01 Start with the Electronic Component Tray Requirement

Anti-static trays are commonly used to hold connectors, sensors, PCB assemblies and other electronic components during storage, handling or transportation. The required protection depends on the sensitivity of the components and the customer’s handling process.

Before selecting a sheet, we recommend confirming three questions: Does the operator need to see the components through the tray? Will the tray be discarded after one use or handled repeatedly? What electrical resistance range must the formed tray meet?

These answers usually narrow the material options more effectively than requesting a general “ESD plastic sheet.” Appearance, service life and electrical performance should be considered together.

02 Choosing Anti-Static PET, PS/HIPS or PP

We generally divide electronic component tray projects into three practical purchasing situations. Each points toward a different starting material.

Transparent Inspection Trays — Anti-Static PET

When component visibility is important, anti-static PET is usually our first material to evaluate. Clear PET allows operators to inspect components while retaining the appearance expected from transparent thermoformed packaging.

Surface-coated PET is often a practical choice for disposable trays with a defined service period. For applications that require longer-term resistance stability, intrinsic anti-static PET can also be evaluated.

Opaque, High-Volume Trays — Anti-Static PS/HIPS

For opaque electronic component trays where material cost and rigidity are important, anti-static PS/HIPS is often the more economical starting point. It offers useful thermoforming characteristics for repeat-volume packaging applications.

Internal anti-static additives can meet many standard requirements. When longer-lasting performance or more demanding formed geometry is specified, permanent polymeric anti-static PS/HIPS deserves separate consideration.

Tough or Repeatedly Handled Trays — Anti-Static PP

Anti-static PP is worth evaluating when the tray needs greater toughness, flexibility or resistance to repeated handling. These requirements can make PP more suitable than a stiffer PS-based material.

For natural or white trays, permanent polymeric anti-static PP may also be an option when stable electrical performance is required. The choice should be justified by the actual handling conditions, rather than the assumption that permanent protection is always better.

03 Selecting the Anti-Static Technology

Choosing PET, PP or PS/HIPS is only the first step. Different anti-static technologies affect the service life, surface properties and electrical stability of the supplied sheet.

For reference, our available material options cover different electrical performance ranges. Coated anti-static PET is typically specified around 10⁸–10¹⁰ Ω, while internal anti-static PP/PS options are commonly specified around 10⁹–10¹¹ Ω. Permanent polymeric PP/PS options can be specified around 10⁷–10⁹ Ω.

Intrinsic anti-static PET is another option for projects prioritizing long-term performance. Its volume resistivity data must not be compared directly with surface resistance values. Buyers should confirm the test method, measurement conditions and required acceptance range for the selected grade.

We would generally recommend economical coated or internally modified materials where they meet the project requirements. Permanent systems become more attractive when service life, repeated handling or resistance stability justifies the additional material cost.

04 Anti-Static Performance After Thermoforming

For electronic component trays, electrical performance on the finished thermoformed part matters more than a flat-sheet measurement alone.

During forming, material stretches into cavities and around corners. The resulting changes in thickness and surface condition can affect the performance of some anti-static technologies, particularly in demanding forming applications.

This is an important distinction between a general material specification and a tray-specific purchasing decision. A sheet may meet the agreed resistance range before forming, but the customer still needs to confirm acceptable performance on representative areas of the formed tray.

Permanent polymeric anti-static PP/PS can be particularly useful for deep or complex trays where stable post-forming resistance is a priority. However, even permanent grades should be approved through actual forming trials.

05 Sheet Thickness, Width and Roll Supply

A suitable anti-static specification must also provide the rigidity and forming performance required by the tray. Sheet thickness should be selected according to tray dimensions, cavity depth, component weight and expected handling conditions.

At DESU, we supply functional thermoforming sheet rolls with customized material, thickness, width, color and packing options according to the selected grade. For coated PET, the treated side and downstream processing requirements should also be confirmed.

Repeat production requires more than an approved material sample. Thickness consistency, winding quality and electrical performance between batches can influence the converter’s forming results and material acceptance.

06 Sample Approval Before Bulk Supply

Before changing anti-static sheet suppliers or introducing a new tray, we recommend testing the selected material under representative forming and handling conditions.

The trial should confirm appearance, formed-part rigidity and electrical performance. Projects involving repeated handling or extended storage should also evaluate resistance stability over the expected service period.

Providing an existing sheet specification or tray sample helps us narrow the material options and review practical supply requirements. This is more effective than requesting an anti-static grade based only on a general resistance number.
