Benefits Gained
• Controlled delamination for greater peel reliability.
• Excellent sealability.
• Toughness.
• Puncture and abrasion resistance.
• Reliable seals –- even through contamination.
Materials Selected and Why
Because Surlyn® provides superior hot-tack strength and excellent sealability, it allowed Curwood to "bury" the polyethylene layer that does the actual peeling in this application. Called a controlled delamination, the patented process provides greater peel reliability and permits use of a wider range of machine heat seal temperatures.
