Polyurethane foam, often called PU foam, is a soft, flexible open cell foam whose connected cells let air move freely as the foam compresses, so it gives way under light pressure and then recovers its shape. That softness lets PU foam wrap gently around glassware, instruments, electronics, and cosmetics, spreading contact across the surface instead of concentrating it at a few hard points. Polyurethane foam also comes in a range of firmness levels and colors, and our team often pairs a soft PU top layer with a firmer polyethylene base, giving your product a gentle touch on top and solid support underneath. We cut polyurethane foam to the exact form your packaging needs and match its firmness to your item, so fragile products ship protected and present beautifully when your customer opens the box.
PU foam wins the job when your product needs a soft, forgiving cushion rather than rigid bracing. Our customers choose it for four core reasons.
𓂃
Polyurethane foam molds around curves and irregular shapes, cradling delicate items so they cannot rattle or press against hard edges.
♧
Open cell PU foam soaks up the vibration and small bumps of transit, protecting sensitive components and thin glass from fatigue and cracks.
