PET (polyethylene terephthalate) plastic sheet is often chosen for ESD (electrostatic discharge) antistatic electronic parts packing because it has several beneficial properties:

Antistatic properties: PET plastic can be made antistatic by adding special additives that help to dissipate any static charge that may build up on the surface of the material. This makes it an ideal material for packaging electronic components that are sensitive to electrostatic discharge.

Transparent: PET plastic is clear and transparent, which allows for easy identification of the contents inside the packaging without having to open it. This is important for electronic components that need to be tracked and identified throughout the manufacturing and shipping process.

Lightweight: PET plastic is lightweight and flexible, which makes it easy to handle and transport. This is important for electronic components that may be fragile and need to be handled carefully.

Durable: PET plastic is strong and durable, which helps to protect the electronic components during shipping and handling. This is important for components that may be sensitive to damage from vibration, impact, or other environmental factors.

Cost-effective: PET plastic is relatively inexpensive compared to other materials used for electronic component packaging, which helps to keep the overall cost of the product down.

Overall, PET plastic sheet is an excellent choice for ESD antistatic electronic parts packing due to its antistatic properties, transparency, lightweight, durability, and cost-effectiveness.
