Material Overview

The Versatile Workhorse of Protective Packaging

PE foam is one of the most widely used foam materials in the world and for good reason. Its closed-cell structure delivers reliable shock absorption, moisture resistance, and surface protection across a broad range of densities. Unlike open-cell foams, PE does not absorb water or harbour bacteria, making it a clean, durable choice for packaging, insulation, and component protection. kristoFOAM stocks planks, sheets, rolls, and fabricated parts in a variety of densities and colours ready to be cut, laminated, or moulded to your exact specifications.

Excellent Shock Absorption

PE foam's resilient closed-cell structure absorbs and dissipates impact energy effectively, protecting fragile or sensitive products throughout the full part life cycle from manufacturing to end use.

Moisture & Abrasion Resistant

The closed-cell matrix prevents water ingress and resists surface abrasion, keeping packaged goods dry and scratch-free even in demanding shipping and storage environments.

Lightweight & Cost-Effective

PE foam delivers strong protective performance at a low weight and cost, making it the preferred choice for high-volume protective packaging applications where efficiency matters.

100% Recyclable

Polyethylene foam is fully recyclable within the standard PE recycling stream supporting sustainable packaging initiatives and circular economy goals without compromising performance.

Common Uses

Where PE Foam Is Used

From retail consumer packaging to heavy industrial crating, PE foam's combination of shock absorption, moisture resistance, and cost-effectiveness makes it the go-to material across dozens of industries.

Custom die-cut foam inserts, end caps, and wrap materials for consumer electronics, appliances, glassware, and industrial components requiring reliable transit protection.

Plank, sheet, and roll stock used as flexible void fill and dunnage in shipping cartons and returnable containers to prevent movement and impact damage.

Tube and sheet PE foam for pipe insulation, HVAC ducting, and thermal barrier applications providing low moisture absorption and consistent R-value performance.

Door seals, trunk liners, under-hood padding, and component protection for automotive manufacturing and aftermarket lightweight and oil resistant.

Flotation aids, exercise mats, camping pads, and protective padding for sporting equipment lightweight, moisture resistant, and easy to fabricate into complex shapes.

Clean, non-outgassing PE foam for medical device packaging, laboratory equipment inserts, and specimen transport cases requiring a hygienic, non-reactive material.
