FSC Certified Kraft Tray Box with Soy Ink Food-Safe Packaging

Product Overview

The FSC-certified kraft tray box with soy-based ink is purpose-built for food brands that refuse to compromise between sustainability and food safety. Every component — from the FSC Chain-of-Custody certified kraft board to the soy-based offset inks to the water-based adhesive — is food-contact safe and fully compostable in industrial facilities (EN 13432 certified). Manufactured by Guangdong Bincai Color Printing Co., Ltd. — ISO 9001:2015 and FSC certified with 22 years of packaging expertise — this tray box is printed on our KBA 1050 4-color offset press with vegetable-based inks that contain zero petroleum-derived solvents. Our 18,000 sqm Foshan factory (10,000+8,000 smart factory) has a dedicated food-grade production zone with positive air pressure, UV-C sterilization, and full material traceability from forest to box.

Design Features

• 100% Compostable Construction: FSC-certified kraft board (300-400gsm) + soy-based ink + water-based starch adhesive — no plastic, no petrochemicals, no synthetic laminates. Certified compostable to EN 13432.
• Foldable Tray Architecture: Die-cut self-locking tray design — ships flat, assembles in 2 seconds. Corner locking tabs eliminate adhesive at assembly points, preserving food safety integrity.
• Soy-Based Offset Printing: Vegetable-derived ink with <2% VOC content (vs. 30-40% for conventional petroleum inks) — vibrant CMYK reproduction without toxic off-gassing. FDA 21 CFR compliant for indirect food contact.
• Grease-Resistant Interior: Natural clay-coated kraft liner provides moisture and grease barrier without plastic PE/PLA lamination — suitable for baked goods, pastries, and dry food products.
• No Plastic Window: Die-cut open window or optional compostable PLA film window — never PVC or PET.

Applications

• Artisan Bakeries: Croissants, sourdough loaves, cookies, and pastries — stackable tray design for counter displays.
• Organic Food Brands: Granola, energy bars, dried fruit, nuts, and superfood powders — eco-packaging that matches organic brand values.
• Meal Kit Services: Ingredient portion trays, recipe card holders, and spice sachet organizers — compostable alternative to plastic clamshells.
• Farmers’ Market Producers: Honey jars, jam pots, preserves — tray insert with die-cut holes for jar stability.
• Tea & Coffee: Loose leaf tea pouches, coffee bean samplers, tea bag envelopes — the kraft aesthetic communicates artisanal quality.
