Is It Normal for Edge Banding to Appear White After Sealing?236

As a leading manufacturer of edge banding for the Chinese furniture industry, we often receive inquiries about the appearance of white lines or streaks along the edges of furniture after sealing. This phenomenon is commonly known as "edge banding泛白" in Chinese and can be a source of concern for manufacturers and consumers alike.

To understand this issue, it is important to know that most edge banding materials are made from a combination of wood fibers and adhesive. When the edge banding is applied to the furniture panel and heated during the sealing process, the adhesive melts and bonds to both the panel and the edge banding. However, if the adhesive is not evenly distributed or if the pressure and temperature during sealing are not controlled properly, air pockets can form between the edge banding and the panel.

These air pockets appear as white lines or streaks because they scatter light differently than the surrounding material. The phenomenon is more noticeable on darker or glossy finishes, which tend to accentuate any imperfections.

While some degree of泛白 is common and generally considered acceptable, excessive泛白 can detract from the overall appearance of the furniture. To minimize泛白, manufacturers can take the following steps:* Use high-quality edge banding materials: Edge banding with a uniform thickness and consistent adhesive distribution will reduce the risk of air pockets forming.
* Control the sealing process: The pressure, temperature, and time during sealing should be carefully controlled to ensure proper bonding and minimize air pockets.
* Inspect the edge banding after sealing: Inspecting the edge banding for any signs of泛白 and addressing any issues promptly is crucial for maintaining quality control.

In most cases,泛白 can be minimized by following these recommendations. However, it is important to note that certain factors, such as the type of furniture panel, the finish used, and the environmental conditions, can also influence the appearance of泛白.

If you are experiencing significant泛白 issues with your edge banding, we recommend consulting with a professional to identify and address the root cause.

Additional Tips for Preventing Edge Banding泛白* Use a primer before sealing: Applying a primer to the edge banding can help fill in any small gaps or imperfections, reducing the risk of air pockets forming.
* Apply the edge banding carefully: Ensure that the edge banding is properly aligned and firmly attached to the panel before sealing.
* Use a roller or press to apply pressure during sealing: This will help distribute the adhesive evenly and minimize air pockets.
* Allow the edge banding to cool completely before handling it: Allowing the adhesive to cool and cure properly will prevent the edge banding from shifting or detaching.
* Store the edge banding in a cool, dry place: Excessive moisture or heat can affect the adhesive's properties and increase the risk of泛白.
