Writing on plastic can be challenging due to its non-absorbent nature. To ensure ink adhesion, it is advisable to prepare the plastic surface by oxidizing it with a light flame, being careful not to melt or discolour the plastic. Various permanent markers are suitable for writing on plastic, including the Shuttle Art permanent markers, which offer a large assortment of colours with pigmented, water and smear-resistant ink. The Uni Pin Pen, with its richly pigmented oil-based ink, is another excellent option for writing on multiple surfaces, including plastic. PHOSEA permanent markers are also versatile, with a fine point tip that enables smooth and precise writing on plastic and other materials. For those seeking a cost-effective option, the Pilot brand offers a similar oil-based pen with a larger range of tip sizes.

What You'll Learn
Use a multi-surface pen
Using a multi-surface pen is one of the simplest ways to write on plastic. These pens are designed to write on non-paper media and are used by artists, scientists, engineers, and parents alike. Multi-surface pens are also known as universal pens and are available in a variety of colours and tip sizes.
Universal pens are ideal for writing on plastic because they are smudge-proof and waterproof. They are also opaque, which means they will show up on dark and transparent surfaces. Their ink adheres well to plastic and dries quickly, reducing the risk of smudging. Before purchasing a universal pen, check that it is suitable for plastic by looking at the listed applications. For example, Staedtler's universal pen is marketed for use on plastic, glass, fabric, wood, stone, and more.
When using a universal pen to write on plastic, it is important to give the ink ample time to dry. Plastic is less absorbent than paper or canvas, so the ink will take longer to set. Avoid exposing the plastic to external impacts such as weather and pressure immediately after writing, as this can cause the ink to smear. Instead, wait a few seconds, then use a hairdryer or mild sunlight to ensure the writing dries and stays in place.
There are several highly-rated multi-surface pens on the market. The Zebra Onamae name marker is a good option, featuring both a fine and extra-fine tip for versatility. The Uni Pin Pen is another excellent choice, with richly pigmented oil-based ink that writes well on different surfaces. Once the ink sets, it won't rub off except with alcohol. For a pen with a wider range of tip sizes, consider the Pilot line of oil-based drawing pens.

Try oxidising the plastic surface
If you want to write on plastic paper, one method is to first oxidise the plastic surface. This process can help prepare the plastic surface to get the ink to stick.
Firstly, you should be aware that oxidation can lead to an unpleasant appearance on plastic surfaces and can cause the plastic to wear down and develop a rougher texture. It can also lead to the release of volatile organic compounds (VOCs) and dust from polished-off residue, which can cause eye irritation. Therefore, it is important to take precautions such as wearing protective gear and ensuring the area is well-ventilated when attempting to oxidise plastic.
To oxidise the plastic surface, you can pass the plastic past a small flame, such as a candle or a propane torch. Move the flame quickly back and forth so that the plastic does not melt or get discoloured. This process lightly "burns" the plastic, creating a surface that is more receptive to ink.
Once you have treated the plastic surface with the flame, you can begin writing on the area. Use a permanent marker and go over the area you flame-treated. The ink should now resist coming off.
If you notice any discolouration or fading on the plastic surface after flame treatment, you can attempt to restore the plastic by removing the oxidation. For example, you can use soapy water and sandpaper to gently rub the surface in a circular motion, covering each section multiple times. Alternatively, you can mix a solution of vinegar and water and apply it to the affected area with a spray bottle or sponge. For heavier oxidation, a cutting compound may be required.

Choose a pen with pigmented ink
When writing on plastic, it's important to use the right tools to ensure your writing stays put. One of the most important factors in choosing a pen for writing on plastic is the type of ink it contains. Opting for a pen with pigmented ink is a wise choice, as this type of ink is designed to adhere to a variety of surfaces, including plastic.
Pigmented ink is formulated to be versatile and adaptable, making it ideal for use on non-paper media. This type of ink is commonly found in multi-surface pens, which are popular among artists, scientists, engineers, and even parents who need to write on a variety of materials. The pigmented ink in these pens is often designed to be stable and quick-drying, ensuring that it doesn't smudge or smear easily.
One example of a pen with pigmented ink that works well on plastic is the Shuttle Art permanent marker. This marker produces pigmented ink that is both water and smear-resistant, making it ideal for writing on plastic surfaces. The ink is also formulated to dry quickly and last for a long time, ensuring that your writing stays put.
Another option is the Uni Pin Pen, which contains richly pigmented oil-based ink. This type of ink writes exceptionally well on different surfaces, including plastic. Once the ink sets, it won't rub off unless removed with alcohol. While it performs well on plastic, it truly excels on metal and is a favourite among artists for technical drawings and sketches.
When choosing a pen with pigmented ink, it's important to consider the specific type of plastic you'll be writing on. Some plastics, such as plastic cups or tumblers, may require a different approach than others. Additionally, it's worth noting that the preparation of the plastic surface can also impact the success of the ink adhesion. In some cases, lightly "burning" the plastic with a flame can help the ink stick better, but it requires careful execution to avoid melting or discolouration.

Opt for a pen with smudge-proof and waterproof ink
When writing on plastic, it's important to consider the type of pen you're using to ensure your writing stays put. Opting for a pen with smudge-proof and waterproof ink is a great way to ensure the longevity of your writing.
Permanent markers are a popular choice for writing on plastic, and for good reason. They are designed to have a stable ink flow and write on multiple surfaces, not just plastic. This means you can use them on a variety of materials with confidence. When choosing a permanent marker, look for one that is specifically marketed for use on plastic, like the Shuttle Art permanent markers. These markers are designed to be water and smear-resistant, so you can be confident that your writing will not fade or smudge easily.
Another option is to use a pen with richly pigmented oil-based ink, such as the Uni Pin Pen. Oil-based inks tend to have excellent adhesion to surfaces and are often smudge-proof and waterproof. The Uni Pin Pen, in particular, is known for writing exceptionally well on different surfaces, and once the ink sets, it won't rub off except with alcohol.
If you're looking for a more unique option, the PHOSEA permanent marker set offers an extra-fine point tip of 0.7mm, allowing for smooth lines and precise control. The acrylic-based ink dries quickly, producing a glossy finish without leaving unwanted odors. This pen is also non-toxic and safe for children, making it a versatile option for artists, students, and parents alike.
While permanent markers and oil-based pens are excellent choices, it's important to remember that the success of your writing also depends on the type of plastic you're using. Some plastics may require a light flame treatment, as mentioned earlier, to ensure the ink adheres properly. Always test your pen on a small area of the plastic first to ensure it performs as expected.
By choosing a pen with smudge-proof and waterproof ink, you can confidently write on plastic surfaces, knowing that your writing will withstand the test of time and won't be easily rubbed or washed away.
