Molded fiber, also known as paper pulp is a common packaging material used in many consumer applications, such as egg cartons, beverage carriers and protective product packaging. Because molded fiber is produced from recycled paper or fiber, it is 100 percent recyclable and biodegradable, making it an environmentally friendly alternative to plastic packaging.
The production of paper pulp packaging is an automated, quick and low-cost manufacturing process. A mixture is made from ground recycled paper or fiber dissolved in water. Then a mold is dipped into the slurry and a vacuum on the backside pulls the slurry onto the mold to form the shape of the package. Type two molded pulp manufacturing involves another step, transferring the piece to a second mold on the opposite side, which is suctioned by an additional vacuum. Then the piece is ejected from the mold and placed in a drying oven.
