What is the melting point of thermoplastics?
The melting point of thermoplastics depends on the particular type of thermoplastics. The melting point varies from 160 Degrees Celsius to 350 Degrees Celsius for engineering thermoplastics. When it comes to high temperature thermoplastics, the melting point varies from 3593 to 4010 Degrees Celsius.

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.

What kind of Plastics are Thermoplastics?
Thermoplastics are plastics that can be melted and recycled. Thermoplastics are used for many objects such as bottles, bags, records, hoses, clothes, containers, etc. There are a variety of different types thermoplastics and can have many different qualities to combat the environment. They are different from "thermosetting" plastics in this way. Thermosetting plastics are typically heated and compressed in a mold to achieve a desired shape or mixed from a resin and a hardener as used for composite material. When they are in contact with high temperatures they burn instead of melt, which is why they cannot be recycled. They are generally used for kitchen utensils like a spatula but are often used for telephones, computers etc. Thermoplastics: ABS Vinyl PETE PP PE HDPE Polyester PS Thermosetting plastics: Vulcanized rubber Bakelite Duroplast Urea-formaldehyde Melamine resin Epoxy resin Polyimides
