3 Types of Foam to Use as Custom Packaging Inserts


There are diverse packaging solutions in the industrial market for commercial and personal applications. The ideal choice for your products or equipment will depend on factors such as the vulnerability of the goods to damage, quantity, size and the complexity of the design. Custom foam inserts are commonly used in the storage and transportation of assorted types of products such as sensitive electronics, equipment parts, tools and vials.

These cases are designed to cradle the items in perfectly sized cocoons for safe transportation. The foam material is cut in custom shapes and sizes using techniques like water jet cutting, foam routing and die cutting. There are different types of foam raw materials used to create the case inserts. Here is a short description of the common categories to help you choose the best foam for your project.


Polyurethane packaging foam is a relatively flexible material which is available in different densities. It is a commonly used compound in case insert production and the colour found in the market is typically charcoal gray. The material is soft so it can absorb mechanical impact when protecting the packaged products. Moreover, you can purchase flame-retardant polyurethane if there are pertinent risks. The structure of the foam cells is open which means that the case inserts are similar to sponges. The packaging will allow absorption of water and air therefore it is not suitable for moisture-sensitive goods.


Polyethylene foam is dense and semi-rigid therefore it is the perfect choice for packaging heavy parts and equipment. In simple terms, this material can hold items of significantly high weights without sustaining significant damage. These case inserts have a prolonged lifespan so they can be wiped down and reused. The polyethylene foam has closed cells so it will not expose the packaged items to moisture. In addition, you can choose cross-linked polyethylene alternatives which have high aesthetic value.

Antistatic Polyethylene

Antistatic foam is suitable for creating case inserts for goods that are sensitive to static electricity. For example, electronic components which are used in most devices and equipment can be damaged by ambient static. This type of polyethylene foam is able to negate electrical charges in the case inserts so it will protect the products. Typically, the packaging material has a pink appearance but you should make special inquiries from your suppliers. The inserts are also dense so they can hold goods of considerable weight. Additionally, the antistatic foam has a closed cell structure so it does not allow free flow of air and moisture in the material.

Storing my family heirlooms

After my parents passed away I inherited a lot of bulky furniture items that have been in my family for many generations. My current inner city flat is nowhere near big enough for it so I rented out a storage unit. Sometimes I head out to the storage lot just to look through it and remember them. Luckily the furniture has stayed in great condition and one day when I finally get a big family home, I'll be able to have it all on display. I spent a lot of time researching the best way to store vintage furniture long term, and it's all on my site. Enjoy!
