Why are thermoplastics used for packaging?
Thermoplastics are used for packaging because they can be softened and reshaped as many times as the material can take. This is good, because then they can be recycled and the plastic can be used again. Thermosetting plastics however, can only be shaped once, as the polymers bond together and are inseparable. This would mean for every piece of packaging more plastic would have to be made, which would be very bad environmentally, as a lot of crude oil and other resources would need to be used up. This cannot be sustained, therefore, thermoplastics are used instead.
