Molded paper pulp, which is also called molded fiber, has been used since the 1930s to make containers, trays and other packages. Molded pulp packaging experienced a decline in the 1970s after the introduction of plastic foam packaging. But more recently the use of molded pulp packaging is growing because it fits in well with today’s emphasis on environmental friendliness and sustainability. Paper pulp can be produced from old newsprint, corrugated boxes and other plant fibers. Today, molded pulp packaging is widely used for electronics, household goods, automotive parts and medical products. It is also used as an edge protector or pallet tray for many shipping and handling applications.
