The Polyethylene Terephthalate, PET, is a clear, light and robust plastic of the polyester family. It performs the twin position 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 within 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 increase industrial applications.
Nevertheless, more than 60% of PET production takes place for synthesizing fibers and bottles account for only 30% of the worldwide demand. In the textile trade, PET is called because the polyester.
Number of PET colors and their uses in plastic manufacturing
The demand for PET products has increased significantly over the years. For commercial success, corporations demand totally different colors to meet the expectation of consumers in the market. Thus, companies concerned 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 must pass safety commonplace or FDA approval to make use of in packaging meals products. The PET blue is without doubt one of the most popular colours used within the water bottle packaging widely across the globe.
This colour is suitable for manufacturing PET bottles which demand to forestall UV rays from reaching inside. That is because the packaged products get decontaminated and used in oil and pharma product packaging.
When it involves packaging pesticide and chemicals, PET yellow is the best choice. That’s because it is non-reactive with most of the chemical compounds used within the industry.
UvNox — shelf (PET)
PET is a superb UV stabilizer used in the packaging industry. Unlike other stabilizers, it protects bottles as well its content material preventing the passage of rays. Therefore, it eliminates the necessity to have an exterior packing on the bottles. Thus, it becomes a practical alternative for any company concerned in plastic bottle manufacturing.
