Heat-Shrinkable Foil and Sublimation: A Perfect Match!

Sublimation is a popular technique for printing images and designs on various materials. An interesting addition to this technique is the use of heat-shrinkable foil. When combined with an oven, shrink foil can elevate the sublimation process, resulting in vibrant and durable creations. In this blog, you'll discover everything you need to know about using shrink wrap in sublimation.

What is Heat-Shrinkable Foil?

Shrink foil, also known as shrink tubing, is a plastic sheet that shrinks when heated. This process ensures that the film tightens around the substrate, applying pressure similar to the use of a mug press or a wrap, resulting in a smooth and personalized surface.

Benefits of Shrink Foil with Sublimation

Sublimating cylindrical products, such as mugs, water bottles, cups, glasses, as well as (flower) pots and bowls, can be challenging due to their complex shapes. However, using shrink foil in conjunction with an oven can significantly simplify and enhance the process.

• Even heat distribution: An oven provides uniform heat distribution around the product, essential in sublimation where heat and pressure must be applied evenly to achieve a high-quality print. By covering the product with shrink foil and placing it in the oven, heat is evenly distributed over the entire surface, resulting in a consistent and vibrant print.
• Uniform shrinkage: In an oven, shrink foil can shrink evenly and controlled. This is crucial to ensure that the shrink foil tightens around the sublimation design, creating a smooth surface without air bubbles or wrinkles. Uniform shrinkage contributes to a professional result.
• Efficiency and scalability: Using an oven with shrink foil allows for sublimating multiple products at the same time, increasing efficiency, and making the process scalable for larger production quantities. It saves time and energy, especially when working with large quantities of products.
• Material flexibility: With an oven, you can sublimate various materials such as ceramics, glass, and metals. By using shrink foil, you can protect these materials and guarantee a durable, high-quality finish, regardless of the substrate material.

How to use Heat-Shrinkable Foil with Sublimation?

• Prepare the substrate you want to print on: Ensure that the substrate is clean and free of grease before starting sublimation.
• Design your sublimation print: Create an attractive design that you want to sublimate onto the substrate.
• Print and press: Print the design using a sublimation printer with sublimation ink and paper.
• Cut and attach the shrink foil: Use the appropriate size of shrink wrap and ensure it fully covers the sublimation design. Place the shrink foil over the sublimation design.
• Heat and shrink: Heat the entire setup with a heat gun or place the object in the oven until the shrink foil tightly encases the sublimation design.
• Cool and admire: Let the setup cool, peel off the shrink foil from the product, and admire the beautiful, professional result!

Tips for successful Sublimation with Heat-Shrinkable Foil

• Experiment with temperatures and times: Different heat-shrinking foils and types may require different temperatures and times for the best result. Experiment and adjust until you find the perfect process.
• Be patient: Take the time to heat the shrink foil evenly. Heating too quickly or too slowly can lead to unwanted results.
• Practice makes perfect: It may take some time to master the technique. Keep practicing and don't be afraid to experiment with different designs and films.

With heat-shrinkable foil, you can elevate your sublimation projects to a higher level. The combination of sublimation and heat-shrinkable foil offers not only durability and protection but also endless creative possibilities. So, what are you waiting for? Get started and create beautiful, personalized items using this fantastic technique!
