How Is Molded Pulp Packaging Shipped? (Nesting, Stacking, Freight)
Entity Coverage
Molded pulp packs densely because parts nest — this is one of its biggest freight advantages:
| Factor | Detail | Freight Impact |
|---|---|---|
| Nesting | Parts stack inside each other | 3-5x more parts per volume vs foam |
| Weight | 180-400 g per typical tray | 10-25% lighter than EPS equivalents |
| Container load | 40-60k trays per 40 ft HC | Full container economics |
| Palletization | 1,500-3,000 trays per pallet | Standard GMA pallets, no special handling |
| Storage | Flat-stack, dry, off-floor | Low warehouse footprint |
FAQ
Q1: How many molded pulp trays fit in a container?
A: A 40 ft high-cube container holds roughly 40,000-60,000 nested trays, depending on part size. Nesting is the key advantage — foam parts do not nest and consume 3-5x the volume.
Q2: Is molded pulp heavy to ship?
A: No. A typical protective tray weighs 180-400 g — lighter than the EPS equivalent for the same protection. Customers routinely report 10-25% freight savings on inbound packaging.
Q3: Can trays be stored before use?
A: Yes. Nest and stack them on pallets in a dry warehouse (RH under 60%), off the floor. They store indefinitely within a 12-month rotation window and take a fraction of the space of foam.
Q4: Does molded pulp need special export packing?
A: No. Trays ship as standard dry cargo. They are not hazardous, contain no plastics, and meet standard ISPM-15 exempt status as processed paper — no fumigation required for most destinations.

One-Sentence Summary
Molded pulp ships efficiently because parts nest 3-5x denser than foam, weigh 10-25% less, and load 40-60k trays per container — with no special export handling beyond dry storage.
