PU heat transfer stickers

01 Applications

PU heat transfer stickers are a type of graphic transfer used to apply designs onto fabrics, especially in the garment and textile industry. They are made from a polyurethane-based material that becomes adhesive when heated, allowing the sticker to transfer its design onto clothing or other fabric surfaces. These stickers are known for their flexibility, durability, and vibrant colors, making them a popular choice for custom t-shirts, hoodies, sportswear, and other fabric-based items.

02 Preparation

Ensure the fabric is clean, dry, and free of wrinkles. Pre-press the fabric for a few seconds to remove moisture.

Position the heat transfer sticker on the fabric where you want the design to appear. Secure it with heat-resistant tape if necessary.

Set your heat press to the recommended temperature, pressure, and time specified by the manufacturer of the transfer sticker. For home irons, use a high-temperature setting without steam.

Apply heat and pressure according to the specified duration. Once the transfer is complete, allow it to cool for a few seconds to a minute before removing the backing.

Carefully peel off the backing paper from the transfer. If the design has fully adhered, it’s ready. If not, reapply heat and pressure as needed.

Let the garment cool completely, and avoid washing for at least 24-48 hours to ensure the design sets properly.

03 FAQ

Q1:What should I do if my sticker doesn’t adhere properly?

If the sticker doesn’t adhere, try reapplying heat and pressure. Check for even pressure, and ensure the temperature and time settings are correct. If the problem persists, consider replacing the sticker or contacting the manufacturer for guidance.

Q2:What temperature and time should I use for heat pressing?

The recommended temperature and time vary depending on the sticker’s specifications. Generally, temperatures range from 300 to 350°F (150 to 180°C), and the time is typically 10 to 20 seconds. Refer to the specific instructions from the sticker’s manufacturer.

Q3:How durable are PU heat transfer stickers?
