An EPP (Expanded polypropylene) case may not be the most obvious choice for a package, but it is often the best material for the job.
The material is extremely lightweight. Products with oversize dimensions often need heavy cases, but not if the case uses EPP in its production. An EPP case is many times lighter than a plastic case of the same dimensions, so it is ideal for transporting relatively large products that still need to be easy to carry.
Despite their lightweight nature, EPP cases are still robust and extremely shock-absorbent. The material is also resistant to oils and acids, which makes it ideal for use with tools and machines.
EPP cases are made using a mould, giving complete freedom in determining their form and dimensions. This has the disadvantage of requiring higher start-up costs, but if you need a series of cases, an EPP case can quickly become a competitive option.
