Polythene.

Aluminium and Titanium Extruded polystyrene is about as strong as unalloyed aluminium, but much more flexible and much lighter.
Bakelite is a thermosetting plastic, meaning it cannot be reshaped once molded, while polythene is a thermoplastic that can be melted and reshaped multiple times. Bakelite is a poor conductor of electricity, whereas polythene is an insulator. Bakelite is more rigid and heat resistant compared to polythene.
pure aluminium is very soft and it is ductile (flexible)
the aluminium wire was as powerful as a king.
Polythene feels smooth and slightly waxy to the touch. It is a durable and flexible material commonly used in packaging and construction due to its strength and water-resistant properties.
Aluminium is used to make tin foil because it is lightweight, flexible, and resists corrosion. Steel, on the other hand, is heavier, less flexible, and prone to rusting. Aluminum's properties make it more suitable for food packaging and cooking applications than steel.
Garbage bags are flexible due to them being made from specially structured hydrocarbons known as polyethene or (polythene) as we call it. In certain cases plasticisers can also be added to a material to make it more flexible. NOTE: Polyethene is a large polymer which is a long giant lattice of small individual monomers.
The main difference between Ordinary Polythene & Biodegradable polythene is: * Ordinary polythene takes an around 100 + years to degrade... * Biodegradable/Degradable polythene degrades or biodegrades in around 5 yrs depending on how it's made and how its disposed. However, biodegradation starts in the presence of sunlight, moisture, mechanical stress and/or microorganisms...

Polythene is a type of plastic that is non-biodegradable, meaning it does not break down easily in the environment. This has led to issues with pollution and waste management, as polythene items can persist in the environment for a long time. Efforts are being made to reduce the use of polythene and find more sustainable alternatives.
because it is a light metal that is very flexible (for cabin compression) and strong.
