FAQ
Q: What makes PSA hot melt different from standard EVA hot melt?
A: PSA hot melt remains permanently tacky at room temperature, forming instant, pressure-activated bonds without curing, making it ideal for label, tape, and film applications where immediate adhesion is critical for high-speed converting operations.
Q: How do I choose between permanent and removable PSA formulations?
A: Our technical team, leveraging 23+ years of OEM/ODM expertise, evaluates your substrate, dwell time, and removal requirements to engineer bespoke formulations with tailored tack and cohesive strength for your specific manufacturing process.
Q: What is your MOQ for PSA hot melt adhesive orders?
A: We offer flexible MOQs starting at 500kg for B2B clients, with factory-direct pricing and scalable production capacity to support both qualification trials and continuous high-volume converting operations.
Q: Can you customize PSA formulations for specific coating equipment?
A: Yes, since 2001 we've engineered PSA grades optimized for slot-die, gravure, and roll-coating systems, ensuring seamless integration, consistent coat weight, and maximum throughput on modern production lines.
Q: What quality certifications do your PSA adhesives hold?
A: Our PSA products meet FDA, REACH, and RoHS standards, with FDA-compliant options for indirect food contact; we provide COA and MSDS for every factory-direct batch.
Q: How should PSA be stored to maintain tack performance?
A: Store in sealed, moisture-proof packaging below 35°C away from direct sunlight; our PSA adhesives maintain stable viscosity and adhesive properties for 18-24 months, ensuring reliable supply chain inventory management.
Q: What causes PSA to lose tack over time, and how can we prevent it?
A: Ageing, contamination, or improper storage can reduce performance; our premium formulations from top-tier raw materials ensure long-term stability, and our technical support team provides detailed storage and handling guidelines.
Q: Are your PSA hot melts compatible with high-speed label printing and die-cutting?
A: Engineered for converting efficiency, our PSA formulations provide consistent coat weight, excellent die-cutability, and clean matrix stripping at speeds exceeding 100 meters/minute on industrial label presses.
Q: Do you offer technical support and samples for PSA adhesive trials?
A: Our application engineers provide complimentary 1-5kg samples shipped within 5 business days, plus on-site support and remote troubleshooting to optimize coating parameters and ensure seamless production integration.
Q: Can PSA hot melt be used for medical and skin-contact hygiene products?
