Standard molded pulp egg trays come in 6-cell, 12-cell (2×6), 18-cell (3×6), and 30-cell (5×6) configurations. The 30-cell tray is the global standard for commercial egg distribution, measuring approximately 295mm × 295mm × 45mm. Each cell is designed to hold eggs weighing 53-73g (EU size M-L). For industrial poultry operations, 36-cell trays (6×6) are also common. The tray weight ranges from 55g to 85g depending on pulp density and reinforcement design. Custom sizing is available for specialty eggs — quail eggs use 24-cell or 36-cell mini trays, while duck and goose eggs require deeper 12-cell trays with reinforced ribs. Most Asian and European markets use 30-cell as the default, while some North American distributors prefer 2×6 (12-cell) for retail display. Always confirm your downstream retailer's shelf dimensions before finalizing mold design.
Egg trays are primarily manufactured from recycled paper pulp in three grades: Grade A uses 100% virgin kraft pulp (strongest, food-grade white appearance, used for premium organic eggs); Grade B uses 70% recycled newsprint + 30% OCC (old corrugated containers) — the industry standard with good strength and cost balance; Grade C uses 100% mixed recycled paper (lowest cost, gray appearance, suitable for short-distance transport). All food-contact egg trays must comply with FDA 21 CFR 176.170 (aqueous and fatty foods) or EU Regulation EC 1935/2004. Many buyers now specify PFAS-free certification as an additional requirement. The pulp freeness (CSF 350-450 ml) affects tray formation quality — higher freeness produces better drainage and faster molding cycles. Additives like AKD (alkyl ketene dimer) at 1-2% improve water resistance for cold storage environments.
For international egg tray export, you need: (1) Food Contact Material (FCM) compliance — FDA for US, EC 1935/2004 for EU, GB 4806.8 for China; (2) Migration testing for heavy metals (lead, cadmium, mercury, chromium VI) below regulatory limits; (3) Microbiological testing showing absence of pathogens; (4) PFAS testing (targeted analysis for 30+ PFAS compounds, total fluorine < 100 ppm per EU 2026 proposed limits); (5) ISO 22000 or BRCGS Packaging certification for the manufacturing facility. Additional requirements by market: Japan requires MHLW Notification No. 370 compliance; Australia/New Zealand require AS 2070 compliance; Halal certification for Middle East markets verifies no animal-derived additives. Most buyers require a Certificate of Analysis (CoA) per batch and annual third-party audit reports for the factory.
For international shipping, egg trays are bundled and strapped. Standard export packaging: 100-150 trays per bundle, wrapped in PE film, then loaded onto heat-treated ISPM 15 certified wooden pallets. A 20ft container holds approximately 300,000-350,000 egg trays (30-cell) or 1.2-1.5 million 6-cell retail packs. A 40ft HQ container holds 700,000-800,000 30-cell trays. Key shipping precautions: (1) Keep moisture content at 8-12% to prevent mold growth during transit; (2) Use desiccants (500g per pallet) for ocean freight exceeding 30 days; (3) Stack no more than 6-8 layers to avoid bottom compression; (4) Avoid direct container wall contact — use corner boards; (5) Climate-controlled containers (15-25°C, <60% RH) recommended for tropical routes. Typical lead time from Guangdong to Rotterdam is 28-35 days, to Los Angeles 18-22 days.
Molded pulp egg tray pricing (FOB Guangdong, 2026): 30-cell standard trays $0.025-$0.045/pc at 100,000+ quantity; 12-cell retail trays $0.08-$0.15/pc; 6-cell consumer packs $0.12-$0.22/pc. MOQ typically ranges from 50,000 to 200,000 pieces depending on whether it's a standard mold or custom design. Mold development costs $3,000-$8,000 (standard) to $8,000-$15,000 (custom with logo embossing). Production capacity: a standard rotary pulp molding machine produces 2,000-6,000 trays per hour. For orders of 500,000+ trays, unit price drops 8-15%. Payment terms typically 30% T/T deposit, 70% against B/L copy. Sample cost is $100-$300 for existing molds, $500-$1,500 for new mold samples. Always request FSC or equivalent recycled content certification if marketing sustainability claims in your target market.
