Key Requirements for Electronic Inner Tray Materials
When selecting materials, the first thing to do is to clarify the tray for packaging electronic products, which must have the following properties:
Stable rigidity and structural support: Avoid tray deformation, warping or collapse during stacking and mass storage.
Excellent impact and compression resistance: Prevent precision electronic parts from vibration damage, scratching and cracking during logistics.
High dimensional stability: Low shrinkage rate to ensure precise groove positioning and consistent batch size.
Smooth and dust-free surface: No impurities, scratches or dust contamination to protect sensitive electronic components.
Good thermoforming performance: Adapt to vacuum forming and deep drawing for customized groove shapes.
Optional anti-static function: Prevent static electricity from damaging microchips and circuit boards.
Top 3 Best Plastic Sheets for Electronic Inner Trays
1.White APET Rigid Sheet
White APET sheet is the most widely used material for standard electronic inner trays, recognized for its balanced performance and high cost performance. It features high rigidity, uniform thickness, and smooth opaque surface that effectively covers and protects internal electronic parts from light and dust.
Advantages: High structural stability, no deformation after forming, excellent die-cutting and thermoforming performance, no folding whitening, stable batch consistency, and eco-friendly recyclable. It is clean, odorless, and suitable for mass production of daily electronic component trays.
Best for: Ordinary circuit board trays, accessory sorting trays, consumer electronics inner supports, and general hardware component packaging.
2.HIPS Sheet
HIPS (High Impact Polystyrene) sheet is a classic industrial packaging material with outstanding hardness and strong compression resistance. It features good moldability, flat surface, and stable mechanical strength, making it ideal for thick and supportive electronic trays.
Advantages: Super high rigidity, strong stacking resistance, low cost, easy thermoforming and customized shaping. It is not easy to deform under long-term stacking pressure.
Best for: Thick electronic trays, heavy component packaging, industrial batch storage trays, and high-stacking packaging scenarios.
3.GAG Sheet
As a three-layer composite (APET+PETG+APET) high-performance sheet, GAG sheet upgrades the defects of single-layer PET materials. It integrates high toughness, low temperature resistance, zero folding whitening and ultra-high forming accuracy.
Advantages: Excellent deep drawing performance, ultra-low shrinkage rate, no cracking during complex forming, flawless surface after bending, and strong anti-drop performance. It maintains stable performance even in low-temperature storage environments.
Best for: High-precision chips, fragile electronic parts, high-end digital product inner trays, and export-grade electronic packaging.
Why Custom Plastic Sheets Are Better for Electronic Trays
Standard fixed-size trays cannot meet personalized groove spacing, depth and structural requirements of different electronic parts. Custom thermoforming plastic sheets support customized thickness, hardness, color and anti-static treatment. Professional customized sheets ensure perfect fitting of electronic parts, avoid shaking and scratching, and greatly improve packaging efficiency and product safety.
