What are corrugated boxes? If you’re still not familiar with the world’s best packaging option, then you’re in the right place. 


If you would like to learn more about corrugated boxes, as well as the different uses and types of corrugated packaging, you’re in the right place!

  • How do you properly measure the size of a box?
    Box size always refers to the inner dimensions and appears in the order of length, width, and depth. Box length refers to the longest side of the opening, width refers to the shortest, and depth to the distance between where the box opens. Pad dimensions always appear in the order of width and length, where width is the direction of corrugation.
  • What are flutes?
    Flute refers to the profile of the corrugated medium. 'C' flute is the most common, followed by'B', with both bei ng readily available and carrying the same cost. 'BC' is the combination of 'B' and 'C' and is commonly referred to as double-wall. 'BC' is re adily available and is typically used for packaging that has material requirements beyond what 'C' or'B' (single-wall) can provide. 'E' flute is also readily available but carries a higher minimum quantity and cost than 'C'or'B'. 'E' flute is ideal for smaller packaging and has a superior printing surface.
  • Can you explain the difference between ECT vs. Mullen?
    Edge Crush Test (ECT) is a high-performance board developed as a less expensive alternative to Mullen in cases where the primary focus is on stacking strength. One popular myth about ECT is that it is made from 100% recycled Old Corrugated Containers (OCC) and is therefore not as reliable as Mullen. The truth is that both ECT and Mullen contain onaverage 43% OCC. The real difference between ECT and Mullen is that Mullen's paper fibers are crossed as opposed to ECT where the paper fibers are aligned. These aligned fibers give ECT a similar stacking strength to Mullen at a lighter basis weight, but at the cost of bursting strength.
  • Are corrugated boxes the same as cardboard boxes?
    Although commonly used interchangeably by people outside the box industry, cardboard boxes are not the same as corrugated boxes. Cardboard boxes are made of a variety of pulp paper. For example, stiff chipboard is typically used to make a shoe box. Thinner chipboard is used in folding cartons such as a toothpaste or cereal box. Both of these are cardboard boxes. Corrugated boxes are stronger. They are made of a combination of flat linerboard glued to a fluted medium. Both the linerboard and the fluted board are made of sturdy kraft paper called containerboard. This is the same kraft paper used in grocery bags. Corrugated boxes can be used as shipping boxes that carry multiple cardboard boxes. Cardboard boxes are not strong enough to be shipped by themselves. They need to be packed in corrugated shipping boxes.
  • What are the different types of corrugate?
    There are many different types of corrugate. Single Face boards are fluted (corrugated) medium and a single sheet of flat linerboard glued together. Single wall or double face is similar, but it has two sheets of liner board, one on each side of the fluted medium. Double wall has three sheets of liner board that are glued to two fluted board. Triple wall has four sheets of liner board glued to three fluted boards. Triple wall is less common but extremely strong. You can ship watermelon in a triple wall box.
  • What is an FAQ section?
    An FAQ section can be used to quickly answer common questions about you or your business, such as “Where do you ship to?”, “What are your opening hours?” or “How can I book a service?” It’s a great way to help people navigate your site and can even boost your site’s SEO.
