Compostable Tray Materials and Key Advantages
Introduction: Why Compostable Trays Are Gaining Attention
Plastic trays have been the go-to choice in food service for decades. They’re cheap, lightweight, and practical—but they come with a hidden cost. Once discarded, they linger in landfills for centuries, breaking down into harmful microplastics. Governments around the world are now banning single-use plastics, leaving restaurants, caterers, and food businesses searching for greener solutions.
That’s where Compostable Trays step in. Unlike plastic or coated paper trays, these trays are made from natural plant fibres and fully break down into harmless organic matter. They’re safe, strong, and designed to meet the real-world needs of modern food service.
What Are Compostable Trays?
In simple terms, compostable trays are disposable food trays made from renewable, plant-based materials such as sugarcane bagasse and bamboo fibre. They are engineered to be just as strong and functional as traditional plastic trays—but with one big difference: after use, they can be composted, turning into nutrient-rich soil instead of polluting the planet.
Unlike biodegradable plastics, which may still leave microplastic residues, compostable trays fully decompose under composting conditions within around 90 days. This makes them one of the most sustainable packaging options available today.
What Are Compostable Trays Made Of?
The secret to the performance of compostable trays lies in their raw materials:
-
Sugarcane bagasse – A fibrous by-product from sugar production. Instead of being discarded or burned, it’s repurposed into sturdy pulp. Rich in cellulose, bagasse gives compostable trays their rigidity and structure.
-
Bamboo fibre – Known for its strength and rapid renewability, bamboo adds flexibility and crack resistance. This blend ensures the trays can handle hot, oily, and heavy foods without breaking.
-
No plastic or wax coatings – Unlike paper trays lined with PE films, compostable trays don’t rely on synthetic barriers. They’re food-safe, free from harmful chemicals, and certified under FDA and LFGB standards.
This combination means compostable trays are not only eco-friendly but also safe and reliable in real food-service environments.
Key Benefits of Compostable Trays
Compostable trays bring together a unique mix of environmental responsibility, food safety, and practical performance. Let’s break this down in detail:
1. Environmental Benefits
-
100% compostable – They decompose within ~90 days in industrial composting, leaving only water, CO₂, and organic matter.
-
Supports waste reduction – Instead of adding to landfills, trays return nutrients to the soil, contributing to a circular economy.
-
Plastic-free and renewable – Made from sugarcane and bamboo, both fast-regenerating natural resources.
-
Compliant with global standards – Certified under ASTM D6400 and EN 13432, making them internationally recognised.
2. Food Safety and Material Performance
-
Heat resistance up to 200°C – Can hold hot meals straight from the oven or microwave without softening.
-
Cold resistance down to -20°C – Ideal for refrigerated or frozen meal storage.
-
Grease and water resistant – Suitable for curries, soups, and oily dishes without leaking or sagging.
-
No toxic chemicals – Unlike some plastics, compostable trays are free from BPA, PFAS, and other harmful additives.
3. Functional and Practical Advantages
-
Multi-compartment designs – Available in 2, 3, 5, or 6 compartments to keep food neatly separated. Perfect for schools, hospitals, and catering.
-
Microwave and freezer safe – Truly versatile for modern food service.
-
Strong structural integrity – Can handle heavy portions without bending or collapsing, unlike flimsy plastic trays.
-
Odour neutral – Won’t transfer any smells or tastes to food.
4. Business and Market Value
-
Regulatory compliance – Helps businesses meet plastic ban requirements in the EU, US, and Asia.
-
Boosts brand image – Consumers increasingly value eco-conscious choices. Using compostable trays positions a brand as sustainable and responsible.
-
Export-ready – Already trusted across the US, Europe, Japan, and Australia.
-
Supports customer loyalty – Many consumers actively prefer eco-friendly packaging when choosing where to buy food.
Compostable Trays vs Traditional Options
Here’s how compostable trays stack up against plastic and coated paper trays across multiple dimensions:
Criteria | Plastic Trays (PS/PP) | Coated Paper Trays | Compostable Trays (Bagasse/Bamboo) |
---|---|---|---|
Compostability | Not compostable | Limited (film residue) | Fully compostable (90 days) |
Raw materials | Petroleum-based | Paper + plastic lining | Renewable plant fibres |
Temperature range | -20°C ~ 120°C | 0°C ~ 100°C | -20°C ~ 200°C |
Oil/Water resistance | Moderate (can warp) | Needs PE coating | Naturally resistant |
Food safety | BPA/PFAS risks | Plastic coating issues | FDA & LFGB certified safe |
Environmental impact | High pollution, microplastics | Mixed recycling problems | Zero toxins, circular economy |
Durability | High but inflexible | Prone to leaking | Strong, flexible, multi-use ready |
Global acceptance | Being phased out | Limited regions | Approved worldwide, export-friendly |
This broader comparison makes it clear: compostable trays are not just “eco-friendly,” they are superior in performance, compliance, and versatility.
Where Can You Use Compostable Trays?
The versatility of compostable trays makes them suitable across industries:
-
Schools and hospitals – Safe, hygienic, and disposable, reducing cross-contamination risks.
-
Fast-food and catering chains – An eco-friendly solution for high-volume meal service.
-
Airlines and railway catering – Lightweight yet strong, with multi-compartment options.
-
Events and festivals – Ideal for large-scale use where disposables are necessary but sustainability matters.
Your company’s trays, for example, cover everything from 2-compartment lunch boxes to 6-compartment cafeteria trays, making them adaptable to virtually any dining scenario.
Conclusion: Compostable Trays Are the Future of Food Packaging
Compostable trays aren’t just a trend—they’re a fundamental shift in how we think about food packaging. By combining renewable plant-based materials with outstanding performance and global certifications, they meet the needs of businesses, consumers, and the environment alike.
If your goal is to reduce plastic waste, comply with global sustainability standards, and build an eco-friendly brand identity, compostable trays are the clear choice.
Keep it real. Keep it sustainable. Choose compostable trays.
