3 Ways Molded Fiber Containers Are Processed

Consumers more and more prefer to patron businesses that use sustainable, environmentally friendly options. That is why molded fiber containers have become popular options. They use all natural processes with 100 percent recycled raw materials that also are easily composted or recycled once they are used. Companies benefit from protected and secure packaging that remains eco-friendly. It is beneficial to learn more about the production process before you place an order for your business.

Different Types of Molded Fiber Products

There are four main types of molded fiber products. Type 1 utilizes one mold that has walls about 3/16 to 3/8 inch thick. It is typically used to package heavy, non-fragile items. Type-2 has one forming mold and also uses a transfer mold for products. This type has a wall thickness ranging from 1/8 to 3/16 inches. This generally is used for creating egg cartons and molded fiber food tray. Type-3 incorporates smaller wall thickness ranging from 3/32 to 5/32 inches. Type-4 requires additional treatment beyond just the mold.

Traditional

The traditional way that companies create type 2 molded fiber containers begins by combining recycled fibers and water. Through using an industry-standard vat that performs similarly to a blender, the items are mixed until the mixture becomes a slurry-like texture. Then, the slurry is moved to the forming station where a vacuum pushes the slurry through. A screen traps the fibers while the water is recycled to be used again. The fibers are put into a mold and transferred to an oven, where they come out dry and ready to go. They are formed to the specifications of the client.

Thermoformed

Thermoformed processing manufactures type 3 molded fiber containers. The process begins in the same way as the traditional process with the fibers and water slurry produced. Then, the slurry moves into an area to form the product. Once the fibers are removed from the water onto a screen, the equipment presses them into molds based on the design of the product. Then, any remaining water is removed using pressure and heat rather than an oven.

Pressed Traditional

Another alternative for type 2 molded fiber containers is the pressed traditional. The process and equipment are the same as the traditional processing method at the start. However, rather than going to a conventional oven, the materials go to an automated pressing station. This process provides an improved dimensional tolerance and surface finish, which is why many businesses choose this rather than the traditional style.

By recognizing the different options for processing and creating molded fiber packaging, you can better choose the right ones for your business. You can also talk with your contact at the molded fiber production plant to determine the right solution for your needs.
