Challenge

A major U.S. grocery chain was using traditional stretch film overwrappers that required continuous heating throughout the day. This constant energy draw led to excessive electricity consumption and high operating costs, without delivering any added productivity benefits.

Solution

EGC implemented an advanced thermal management solution utilizing proprietary NTC technology. Unlike conventional systems, the seal plate operates on an on-demand basis—activating only when a package needs to be sealed and shutting off immediately afterward.

This system also delivers rapid thermal response, heating the seal plate to 300°F in just three seconds and cooling quickly between cycles.

Results

• Reduced energy consumption by 75–80%
• Delivered over $1.5 million in annual energy savings
• Maintained equivalent production speed and output
• Eliminated unnecessary continuous heating, improving efficiency

After a successful six-month test period, the grocery chain deployed the upgraded system across all store locations—demonstrating both scalability and long-term reliability.
