Polyethylene (PE) Foam
Closed-cell, durable, and available in a wide range of densities - PE foam is the most commonly used industrial packaging foam. Excellent shock absorption, moisture resistance, and a long service life make it the default choice for general industrial packaging.
Properties
Key physical and performance characteristics of this foam grade.
Density Options
Choose the right density based on product weight, fragility, and retention requirements.
| Density | Firmness | Best For |
|---|---|---|
| 1.2 lb/ft³ | Soft | Light, fragile items - glassware, optics, sensors |
| 1.7 lb/ft³ | Medium | General industrial - most common all-around choice |
| 2.2 lb/ft³ | Firm | Heavier products, tight retention pockets |
| 4.0 lb/ft³ | Very Firm | Structural blocking, heavy equipment bracing |
When to Use It
Industries and use cases where this foam type performs best.
Industrial Parts
Machined components, castings, and assemblies shipped repeatedly in custom PE pockets.
Electronics Packaging
Non-ESD electronics, power supplies, and enclosures cushioned in high-density PE.
Medical Devices
Instruments and non-sterile devices nested in dense PE for protection and immobilization.
Automotive Components
Precision parts and finished components protected from transit shock and vibration.
Reusable Shipping Cases
PE's recovery characteristics make it ideal for multi-cycle depot and field cases.
Heavy Product Support
High-density PE provides structural blocking and bracing for heavy items in transit.
