When comparing prices, you must look beyond the surface. The base material (usually MDF or Particle Board) significantly impacts the cost; High-Density Fiberboard (HDF) is more expensive but offers better moisture resistance. The PVC film thickness is another critical factor—standard films are 0.15mm to 0.18mm, while premium, scratch-resistant films reach 0.30mm to 0.35mm. Additionally, ensure the supplier uses PUR (Polyurethane) adhesive for vacuum pressing, as it prevents delamination in high-temperature kitchen environments.
