Application Description

Surlyn® is used as a sealant layer in both the top, non-forming film and the bottom forming film of the EZ Peel® package for Sorrento's mozzarella cheese in the popular one-pound size.

Benefits Gained

· Superior hot-tack strength

· Excellent sealability

· Toughness

· Puncture and abrasion resistance

· Seal through contamination

Materials Selected and Why

Because Surlyn® adds 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 reliability of peel and permits use of a wider range of machine heat seal temperatures.
