There are two components to a corrugated cardboard sheet — linerboard and the medium. The linerboard is what you see right away, the smooth pieces of cardboard on either side of the sheet. In between these pieces is the medium, which has arched or “fluted” paper inside that forms vertical columns and enhances the weight-bearing limits of the sheet.
Two tests can determine the strength of corrugated cardboard and how much weight it can carry without losing its integrity. The Mullen Bursting Test measures the bursting strength of the board, making it a useful measurement when you’re looking at support for heavy objects. The Edge Crush Test measures stacking strength, an essential determining factor for lightweight boxes that you plan to stack.
The best way to determine these measurements is to check the Manufacturer’s Certification Stamp, which you can usually find on the box’s bottom flaps. You can find other important box strength guidelines on this stamp, such as whether the box is single-wall or double-wall, the maximum interior size of the box and its weight limit.
Whether you’re shipping items just down the street or halfway across the world, you never know what could happen to a package after it leaves your business and before it reaches a customer’s doorstep. It may be stacked, thrown and dropped — more than once. You’ll want to ensure you have a box that can adequately protect your products from any potential damage during shipping. Using corrugated boxes is an excellent start. Some items require specialized packaging to keep them safe in transit.
Your box should still hold its integrity when it arrives at its final destination. Even a beautifully customized box can fall flat if it shows up dinged and dented. If you want to leave the best impression possible, you should ensure that your products are within the size and weight limits allotted for any particular box. When you ship particularly fragile or heavy items, consider ordering our strong or extra strong boxes.
