Rigid plastic packaging, often called clamshell packaging, is notoriously difficult to open. The process of opening such packages has been dubbed wrap rage, and it's not uncommon for people to injure themselves in the process. The best way to avoid this is to buy products in plastic packaging that is designed to be easier to open, with pull tabs or perforated lines. If you can't avoid hard plastic casing, there are several tools you can use to open it, such as tin snips, a rotary can opener, a knife, or scissors. It's important to take precautions when using sharp objects to open plastic packaging, such as wearing protective gloves and cutting away from your body.

What You'll Learn
Wear protective gloves and move away from others
When attempting to open a hard plastic case, it is important to take safety precautions to avoid injury. Protective gloves should be worn to shield your hands from potential hazards. The specific type of glove will depend on the nature of the contents within the plastic case. If you are dealing with hazardous materials, chemicals, hot or cold liquids, rough or sharp-edged objects, or items that pose a risk of thermal burns, you should opt for gloves suitable for those conditions. For instance, leather (Nomex and thick knit cotton) gloves are ideal for protection against hot surfaces. Neoprene gloves are suitable for protection against common oils, aliphatic hydrocarbons, and certain solvents, but they are not effective against aromatic hydrocarbons, halogenated hydrocarbons, ketones, and many other solvents. Nitrile gloves are a good option for protection from incidental splashes or contact with lab chemicals, but it is important to consult the Safety Data Sheet (SDS) to ensure compatibility. Glove length is also a factor to consider, with longer gloves providing extra protection against splashes or immersion. Additionally, ensure the gloves fit properly—too tight and they can cause fatigue, while too loose and they may hinder your work.
Before donning the gloves, inspect them for any signs of degradation or puncture. To test for pinholes, blow or trap air inside the gloves and roll them out. Avoid filling them with water as this may make it difficult to detect leaks. Once you have the right gloves in place, move away from others to ensure their safety. If anyone is within close proximity and at risk of injury, it is advisable to maintain a safe distance. This precaution is particularly important if you are using sharp objects like knives or scissors during the opening process.
By following these safety measures, you can effectively protect yourself and those around you from potential harm when opening hard plastic cases. It is important to be cautious and prepared, especially when dealing with hazardous or sharp objects.

Avoid using knives or scissors
It is best to avoid using knives or scissors to open hard plastic cases. Knives and scissors are dangerous and can cause injury. If you do decide to use a knife, remember to cut away from your body and to wear protective gloves. You should also ensure that no one is close enough to be injured. Additionally, if you use scissors, opt for a pair with blunt tips.
Instead of knives or scissors, you can use tin snips or aviation snips, which are designed for cutting thin metal but also work on rigid plastic. These tools provide extra leverage, and their blades are not too sharp, reducing the risk of injury. Alternatively, a rotary can opener or a pair of safety blades, such as Slice micro-ceramic-blade knives or Slice pen cutters, can be used. These safety blades feature a patent-pending grind that is safe to the touch and can easily cut through rigid plastic.
If you want to avoid using any sharp tools altogether, look for plastic packaging that has pull tabs or perforated lines. This type of packaging can be opened by simply pulling on both parts or pushing along the perforated lines. Additionally, some products offer "Frustration-Free Packaging," which is easier to open and recyclable.

Use a rotary can opener or tin snips
When dealing with hard plastic cases, it is advisable to wear protective gloves and ensure that no one is close enough to be accidentally injured. If you have to use sharp objects, remember to cut away from your body.
If you have tin snips in your toolbox, they can be very effective in cutting through hard plastic. Tin snips cut effortlessly through the plastic and pose less risk of injury compared to knives or scissors.
Alternatively, a rotary can opener can be used to open hard plastic cases. Insert the bottom edge of the package inside the rotary can opener, just as you would when opening a can. Then, turn the can opener until you reach the other end of the package. You may then be able to remove the item from the package without further effort.
Both tin snips and rotary can openers are useful tools for opening hard plastic cases. They are safer than knives or scissors and can often do the job more efficiently.

Look for pull tabs or perforated lines
If you are struggling to open a hard plastic case, the first thing to do is to check for pull tabs or perforated lines. These are usually found on plastic packaging that is designed to be easier to open.
Pull tabs are small, often downward-hanging, tabs that you can use to slowly peel back the plastic packaging. However, these can sometimes be poorly designed, making them difficult to use. For example, the pull tab may not come off cleanly, leaving remnants of the seal stuck to the rim. Or, the plastic may be twisted, making it separate from the paper when you pull, which can make it hard to open. To combat this, try rubbing your finger around the outside edge of the adhesive to warm it up and then pull. You can also use the bottom of a hot coffee cup to warm up the adhesive.
Perforated lines, on the other hand, indicate where you can cut or tear the plastic packaging. These lines are designed to make it easier to open the package without the need for sharp tools.
Overall, checking for pull tabs or perforated lines is a safer way to open hard plastic cases without the risk of injury.
