High speed equipment is available to set-up, load, and close the cartons.
Egg Carton

Traditionally these have been made of molded pulp. This uses recycled newsprint which is molded into a shape which protects the eggs.
More recently egg cartons have also be made from expanded polystyrene (styrofoam) and PET.
