This custom printed clamshell burger box is made of FSC-certified food-safe kraft paper with plant-based greaseproof coating, free of toxic fluorescent additives and fully compliant with FDA food contact standards for hot greasy burgers, fried chicken and sandwich meals. Eco-friendly flat foldable one-piece design can be stacked flat to save warehouse space and reduce bulk shipping costs for burger shops, food chains and delivery catering brands. Integrated snap lock structure achieves tight leak-proof sealing, with optional reserved vent holes to discharge steam and keep burger crust crisp during long-distance transit. Full customization covers box sizes, kraft/white base color, full CMYK/Pantone brand logo printing and fast food decorative patterns. Multiple food-safe finishing crafts are available including matte glossy waterproof lamination, spot UV coating, embossing debossing and food-grade hot foil stamping. Thickened rigid paperboard resists extrusion deformation and oil seepage, suitable for dine-in, takeaway and cross-border fast food wholesale. All dimensions, anti-oil coating styles and printing samples displayed are reference only. Custom size matching, waterproof surface treatment and paper grammage plans need full communication with our factory team.
