Edge banding is a key process in the production of panel furniture. It is mainly achieved by seamlessly bonding the edge banding strips to the panel using edge banding adhesive. 
High-quality edge banding can bring multiple advantages to furniture: first, it can improve the appearance and texture of furniture, making the surface more beautiful and smooth; second, edge banding can effectively strengthen the panel structure and enhance moisture resistance, thereby significantly extending the service life of furniture; more importantly, high-quality edge banding can also block the release of formaldehyde inside the panel, adding a healthy guarantee to the home environment.

Edge banding glue plays an extremely important role in the edge banding process. Even if the board and edge banding are good, if the later bonding is not done properly, the quality of the furniture will be greatly reduced.
There are two common types of edge banding: EVA edge banding and PUR edge banding. The following are their characteristics and differences:
EVA edge banding is also called hot melt adhesive edge banding. It is a solid granular hot melt adhesive that is melted at high temperatures. The hot melt adhesive is evenly applied to the cross-section of the panel through an edge banding machine, and then the edge banding strips are extruded and bonded to complete the edge banding process.

This type of edge banding is the mainstream cabinet edge banding method on the market. Almost 90% of cabinets are EVA edge banding. EVA edge banding has a long history, the technology is quite mature, and the cost can be controlled very low.
Disadvantages of EVA edgebanding
1. Easy to overflow glue
EVA edge sealing requires a lot of glue, so there is a problem of "overflowing glue". Especially for light-colored boards, there will be obvious glue lines on the surface, affecting the aesthetic effect and flatness. EVA edge sealing is sensitive to temperature, and higher temperatures will also cause overflowing glue and cracking problems

2. Low environmental performance
EVA edge sealing uses more glue and has poor environmental performance and durability.

PUR edge banding, the full name of which is PolyUrethane Reactive, has almost the same process as EVA edge banding. Both require high-temperature heating, applying glue to the cut surface and finally extruding and bonding the edge banding strips.
Advantages of PUR edge banding：
1. After heating, the PUR edge banding adhesive reacts with moisture in the air, absorbs moisture in the air, and solidifies. After solidification, it will not melt even if heated again, so it will not be affected by temperature and cause cracking of furniture panels. It has stronger waterproof properties and is more suitable for use in kitchens and bathrooms than EVA.
2. PUR edge banding uses less glue. Whether it is a light-colored or dark-colored board, PUR edge banding will not produce obvious glue lines, and its aesthetics far exceed that of EVA edge banding.

3. PUR hot melt adhesive does not contain water or solvents. It is a high-performance, environmentally friendly adhesive with excellent water resistance, extreme corrosion resistance, and high-temperature resistance. It has good operability, can better meet environmental protection requirements, improve the edge sealing process, and solve the formaldehyde release problem.

4. EVA edge banding: suitable for general furniture and scenes with low durability requirements. PUR edge banding: widely used in scenes that require high durability and environmental protection, such as high-end furniture, kitchen and bathroom products

PUR is really much better than EVA edge sealing in terms of durability, environmental protection performance, and edge sealing adhesion.

Edge banding is not only a detail in furniture manufacturing but also a key factor in determining the quality and service life of furniture. When purchasing furniture, be sure to pay attention to the quality of edge banding to ensure the health of your family and the long-term use of the furniture!
