How to Open Rigid Plastic Clamshell Packages Safely
Those oversized, rigid 'clamshell' packages may help to secure items for shipping and cut down on shoplifting, but they can be a nightmare for consumers. There's even a term for the frustration they inspire: wrap rage.[1]

In 2004, over 6,000 Americans went to the emergency room with injuries resulting from opening difficult packaging! Here's a rundown on how to preserve your hands and sanity when confronting a blister pack that has no apparent means of entry.
Steps

Can Opener Method

Get a manual rotary can opener.

Open the clamshell as if it were a can. The sharp wheels of the can opener will cut the plastic without cutting your hands. It won't go around the corners, so just cut open one side. This will give you plenty of room to...

Insert a knife between the two layers of plastic and cut all the way around. Since the blade is inside the package and pointing towards the center, it's much safer than trying to stab through the plastic and wedge the tip in between. With a decent knife, the remainder of the plastic should be easy to cut.

Knife, Box Cutter or Scissors Method

Recognize the dangers of using these sharp implements. People do cut themselves frequently, as mentioned in the introduction.

Cut carefully all the way around the edge with the best scissors or box cutters that you can get your hands on, until the package easily opens. Do NOT cut across the middle of the package; you could cut through the instructions or a part of the product, and it's the most cumbersome way to go. Start on the right side of the package, cutting up and around the perimeter, if you are right-handed. If you are left handed, start on the left. Be willing to quickly admit it if your favorite scissors or knife aren't sharp enough to allow you to cut smoothly and safely. Your uncut hands will thank you later. Borrow or buy a can opener.

What's your reaction?
