Advantages and Disadvantages of PET Resin
Polyethylene terephthalate offers a wide range of applications, especially in the packaging sector. PET resins are commonly used in manufacturing bottles, containers and packaging tapes. It proves to be an excellent barrier material, preventing the transfer of chemicals which makes it most suitable for food and cosmetics industry. PET resin is commonly used thermoplastics as it offers many benefits such as:
The polymers are easily available and inexpensive
PET polymers are highly resistant to moisture and chemical resistant to organic material and water.
It has a high strength to weight ratio.
It is highly transparent and shatterproof (it will not break like glass packaging).
PET materials come in a variety of shapes and colors which offer o good choice in producing attractive products.
Polyethylene terephthalate can be easily recycled. PET plastic is one of the most recycled plastics and they are reused to make products such as containers, sleeping bag insulation, polyester fabrics and carpets etc.
Though Polyethylene terephthalate is the maximum used thermoplastic and is used almost in every plastic products which are used in our daily lives, these polymers still have certain limitations such as:
As compared to other polymers PET polymer has lower heat resistance.
PET resins are even susceptible to oxidation. As for example, they are not used for storing beer or wine as the shelf life of these beverages is long such that some kind of taste degradation may occur.
PET plastics are not biodegradable which might be good or bad depending on their usage.
