What You'll Learn

Using a manual can opener
If you are struggling to open a hard plastic package, one method you can use is a manual can opener. Before you start, check the back of the package for an opening. Some manufacturers include slits, perforations, and other starting points for opening their packages on the back or sides.
To use a manual can opener to open the package, insert the bottom edge of the package inside the can opener, as you would with a can, and turn the can opener until you reach the other end of the package. 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.
If you are still unable to open the package, you can repeat the can-opener process with the remaining edges of the package.

Scissors or box cutters
When using scissors or box cutters, it is important to exercise caution to avoid injury. Hard plastic packaging can be challenging to open, and it is easy to lose patience or become distracted, increasing the risk of accidental cuts. It is recommended to stay focused on the task at hand and be willing to admit defeat if your scissors are not sharp enough to cut smoothly and safely.
To use scissors or box cutters effectively, start by checking the back and sides of the package for any slits, perforations, or pop-together tabs that can be used as a starting point. Then, if using scissors, cut on all four sides of the package if necessary. If you are right-handed, start cutting from the right side, and if you are left-handed, start from the left. Avoid cutting across the middle of the package, as you may damage the product or instructions inside.
Box cutters, also known as safety cutters, are another effective tool for opening hard plastic packaging. They are designed with safety in mind and feature micro-ceramic blades that are safe to the touch. These blades are extremely hard and long-lasting, capable of cutting through rigid plastic while staying sharp. Some box cutters are even safe enough to take with you in your carry-on bag when travelling.

Aviation snips
When using aviation snips to open hard plastic packaging, it is important to take the necessary precautions to ensure your safety. Put on a pair of protective gloves before you begin, and make sure anyone standing nearby is at a safe distance. Always cut away from your body, and pay close attention to the position of the blade at all times.
To start, work your way around the outer edge of the packaging with the aviation snips. Cut through the plastic layers until you have freed enough of the material to peel it open. You can also try to pop open the middle once you have cut through the outer edge. This method is effective and safe, and it will not leave you with any sharp plastic edges or injuries.
If you do not have aviation snips, there are other tools you can use to open hard plastic packaging. A manual can opener, for example, can be used to cut through the plastic in a similar way as opening a can. You can also use a utility knife or scissors, but be cautious as these tools can leave sharp edges and increase the risk of injury.

Utility knife
Using a utility knife is an effective way to open hard plastic packaging, but it can be dangerous if you're not careful. Here are some detailed instructions on how to use a utility knife to open hard plastic packaging:
First, make sure you have a suitable utility knife for the job. A utility knife, also known as a box cutter, is a small, handheld tool with a sharp blade that can easily cut through hard plastic. Ensure the blade is sharp and made of a durable material like steel or ceramic. Ceramic blades, such as the Slice micro-ceramic-blade knives, can last much longer than metal blades and are safer to use.
Once you have your utility knife, follow these steps:
- Inspect the packaging: Before you start cutting, carefully inspect the packaging for any slits, perforations, or pop-together tabs that might serve as starting points. Some manufacturers include these features in response to consumer complaints about hard-to-open packaging.
- Prepare your workspace: Clear a flat, stable surface to work on and ensure you have good lighting. Hard plastic packaging can be challenging to open, so it's important to take your time and focus on the task at hand to avoid accidents.
- Insert the blade: Hold the utility knife in your dominant hand and carefully insert the blade into the edge of the packaging. If your packaging has a seam, this is usually the best place to start.
- Cut along the edges: With the blade inserted, slowly and carefully cut along the edges of the packaging. Apply gentle pressure and follow the contours of the package until you've cut through all sides. Be mindful not to cut across the middle, as you might damage the product or instructions inside.
- Open the packaging: After you've cut along all edges, the packaging should be fully opened. If needed, use your hands to gently pull apart the packaging to access the product inside.
- Dispose of plastic pieces: Once you've removed the product, remember to dispose of or recycle the plastic pieces safely. Hard plastic can be sharp, so be cautious when handling the cut edges.
Using a utility knife can be an effective way to open hard plastic packaging, but it's important to prioritize safety. Always cut away from your body, use slow and controlled movements, and store the utility knife responsibly when you're finished.
