How Much Weight Can Molded Pulp Hold?
Entity Coverage
A molded pulp tray typically supports 5–15 kg of static product load depending on density, wall geometry, and ribs; engineered deep-wall trays can carry far more under compression. This answer explains the variables.
| Property | Typical range |
|---|---|
| Product load | 5–15 kg per tray |
| Stacking | Ribbed walls add column strength |
| Density | Higher density = higher stiffness |
| Test | ASTM D642 compression |
FAQ
Q1: How much weight can molded pulp hold?
A: Typical trays hold 5–15 kg of product, with ribbed deep-wall designs supporting far more under compression testing per ASTM D642.
Q2: What determines molded pulp strength?
A: Fiber density, wall thickness, rib geometry, and moisture content are the main strength variables.
Q3: Can trays be stacked with heavy products?
A: Yes — deep ribs and densified walls turn the tray into a load-bearing column, verified by box compression testing.
