Understanding Black Dots in Lunchbox Binding Strips389

As a leading manufacturer of edge banding strips for furniture in China, we understand the importance of high-quality products. Recently, we have noticed an increase in inquiries regarding black dots appearing on our lunchbox binding strips. To provide clarity on this matter, we have prepared this detailed explanation.

Causes of Black Dots

Black dots on lunchbox binding strips are generally caused by carbonized contaminants. These contaminants can originate from various sources during the manufacturing process, including:* Foreign materials: Small pieces of metal, plastic, or other foreign materials can become embedded in the binding strip during production.
* Mold release agents: These chemicals are used to prevent the binding strip from sticking to the mold during molding. If not properly removed, they can leave behind black residue.
* Process residues: Carbon particles from the manufacturing equipment or environment can also accumulate on the binding strip, causing black dots.

Effect of Black Dots

The presence of black dots on the binding strips does not necessarily affect their performance. However, it can impact the aesthetic appeal of the lunchboxes, especially for high-end or premium products. In some cases, the black dots may be noticeable on the finished surface of the lunchbox.
