Expanded polystyrene disappears faster than legislation requires
Bans on expanded polystyrene food packaging have taken effect across a growing number of jurisdictions, and the material is retreating from egg cartons considerably faster than those rules alone would explain. The reason is that moulded fibre was already winning on breakage and moisture management, so legislation removed a material that packers had limited reason to defend. Substitution has therefore been unusually smooth, without the cost or performance disputes that accompany most regulatory material transitions in packaging. Packers had limited reason to defend a material already losing on the measure they care about.
