Hot Melts Hold Fast
Understanding the variables involved in pressure-sensitive label construction can help optimize labeling operations and reduce costs.
1. SIS polymer with diblock content, plus tackifier based on C5 resin (non-hydrogenated), plus aliphatic plasticizer, plus aromatic phenolic antioxidant.
From this basic formulation, individual components were varied one or two at a time for testing, as follows:
2. SIS polymer with no diblock content
3. SBS polymer, tackifier with (25:75) C9/C5 resin
4. SIS polymer with high styrene content
5. SEBS polymer, hydrogenated
6. Tackifier, C9 resin, 100 percent hydrogenated
7. Polymer and tackifier, hydrogenated
8. Rosin ester tackifier
9. Tackifier, (25:75) C9/C5 resin
10. Napthenic oil plasticizer
