Switching PSA emulsion suppliers is not a casual decision. A bad adhesive affects your entire production — coat quality, die-cutting, label application, and ultimately your customer’s product on shelf. Here is a practical checklist for evaluating any new PSA supplier in India.
1. Manufacturing Capacity and Consistency
A supplier with a small, manually operated plant will struggle to maintain batch-to-batch consistency. Ask for their monthly production capacity, number of reactors, and whether they run in-process quality checks on every batch. Focus Polymers produces 1,200+ MT/month under ISO 9001:2015 certification with in-process and finished goods QC on every batch.
2. Technical Data Sheets and Test Reports
Any serious supplier should provide a TDS with peel, tack, and shear data on standardised substrates — not just viscosity and solids. If a supplier cannot provide 180° peel on stainless steel and loop tack data, that is a red flag. For BOPP work, see the specific test data that matters for BOPP applications.
| What to Ask For | Red Flag if Missing |
|---|---|
| 180° peel on stainless steel | Yes |
| Loop tack data | Yes |
| Shear resistance | Yes |
| Viscosity and solids only | Not enough — ask for more |
| REACH compliance declaration | Yes — for export supply chains |
3. Grade Range
A supplier with only 2–3 grades cannot serve diverse converter needs. You want a supplier who has grades for paper, BOPP, PET, foam, and specialty applications — so you can consolidate your supply base as your product range grows.
4. Sample and Trial Support
Will they send samples without a purchase commitment? Will they provide technical support during your coating trials? A supplier who disappears after the sale is a liability. Always run a coating trial before committing to commercial volumes.
5. Supply Reliability
Raw material shortages have disrupted PSA supply chains repeatedly in recent years. Ask your supplier about their raw material stocking policy and lead times. Suppliers with strategic RM stocks or integrated backward linkages are lower risk.
6. Regulatory Compliance
If you export labels or supply brand owners with global operations, you need adhesives that comply with EU REACH, RoHS, or food-contact regulations. Ask for compliance declarations in writing — not just verbal assurances.
7. Packaging and Logistics
PSA emulsions are typically supplied in 200L HDPE drums or 1000L IBC totes. Check minimum order quantities, packaging options, and freight terms — especially if you are outside major metros.
