Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept:
Fibrous packaging materials can be manufactured as flat sheets or molded directly into three-dimensional shapes.
Molding directly from a fiber slurry allows the production of custom, protective shapes for fragile food items.
Step 2: Detailed Explanation:
Let us examine the listed packaging articles:
- Folding box board and Corrugated fiber board: These are manufactured as flat sheets on traditional paper machines and then cut, creased, and folded into boxes.
- Solid fiber drum: A cylindrical container wound from flat paperboard sheets.
- Molded pulp containers: These are produced directly from an aqueous slurry of recycled paper fibers or virgin wood pulp.
The slurry is drawn onto a mesh screen mold using a vacuum, which removes most of the water.
The formed wet pulp is then pressed and dried into its final three-dimensional shape, such as egg trays, cup carriers, and protective food trays.
This process allows the production of complex, discrete 3D shapes directly from a fiber suspension.
Therefore, molded pulp containers fit this description.
Step 3: Final Answer
The correct option is (C).
