The Polyethylene Terephthalate, PET, is a clear, light and strong plastic of the polyester family. It performs the dual role of polyester when used with materials and as a PET resin when it comes to manufacturing bottles, containers and packaging solutions.
How is PET made?
The polyester polymer is manufactured by reacting of ethylene glycol and terephthalic acid. The pellet polymer formed in the process is heated to molten mass to mold into completely different shapes. This property has helped to manufacture plastic water bottles and fibers to extend industrial applications.
However, more than 60% of PET production takes place for synthesizing fibers and bottles account for only 30% of the global demand. Within the textile trade, PET is called as the polyester.
Variety of PET colors and their uses in plastic manufacturing
The demand for PET products has increased significantly over the years. For commercial success, companies demand completely different colors to satisfy the expectation of consumers within the market. Thus, companies involved in making polymer compounds have created the next coloration options and grades for users:
This white PET is suitable for dairy and different packaging applications in the industry.
Colorants have to pass safety commonplace or FDA approval to make use of in packaging foods products. The PET blue is one of the most popular colors used in the water bottle packaging widely around the globe.
This colour is suitable for manufacturing PET bottles which demand to stop UV rays from reaching inside. That’s because the packaged products get decontaminated and used in oil and pharma product packaging.
When it involves packaging pesticide and chemical compounds, PET yellow is the very best choice. That’s because it is non-reactive with a lot of the chemical compounds used in the industry.
UvNox — shelf (PET)
PET is a superb UV stabilizer used within the packaging industry. Unlike different stabilizers, it protects bottles as well its content preventing the passage of rays. Therefore, it eliminates the necessity to have an external packing on the bottles. Thus, it turns into a practical alternative for any firm concerned in plastic bottle manufacturing.
