Answer:

The polythene bag melts down when a little HEAT is applied

Explanation:

Polythene:

Any different light thermoplastic materials produced using ethylene with properties relying upon the atomic load of the polymer. The normal structures are a waxy adaptable plastic (low-thickness polythene) and a harder inflexible more translucent structure ( high-thickness polyethylene). Polythene is utilized for bundling, shaped articles, lines and tubing, protection, materials, and coatings on metal. Polyethylene or polythene is the most usually created plastic. It is a polymer, essentially utilized for bundling. Starting around 2017, north of 100 million tons of polyethylene reins are being created every year, representing 34% of the all-out plastics market.
