Edgebanding peeling is one of the most common failures in cabinet manufacturing. This guide explains the main causes behind peeling and provides professional solutions related to materials, adhesive selection, machine settings, and environmental factors.
1. The 8 Fundamental Causes of Edgebanding Peeling
- Incorrect or low-quality edging material – cheap PVC or brittle ABS can warp or crack.
- Improper glue type or glue temperature – EVA softens too easily; PUR requires precise control.
- Insufficient adhesive application – uneven glue lines weaken bonding strength.
- Board moisture problems – swelling or shrinking pushes edging off.
- Temperature differences – cold materials reduce glue penetration.
- Incorrect edge bander pressure – too low or too high affects adhesion.
- Warped or curved panels – prevent uniform bonding.
- Environmental stress – heat, humidity, steam, UV, and chemicals accelerate peeling.
2. Choosing the Right Edgebanding Material
- PVC – versatile, cost-effective; suitable for closets and general cabinetry.
- ABS / MABS – more stable and eco-friendly; ideal for kitchens and bathrooms.
- Acrylic (PMMA) – best for high-gloss panels; excellent reflectivity and durability.
3. Anti-Peeling Strategies for Different Spaces
Kitchens
Use ABS, MABS, or high-quality PVC; PUR adhesive recommended.
Bathrooms
Use ABS edging with PUR or laser bonding for maximum moisture resistance.
Closets
Matte or textured PVC is sufficient; 0.4–1mm thickness depending on design.
4. EVA vs PUR Adhesive
- EVA: economical, easy to use, but weak against heat and steam.
- PUR: superior bonding, waterproof, long-lasting, nearly invisible glue line.
5. When Peeling Problems Appear
- White lines: PVC shrinkage or EVA crystallization.
- Corner lifting: insufficient pressure or rough board edges.
- Bubbling: uneven glue or cold materials.
6. Moisture, Temperature & Panel Flatness
- Ideal board moisture: 6–10%.
- Material temperature: 18–30°C.
- Boards must be flat before edging.
7. How to Extend Edgebanding Lifespan
- Use high-quality edging materials.
- Choose correct thickness (1–2mm for kitchens).
- Use PUR in heat or moisture environments.
- Maintain stable storage temperature.
- Ensure proper roller pressure and calibration.
- Avoid strong chemical cleaners.
With proper material selection and process control, edgebanding can last 5–10 years longer.
