How to Choose Label Materials for Food/Pharmaceutical/Electronic Products? Cross-Industry Compliance Comparison of 3 Sectors
💡 💡 At a Glance
Food label emphasizes safety compliance, pharmaceutical label requires sterilization traceability, electronic label demands temperature resistance and insulation.
Last week, a client doing cross-industry products asked me: "My product line covers food + pharmaceutical + electronics — can I use the same label for all of them?"
I said: "No — the 3 industries have completely different compliance requirements. Mixing them = risk of being pulled from the shelves."
He said, "Can you be more specific?"
I said: "GB 4806 (food) + ISO 11607 (pharmaceutical) + RoHS (electronics) — the 3 national standards are completely different. This article won't discuss universal materials — it covers the compliance + material combinations for the 3 industries, telling you for each industry 'what you must use + what to avoid'."

Example: (01) 06901234567890 (11) 240115 (17) 280115 (10) ABC123
Industry 3: Label Materials for Electronic Products
Core Compliance: RoHS + CE + 3C
RoHS Includes: 6 hazardous substances (lead, mercury, cadmium, hexavalent chromium, PBB, PBDE)
CE: EU compliance mark (self-declaration)
3C: China Compulsory Certification
3 Types of Electronic Label Materials

FAQ
What materials are used for food labels?
3 types of food label materials must pass GB 4806 certification: (1) Food-grade coated paper + food-grade adhesive (most common, 0.1-0.3 RMB per sheet); (2) Food-grade synthetic paper (waterproof and moisture-proof, suitable for frozen/cold chain); (3) Food-grade metallized paper (high-end gift boxes). All 3 types use food-grade soybean ink (regular ink cannot be used). PVC (contains chlorine) and PET (some) are prohibited.
What materials are used for pharmaceutical labels?
3 types of pharmaceutical label materials must pass ISO 11607 + UDI coding: (1) Medical paper + sterilization indicator color block (ethylene oxide/irradiation compatible); (2) Medical composite film (PET + PE composite, high seal strength); (3) Medical Tyvek paper (high-density polyethylene, strong + breathable). All 3 types require no deformation after sterilization + clear UDI coding. UDI coding contains two parts: HI (device identifier) + PI (production identifier).
What materials are used for electronic product labels?
3 types of electronic label materials must pass RoHS + CE + 3C: (1) PI polyimide (resistant to 300°C reflow soldering, highest grade); (2) PET (resistant to 120-200°C, mainstream for electronic components); (3) Synthetic paper (PP, ordinary electronic products). All 3 types require anti-static treatment + moisture-proof. 3 types not recommended: (1) PVC (contains chlorine, prohibited in some countries); (2) Paper labels (easily damaged in humid electronic environments); (3) Laser paper (anti-counterfeiting function is redundant).
What are the differences between food/pharmaceutical/electronic labels?
3 dimensions of differences: (1) Compliance — Food GB 4806 / Pharmaceutical ISO 11607 + UDI / Electronic RoHS + CE + 3C; (2) Cost — Food 0.1-0.5 RMB / Pharmaceutical 0.5-2 RMB / Electronic 0.3-1.5 RMB; (3) Testing — Food 6 items / Pharmaceutical 12 items / Electronic 8 items. The 3 industries cannot be mixed; mixing = risk of removal or recall.
What happens if industry labels are selected incorrectly?
3 types of consequences: (1) Wrong material for food — removal from shelves + fine of 10,000-30,000 RMB (GB 4806 violation); (2) Wrong material for pharmaceuticals — patient safety risk + recall + drug administration penalty; (3) Wrong material for electronics — CE invalidation / customs seizure / overseas recall. 3 suggestions: submit for testing 1-2 months before first launch, testing fee 1,000-20,000 RMB per item, to avoid greater losses.
