If you are thinking to make clear plastic packaging for your design, one of the most common question you might have is what material should I use? Should I use PVC or PET?
Here we will talk about 13 reasons that why PET is better than PVC, such as durability, price, transparency, weight and so on. We will also discuss some of the disadvantage of PET and the most asked questions about PET: Is PET toxic? Can PET be reused? Will PET cause cancer?
What is PET
Polyethylene terephthalate (PET) is the most common thermoplastic resin of the polyester family. It is widely used for fiber production in clothing, containers for liquids and food items, and thermoforming for manufacturing.
The use of PET is very extensive in making bottles and containers for packaging liquid and food products. Its features make it ideal for being used in packaging food items. It is a very strong material and inert which does not react with food and beverages.
It is resistant to attacks by micro-organisms, is lightweight, easy to transport, and also shatterproof. It is completely recyclable and is one of the most recycled plastic globally.
Europe has a PET recycling rate of 52% and the US has 31%. Considering these properties, PET is a cost-effective, environmentally friendly, and sustainable product for packaging.
What is PET Made From
PET was first developed for use in synthetic fibers by British Calico Printers in 1941. The patent rights were then sold to DuPont and ICI. Ethyl glycol and terephthalic acid are the building blocks of PET, which combine together to form a polymer chain.
The strands of PET are then extruded, quickly cooled, and cut into small pellets. These pellets are then heated which converts them into a molten liquid which can be easily molded into items of any shape and size.
The majority of the use of PET (more than 60%) is for production of synthetic fiber commonly known as nylon. Packaging accounts for about 30% of the global demand for PET.
What is PVC
Polyvinyl Chloride (PVC) is the world’s third-most widely used synthetic plastic polymer with about 40 million tons of annual production. It is made of 57% chlorine and 43% carbon.
PVC is made in two general forms- as rigid polymer and flexible plastic. It has a wide application and is used for manufacturing pipes, electric cables, signboards, clothing, flooring, and other construction works.
PVC is a dense plastic and cheap also. It is very hard, has extremely good tensile strength, and is resistant to chemicals and alkalies. It is toxic and can pose health hazards as when burnt, it emits hydrogen chloride (HCl) fumes.

Reasons PET is Better Than PVC
Some of the key reasons why PET is better than PVC are provided below:
Both PET and PVC have an oil base. One aspect where PET scores over PVC is its recycling abilities.
In the US, most municipal authorities do not accept PVC in the consumer recycling program. PET, on the other hand, is one of the most widely recycled plastics in the US and around the world. Overall, PET is eco-friendlier than PVC.
