When sourcing multiple photo frames, the choice of material directly impacts durability and perceived value. Solid wood (oak, pine, or walnut) is preferred for premium markets due to its longevity and natural grain. For cost-sensitive or high-volume retail, MDF (Medium Density Fiberboard) with wood-grain veneers or high-quality PS (Polystyrene) offers a lightweight and economical alternative. Ensure the front cover is tempered glass for clarity and scratch resistance, or high-transparency acrylic (Plexiglass) for shatterproof safety in shipping and child-friendly environments.
