Surlyn resin is a plasma bonded polymer of ethylene (methyl) acrylic acid zinc salt, sodium salt, and lithium salt, which is polymerized by DuPont using a unique production process.
1、The characteristics of Surlyn resin:
1. The best all-around sealing material in the packaging industry.
2. The low heat sealing temperature allows for faster packaging line speed and improves packaging line production efficiency.
3. Excellent thermal adhesive strength and the widest range of thermal adhesive temperatures.
4. Excellent formability and deep drawing performance.
5. The widest temperature range for heat sealing.
6. Clear transparency enhances the appearance appeal of the packaging.
7. Oil resistant, grease resistant, solvent resistant, and resistant to chemical substances.
8. Excellent performance in sealing pollutants (reducing packaging waste rate and shelf cracking rate).
9. Excellent wear resistance and puncture resistance.
10. Directly coated on paper and aluminum foil, with excellent adhesion.
