A PU foam packing machine dispenses a two-component polyurethane mix directly at the packing line, expanding around the product to form a protective cushion in seconds. It replaces pre-cut foam inserts for irregular or fragile items, and runs in high-pressure or low-pressure configuration depending on output volume.
Within a very short time to provide rapid positioning for large of manufactured goods, fine buffer and space filling full

When to Choose Foam-in-Place Packing
Pre-cut foam inserts are cut to a fixed shape, so irregular parts, asymmetric assemblies, or one-off shipments often end up with gaps that let the product shift in transit — a common cause of damage claims under transit-testing protocols such as ISTA. A PU foam packing machine dispenses liquid foam directly around the product at the point of packing, so the cushion forms to the exact contour of the item instead of a pre-molded shape.
Output configuration matters for packing lines specifically: high-pressure systems suit higher-volume, continuous packing runs where cycle time matters, while low-pressure systems suit lower-volume or mixed-product lines where formula and mix-ratio changes happen more often. Both use the same two-component polyurethane chemistry described by material bodies such as PU Europe. This on-site model is a good fit for custom cushion packing and void-fill of fragile goods; where a shipment instead needs a fixed molded cushion produced in advance rather than at the packing line, see our PU foam packaging machine page for that configuration.
