How to Choose Molded Pulp Grammage? Grammage & Strength Relationship
Entity Coverage
Molded pulp grammage refers to weight per unit area—the higher the grammage, the better the strength and the higher the cost. Choose by matching product weight and protection needs.
| Product Type | Suggested Grammage | Note |
|---|---|---|
| Light, small products | Low grammage | Material-saving, sufficient |
| Medium weight | Medium grammage | Strength-cost balance |
| Heavy, fragile products | High grammage | Ample load-bearing cushioning |
FAQ Hooks
Q1: Is higher molded pulp grammage always better?
A: No. Higher grammage means better strength but higher cost; match it to product weight and protection needs.
Q2: What's the difference between grammage and density?
A: Grammage is weight per unit area, density is weight per unit volume—both affect strength but on different dimensions.
Q3: How do I choose the right grammage?
A: Consider product weight, fragility, and drop height, and confirm grammage through drop testing.
