The Polyethylene Terephthalate, PET, is a transparent, light and strong plastic of the polyester family. It performs the twin role 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 manufacture plastic water bottles and fibers to extend industrial applications.
Nonetheless, more than 60% of PET production takes place for synthesizing fibers and bottles account for only 30% of the worldwide demand. Within the textile business, PET is called because the polyester.
Variety 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 different colors to fulfill the expectation of consumers within the market. Thus, companies involved in making polymer compounds have created the next color options and grades for users:
This white PET is suitable for dairy and different packaging applications within the industry.
Colorants have to pass safety standard or FDA approval to make use of in packaging foods products. The PET blue is among 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 prevent 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 chemicals, PET yellow is the most effective choice. That’s because it is non-reactive with many of the chemical substances used in 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 material stopping the passage of rays. Hence, it eliminates the need to have an exterior packing on the bottles. Thus, it becomes a practical choice for any firm involved in plastic bottle manufacturing.
