The Polyethylene Terephthalate, PET, is a transparent, light and strong plastic of the polyester family. It performs the dual position of polyester when used with materials 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.
Nevertheless, more than 60% of PET production takes place for synthesizing fibers and bottles account for only 30% of the global demand. Within the textile trade, PET is called as the polyester.
Number of PET colors and their makes use of in plastic manufacturing
The demand for PET products has elevated significantly over the years. For commercial success, corporations demand totally different colors to meet the expectation of consumers in the market. Thus, firms involved in making polymer compounds have created the following colour options and grades for users:
PET white
This white PET is suitable for dairy and other packaging applications in the industry.
PET Blue
Colorants must pass safety commonplace or FDA approval to use in packaging meals products. The PET blue is without doubt one of the hottest colors used within the water bottle packaging widely around the globe.
PET Amber
This colour is suitable for manufacturing PET bottles which demand to forestall UV rays from reaching inside. That’s because the packaged products get decontaminated and used in oil and pharma product packaging.
PET Yellow
When it involves packaging pesticide and chemical substances, 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 superb UV stabilizer used within the packaging industry. Unlike different stabilizers, it protects bottles as well its content material preventing the passage of rays. Hence, it eliminates the need to have an exterior packing on the bottles. Thus, it turns into a practical selection for any company involved in plastic bottle manufacturing.
