Custom-cut protective packaging

Custom-cut protective packaging consists of flexible PU foam pieces cut according to the geometry of specific products, used to protect fragile items during transport and storage. They are found in professional equipment cases (cameras, medical equipment, precision instruments), luxury product boxes (jewelry, watches, premium cosmetics), packaging for fragile electronics (laptops, monitors, IT equipment), and industrial transport of delicate parts.

The process starts from slabstock foam buns cut into slabs, then punched or milled with cavities according to the product design. Common techniques include hot-wire cutting, CNC water-jet cutting, laser cutting (for maximum precision), and die-punching. Densities vary considerably depending on application: low densities (20–30 kg/m³) to absorb light impacts, medium densities (35–50 kg/m³) for structural protection, almost-flexible rigid foams (60–80 kg/m³) for very heavy products.

A specific and growing variation is anti-static (ESD) foam — formulations with conductive additives that dissipate electrostatic charges, critical for packaging sensitive electronic components (boards, processors, sensors). Another variation is reticulated foam, where cells are fully open, used for filtration, ventilation and specific applications where conventional block does not serve.
