How is PET Different from Other Plastic Types

There's no denying that plastic plays a significant role in the manufacturing and packaging industry. Its versatility enables it to be moulded into different shapes and sizes, alongside many other useful properties. 

However, as the world continues to take action against the global environmental impact of plastic, many companies are revising their operations to implement sustainable practices. At Petainer, we provide innovative packaging solutions that are specifically designed to fit into the circular economy. Our products are designed to be recycled, to reduce waste leaking into the environment. 

PET plastic is a sustainable packaging option and the leading type of plastic used for beverage bottles, owing to its excellent chemical resistance to organic materials and water, and high strength to weight ratio. Here we are going to explore what exactly PET bottles are, assess their benefits, and compare them to other plastic types.

What is PET?

PET, polyethylene terephthalate (also known as PETE) is a strong, stiff synthetic material that is part of the thermoplastics family, meaning it can be heated, melted and cooled into many shapes and sizes. Made from a combination of oils and petrochemicals, it's popular within the manufacturing sector for producing bottles and jars. In fact, almost every plastic bottle is made from PET. It's suitable for a range of beverages including carbonated, still and dilutable drinks, fruit juices, and bottled water. 

The material offers a protective barrier against CO2 and light, repels microorganisms and is EU/NSF/FDA tested and approved. PET is lightweight, can have a very clear appearance and looks similar to glass once set. It's strong, non-reactive and shatterproof, which allows the material to achieve high safety standards for food, drink and personal care products. It is so strong, that it can undergo HPP - high pressure processing - a heat free form of pasteurisation.
