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 fabrics 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 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. Within the textile industry, PET is called because the polyester.
Number of PET colours and their makes use of in plastic manufacturing
The demand for PET products has increased significantly over the years. For commercial success, corporations demand totally different colors to fulfill the expectation of consumers within the market. Thus, companies concerned in making polymer compounds have created the next colour options and grades for customers:
This white PET is suitable for dairy and different packaging applications in the industry.
Colorants have to pass safety standard or FDA approval to make use of in packaging foods products. The PET blue is one of the hottest 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 comes to packaging pesticide and chemicals, PET yellow is the most effective 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 different stabilizers, it protects bottles as well its content stopping the passage of rays. Hence, it eliminates the need to have an external packing on the bottles. Thus, it becomes a practical choice for any company concerned in plastic bottle manufacturing.
