Several key points affecting the quality of PVC edge banding

There are many factors that affect the quality of edge banding, but these aspects are particularly important. Firstly, the substrate. 2, Radiance and size. 3, Printing. 4, Adhesive backing. Below, the editor will provide you with a detailed introduction.
1, Base material for PVC edge banding
In the production process of edge banding, the substrate is the carrier and foundation of the edge banding. We call it PVC edge banding for products processed from PVC powder, ABS edge banding for products processed from ABS substrate, and so on. The substrate is also the property, so having a good substrate is very important. The edge banding starts from selecting the substrate, and the edge banding uses PVC powder granulation imported from Germany. At the beginning of granulation, the problem of edge color matching in the later stage is considered, and color matching is carried out together with edge printing, which effectively solves the problem of uniform edge cutting and bottom surface.
2, The curvature of the clone of the edge banding strip
When bonding and squeezing the edge banding, a good edge banding should have a certain degree of inward bending in its width direction, while a poor edge banding is flat, and some may even tilt back, making it difficult to bond.
3, Printing of PVC
There are two processes for printing PVC surface colors: printing and heat transfer film. Heat transfer film products are relatively smooth, but due to their high cost, slow transfer speed, and inability to match colors well with the board, they have been replaced by printing. However, some inferior PVC edge banding strips have a high content of calcium carbonate, which may cause color fading if printed. Since 2016, more advanced water-based ink printing technology has been adopted, which has made the printing effect of edge banding surpass that of domestic edge banding manufacturers.
4, Adhesive backing for PVC edge banding
The quality of the backing adhesive directly affects the bonding effect. The backing adhesive is not actually a glue, but a bridging agent that acts as a bridge in the middle. Especially in cold weather, due to the low temperature in some furniture factories' workshops, the efficiency of hot melt adhesive and backing adhesive is greatly reduced, and these furniture factories often attribute the responsibility to the quality of the edge banding, which is unreasonable.
