Molded fiber products, manufactured with waste paper or other natural fibers (which are essentially cellulose) and are recyclable along with other waste paper are biodegradable, and compostable where facilities are available. They can also be incinerated without damaging incinerators.
Both fiber & water are recycled and reused in manufacturing, resulting in almost zero waste. There are no toxic or hazardous waste materials expelled into the environment.
The Four Basic Types of Molded Fiber Products
Type-1 Thick-Wall
Type-2 Transfer
Type-3 Thermoformed (Thin-wall)
Type-4 Processed
| Type-1 Molded Fiber Products - Thick Wall
Manufactured using a single mold with product wall thickness from 3/16 to 3/8 inches. One surfaces is relatively smooth, with one side rough. Primarily used for support packaging of non- fragile, heavier items. (vehicle parts; furniture, motors etc.). As well as, plant, floral and nursery pots and containers. Oven dried. | |
| | Type-2 Molded Fiber Products - Transfer Molded
Manufactured using one forming mold and one transfer mold with product wall thickness from 1/8 to 3/16 inches. Surfaces are relatively smooth on one side. Most common use is for egg cartons and trays. New designs are used for many types of electronic product packaging such as cell phones, DVD players etc. Also, used for hospital disposables, electrical appliances, office equipment, tableware and fruit and drink trays. Oven dried. | |
| Type-3 Molded Fiber Products - Thermoformed
(Sometimes called "thin-wall")
Manufactured using multiple heated molds with product wall thickness of 3/32 to 5/32 inches. Surfaces are smooth and forms are well detailed with minimal draft angles. Products are dried in the mold and no oven curing is needed. Due to the hot mold pressing process, the walls are somewhat more dense. Type-3 thermoformed fiber, products closely resemble Thermoformed plastic material. | |
| | Type-4 Molded Fiber Products - Processed This type is refers to molded fiber products that require some type of secondary or special
treatment other than simply being molded and cured. Examples are:
- Hot or after pressed - Die-cut or perforated - Printed - Colored - Special mold
- Special slurry formulations -Embossments - Special design features - Special additives | |
