APET Normal Carrier Tape material — also referred to as insulating-grade or non-dissipative APET carrier tape — is the highest-resistance variant within the APET carrier tape family, engineered for surface resistance values of ≥ 10¹² Ω. Unlike its conductive and anti-static counterparts, Normal grade carrier tape does not actively dissipate electrostatic charge; instead, it is manufactured for general-purpose component packaging, structural carriers, and applications where electrostatic discharge (ESD) sensitivity is not a primary concern. This guide explains the material science, technical specifications, manufacturing standards, and application logic behind APET Normal Carrier Tape, drawing on production data from Haining Hongkai Technology, an ISO 9001 & ISO 14001 certified APET, ABS, and HIPS sheet manufacturer based in Haining City, Zhejiang Province, China.
1. What Is APET Normal Carrier Tape Material?
Amorphous Polyethylene Terephthalate (APET) is produced by rapidly quenching molten PET resin after extrusion, which prevents the polymer chains from crystallizing. This quenching process yields a material with high optical clarity, dimensional stability, and excellent thermoformability — properties that crystalline PET (CPET) cannot replicate at room temperature.
APET Carrier Tape is a downstream product of this base resin, extruded and slit into precision-width rolls or sheets specifically for the packaging of integrated circuits (ICs), surface-mount devices (SMDs), passive components, and other items requiring dimensional consistency during automated handling. Within this product category, manufacturers typically offer three electrical grades distinguished by surface resistivity:
- Conductive grade — surface resistance of 10⁶–10⁸ Ω, for the most ESD-sensitive components.
- Anti-static grade — surface resistance of 10⁹–10¹¹ Ω, for standard SMD/IC packaging.
- Normal grade (this guide's subject) — surface resistance of ≥ 10¹² Ω, effectively electrically insulating, intended for components and structural packaging applications that are not ESD-sensitive.
Because Normal grade carrier tape contains no conductive or static-dissipative additive package, it retains the base resin's full optical clarity and generally offers the most cost-efficient option of the three grades — an important consideration for high-volume, non-sensitive packaging runs.
2. Technical Specifications — APET Normal Carrier Tape
The table below lists the standard production parameters for Normal grade carrier tape as manufactured by Haining Hongkai Technology. All figures represent factory-standard tolerances; tighter tolerances are available on request for high-precision applications.

| Property | Specification | Tolerance |
|---|---|---|
| Density | 1.35 g/cm³ | ± 0.02 g/cm³ |
| Thickness Range | 0.2 mm – 1.0 mm | ± 0.015 mm |
| Width Range | 12 mm – 640 mm | ± 1.0 mm |
| Maximum Roll Length | 1,150 m | ± 1 m |
| Surface Resistance | ≥ 10¹² Ω | Non-dissipative |
| Light Transmittance | ≥ 88 % | ASTM D1003 |
| Glass Transition Temp. (Tg) | ~75 – 80 °C | DSC method |
| Recommended Thermoforming Temp. | 130 – 160 °C | Process guideline |
Every roll is manufactured on Hongkai's dedicated extrusion lines, which produce a combined 700 tons of finished sheet per month, giving buyers confidence in consistent lot-to-lot uniformity for large or recurring orders.
3. Normal vs. Anti-Static vs. Conductive: Full Grade Comparison
Selecting the correct electrical grade is the single most important decision in APET carrier tape sourcing. The table below places Normal grade alongside its two counterparts so buyers can weigh protection level against cost and application fit.
Table 2 — APET Carrier Tape Grade Comparison
| Parameter | Conductive | Anti-Static | Normal |
|---|---|---|---|
| Surface Resistance (Ω) | 10⁶ – 10⁸ | 10⁹ – 10¹¹ | ≥ 10¹² |
| Static Behavior | Highly conductive | Moderately dissipative | Non-dissipative / insulating |
| Density | 1.35 g/cm³ | 1.35 g/cm³ | 1.35 g/cm³ |
| Thickness Range | 0.2 – 1.0 mm | 0.2 – 1.0 mm | 0.2 – 1.0 mm |
| Typical Application | High-density ICs, memory chips | Standard SMD/IC packaging | General component storage, non-ESD parts, structural carriers |
| Relative Cost | Highest | Medium | Most economical |
| Optical Clarity | Reduced (additive-dependent) | Slightly reduced | Maximum clarity (no additive package) |
Buyers should note that "Normal" does not mean lower quality — it means the material is engineered without a conductive additive package. For components with no ESD sensitivity rating, or for structural, cosmetic, and general industrial carrier applications, Normal grade delivers the same dimensional precision and thermoplastic performance as the conductive and anti-static variants, at a lower material cost.
4. Key Technical Advantages of Normal Grade APET Carrier Tape
4.1 Dimensional Precision
A thickness tolerance of ±0.015 mm and width tolerance of ±1.0 mm allow Normal grade carrier tape to run reliably on automated pick-and-place and reel-winding equipment without recalibration, minimizing downtime on high-speed lines.
4.2 Maximum Optical Clarity
Because no conductive carbon black or static-dissipative surfactant is compounded into the resin, Normal grade sheet typically exhibits the highest light transmittance of the three grades — useful where visual inspection, branding visibility, or aesthetic presentation of the carried component matters.
4.3 Thermoplastic Processability
Normal grade APET retains full thermoforming versatility, supporting custom cavity embossing, pocket forming, and die-cutting within the standard 130–160 °C processing window without loss of mechanical properties.
4.4 Structural Stability
The consistent 1.35 g/cm³ density provides predictable rigidity for supporting components during handling, stacking, and transport, while the material's controlled permeability offers reasonable protection from moisture ingress under normal storage conditions.
4.5 Cost Efficiency at Scale
For high-volume packaging runs where ESD protection is not a specification requirement, Normal grade eliminates the incremental material cost of conductive or anti-static additives — a meaningful saving across large production orders.
5. Application Areas
APET Normal Carrier Tape is applied wherever dimensional carrier stability is needed but ESD sensitivity is not a governing factor:
- General component packaging: Passive components, hardware fasteners, and mechanical parts with high ESD-withstand ratings.
- Precision instrument trays: Optical, medical, and precision mechanical parts requiring dimensional carriers without electrical requirements.
- Retail and point-of-sale packaging: Where the clarity and rigidity of carrier-tape-grade APET support small-item blister or clamshell presentation.
- Printing and graphics substrates: Structural base sheet for label stock, transparent overlays, and window packaging.
- Non-sensitive electronic accessories: Cable assemblies, connectors, and enclosures without ESD classification.
For applications that do involve ESD-sensitive semiconductors, refer instead to the conductive or anti-static grades detailed on the main APET Carrier Tape Sheets product page.

9. How to Decide If Normal Grade Is Right for Your Application
Ask the following questions before specifying Normal grade APET carrier tape:
- Does the packaged component carry an ESD sensitivity classification (e.g., JEDEC/HBM rating)? If yes, consider anti-static or conductive grade instead.
- Is maximum optical clarity important for automated or manual visual inspection? Normal grade offers the highest transmittance of the three grades.
- Is the packaging run large-volume and cost-sensitive with no ESD requirement? Normal grade typically offers the best cost-per-meter.
- Will the carrier be used for structural, mechanical, or general retail packaging rather than semiconductor handling? Normal grade is generally the appropriate default.
When in doubt, request test samples in all three grades and validate against your component's ESD sensitivity documentation before committing to a production order. The APET Carrier Tape Sheets product page provides full specifications across all three electrical grades for side-by-side reference.
