FAQ

Q1: Does molded pulp pass ISTA tests?

A: Yes — molded pulp cushioning is routinely validated to ISTA 3A parcel-transit procedures and ASTM D4169 practice when geometry matches the product.

Q2: What is ISTA 3A?

A: ISTA 3A is the standard transit-test procedure for parcel-delivery packaged products under 70 kg (150 lb).

Q3: How is passing achieved?

A: Wall thickness, ribbing, and cavity geometry are engineered to the product weight and drop height, then verified by testing prototypes.
