To ensure that PVC banner hemming tape sticks smoothly and wrinkle-free on a PVC flex banner, it's important to follow a careful and precise process. Proper application of hemming tape can result in a clean, professional finish. Here are steps to achieve smooth and wrinkle-free hemming with PVC banner hemming tape:

Materials You'll Need:

- PVC flex banner

- PVC banner hemming tape

- Ruler or measuring tape

- Scissors or a cutting tool

- Heat source (heat gun or welding machine, if applicable)

- Roller or squeegee

- Clean, dust-free work surface

Steps:

1. Measure and Cut the Hemming Tape:

   - Measure the length of the banner edge that you intend to hem, and cut the PVC banner hemming tape to match the measured length. Ensure that the hemming tape is slightly shorter than the banner edge to prevent excess tape from extending beyond the banner.

2. Prepare the Banner Edge:

   - Clean the banner edge thoroughly to remove any dust, dirt, or contaminants that may interfere with adhesion. Ensure that the surface is dry.

3. Position the Hemming Tape:

   - Place the cut hemming tape along the edge of the banner, ensuring that it aligns with the edge evenly. Position the tape so that it extends slightly beyond the banner's edge, providing complete coverage.

4. Secure the Hemming Tape:

   - Press down firmly along the entire length of the hemming tape to ensure it adheres securely to the banner. Use a roller or squeegee to apply even pressure and remove any air bubbles or wrinkles as you go.

5. Heat Welding (If Applicable):

   - If you are using heat welding as part of the hemming process, carefully heat the banner edge and the hemming tape using a heat gun or welding machine. Follow the manufacturer's instructions for the specific heat welding equipment you are using. This process fuses the banner material and hemming tape together.

6. Trim Excess Tape (If Necessary):

   - If there is any excess hemming tape extending beyond the banner's edge, trim it carefully with scissors or a cutting tool to create a clean and neat finish.

7. Final Inspection:

   - Inspect the hemmed edge to ensure it is smooth, even, and free of wrinkles or bubbles. If any imperfections are present, make adjustments as needed.

8. Allow Adequate Bonding Time:

   - Some hemming tapes require time to fully bond with the banner material. Follow the manufacturer's recommendations for the required bonding time, which typically ranges from a few hours to 24 hours or more.

Properly applying PVC banner hemming tape and, if applicable, heat welding, requires precision and attention to detail. By carefully following these steps and using the right tools and materials, you can achieve a smooth and wrinkle-free hem on your PVC flex banner, ensuring a professional and long-lasting result.
