Knives to Open Taped Cardboard Boxes [Video]

This guide will show you how to use a safety knife to protect both the package contents and yourself

Opening taped cardboard boxes efficiently and safely requires the right tool—a specialized cardboard knife.  Whether you're unpacking a single parcel or managing goods in a warehouse, the type of knife you use can make a significant difference. Here are expert tips for using a cardboard cutting knife to ensure safety for both the user and the contents of the box.

Select the Right Knife

Not all knives are suitable for cutting through cardboard. The best knife for cutting cardboard is specifically designed to handle the durable and often sticky nature of taped boxes without causing damage to the contents inside. A cardboard cutter knife typically features a retractable and/or shielded blade to minimize the risk of accidents.

Choosing the best knife for cutting cardboard is crucial. Opt for a safety knife, like a foil or pelican knife, which is designed to cut through tape without damaging the contents inside due to its upward-angled blade. These knives ensure that the blade does not come into contact with the contents of the box.

Use the knife blade to cut the tape on the side of the box and then you can press the tape over the opening. It’s much more efficient and safer to open taped cardboard compared to other knives. Always cut only the tape to avoid damaging the box’s content.

The advantage of using a safety knife, foil knife or pelican knife to open taped cardboard is that you protect the contents when you cut because the knife blade is angled upwards instead of inwards the contents of the cardboard. The knife blade thus does not access the contents of the carton.

Another advantage of using a safety knife, foil knife or pelican knife when opening taped cardboard is that it is safer for the user because you can practically not cut yourself by the safety knife.

When you have removed the contents of the opened box, flip over the box and remove the tape on the underside. Then just fold the cardboard so it takes up minimal space in the recycling bin.

Safe and Efficient Opening Techniques

• Proper Blade Use: Only cut the tape to avoid damaging the box's contents. Position the blade at the side of the box and gently press through the tape.
• User Safety: The design of the cardboard box cutter knife minimizes the risk of injury. Its safety features prevent the blade from accidental exposure.
• Post-Opening: Once the contents are removed, fold the box down to minimize space in the recycling bin by removing the tape on the underside.

To safely open a box:

• Position the box: Ensure the box is stable on a flat surface.
• Correct blade depth: Adjust the blade depth of your best knife to cut cardboard so that it just pierces through the thickness of the cardboard, not any deeper.
• Cut away from your body: Always push the knife away from your body and keep your other hand at a safe distance from the cutting line.
• Follow seams and edges: Start your cut at the seams or where the tape is evident, following along the edges for a clean cut.
