Flexible Polyurethane Foam Packaging

Commonly known as polyether or soft polyurethane foam (PU), this open-cell, flexible foam is a versatile packaging material with a wide range of applications. Lightweight and compressible, it offers excellent shock absorption and moisture resistance — making it ideal for protecting fragile, valuable, or delicate items during transport or storage.

Available in a variety of colours and densities (typically 12–30 kg/m³), polyurethane foam is highly flexible, meaning it can be compressed repeatedly and still return to its original shape. Flame-retardant and anti-static grades are available, as well as 100% recycled chip foam (also known as reconstituted foam) for more sustainable options.

Why Choose PU Foam for Packaging?

  • Shock Absorption – The open-cell structure effectively cushions against impact and vibration.
  • Lightweight – Reduces overall shipping weight and cost.
  • Non-Abrasive – Gentle on sensitive surfaces such as electronics, glass, and polished metal.
  • Highly Customisable – Can be cut, shaped and bonded to suit specific packaging needs.

Typical Applications Include:

  • Electronics – Protection for sensors, circuit boards and delicate components.
  • Medical Equipment – Cushioning for sensitive and high-value instruments.
  • Glassware & Ceramics – Prevents chipping, cracking, or breakage.
  • Industrial Parts – Safeguards mechanical or precision components.
  • Luxury Goods – Adds a premium feel to jewellery, watches and bespoke products.

We manufacture custom foam packaging using CNC knife-cutting and die-cutting techniques. We can also bond PU foam to substrates such as corrugated cardboard, corrugated polypropylene (Correx®), paper honeycomb board, or timber to create complete protective solutions tailored to your product and supply chain.
