FAQ
Q: Is this bento box truly compostable — what happens to the PLA coating?
A: Yes — the entire box is certified compostable per EN 13432 (European standard for industrial composting). The PLA coating — derived from corn starch or sugarcane — biodegrades alongside the kraft board in industrial composting facilities at 58°C ±2°C with controlled humidity. Complete disintegration occurs within 12 weeks, and ≥90% biodegradation (conversion to CO₂, water, and biomass) within 6 months. We provide the EN 13432 certificate from TÜV or DIN CERTCO with every order. Note: this product requires industrial composting — it will NOT break down in a home compost pile or marine environment at the same rate.
Q: How well does the PLA-coated kraft board handle hot, saucy, and oily foods — will it leak?
A: The PLA coating creates a continuous moisture and grease barrier that withstands hot foods up to 100°C. In our testing, the box holds saucy dishes (curry, pasta with tomato sauce, stir-fry with oil) for 4+ hours at ambient temperature without softening, leaking, or grease staining through the board. For extended hot-holding (>4 hours at >80°C), we recommend the 450gsm heavy-duty board option. The locking-tab closure and folded-corner construction provide additional mechanical leak protection at seam lines. Freezer-to-microwave performance: the box can go directly from freezer (-20°C) to microwave (reheat at ≤800W for ≤3 minutes).
Q: Can we brand the box with our restaurant logo and customize the compartment layout for our specific menu items?
A: Absolutely. Logo printing is available in 1-color, 2-color, or full CMYK flexo/offset using soy-based inks. Branding areas include the lid exterior, lid interior, and side panels. For compartment customization, our die-board engineering team designs the layout based on your menu items — for example, a large main compartment + two small side compartments + a circular sauce cup recess. New compartment tooling requires a new die-board (7-10 days, included in sampling) and MOQ of 3000 units. We can also print heating instructions, nutritional information, and QR codes linking to your menu or sustainability story.
Q: What certifications do you hold and can you provide documentation for our sustainability claims?
A: We hold FSC chain-of-custody certification (certificate available upon request) for the kraft board, EN 13432 compostability certification (TÜV/DIN CERTCO) for the complete box, and EU 1935/2004 food contact safety compliance documentation. Our factory is ISO 9001:2015 certified with full batch traceability. We provide a documentation package with every order: FSC certificate, EN 13432 certificate, EU 1935/2004 declaration of compliance, and ISO 9001 certificate. This documentation supports your own sustainability marketing claims and regulatory compliance in EU, UK, and North American markets.
