Product Overview
Propack's vacuum forming capabilities produce precisely contoured ESD-safe trays, carriers, blisters, and clamshells from conductive and dissipative thermoplastic sheets. Unlike generic foam or PP boxes, vacuum-formed trays hold components in exact, defined positions — eliminating movement, contact between components, and the need for additional packing materials.
Materials offered include conductive PET (cPET), conductive HIPS, conductive ABS, and anti-static PS — each with defined surface resistivity for different EPA zone requirements. Trays are designed in-house using CAD from customer drawings or sample components, tooled in 7–10 business days, and batch-tested for dimensional accuracy, resistivity, and stacking stability before shipment.
Key Features
Precision Component Pockets
Each pocket is formed to ±0.3 mm of the component drawing. Components are held in positive registration — no movement, no contact between parts, no secondary packing material needed.
Stackable Design
Trays nest securely when empty for space-efficient return logistics and stack stably when loaded in 5–10 tier columns on standard Euro pallet footprints.
Multiple ESD Grades
Conductive (10³–10⁵ Ω), Dissipative (10⁵–10⁹ Ω), and Anti-Static (10⁹–10¹¹ Ω) materials to match your EPA zone and component CDM sensitivity levels.
Cleanroom Compatible
Available in ISO Class 6 cleanroom-produced grades with ultra-low outgassing, low particle generation, and cleanroom bagging — suitable for optical, medical, and defence electronic assemblies.
Transparent Lidding
Optional anti-static transparent PET or PS lid allows visual inspection of component orientation without opening the tray — reduces defect escape during receiving inspection.
Automation-Friendly
Tray geometry can be designed for robotic pick-and-place loading and unloading. Consistent pocket location tolerances (±0.3 mm) and flat base for vacuum gripper compatibility.

Applications
Custom Tray Development Process
- 1
Component Sample / Drawing
Send a component sample or 3D drawing (STEP/IGES). Our engineers design the pocket geometry with appropriate clearance for loading and unloading method (manual or robotic).
- 2
3D Tray Design & Review
We generate a 3D tray model for customer review within 3 business days. Stack height, nesting features, and label position are confirmed before tooling.
- 3
Tooling Manufacture
Aluminium vacuum-forming tool is machined in 5–7 days. Prototype samples are formed and sent for dimensional and resistivity verification.
- 4
Sample Approval
Customer approves production sample. Any pocket geometry amendments are implemented before first production batch is released.
- 5
Production & Supply
Production batches include a Certificate of Conformance with resistivity test results. Ongoing supply available from dedicated tooling held at our facility.
