The Polyethylene Terephthalate, PET, is a transparent, light and sturdy plastic of the polyester family. It performs the dual 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 within the process is heated to molten mass to mold into totally different shapes. This property has helped to fabricate 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 global demand. Within the textile industry, PET is called as the polyester.
Variety of PET colors and their makes use of in plastic manufacturing
The demand for PET products has increased significantly over the years. For commercial success, companies 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 customers:
PET white
This white PET is suitable for dairy and other packaging applications in the industry.
PET Blue
Colorants have to pass safety customary or FDA approval to make use of in packaging foods products. The PET blue is one of the most popular colours used in the water bottle packaging widely across the globe.
PET Amber
This shade 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.
PET Yellow
When it comes to packaging pesticide and chemicals, PET yellow is the best choice. That’s because it is non-reactive with most of the chemical compounds used in the industry.
UvNox — shelf (PET)
PET is a wonderful UV stabilizer used within the packaging industry. Unlike other stabilizers, it protects bottles as well its content preventing the passage of rays. Hence, it eliminates the necessity to have an external packing on the bottles. Thus, it turns into a practical selection for any firm concerned in plastic bottle manufacturing.
