What is the best type of foam for a custom plastic carrying case? It is impossible to answer this question because it is highly specific to the person that needs the case. Custom carrying cases are designed to be highly specific to the needs of those carrying the cases. The first step of the blow molded case construction process is determining what is carried in the case. Everything has a home within the case. With that in mind, knowing the different types of foam used for these cases is often helpful.
One of the most commonly used options is polyurethane foam. This foam is used in most standard cases because it is soft enough to be flexible but also dense enough to provide protection. The closest comparison to this material would be a sponge used to clean dishes.
Polyethylene foam is another standard option. It is often used to hold heavy parts. This type of foam holds large and heavy objects without collapsing. This material is more like a pool noodle than a sponge. Light objects do not work well with this type of foam.
Anti-static polyethylene foam is highly specific in its application, which is why it is often not used very much. It is ideal for parts that any ambient static electricity can damage. People often use this type of foam within the electronics industry because the foam can negate electrical charges that could potentially shock items.
Regardless of the type of foam you pick, you should ensure that it is highly specific to your needs. This will help you get the best possible carrying case with foam.
Stock cases work, but they do not meet the same protection standards of a custom plastic carrying case.
