Given the fragility of computer products like laptops, monitors and keyboards, it’s vital to protect these with a cushioned, durable packaging material. Foams such as polyurethane and polyethylene are perfect for this purpose.

Polyurethane is a sponge-like, open cell foam with great consistency. It is commonly used for packaging sensitive, lightweight items and offers excellent protection of the most delicate and critical areas of technological units.

Polyethylene is more rigid and is also quite pliable and flexible. It is renowned for its exceptional recovery characteristics, which helps it maintain a level of dimensional stability, no matter how hard you bend it, it’s not going to break. It is a closed cell foam that is regularly used by packaging designers seeking a foam that doesn’t absorb liquids.
