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 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 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 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, corporations demand totally different colors to satisfy the expectation of consumers in the market. Thus, companies involved in making polymer compounds have created the following colour options and grades for customers:
This white PET is suitable for dairy and other packaging applications in the industry.
Colorants must pass safety standard or FDA approval to use in packaging foods products. The PET blue is one of the hottest colours used within the water bottle packaging widely across the globe.
This coloration is suitable for manufacturing PET bottles which demand to stop UV rays from reaching inside. That's because the packaged products get decontaminated and used in oil and pharma product packaging.
When it comes to packaging pesticide and chemical compounds, PET yellow is the perfect choice. That’s because it is non-reactive with most of the chemicals used within the industry.
UvNox — shelf (PET)
PET is a wonderful UV stabilizer used within the packaging industry. Unlike different stabilizers, it protects bottles as well its content material stopping the passage of rays. Hence, it eliminates the necessity to have an exterior packing on the bottles. Thus, it turns into a practical choice for any company concerned in plastic bottle manufacturing.
