High end PE for custom foam packaging

Packnet uses many different types of foams for custom packaging. Durability, cushioning, cost, reusability and density are just a few of the considerations when selecting the best foam for the job.

Cross linked polyethylene and extruded polyethylene are two of the more common foams used for challenging requirements. The two foam types are interchangeable for many applications as both have good cushioning ability and can be die cut or water jet cut. Cross linked PE has more durability and compression strength, extruded PE is good where heat bonding is required. Below is a table that compares the foams for each type of application:

Application Cross linked PE Extruded PE
End Caps Not used Preferred
When heat bonding is required Good Preferred
When cosmetic appearance is important Preferred Not desirable
For products that are scratch sensitive Preferred Not desirable
Reusable packaging Preferred Not desirable
Pressure sensitive adhesive bonding Preferred Not desirable
For cleanroom applications Preferred Not desirable
