The Can Opener Hack for Opening Stubborn Plastic Clamshell Packaging

The easiest way to open hard plastic clamshell packaging may be sitting in your kitchen drawer: a standard, manual can opener. Clamp it onto the sealed rim, turn the knob, and the cutting wheel can slice along the edge, leaving a smooth cut instead of jagged, finger-slicing plastic.

Why Is Clamshell Packaging So Hard to Open?

Is there anything more frustrating than buying a new pair of scissors, a charging cable, a set of wireless earbuds, or a kid's toy, only to find it completely sealed inside that impossible, thick, clear plastic? You know the kind—the infamous clamshell packaging. It seems practically bulletproof. You try pulling it apart with your bare hands, then you grab a kitchen knife (which is always dangerous) or bend a pair of scissors, and eventually you manage to hack it open, leaving behind jagged, razor-sharp plastic edges that can cut your fingers.

The can opener trick has circulated online as a life hack for exactly this problem. It sounds ridiculous, but it rests on a simple idea.

Why Does a Can Opener Work on Plastic Packaging?

A can opener works because it is a tool specifically designed to bite into and smoothly cut through tough materials. It can slice through the thick plastic seams much like it slices through an aluminum can, leaving a surprisingly smooth edge.

How Do You Open Clamshell Packaging with a Can Opener?

Follow these steps:

• Grab a Manual Can Opener: You need the classic, manual style—the one with the two handles you squeeze together and a little knob you turn. An electric can opener won't work for this.
• Clamp the Edge: Take the sealed plastic clamshell package and clamp the can opener onto the very edge of the sealed seam, just like you would clamp it onto the lip of a soup can. Make sure the cutting wheel is positioned right over the thickest part of the plastic rim.
• Squeeze and Turn: Squeeze the handles tightly together to puncture the plastic, and begin turning the knob.
• Slice Around the Perimeter: The cutting wheel should travel along the edge of the packaging, cleanly slicing through the thick plastic seal. Just guide it around three sides of the package.
• Pop it Open: Once you've cut along the sides, the package can simply open up like a book. No jagged edges, no struggling, and far less risk of cut fingers.

Is the Can Opener Hack Worth Trying?

Yes, if you are tired of wrestling with impossible packaging and risking an injury just to get your new electronics out of the box. The can opener can glide through the plastic with little resistance. Keep a manual can opener handy—it is a simple weapon against the modern world's most annoying packaging!
