In the first part of this series, I described five general types of void fill --
- Loose fill materials
- Industrial papers
- Flexible foams and bubble material
- Expandable foam
- Inflatable air pillows
Now let's look at the qualities you may need from your void fill material, and see how the various options stack up.
For glass, metal, and scratch-sensitive plastics, polypropylene (PP) foams are the least abrasive option, followed by polyethylene (PE) foams and bubble. Industrial papers, depending on the grade, may also work.
Loose fill, whether polystyrene or one of the various biodegradable varieties, are prone to flaking. Industrial papers sometimes contain dust as a result of the trimming process. For shipping things such as pharmaceutical or personal health care products, look in other directions for void fill.
