How to Choose UV Adhesive for Food Contact Plastic Assembly? EU 10/2011 Guide
Food contact plastic assembly is one of the most easily blocked steps for EU market access. Choosing the wrong UV adhesive doesn’t just mean bonding failure — it can result in an entire batch being rejected due to migration limit exceedances.
This guide uses a “problem + market context + solution” approach, combined with ODAKE food grade UV adhesive test data, to give you a selection method aligned with EU 10/2011 requirements.
1. The Problem: Why Is Food Contact Plastic Assembly Hard for UV Adhesive Selection?
Common Compliance Traps
| Trap | Consequence |
|---|---|
| Supplier claims FDA certification, but EU 10/2011 applicability unclear | Product detained at EU customs |
| UV adhesive migration exceeds limits after cure | Batch rejection, fines |
| UV adhesive selected for opaque substrates that block UV light | Production line stoppage, delivery delays |
| Poor adhesive-plastic compatibility, cracking over time | Customer complaints, recalls |
Dual Requirements for Food Contact Plastic Assembly
Food contact plastic assembly demands two extra thresholds compared to ordinary industrial bonding:
Threshold 1: Regulatory compliance. EU 10/2011 is the core regulation for food contact plastics in the EU, requiring that all plastic materials and components in contact with food have substance migration within safety limits. Adhesives used in assembly are subject to the same constraints.-2-3
Threshold 2: Process feasibility. UV adhesive requires at least one transparent substrate for UV light to reach the bond line. Among food contact plastics, PC, PET, clear PVC, PMMA, and clear ABS meet light transmission requirements; PP, PE, and HDPE are not suitable.-13
2. Market Context: Why EU 10/2011 Matters More Now
EU Regulatory Scrutiny Continues to Tighten
EU 10/2011 has been continuously updated since implementation. The latest amendment (Regulation (EU) 2025/351) further clarifies rules for the authorized substances list and strengthens control of non-intentionally added substances (NIAS). This means adhesives used in food contact plastic assembly face stricter scrutiny of ingredient compliance and migration safety.-3
Real Pressure on Chinese Exporters
For Chinese companies exporting food contact plastic products to the EU, EU 10/2011 compliance is a hard threshold. Per the regulation, plastic materials and articles must undergo chemical and sensory testing to confirm migration limits before being placed on the EU market, and must be accompanied by a Declaration of Compliance. If the adhesive supplier cannot provide complete compliance documentation, downstream assemblers risk the entire batch being unable to clear customs.-2
Advantages of UV Adhesives in Food Contact Plastic Assembly
Compared to solvent-based adhesives, UV adhesives offer: solvent-free, 100% solid content, fast curing. Solvent-free means lower VOC emissions and fewer potential migration risk sources. This is why more food contact plastic assembly lines are transitioning to UV adhesives.
3. Solution: ODAKE Food Grade UV Adhesive Selection
ODAKE offers three UV adhesives suitable for food contact plastic assembly, each targeting different process requirements:
Option 1: CT8886 (Medium Viscosity, Large Gap Filling)
| Parameter | Value |
|---|---|
| Viscosity @25℃ | 3,500-7,600 mPa·s |
| Chemistry | Urethane Acrylate |
| Curing Method | UV / Visible Light |
| Shear Strength (PC/PC) | 11.5 N/mm² (substrate failure) |
| Temperature Range | -54℃ to +149℃ |
| Compatible Materials | PC, PVC, ABS, TPU |
Application: Plastic component assembly requiring larger gap filling, such as food container housing to base, clear lid to container structural bonding.-1
Option 2: CT8887A (Low Viscosity, Precision Dispensing)
| Parameter | Value |
|---|---|
| Viscosity @25℃ | 650±100 mPa·s |

| Temperature Range | -40℃ to +100℃ |
| Compatible Materials | PC, PVC, ABS |
Application: Precision small-part assembly requiring low-viscosity adhesive penetration into micro-gaps, such as small food container fittings and clear window bonding.-4
Option 3: CT8888C (Medium Viscosity, Higher Temperature Resistance)
| Parameter | Value |
|---|---|
| Viscosity @25℃ | 1,800-2,200 mPa·s |

Application: Food contact plastic assembly requiring higher temperature resistance, such as applications that may undergo hot cleaning or hot filling.-6
Selection Decision Tree
Food Contact Plastic Assembly UV Adhesive Selection
├── Is substrate transparent?
│ ├── Yes (PC/PET/PVC/ABS/Glass) → UV adhesive suitable
│ └── No (PP/PE/HDPE) → UV adhesive not suitable
├── Gap size?
│ ├── Small gap (<0.2mm) → CT8887A (low viscosity)
│ └── Large gap (0.2-0.5mm) → CT8886/CT8888C (medium viscosity)
└── Temperature requirement?
├── Standard (≤150℃) → CT8886
└── High temp (≤180℃) → CT8888C
4. EU 10/2011 Compliance Checklist: Three Things to Confirm
1. Can the supplier provide migration test data?
EU 10/2011 requires food contact plastic materials to undergo overall and specific migration testing. When selecting UV adhesive, request migration data based on EU 10/2011 test methods — not just “FDA certification.” FDA and EU 10/2011 use different test methods and limit systems and cannot substitute for each other.-2
2. Are the adhesive ingredients on the authorized substances list?
EU 10/2011 Annex I lists authorized substances (monomers, additives, polymer production aids, etc.) for food contact plastics. The adhesive formulation ingredients should be traceable to this list or confirmed via the supplier’s Declaration of Compliance.-3
3. Is there a Declaration of Compliance (DoC)?
Per EU 10/2011 Annex IV, food contact plastic materials must be accompanied by a Declaration of Compliance in B2B transactions. When selecting adhesive, confirm whether the supplier can provide a DoC for that specific product.-2
5. FAQ
Q1: Is “food grade UV adhesive” the same as EU 10/2011 compliance?
A: Not exactly. “Food grade” is a colloquial term; EU 10/2011 is a specific regulatory framework. An adhesive may meet FDA standards but not necessarily EU 10/2011 migration limits and authorized substance requirements. For EU market access, EU 10/2011 is the reference.
Q2: Can PP food containers be assembled with UV adhesive?
A: Not recommended. PP has extremely low surface energy, resulting in poor UV adhesive adhesion; PP is also typically opaque or semi-transparent, preventing UV light from reaching the bond line. For PP bonding, consider other curing methods or surface treatment.-13
Q3: CT8886 or CT8887A — which to choose?
A: For larger gaps requiring filling capability, choose CT8886 (viscosity 3,500-7,600). For precision small parts requiring low-viscosity penetration, choose CT8887A (viscosity 650).
Q4: How to obtain EU 10/2011 compliance documents for ODAKE UV adhesives?
A: Contact ODAKE for migration test data, ingredient compliance statements, and Declaration of Compliance (DoC) for specific products.
6. Summary
How to choose UV adhesive for food contact plastic assembly? Remember this formula:
Confirm substrate transparency (UV prerequisite) → Confirm EU 10/2011 compliance (migration test + authorized substances + DoC) → Select by gap and temperature (CT8887A precision / CT8886 filling / CT8888C high-temp) → Verify certification documents
