Why Does My Edge Banding Show White After Folding?44

As a Chinese furniture edge banding factory, we have encountered the issue of edge banding showing white after folding on numerous occasions. This can be a frustrating problem for manufacturers and consumers alike, as it can ruin the appearance of an otherwise beautiful piece of furniture. In this article, we will discuss the causes of this problem and provide solutions to prevent it from happening in the future.

Causes of White Edge Banding After FoldingThere are several factors that can contribute to edge banding showing white after folding. The most common causes include:
Insufficient adhesive: When there is not enough adhesive applied to the edge banding, it can cause the banding to separate from the substrate when folded. This will result in a white gap between the banding and the substrate.
Improper adhesive application: The adhesive must be applied evenly to the entire surface of the edge banding. If it is not, it can cause weak spots in the bond, which can lead to the banding separating from the substrate when folded.
Substrate not properly prepared: The substrate must be clean and free of any dirt or debris before the edge banding is applied. If the substrate is not properly prepared, the adhesive will not bond properly and the banding may separate from the substrate when folded.
Incorrect folding technique: The edge banding must be folded at the correct temperature and speed. If it is folded too quickly or at too high a temperature, it can cause the adhesive to melt and the banding to separate from the substrate.

Solutions to Prevent White Edge Banding After FoldingThere are several things that can be done to prevent edge banding from showing white after folding. These include:
Use a high-quality adhesive: The adhesive used to bond the edge banding to the substrate must be able to withstand the stresses of folding. We recommend using a hot melt adhesive that is specifically designed for edge banding applications.
Apply the adhesive evenly: The adhesive must be applied evenly to the entire surface of the edge banding. This can be done using a roller or a brush.
Properly prepare the substrate: The substrate must be clean and free of any dirt or debris before the edge banding is applied. This can be done by sanding the substrate or using a solvent to clean it.
Use the correct folding technique: The edge banding must be folded at the correct temperature and speed. The temperature of the substrate should be between 60°C and 80°C (140°F and 176°F). The folding speed should be between 10 and 15 meters per minute (33 and 50 feet per minute).

ConclusionBy following these tips, you can prevent edge banding from showing white after folding. This will result in a more beautiful and durable piece of furniture that will last for years to come.
