17 May Key details to know about Polyethylene Terephthalate
The Polyethylene Terephthalate, PET, is a transparent, light and robust plastic of the polyester family. It performs the dual position of polyester when used with materials and as a PET resin when it involves 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 fabricate 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 worldwide demand. Within the textile industry, PET is called as the polyester.
Number of PET colors and their uses in plastic manufacturing
The demand for PET products has elevated significantly over the years. For commercial success, firms demand completely different colors to meet the expectation of consumers within the market. Thus, companies involved in making polymer compounds have created the following shade options and grades for users:
This white PET is suitable for dairy and different packaging applications in the industry.
Colorants need to pass safety commonplace or FDA approval to make use of in packaging foods products. The PET blue is without doubt one of the hottest colors used within the water bottle packaging widely across the globe.
This shade is suitable for manufacturing PET bottles which demand to stop UV rays from reaching inside. That is because the packaged products get decontaminated and utilized in oil and pharma product packaging.
When it comes to packaging pesticide and chemical compounds, PET yellow is the best choice. That’s because it is non-reactive with many of the chemical substances used within 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 exterior packing on the bottles. Thus, it turns into a practical alternative for any firm involved in plastic bottle manufacturing.
