PET: Learn about this common plastic

PET plastic is widely used in various fields such as food and beverage packaging, fiber products, etc. 

PET is a thermoplastic with good transparency, toughness and high temperature resistance. This makes it one of the most common materials used in the packaging industry. PET plastic can also be prepared through polymerization. This preparation method is relatively simple and reduces production costs.

However, while PET plastic excels in many ways, it also poses some sustainability challenges. The first is the issue of plastic pollution. PET plastic is difficult to decompose naturally and therefore becomes one of the main plastic wastes in the marine and terrestrial environments. Secondly, the production process of PET requires a large amount of energy and chemicals, which puts a certain amount of pressure on the environment. We need to face these challenges together and find ways to reduce the use of PET plastic.

Next, let’s explore how to reduce the use of PET plastic. One way is to look for alternative materials. Biodegradable plastics are a promising alternative that can break down into harmless substances under certain conditions. For example, starch-based degradable plastics and polylactic acid plastics are common degradable materials that are widely used in food packaging and disposable products. In addition, there are some recyclable alternatives, such as Polyethylene Terephthalate Glycol (PETG), which has similar properties to PET but is easier to recycle.

In addition, recycling and reuse are also important measures to reduce PET plastic pollution. We can actively participate in activities to recycle PET plastic and ensure that discarded PET plastic is properly processed and recycled. At the same time, the government and relevant institutions should also increase support and investment in the plastic recycling and recycling industry.
