Sublimation on corrugated plastic is a process that allows you to transfer vibrant designs onto plastic surfaces. Corrugated plastic is a lightweight, tough material made from polypropylene, featuring a fluted or wavy design between two thin plastic sheets. While corrugated plastic doesn't naturally absorb sublimation ink, a workaround exists: applying a polyester coating to the plastic surface. This process involves cleaning the plastic with alcohol, applying a polyester spray coating, printing your design on sublimation paper, and using a heat press to apply the design to the coated plastic. With the right preparation and materials, you can create beautiful sublimated plastic products with durable, vibrant designs.

Prepare the surface: Clean corrugated plastic with alcohol to ensure adhesion
To prepare the surface of corrugated plastic for sublimation, it is important to clean it with alcohol to ensure adhesion. This will remove any fingerprints, oils, dirt, or dust that may interfere with the printing process and the final product's quality.
Isopropyl alcohol, also known as isopropanol or rubbing alcohol, is commonly recommended for cleaning plastics effectively. It can be used to wipe down the corrugated plastic surface, ensuring no residue is left behind. It is crucial to note that you should not let the alcohol air dry, as it may accentuate problem areas. Instead, wipe the surface with a damp cloth and then immediately follow up with a dry microfiber cloth to ensure a streak-free finish.
When working with large corrugated plastic sheets, sectioning the cleaning process can be beneficial. Spray the alcohol onto one area, wipe it clean, and ensure it is thoroughly dry before moving on to the next section. This methodical approach ensures a consistent finish across the entire sheet.
Additionally, mixing a degreasing agent, such as orange dishwashing soap, with warm water in a spray bottle can be an effective alternative to alcohol. This mixture can help remove stubborn grease or oil stains and is safe for printed surfaces.
By following these steps and choosing the appropriate cleaning solution, you can adequately prepare the surface of corrugated plastic for sublimation, ensuring optimal adhesion and a high-quality final product.

Apply a polyester coating: Use a spray coating for non-porous surfaces
Sublimation on corrugated plastic can be achieved by applying a polyester coating using a spray coating designed for non-porous surfaces. This process involves several steps to ensure a successful and durable finish.
First, it is essential to prepare the corrugated plastic surface by cleaning it with a mild detergent and water solution to remove any dirt, grease, or residue. The surface should then be dried thoroughly to ensure no water interference with the coating.
Next, you need to select the appropriate spray coating. Ensure you choose a polyester coating specifically designed for use on non-porous surfaces, as these coatings are formulated to adhere properly to smooth, non-absorbent materials. Read and follow the manufacturer's instructions for the chosen product, as application techniques may vary slightly between brands.
When applying the polyester coating, ensure you are in a well-ventilated area and wear the appropriate personal protective equipment, including a respirator, eye protection, and gloves. Hold the spray can or gun approximately 10-12 inches away from the surface and spray in steady, even strokes, overlapping each pass slightly to ensure complete coverage. Apply multiple thin coats, allowing adequate drying time between each coat as per the manufacturer's recommendations.
Once you have applied the final coat, allow the coating to cure completely. The curing time will vary depending on the product used and the environmental conditions, such as temperature and humidity. Refer to the manufacturer's guidelines for specific curing times.
After the coating has cured, you can proceed with the sublimation process. Follow the standard sublimation instructions for the specific substrate you are using. This typically involves creating your design, printing it onto sublimation transfer paper, and then applying heat and pressure to transfer the design onto the coated corrugated plastic. Ensure you follow the recommended time, temperature, and pressure settings for optimal results.

Print your design: Print your design on sublimation paper with sublimation ink
To print your design, you will need a sublimation printer with sublimation ink installed. You can use brands such as Hiipoo, Printers Jack Ink, Sawgrass, or Epson. Angie Holden from The Country Chic Cottage recommends turning off the high-speed setting and turning on the best quality printing setting to get more vibrant colours. She also suggests using a matte paper setting.
You will also need special sublimation transfer paper. TruePix (for Sawgrass) and A-Sub (for Epson) are two examples of sublimation paper that you can use.
Before printing, you will need to resize your image to print it correctly. There are free and paid programs available online that you can use to resize your image and make your print the exact size you need. Be sure to double-check the size of your image before printing.
After printing your design, you will need to use high temperatures and pressure to transfer the ink permanently to your corrugated plastic.

Use heat-resistant tape: Secure the sublimation paper in place with heat-resistant tape
Sublimation projects require heat-resistant tape to secure the sublimation paper in place. This tape is essential to prevent ghosting and avoid the adhesive from melting onto the surface. It is important to select a suitable tape for your project, as not all heat-resistant tapes are the same. Some tapes are designed for lower temperatures, and using them at higher temperatures can cause them to leave yellow marks on your project.
To ensure the best results, it is recommended to test the tape on a small, inconspicuous area first. This will allow you to check for any potential issues, such as poor adhesion or residue transfer. High-quality heat-resistant tape should be used to prevent these issues, as poor-quality tape is more likely to leave residue or discolour your project. Additionally, some tapes are designed for specific surfaces, such as mugs or fabrics, so choosing the right tape for your project is crucial.
There are various types of heat-resistant tape available, including polyester or polyimide tapes, which are effective options that don't melt or leave residue. Cricut also offers blue heat-resistant tape that fits regular tape dispensers, and clear heat-resistant tape is available from other suppliers. It is important to note that some tapes are less sticky, so magnetic clamps or silicone strips can be used alongside the tape to secure the sublimation paper, especially when working with cylindrical items.
When using heat-resistant tape, it is essential to consider the type of surface you are working on and the temperature required for your project. By selecting the appropriate tape and using it correctly, you can effectively secure the sublimation paper in place and achieve accurate design transfers without any residue or discolouration.
