When sourcing ODM 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 natural grain and longevity. For cost-effective bulk orders, MDF (Medium Density Fiberboard) with high-quality veneers or PS (Polystyrene) moldings are excellent alternatives as they are lightweight and moisture-resistant. Ensure the glazing is either high-transparency tempered glass or shatterproof acrylic (Plexiglass), especially for frames larger than 12x16 inches to reduce shipping breakage.
