Molded Pulp Trays: A Complete Guide to Eco-Friendly Packaging Trays

Last updated: August 26, 2026

Molded pulp trays are protective packaging inserts formed from recycled paper, wood pulp, bamboo pulp, or sugarcane bagasse. They are widely used to hold, cushion, and display products in food service, medical device packaging, cosmetics, consumer electronics, and fresh produce. As brands seek biodegradable alternatives to plastic and foam, molded pulp trays have become a practical, cost-effective solution that meets both regulatory requirements and corporate sustainability goals.

The Problem: Plastic and Foam Packaging Under Pressure

Most conventional inner packaging still relies on expanded polystyrene (EPS) foam, plastic vacuum-formed trays, and PE foam inserts. These materials provide cushioning, but they create long-term waste, take centuries to degrade, and are increasingly regulated.

The European Packaging and Packaging Waste Regulation (EU) 2025/40 entered into force on February 11, 2025, requiring all packaging to be recyclable by January 1, 2030. This is not an isolated trend. Plastic restriction policies in North America, Southeast Asia, and other export markets are pushing manufacturers to find packaging that is protective, cost-effective, and compliant.

Buyers face a specific set of problems with traditional packaging:

• High logistics weight: Foam and heavy paper boxes increase shipping cost and limit stacking efficiency.
• Compliance risk: Plastic components may violate export regulations or fail recyclability requirements.
• Poor product fit: Standard trays and foam inserts do not securely hold complex product shapes.
• Brand perception gap: Plastic inner packaging conflicts with a brand’s environmental positioning.

What Is Molded Pulp Packaging?

Molded pulp packaging is made from natural plant fibers that are formed under pressure into a rigid, lightweight structure. The primary raw materials used by Tonghe Paper Co., Ltd. are sugarcane pulp, bamboo pulp, and wood pulp. The process is water-based, does not require harmful chemical additives, and the finished product is fully recyclable and biodegradable.

Dongguan Tonghe Paper Co., Ltd. is a professional pulp molding manufacturer in Dongguan, Guangdong, China. The company transforms recycled paper and bagasse fiber into eco-friendly packaging solutions that serve as biodegradable alternatives to disposable plastic and foam packaging. Tonghe’s molded pulp packaging covers electronics, lighting, gifts, food, wine, and medical device applications.

How Molded Pulp Trays Are Made

1. Pulping: Raw fiber material is mixed with water to form a slurry. No harmful chemical additives are used.
2. Forming: The slurry is vacuum-formed over a mold to create the tray shape. Tonghe operates complete forming and hot-pressing equipment in multiple automated production bases.
3. Hot pressing: The formed tray is pressed and dried to achieve density, surface finish, and dimensional accuracy.
4. Trimming: The tray is trimmed for clean edges and then inspected or packaged for shipment.

Why Buyers Are Switching to Molded Pulp Trays

Molded pulp trays are not just an environmental choice. They address operational and commercial concerns across the supply chain.

1. Regulatory Compliance and Export Readiness

The EU requires all packaging to be recyclable by January 1, 2030 under Regulation (EU) 2025/40. Many global brands are already moving ahead of this deadline to avoid compliance risk. Molded pulp trays meet recyclability and biodegradability requirements in the EU, North America, and other markets. Tonghe products comply with international environmental standards including SGS RoHS and PFAS-free requirements.

2. Logistics Cost Reduction

Lightweight packaging directly supports cost reduction. Tonghe’s molded pulp trays are about 50% lighter than traditional hard gift boxes. The reduced weight and stackable structure allow more products per pallet and container, lowering storage space, fuel consumption, and long-distance freight cost. In contrast, heavy foam packaging limits stacking layers and increases transportation loss.

3. Reliable Product Protection

Shock absorption and vibration damping are essential for fragile items. Molded fiber trays are formed to the exact contour of the product, preventing movement and impact. Moisture content is controlled to ≤8–12%, which reduces the risk of dampness-related damage. Edge crush strength can reach 8 kN/m, providing strong stacking performance in secondary packaging.
