Final answer:
Parachute packing paddles require durable and pliable materials, and items like take-out trays or foam packaging peanuts are not suitable due to their lack of strength and durability.
Step-by-step explanation:
The parachute packing paddle should be made from a material that is both strong and pliable, but there are certain materials that would not be suitable for its construction. Typically, materials like take-out trays, foam packaging peanuts, CD cases, foam-walled drink cups, and other thin-walled and moldable parts are not appropriate for a parachute packing paddle. These materials are often too flimsy, not durable enough, and lack the necessary strength and pliability needed for the repeated and reliable packing of a parachute.
The parachute packing paddle can be made out of any suitable strong and pliable material except for foam-walled drink cups, CD cases, and other thin-walled and moldable parts.
