Foam is widely used as protective packaging material from shock and vibration which is an environment the product will be exposed for under the transportation or in the handling of the packaging. Packaging solutions are designed based on product fragility, method of transportation, destination and any special circumstance.

• Excellent protection from shocks and vibrations
• Customizable
• ESD and corrosion protection available
• Moisture resistant and resilient
• Broad range of thicknesses, densities and models
• Resistant to humidity
• Lightweight

There are basically four different materials (polymers) and two main manufacturing techniques that are used to meet required specifications.

Foams can be either moulded or converted. Moulding demand more complicated tooling but is often an economically preferable choice for large quantities.  

Polyethylene (PE or EPE) is the most widely used polymer that can be moulded as well as fabricated depending on the requirements. It is a moisture resistant and resilient packaging material with good multiple drop cushioning performances. One main feature with PE is the possibility to recycle it.
Polypropylene (PP or EPP) is a moulded foam that just like polyethylene is a moisture resistant and resilient material with good multiple drop cushioning performances.
 Polystyrene (PS or EPS) is a moulded foam with good insulation capability and good first drop cushioning performance.

Polyurethane (PU) is commonly fabricated but can also be moulded. The material is recognised as mattress or furniture material and is suitable as cushioning for light weight products and as interior packaging in cases.

Frequently mentioned groups of foam profiles are:
·  U-profile – for edge and corner protection
·  L-profile – for corner protection
·  WS-profile – for wind screens and other glass products
· O-profile – protection for tubes, pipes, poles etc
·  C-profile – edge and corner protection for special applications
·  System profile – designed to give shock and vibration protection to sensitive products
 
Foam materials are usually sold to solve a problem for the customer.It always a case to case business. Bring home the problems that the customer have, find a solution of the problem and present a very good design who is easy to pack, easy to unpack. UPP enjoys a great win-win with customers due to its speed, design and functionality.
