17 May Key facts to know about Polyethylene Terephthalate
The Polyethylene Terephthalate, PET, is a transparent, light and strong plastic of the polyester family. It performs the dual role 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 within 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.
Nonetheless, 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 as the polyester.
Variety 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 satisfy the expectation of consumers in the market. Thus, companies concerned in making polymer compounds have created the next shade options and grades for users:
This white PET is suitable for dairy and different packaging applications within the industry.
Colorants need to pass safety customary 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 color is suitable for manufacturing PET bottles which demand to stop UV rays from reaching inside. That’s because the packaged products get decontaminated and utilized in oil and pharma product packaging.
When it involves packaging pesticide and chemical substances, PET yellow is the best choice. That’s because it is non-reactive with many of the chemical compounds 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 preventing the passage of rays. Hence, it eliminates the necessity to have an exterior packing on the bottles. Thus, it becomes a practical choice for any firm involved in plastic bottle manufacturing.
