Why is There a Crease in the Edge Banding After It Is Applied?73

As a leading Chinese manufacturer of edge banding for furniture, we often encounter inquiries from customers regarding creases or wrinkles in the edge banding after it has been applied. In this article, we will explore the possible reasons behind this issue and provide solutions to prevent it from occurring.

Causes of Creases in Edge Banding

1. Improper Bonding Temperature: The temperature used for bonding the edge banding to the substrate is crucial. If the temperature is too low, the adhesive will not properly bond, resulting in a weak hold that can cause creases or wrinkles. Conversely, if the temperature is too high, the adhesive can become overheated and brittle, leading to similar issues.

2. Insufficient Pressure: Adequate pressure must be applied to ensure a secure bond between the edge banding and the substrate. If insufficient pressure is applied, the adhesive may not fully spread, creating gaps or weak areas that can result in creases.

3. Poor Edge Preparation: Before applying edge banding, the edge of the substrate must be clean, dry, and free of any imperfections. If the edge is not properly prepared, the adhesive may not adhere correctly, leading to creases or delamination.

4. Excessive Bending: Edge banding materials have a specific bending radius that should not be exceeded during installation. If the edge banding is bent too sharply or excessively, it can create creases or wrinkles.

5. Material Shrinkage: Certain types of edge banding materials, such as PVC or melamine, can shrink slightly after application. If the material shrinks excessively, it can cause creases or wrinkles in the edge banding.

Preventing Creases in Edge Banding

To prevent creases from forming in edge banding, several best practices should be followed:
Use the correct bonding temperature recommended by the adhesive manufacturer.
Apply sufficient pressure during bonding to ensure a strong hold.
Properly prepare the edge of the substrate before applying edge banding.
Avoid bending edge banding beyond its recommended bending radius.
Select edge banding materials that have minimal shrinkage properties.
If creases or wrinkles do occur, they can be repaired by carefully applying heat from a heat gun or iron and pressing the edge banding flat.

Conclusion

Creases or wrinkles in edge banding can be caused by various factors, including improper bonding temperature, insufficient pressure, poor edge preparation, excessive bending, and material shrinkage. By following the best practices outlined above, these issues can be prevented, ensuring a smooth and flawless finish for your furniture edge banding applications.
