good choice. Again, if you are note sure, you can always call or click to chat with someone from our team. We will be happy to assist you!

What is a class stamp?

A class stamp is a printed logo usually found on the bottom of a corrugated box. It will contain all the information regarding the type or corrugated board used. It can be very useful if you have a box and you want to order the same thing. Class stamp will use either the ECT, Mullen System, or sometimes both. Here are some examples of class stamp you might see on boxes.

Why isn’t the “Add to Cart” button available?

The “Add to cart” button will become active once you fill out all the information needed to create your custom box. If it is faded and nothing happens when you click, you might have forgotten to enter information. Go back and look for required fields that might be blank. If you see some fields marked in red with an error message, we might not be able to calculate a price for your box online but that doesn’t mean we can’t produce it. Give us a call or click to chat and we will be happy to quote your box.

I get an error message when entering my box dimensions. Can you still produce my custom box?

Yes. If you see an error message stating the the combination of width, length and height is too small or too large, this doesn’t mean we can’t manufacture your box. It is our design team’s specialty to come up with solutions to meet your needs. Please click, call or chat to contact us and we will find a packaging solution that fits your needs.

Is there a maximum number of boxes I can buy?

The maximum number of boxes you can order online is 10 000. If you need more that 10 000 boxes you might be eligible for a better price. Please click, call or chat to contact us to speak to a member of our team.

If you choose to use our 48hr service, the maximum allowed will be lower. All the details are explained on the 48 hour service page.

Is there a minimum number of boxes I can buy?

There is no minimum amount of boxes you can buy online.
