Vertical compressive strength (ASTM standard)
Resistance to applied force.
Unit of measure: pound / square inch (PSI)
25% and 50% compression foam thickness, and then measure the relative strength.
The advantage of the data in the calculation of the compression area of the packaging design:
- Strong elastic foam
- Less foam needed (to reduce the cost of packaging materials)
- Packing small size (reduce the cost of packing box, increase the capacity of the container and container)
