In the first part of this series, I described five general types of void fill –

1. Loose fill materials
2. Industrial papers
3. Flexible foams and bubble material
4. Expandable foam
5. 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.

Surface protection. 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.

Dust free. 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. (more…)

Some types of secondary packaging material are far worse for the environment than others. One of the worst, in our opinion, is the old standby for void fill, polystyrene loose fill. Folks who use this material because of its (perceived) low cost and (real) speed, are, well … ecoblivious.

Polystyrene is recyclable, but not easily so. The material is extremely lightweight and therefore expensive to ship to recycling centers, which are often a long distance away. While associated transportation costs have always been high, the economics are now even worse due to the rapid run up in fuel costs. (more…)
