Is resin expensive or plastic expensive?

Generally, the price of resin is more expensive than that of plastic.

Generally speaking, resin is more expensive than plastic. This is because resins are usually extracted from plants or animals, or made through complex synthetic processes. These processes not only need a lot of energy input, but also need high-level technical and equipment support, so the cost of resin is also very high. In contrast, plastics can be extracted from cheap fossil fuels and the production cost is lower.
