For industries and companies requiring product and packaging protection, efficient, versatile, and cost-effective solutions are vital. In this context, Sealed Air PE presents an innovative alternative offering numerous advantages to streamline processes and ensure effective product protection.

We delve deeper into Sealed Air PE, outlining its advantages and explaining why it serves as an efficient, cost-effective, and, most importantly, versatile solution.

What is Sealed Air PE?

PE, also known as Expanded Polyethylene or polyethylene foam, is a flexible, lightweight plastic material made from expanding polyethylene granules. This process gives it a unique cellular structure, known as closed-cell, characterized by its low density and high impact absorption capacity.

Sealed Air, on the other hand, refers to the low-density, closed-cell polyethylene foam branded as Sealed Air. It's a lightweight foam available in blocks and rolls that provides high grip and low slippage to protect the product. The closed-cell foam rolls are non-abrasive and protect against scratches and stains without leaving a greasy residue.

Sealed Air PE manufacturing process

The characteristics of this material stem from its manufacturing process. To better understand its advantages, it's essential to know its manufacturing process. Here's a brief description of the process:


As the first step, the polyethylene granules are melted and extruded through a die, creating a plastic film.


The film undergoes expansion through the use of an expanding gas, such as nitrogen or carbon dioxide, creating a low-density cell structure.


The expanded foam is then cooled and solidified, resulting in Sealed Air PE in its final form.

Advantages of Sealed Air PE in the packaging industry

Every material possesses unique structural characteristics that make it suitable for various purposes. The case of Sealed Air PE is no exception. That's why below, we present the main advantages of this material.

Excellent cushioning properties

The cellular structure of Sealed Air PE provides it with energy-absorbing and shock-absorbing properties, effectively shielding your products from shocks, vibrations, and damage during transportation and storage.

High compressive strength

Sealed Air PE can withstand high loads without deformation, making it an ideal choice for fragile or heavy products. Additionally, it ensures that products retain their properties intact during distribution or storage.


It adapts to different shapes and sizes of products, providing customized protection. This is because you can cut it to the shape and size you need. Alternatively, at Worldwide Foam, you can order it in the thickness you require, either in block or roll.

Low cost

Sealed Air PE offers an economical alternative to other polyethylene foams for traditional packaging, without sacrificing its cushioning and strength properties.


Thanks to its closed-cell structure, it helps reduce the overall weight of the packaging. This results in savings in transportation and storage costs, as well as the ability to transport more products simultaneously.

Easy to use

Sealed Air PE can be easily handled and cut, simplifying the packaging process.


Sealed Air PE dissipates static electricity, protecting sensitive electronic components from ESD damage. This makes it an excellent choice for household appliances, electronic devices, among others.

Thermal insulation

Sealed Air PE boasts excellent insulating properties, making it ideal for maintaining the temperature of climate-sensitive products.

Acoustic insulation

The cellular structure of Sealed Air PE absorbs sound, making the material an ideal choice for noise reduction in specific applications.

Sealed Air PE applications in the packaging industry

Here are some applications and solutions offered by Sealed Air PE, which, thanks to its characteristics, work excellently for the following:

  • Packaging of Fragile Products: Electronics, household appliances, glassware, ceramic items.

  • Packaging of Heavy Products: Machinery, tools, automotive parts.

  • Thermal Insulation: Perishable foods, medicines, temperature-sensitive products.

  • Moisture Protection: Electronic products.

  • Void Filling: Space optimization in boxes and packaging.

  • Acoustic Insulation: Industrial equipment, machinery, acoustic panels.

This is why Sealed Air PE is presented as an integral solution for the packaging industry, offering a unique combination of properties that make it the ideal option to protect your products efficiently, economically, and sustainably.
