All Industries uses corrugated boxes for packaging, shipping, and/or storing – in fact, corrugated boxes increases in demand year after year to fulfill the market requirement. Question is, are you up-to-date with the know how’s?

Well then, here’s the basics you need to know about corrugated boxes.

To identify what size and type of corrugated box is suitable for your needs, you should know what items you’re packing, the size, weight, and how fragile the goods are. Generally, when it comes to item size, you will be thinking mostly of corrugated boxes’ dimension - most commonly stated as Length x Width x Height. Length being the longer side whilst width indicates the shorter side of the box and height gives the depth.

As for heavier goods, the box strength should be top of mind - this depends on their Liners and Medium. Mediums, sometimes called “Flutes” are the ones situated between the liners. There are common types of mediums which is referred to as the following:

  • A Flute 4.5-5mm thickness

  • B Flute 2.5-3mm thickness (most commonly used)

  • C Flute 3.5-4mm thickness (most commonly used)

  • E Flute 1.1-2mm thickness

  • F Flute 0.6-0.8mm thickness

These can also be combined such as BC and ACCC for double or triple wall boxes  – to resist pressure and secure items are packed safely. Common types of walls are as follows:

  • Single face board – One liner attached with a corrugated medium

  • Single wall board – Two liners attached with a corrugated medium in between

  • Double wall board – Three liners attached with two corrugated medium in between each sheet

  • Triple wall board – Four liners attached with three corrugated medium in between each sheet

Single face boards are generally sold in rolls and known as the weakest of the boards. Single wall board is used by most consumers for storing and packing of goods of lesser weight whilst both double wall and triple wall board are for heavy duty shipments to ensure resistance to puncture and collapsing.
