Packaging & Protective Foam
Protective foam for packaging, transit, flight cases and tool trays, cut to order in our UK factory.
Important: packaging foams are not fire rated and must not be used for upholstery. UK furniture requires Crib 5 rated foam. If you are making or re-covering furniture, use our upholstery range instead.

A simple rule
If you are protecting something in a box and cost matters, use the open cell packaging foam. If you are protecting something that would genuinely hurt to lose — instruments, medical kit, cameras, tooling — or if it might get wet, use the Plastazote.
