Kraft Compostable Leakproof Food Box: The Ultimate Eco-Friendly Delivery Solution

Sustainable Performance for High-Volume Eco-Conscious Catering

For brands committed to reducing their plastic footprint, our Kraft Compostable Leakproof Containers offer a high-performance, plastic-free alternative to traditional takeaway packaging. These boxes feature a natural Kraft exterior and a plant-based, compostable lining that provides a superior moisture barrier. Designed with folded, webbed corners, they are engineered to be 100% leak-proof, making them the perfect choice for everything from steaming hot pasta and stir-fries to chilled, dressed salads.

At Fresh Pack Solutions, we help you bridge the gap between "green" values and the practical demands of the UK’s busy food delivery sector.

Thermal Performance & Delivery Logistics

• Heat Retention: The thick-walled Kraft board provides natural insulation, keeping food at a safe and enjoyable temperature (60°C+) for approximately 20–30 minutes when kept in a closed environment.

• Moisture Control: Unlike non-breathable plastic, the compostable Kraft material allows a controlled amount of steam to escape. This prevents fried foods, like calamari or spring rolls, from becoming soggy while maintaining the heat of the main dish.

• Stacking Reliability: These containers feature a secure tuck-top interlocking lid and reinforced vertical walls, allowing you to stack up to 4 units high in a delivery bag without the bottom box bowing or collapsing.

Compliance & Eco-Credentials

• 100% Plastic-Free: These containers utilize a biopolymer lining instead of traditional petroleum-based PE, meaning they will break down in commercial composting facilities.

• Leak-Proof Assurance: The unique folded construction eliminates the gaps found in standard cardboard boxes, providing a seamless basin that holds liquids, oils, and hot gravies without seepage.

• Safe Transport: These boxes feature a flat, stable base that sits perfectly inside our Heavy-Duty Paper Carrier Bags, ensuring your delivery arrives upright and organised.
