Proper performance of packaging is dependent on its proper design and use. An engineer needs to know the severity of shock (drop height, etc.)
to protect against. Knowledge of the product to be packaged is critical. Field experience may indicate the types of damage previously experienced. Sometimes a product can be made more rugged or can be supported to make it less
susceptible to breakage. Polystyrene Packing Sheets can offer the support and protection required.
Expanded polystyrene (EPS) is the one we are all most familiar with. Mainly used in packaging. A foaming agent is added to beads during or just after polymerisation; steam then heats the beads causing the foaming agent
to expand.
