Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept:
Cellulose-based packaging materials can be processed into various shapes and configurations.
Different manufacturing processes yield distinct structures, ranging from flat sheets to three-dimensional structures.
Step 2: Detailed Explanation:
Let us analyze the given packaging forms:
- (A) Folding carton: Manufactured from flat sheets of paperboard that are creased, folded, and glued.
- (B) Beverage carton: A laminate of paperboard, polyethylene, and aluminium foil used for liquid packaging.
- (C) Vegetable parchment: A flat, grease-resistant paper treated with sulfuric acid.
- (D) Moulded pulp (or molded fiber): This packaging is made from recycled paperboard and/or wood pulp slurry.
During manufacturing, the slurry of cellulosic fibers is drawn onto screened molds using vacuum, forming a three-dimensional shape.
It is then dried to create discrete products like egg trays, food service trays, and protective packaging inserts.
Therefore, the description matches Moulded pulp.
Step 3: Final Answer:
The packaging form described is Moulded pulp.
