Keeping permanent marker on plastic can be challenging due to the smooth and shiny surface of the material. This is a common issue for teachers who need to label plastic items in the classroom, as well as for those looking to personalize their plastic belongings. While permanent markers are designed to be long-lasting, they can often be wiped off plastic surfaces with ease. To address this problem, various methods can be employed, ranging from using alternative writing instruments to applying protective coatings. These techniques ensure that the marker stays on the plastic surface and do not smear or rub off.

What You'll Learn
Use dot stickers and write on the dots
Using dot stickers is a great, inexpensive way to label plastic items. These colourful dots can be stuck onto plastic items, and then you can write on them. This method is perfect for labelling tiny items like classroom manipulatives.
Firstly, ensure that the plastic surface is clean and dry. You can use soap and water, or alcohol, to wipe down the plastic surface. You may also need to use something acidic to remove any stubborn marks or stains. It is important to get rid of any grease, as this will cause your marker to wipe off easily. Once the surface is clean, run your hand over it to check for any remaining oil spots.
Next, apply the dot stickers to the plastic surface. These stickers are usually paper-fronted with a strong adhesive backing. Place them in the desired location, pressing down firmly to ensure they are securely attached.
Now, you can write on the dots with a permanent marker. Choose a good brand of permanent marker, preferably a new one, as older markers may not work as effectively. Write clearly and carefully on each dot, ensuring the ink is dry before moving on to the next dot to avoid smudging.
Finally, you can add an extra layer of protection by covering the dots with clear tape, such as clear packing tape. This will help seal in the ink and protect it from smearing or rubbing off. Run your finger around the edges of the tape to ensure a good seal. With this method, your labels should last for a while before the adhesive starts to dry out and turn yellow.

Apply a plastic adhesive sheet
To preserve marker ink on plastic, one method is to apply a plastic adhesive sheet. This method is especially useful for plastic surfaces that are handled often, such as a plastic game case.
First, ensure that the plastic adhesive sheet is compatible with the plastic surface. Select a plastic adhesive sheet that is designed to adhere to plastic materials. Check the product specifications or consult with a specialist to confirm compatibility.
Next, cut the plastic adhesive sheet to size. Measure the dimensions of the plastic surface and cut the sheet accordingly. It is important to be precise in your measurements to ensure a snug fit.
Before applying the adhesive sheet, prepare the plastic surface. Clean the area with a suitable solvent, such as isopropyl alcohol, to remove any dirt, oils, or residues that may interfere with adhesion. Ensure the surface is completely dry before proceeding.
Now, carefully align the adhesive sheet with the plastic surface, following any instructions provided by the manufacturer. Smooth out any air bubbles using a flat tool, such as a credit card, working from the centre towards the edges to ensure a tight bond.
Finally, trim any excess material from the edges of the plastic using a sharp blade or scissors. This will give a neat finish and ensure the adhesive sheet is secure.
By following these steps, you can effectively apply a plastic adhesive sheet to protect marker ink on plastic surfaces.

Cover with clear packing tape
If you want to keep marker ink on a plastic surface, one option is to cover it with clear packing tape. This method can also be used to protect writing on paper.
First, clean the plastic surface with isopropyl alcohol to prep the area. Then, apply the clear packing tape over the marker ink, ensuring that it covers the area entirely. Run your finger around the edges of the tape to seal it and prevent the tape from peeling.
While this method is effective, it is important to note that the adhesive on the tape will eventually dry out and turn yellow, which may impact the appearance of your project. This process typically takes about six months.
Before applying the tape, it is recommended to test the tape on a different surface to ensure that it does not react with the plastic or marker ink.

Write with black nail polish
To write with black nail polish on plastic, you can follow these steps:
Firstly, it is important to note that you should always test any method on a small area first to ensure it does not react with the plastic or marker. One way to keep your writing on plastic is to use a plastic adhesive sheet cut to fit the object. Ensure you do not spray anything on the sheet that might dissolve the marker with its solvents.
If you want to use black nail polish specifically, you can make your own by mixing two colours together, such as green and yellow, or blue and red, to create black. You can also add clear nail polish to the mixture. Pour a small amount of the nail polish into a plastic cup and use a nail polish brush or a toothpick to mix the colours. Adjust the colour by adding more of the shades as needed.
Once you have your desired black shade, you can write on the plastic with the nail polish. You could also use a dry erase marker to write over the plastic, and then wipe it away, sealing the permanent marker beneath.
To protect your writing, you could use clear packing tape over the surface. Ensure you prepare the area with isopropyl alcohol before applying any tape.

Use an engraver pen
Using an engraver pen on plastic is a great way to permanently mark plastic items. Engraving is a fun way to personalize and customize generic items, and it can be an enjoyable project for anyone who likes to be hands-on.
There are a variety of engraving tools available, including electric micro-engraver pens, which are lightweight, portable, and easy to control. They are also versatile and can be used on materials such as metal, glass, ceramic, plastic, and wood. Before purchasing an engraving tool, it is important to ensure that it is suitable for use on plastic.
When using an engraver pen, it is important to apply enough pressure to make a mark on the plastic. However, unlike harder materials such as metal, plastic does not require too much pressure. Practicing on a separate piece of plastic beforehand can help you get a feel for the right amount of pressure needed. It is also a good idea to print out a paper template to guide your work, especially if you are creating intricate designs or etching words.
Before starting your project, ensure that the plastic surface is thoroughly cleaned. Depending on the type of plastic, you may be able to clean it with soap and water, or you may need to use specialized cleaning products. Additionally, make sure that the plastic is securely held in place to prevent it from moving during the engraving process.
Engraving on plastic can be a fun and rewarding experience, allowing you to add a unique and permanent touch to your belongings.
