Plastics have stronger bonds between the polymer chains-these

might be covalent bonds between the chains, or cross-linking bridges. These plastics have a higher melting point, are rigid and can't be stretched, as the cross-links hold the chains firmly together.

Hope i helped :-)

Plastic is made up of long molecules that are tightly packed together, making it a highly rigid and inflexible material. When a force is applied to stretch it, the molecules resist movement, causing the plastic to break rather than stretch. Additionally, the molecular structure of plastic lacks the elasticity of materials like rubber, further limiting its ability to be stretched.
