Friedrich Pries, the founder of a company in Hamburg, Germany, used waste paper and starch as raw materials to make foam fillers for packaging that could be quickly decomposed by microorganisms and fungi after being discarded.
For a long time, most of the packaging of fragile products uses styrene porous plastic, which is made into small balls or flocs, scattered or lined in the packaging box to reduce the impact of external forces. However, the synthesis of styrene consumes not only the non-renewable raw material—petroleum—but also produces gas harmful to the earth's ozone layer during production. At the same time, this packing material cannot be degraded and will accumulate in nature for a long time. Packaging foam packing made of waste paper and starch avoids these problems.
Friedrich Pries made packaging foam fillers from waste paper and starch by cutting or crushing waste paper or inferior paper into fine powder, grinding it into unique fibers, and blending it with starch. The slurry is then pressed into granules, placed in a sealed vessel, subjected to high pressure and superheated steam, and then depressurized rapidly to expand the granules into a foam and form porous pellets. The replacement of styrene with this small ball as a packing foam filler can also withstand collisions and its function is better than styrene.
The use of this type of waste paper and starch packaging foam filler not only costs less than styrene but also does not adversely affect the environment.
